Chapter6 provides a detailed description of the SHINE confinement strategy for limiting the potential for release of radioactive materials to occupied spaces and the environment. | |||
9a2.1.1.1 Design Bases The design bases of the RV systems include: | |||
Provide confinement at ventilation zone 1 confinement boundaries. See Chapter6 for a description of the specific portions of the RVZ1 system credited as being a confinement boundary. | |||
Provide isolation at the RCA boundary. See Section7.5 for a description of the specific portions of the RVZ1, RVZ2, and RVZ3 systems that provide the isolation functions. | |||
Confine airborne radiological materials in an accident scenario. | |||
Provide ventilation air and condition the RCA environment for workers. | |||
Provide makeup air and condition the RCA environment for process equipment. | |||

Exhaust hazardous chemical fumes. | |||
Nonsafety-related portions of the RV systems are constructed to the requirements of ChaptersSPS 362, SPS363 and SPS364 of the Wisconsin Administrative Code. Nonsafety-related piping is designed, installed, tested and inspected in accordance with American Society of Mechanical Engineers (ASME) B31.9, Building Services Piping (ASME, 2017). | |||
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-2 Rev. 3 Details of the inspection and testing requirements of safety-related RV systems are provided in Subsection9a2.1.1.5. | |||
9a2.1.1.2 | |||
===System Description=== | |||
Radiological Ventilation Zone 1 RVZ1 is divided into two subsystems: RVZ1r and RVZ1e. A flow diagram of RVZ1r is provided in Figure9a2.1-2. A flow diagram of RVZ1e is provided in Figure9a2.1-3. | |||
RVZ1r provides cooling for systems within the irradiation unit (IU) cell and the target solution vessel(TSV) off-gas system(TOGS) cell. RVZ1r recirculates, filters, and cools air within the IUcell and the TOGS cell. The system includes two fan coil units and associated ductwork and dampers per each set of lU/TOGS cells. Each set of RVZ1r units is located within the cooling room and forms a portion of the confinement boundary for the lU/TOGS cells that it serves. | |||
RVZ1r provides sampling, ventilation, and cleanup connections for the primary confinement. | |||
RVZ1e exhausts air from the areas with a high potential for contamination in the facility. The air is filtered and directed out of the main production facility through the exhaust stack. The subsystem includes fans, filters, ductwork, dampers, and high efficiency filter banks. It also includes the necessary transfer ductwork to allow makeup from the RCA general area into the exhausted areas. | |||
RVZ1e is designed to maintain ventilation zone 1 areas at a lower pressure than ventilation zone2 areas. The design inhibits backflow with the use of backflow dampers at the discharge of the RVZ1e and RVZ2e exhaust fans in order to minimize the spread of contamination. RVZ1e ductwork provides sampling locations for radiation detectors, fire detection equipment, stack release monitoring, and an exhaust stack connection point for RVZ2e and the process vessel vent system(PVVS). | |||
The RVZ1 serves the following areas: | |||
IU cells TOGS cells Tritium purification system (TPS) process equipment Primary closed loop cooling system (PCLS) expansion tank Uranium receipt and storage system (URSS) glovebox Radioactive liquid waste immobilization (RLWI) shielded enclosure Supercell Target solution preparation system (TSPS) glovebox Target solution dissolution tanks Target solution preparation tank Radiological Ventilation Zone 2 RVZ2 includes three subsystems:RVZ2e, RVZ2s, and RVZ2r. A flow diagram of RVZ2e is provided in Figure9a2.1-4. A flow diagram of RVZ2s air handling units(AHUs) is provided in Figure9a2.1-5. A flow diagram of RVZ2s distribution and RVZ2r is provided in Figure9a2.1-6. | |||
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-3 Rev. 3 RVZ2e exhausts air from the general areas of the RCA. The subsystem includes fans, filters, ductwork, dampers, and high efficiency filter banks. It also includes the necessary transfer ductwork to allow makeup from the RCA general area into the exhausted rooms. The transfer ductwork is located in the following spaces: | |||
from the irradiation facility(IF) general area to the TPS room; from each of the cooling rooms to the IF general area; from the analytical lab to the quality control (QC) lab; from the QC lab to the radioisotope production facility (RPF) general area; from the RPF general area to the transfer aisle; from the storage room to the preparation room; from the RPF general area to the RLWI skid; and from the transfer aisle to the radioisotope process facility cooling system (RPCS) room. | |||
RVZ2 provides ventilation and humidity control for ventilation zone 2 rooms within the RCA. | |||
RVZ2e provides an exhaust path for the QC lab and analytical laboratory fume hoods within the RCA and maintains the QC lab and analytical labs at positive pressure with respect to the ventilation zone 2 general area. The system is designed to maintain the RCA at a lower pressure than areas outside of the RCA. The RVZ2e design inhibits backflow within ductwork that could spread contamination. RVZ2e ductwork provides sampling locations for engineered safety features actuation system (ESFAS) radiation detectors and fire detection equipment. | |||
RVZ2s supplies conditioned outside air into the RCA to provide ventilation and to make up for RVZ1e and RVZ2e exhaust volumes. The system includes AHUs, filters, ductwork, and dampers. RVZ2s provides cooling, heating, humidification for all systems within ventilation zone2 as well as maintains the QC lab and analytical labs at positive pressure with respect to the ventilation zone 2 general area. | |||
RVZ2r recirculates, filters, and conditions air within the RCA. The system includes AHUs, filters, ductwork, and dampers. The RVZ2r units are located within the RCA. RVZ2r provides additional cooling for systems within ventilation zone 2. RVZ2r is also used to cool air being supplied to the supercell, which reduces the flow rate required to cool the equipment within the supercell. The filters and bubble-tight dampers on the inlet side of the supercell are part of RVZ1e. | |||
Areas served by RVZ2 include: | |||
TPS fume hoods QC lab hood Analytical lab hood RCA exhaust filter room Access control area Don/doff rooms Decontamination room Labyrinths Analytical lab QC lab Workspace Transfer aisle RPCS room Storage rooms | |||
.1. | Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-4 Rev. 3 Preparation room Tool crib Vestibule Primary cooling rooms IF general area Neutron driver assembly system (NDAS) service cell TPS room Supercell Radiological Ventilation Zone 3 Under normal operating conditions, RVZ3 transfers air from ventilation zone 4 to ventilation zone3 then from ventilation zone 3 to ventilation zone 2 via engineered pathways. A flow diagram of RVZ3 is provided in Figure9a2.1-7. Under accident conditions, bubble tight dampers close, isolating ventilation zone2. The design of RVZ3 inhibits backflow within ductwork that could spread contamination. Transfer ductwork from ventilation zone 3 to ventilation zone 2 is provided for the following spaces: | ||
from the shipping/receiving alcove to the IF general area; from the shipping/receiving alcove to the transfer aisle; from the main RCA ingress/egress to the access control; from the RPF emergency exit to the RPF general area; from the IF emergency exit to the IF general area; and from the mezzanine emergency exit to the IF general area. | |||
9a2.1.1.3 System Operation RVZ1e areas draw ambient supply air from adjacent ventilation zone 2 spaces, except for the supercell. During normal operation, areas ventilated by RVZ1e are maintained at negative pressure with respect to their surrounding ventilation zone 2 spaces. The supercell is supplied air directly from RVZ2r. The air supplied to the supercell is exhausted by RVZ1e. | |||
RVZ1e contains redundant fans that are capable of continuous operation. During normal operation, one fan is operating while the other fan is on standby. If the operating fan fails, the standby fan will start automatically. | |||
The exhaust from RVZ1e areas collects in the RVZ1e system duct header and then is drawn through the final filter banks on the mezzanine. These filter banks contain high efficiency particulate air (HEPA) filters and carbon adsorbers upstream of the building isolation dampers. | |||
These filters and adsorbers are equipped with differential pressure monitoring equipment and are periodically monitored by operations personnel. The building isolation dampers are safety-related automatic isolation dampers controlled by ESFAS. These dampers are located at the RCA boundary, upstream of the exhaust fans and exhaust stack. | |||
.1 | Negative pressure is maintained in the ductwork to control contamination and maintain pressure gradients. System operation between RVZ1e, RVZ2e, and RVZ2s is coordinated such that the overall airflow and pressure gradients are maintained. The pressure gradients create flow patterns that direct air towards areas of increasing contamination potential. This is maintained by the variable frequency drives (VFDs) on the exhaust fans. Minimum airflow will be maintained during normal system operation. | ||
.1. | |||
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-5 Rev. 3 During upset conditions, affected sections of the RVZ1e, RVZ2s, and RVZ2e ventilation systems are isolated as required for the specific event or indication. Bubble tight dampers close, based on detection of radiation more than 60 times normal background radiation levels. The RVZ1e supply flow path to the supercell includes nonsafety-related HEPA and carbon filters. The RVZ1e exhaust flow path from the supercell includes nonsafety-related HEPA filters and safety-related carbon filters. The remaining RVZ1e flow paths that exhaust confinements for fission products contain nonsafety-related HEPA and carbon filters. The RVZ1e safety-related, redundant bubble-tight dampers are situated as near to the confinement boundary as practical. | |||
The IU cell exhaust flow path of RVZ1e provides ventilation of the IU cell and TOGS cell via the PCLS expansion tank headspace. This path is equipped with radiation monitoring instrumentation and redundant isolation valves. Between the RVZ1e IU cell radiation instrumentation and RVZ1e IU cell isolation valves is an isolation lag tank. If radiation measurements exceed 60 times normal background radiation, the TSV reactivity protection system (TRPS) initiates an IU Cell Safety Actuation, which closes the RVZ1e IU cell isolation valves. The isolation lag tank provides an exhaust gas delay time greater than the closing time of the valves. | |||
Upon loss of power, loss of signal, or ESFAS initiation of confinement, dampers seal the affected confinement areas within 30seconds. | |||
The RVZ1r fan coil units (FCUs) are capable of continuous operations. The RVZ1r recirculates, and cools air within the IU cell and TOGS cell. The IU cell and TOGS cell are established as low leakage boundaries. | |||
RVZ2e fans are capable of continuous operation. RVZ2e exhausts the various normally occupiable rooms within the RCA as well as fume hoods, filters the air via HEPA filter banks and discharges to the facility stack. Exhaust headers are maintained at a negative pressure by the VFD. Negative pressure is maintained in the ductwork to control contamination and maintain pressure gradients. The exhaust from RVZ2 areas collects in the RVZ2 system duct header and then is drawn through final HEPA filters and carbon adsorbers prior to discharge to the exhaust stack. | |||
During normal operation, ventilation zone 2 areas are maintained at negative pressure with respect to RVZ3 airlocks. The speed of the RVZ2e exhaust fans is controlled to maintain a negative pressure setpoint in the RVZ2e exhaust header. Minimum airflow will be maintained during normal system operation. | |||
RVZ2s AHUs are capable of continuous operation. Ventilation zone 2 areas are directly supplied air via the RVZ2s AHUs. The AHUs supply conditioned, 100percent outside air. Each AHU contains filters, pre-heat and cooling coils, and supply fans. The supply system includes redundant AHUs. If a single AHU fails, the standby AHU will start automatically. The AHUs normally supply a constant volume of conditioned air to RVZ2 areas. | |||
The RVZ2s supply duct contains safety-related automatic isolation dampers controlled by ESFAS. These dampers are located at the RCA boundary. | |||
RVZ2r AHUs are capable of continuous operation. The RVZ2r AHUs further condition the air in the RCA general area to comfort levels. | |||
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-6 Rev. 3 The RVZ1e and RVZ2e subsystems combine downstream of each subsystems respective filter banks, RCA isolation bubble-tight dampers, and exhaust fans, as shown in Figure9a2.1-8. The PVVS delay bed discharge is also combined with the RVZ1e and RVZ2e flow downstream of the exhaust fans and upstream of the stack release monitor. The discharge of the stack is approximately 10feet above the roofline of the facility and will maintain a minimum discharge velocity of 3,000fpm. | |||
.1. | 9a2.1.1.4 Instrumentation and Control The RV systems are designed such that the process integrated control system (PICS) monitors the system equipment, flow rates, pressures, and temperatures. Instrumentation monitors the ventilation systems for off-normal conditions and signal alarms as required. The PICS starts, shuts down, and operates the RV system in normal operating modes. Coordinated controls maintain negative pressurization to create flow patterns that direct air toward areas of increasing contamination potential. | ||
.1. | PICS monitors the differential pressures across all the filters in the RVZ1e and RVZ2e filter banks and produces an alarm if the differential pressure of any filter is above its established limit. | ||
.1. | 9a2.1.1.5 Inspection and Testing The ventilation systems are balanced upon installation. Control systems are tested to assure that control elements are calibrated and properly adjusted. Safety-related isolation dampers are inspected and tested as required by, and in accordance with, SectionDA of ASME AG-1, Code on Nuclear Air and Gas Treatment (ASME,1999). Safety-related ductwork will be inspected and tested as required by, and in accordance with, SectionSA of ASME AG-1 (ASME,1999). | ||
9a2.1.1.6 Nuclear Criticality Safety Subsection6b.3.2.7 provides a discussion related to the nuclear criticality safety requirements for the URSS glovebox ventilation. Subsection6b.3.2.4 provides discussion related to the nuclear criticality safety requirements for the TSPS glovebox ventilation. | |||
9a2.1.1.7 Technical Specifications Certain material in this subsection provides information that is used in the technical specifications. This includes limiting conditions for operation, setpoints, design features, and means for accomplishing surveillances. In addition, significant material is also applicable to, and may be used for, the bases that are described in the technical specifications. | |||
9a2.1.2 NON-RADIOLOGICAL AREA VENTILATION SYSTEM The non-radiological area ventilation system is the facility ventilation zone 4 (FVZ4) system. | |||
.1. | Ventilation zone 4 consists of areas which are located within the main production facility, but outside of the RCA. The FVZ4 system is completely independent of the RV systems described in Subsection9a2.1.1. The FVZ4 system supply AHUs draw at least 10percent outside air to make up for air exhausted and exfiltrated. The outside air is mixed with recirculated air and conditioned through the AHUs before being supplied to FVZ4 areas. FVZ4 exhaust streams exhaust directly | ||

9a2.1.2.2 | |||
===System Description=== | |||
The FVZ4 system is nonsafety-related. The FVZ4 system is a variable air volume (VAV) type heating, ventilation and air conditioning (HVAC) system that supplies conditioned air into ventilation zone 4 areas. The FVZ4 system supplies outside air as required and exhausts air to maintain indoor design conditions in ventilation zone 4 areas. The FVZ4 provides transfer air into exhausted ventilation zone 4 rooms and into the RVZ3 system airlocks. The FVZ4 system is comprised of the following three subsystems: | |||
FVZ4 supply and transfer air subsystem (FVZ4s) | |||
FVZ4 exhaust subsystem (FVZ4e) | |||
.1. | FVZ4 room cooling recirculation subsystem (FVZ4r) 9a2.1.2.3 System Operation FVZ4 Supply and Transfer Air Subsystem (FVZ4s) | ||
The supply air subsystem provides conditioned air for workers and equipment in the non-RCA portion of the facility, makeup air for exhaust air systems, and outside air to maintain positive pressure with respect to the RCA. The distribution of the FVZ4s is provided in Figure9a2.1-9. | |||
The supply AHU draws outside air to make up for air exhausted and exfiltrated. The outside air is mixed with the return air recirculated from the spaces served by FVZ4s and conditioned through the AHU before being supplied to the non-RCA areas of the facility. Each AHU contains filters, heating and cooling coils, and supply fans. The FVZ4s subsystem includes two AHUs, each sized for 100percent of total system capacity. One FVZ4s subsystem AHU operates at a time with the other unit on standby. The AHUs normally supply a variable volume of conditioned air to ventilation zone 4 areas, with a minimum flow determined by ventilation requirements Dampers are provided to isolate the FVZ4s subsystem to each battery room and each uninterruptible power supply (UPS) room, independently, on an initiation signal from each locations fire suppression system. | |||

.1.4 | FVZ4 Exhaust Subsystem (FVZ4e) | ||
FVZ4e serves the following locations of the non-RCA area of the facility: | |||
.1.4 | Janitor closets Chemical storage Restrooms Battery rooms Control room The FVZ4e subsystem exhausts the battery rooms and UPS rooms within ventilation zone 4 to maintain the hydrogen concentration below 2percent and the temperature under 120°F. Upon a loss of power, the battery rooms will be exhausted by dedicated fans powered by the standby generator system (SGS). | ||
Dampers are provided to isolate the FVZ4 exhaust air subsystem to each battery room and each UPS room, independently, on an initiation signal from each locations fire suppression system. | |||
The distribution of the FVZ4e subsystem is provided in Figure9a2.1-12. | |||
FVZ4 Room Cooling Recirculation Subsystem (FVZ4r) | |||
The FVZ4r subsystem recirculates and cools air within the human machine interface (HMI)/ | |||
telecommunication room and the process/server room. The system is made up of two split systems that cool the server space. The FVZ4r subsystem provides equipment status to the PICS. | |||
9a2.1.2.4 Radiation Protection and Criticality Safety There are no radiation contamination hazards or criticality safety hazards associated with the FVZ4 system. | |||
9a2.1.2.5 Instrumentation and Control The supply air subsystem HVAC controls operate through the PICS. The FVZ4 system is designed such that the PICS monitors and controls the non-RCA recirculation air subsystem ventilation equipment, flow rates, pressures, and temperatures. Instrumentation monitors the ventilation systems for off-normal conditions and signal alarms as required. | |||
The PICS performs the following functions relative to FVZ4: | |||
starts, shuts down, and operates FVZ4 in normal operating modes; monitors the return and supply temperature from the AHUs; and monitors the pressure differential across the filters. | |||
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-9 Rev. 3 9a2.1.2.6 Inspection and Testing The FVZ4 system is balanced upon installation. HVAC control systems are tested to assure that control elements are calibrated, adjusted, and in proper working condition. | |||
9a2.1.2.7 Technical Specifications There are no technical specification parameters associated with the FVZ4. | |||
9a2.1.3 FACILITY CHILLED WATER SYSTEM The facility chilled water system (FCHS) is a closed-loop, forced circulation system which provides chilled water to the cooling coils of the RVZ2s subsystem AHUs, which are located outside of the RCA. FCHS also provides chilled water to the cooling coils of the FVZ4 AHUs. The FCHS rejects heat to the atmosphere. | |||
9a2.1.3.1 Design Bases The design bases of the FCHS include: | |||
Circulate chilled water through the cooling coils of RVZ2s subsystem AHUs. | |||
Circulate chilled water through the cooling coils of the FVZ4 AHUs. | |||
The FCHS is constructed to the requirements in Chapters SPS 361 and SPS363 of the Wisconsin Administrative Code. | |||
9a2.1.3.2 | |||
===System Description=== | |||
The FCHS is nonsafety-related. Primary components of the FCHS include: | |||
Air-cooled chillers; Chilled water pumps, associated piping and valves, and makeup water and water treatment equipment; and An expansion tank. | |||
9a2.1.3.3 System Operation The system is powered by the normal electrical power supply system (NPSS) under normal operating conditions. | |||
The system is a variable closed-loop cooling system using VFDs on each centrifugal pump to supply a single pump header. Each chiller supply line maintains a modulating flow control valve capable of fully-open or fully-closed valve position. Each RVZ2s subsystem and FVZ4 AHU cooling fluid supply line maintains a modulating flow control valve capable of fully-open or fully-closed valve position. System flow, temperature, and differential pressures are utilized by an FCHS controller to signal valves, pumps, and chillers to come online, vary speed, or secure as necessary to meet system setpoints during normal system operation. | |||
PICS monitors the RVZ2s and FVZ4 airstream delivery temperatures. An FCHS controller monitors flow control valve position and delivers a signal to individual valves to adjust cooling | |||
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-10 Rev. 3 water flow rates in response to signals sent to the load instrumentation. A flow control valve is maintained on the system bypass line and is controlled by input signals from FCHS controller inputs made by chiller supply, RVZ2s, and FVZ4 modulating flow control valves. | |||
Each pumps VFD status is monitored by local chiller equipment for fault status and motor amps. | |||
When the FCHS controller registers that a pump is not running, and a stop command has not been issued from the control panel, an alarm is generated at the control panel and the standby pump is automatically started. | |||
Local chiller equipment monitors differential pressures across each chiller and the chillers running status. Upon communication of a fault alarm, an FCHS controller isolates that chillers modulating flow control valve and issues a start command to the back-up chiller. System pumps respond accordingly to the loading of the chillers via a local controller. Chiller fault alarms on multiple chillers initiates an automatic shutdown of the system through an FCHS controller. | |||
The system maintains alarms monitored by PICS and displays them at operator workstations for system volumes out of range. | |||
9a2.1.3.4 Radiation Protection There are no radiation contamination hazards associated with the FCHS. | |||
9a2.1.3.5 Instrumentation and Controls Instrumentation monitors the system for off-normal conditions and signal alarms as required. | |||
FCHS controls are nonsafety-related. | |||
The FCHS provides the necessary output signal to the PICS for the monitoring of heating water temperatures, pressures, and flow rates. | |||
9a2.1.3.6 Inspection and Testing The FCHS testing requirements for water piping, pipe supports, and valves are in accordance with ASME B31.9, Building Services Piping(ASME,2017).

Chapter 9 - Auxiliary Systems Handling and Storage of Target Solution SHINE Medical Technologies 9a2.2-1 Rev. 0 9a2.2 HANDLING AND STORAGE OF TARGET SOLUTION 9a2. | |||
==2.1 | ==2.1 INTRODUCTION== | ||
This section describes the handling and storage of target solution within the irradiation facility (IF). The chemical properties of the target solution are described in Section4a2.2, including uranium concentration, density, and pH. | |||
Detailed descriptions of the processes involving irradiated and unirradiated special nuclear material (SNM), including the byproduct material produced as a result of the irradiation of SNM, are provided in Section4b.4. Equipment, application of administrative controls, and design features related to the target solution lifecycle are also discussed in Section4b.4. A detailed description of the target solution lifecycle is provided in Section9b.2. | |||
Physical protection of the target solution from theft or diversion is ensured via the implementation of the Physical Security Plan, described in Section12.8. The primary closed loop cooling system (PCLS) removes heat from the target solution vessel (TSV), neutron multiplier, and components of the subcritical assembly system (SCAS) during irradiation of the target solution, as described in Section5a2.2. Radiological considerations during normal operations related to the handling and storage of target solution are described in Section11.1. An analysis of accident scenarios involving the mishandling or malfunction of target solution within the IF is provided in Subsection13a2.1.4. | |||
9a2.2.2 IRRADIATION FACILITY TARGET SOLUTION STORAGE AND HANDLING After target solution is prepared and qualified in the target solution preparation system (TSPS), it is transferred to the target solution hold tank prior to transfer into the TSV. Target solution is transferred from the target solution hold tank to the TSV via the TSV fill lift tank. | |||
The target solution hold tank is at an elevation below that of the TSV to prevent an accidental gravity-driven transfer of target solution to the TSV. The vacuum transfer system (VTS) is used to transfer the target solution to the TSV in a controlled manner, both with respect to fill rate and fill volume. A description of the incremental process used to fill the TSV is provided in Section4a2.6.1. Target solution batches that have been previously irradiated are returned to the target solution hold tank from processes in the hot cells or from the target solution storage tank. | |||
9a2.2.3 IRRADIATION FACILITY TARGET SOLUTION HANDLING EQUIPMENT The following is a list of major equipment that interacts with target solution in the IF. | |||
Target Solution Vessel Quantity: 8 Location: Inside irradiation unit (IU) cell TSV Dump Tank Quantity: 8 Location: Inside IU cell | |||
Chapter 9 - Auxiliary Systems Handling and Storage of Target Solution SHINE Medical Technologies 9a2.2-2 Rev. 0 9a2.2.4 STORAGE OF TARGET SOLUTION Storage of target solution in the IF is limited to storage in the TSV dump tanks following irradiation in the TSV. | |||
. | 9a2.2.5 CRITICALITY CONTROL FEATURES Protection against inadvertent criticality in the TSV dump tank is discussed in Subsection4a2.6.3. Protection against inadvertent criticality in the TOGS is discussed in Subsection4a2.8.5. Reactivity control for the SCAS is discussed in Section4a2.6. | ||
9a2.2.6 BIOLOGICAL SHIELDING The irradiation cell biological shield (ICBS) ensures that the projected radiation dose rates and accumulated doses in occupied areas within the IF do not exceed the limits of 10 CFR 20. | |||
Furthermore, the dose reduction by the ICBS supports the radiation exposure goals defined in the as low as reasonably achievable (ALARA) Program, as described in Section11.1. | |||
Section4a2.5 provides a detailed description of the ICBS. | |||
9a2.2.7 TECHNICAL SPECIFICATIONS Controls on target solution during handling and storage, including testing and surveillance, are described in the technical specifications. | |||
Chapter 9 - Auxiliary Systems Fire Protection Systems and Programs SHINE Medical Technologies 9a2.3-1 Rev. 1 9a2.3 FIRE PROTECTION SYSTEMS AND PROGRAMS 9a2.3.1 FIRE PROTECTION PLAN AND PROGRAM The Fire Protection Plan describes the overall facility Fire Protection Program (FPP). The FPP describes the fire protection organization and responsibilities, design and programmatic approach, and means to limit the probability and consequences of fire at the SHINE facility. The Fire Protection Plan establishes the requirements to be satisfied by the facility fire protection program. This plan establishes a program that represents an integrated effort involving components, procedures, analyses, and personnel used in defining and carrying out activities of fire protection. It includes system and facility design, fire prevention, fire detection, annunciation, confinement, suppression, administrative controls, inspection and maintenance, training, quality assurance, and testing. The established fire protection program elements, systems, structures, and components are subject to the SHINE Quality Assurance Program, as described in the Quality Assurance Program Description. The elements of the FPP work together to satisfy the requirements of applicable regulatory requirements presented in 10CFR50.48(a). The FPP is comprised of the following lower tier documents which are developed and maintained as part of the overall FPP. | |||
. | Fire Hazards Analysis (FHA); | ||
. | Safe Shutdown Analysis; Pre-Fire Plans; and Administrative controls (e.g.,implementing procedures, drawings, calculations, analyses, specifications). | ||
Development of the FPP is informed by the guidance provided in National Fire Protection Association (NFPA) 801, Standard for Fire Protection for Facilities Handling Radioactive Materials (NFPA,2014). The structure and content of the FPP are based on the precepts of 10CFR50.48(a) and NFPA801. The FPP ensures, through the application of the defense-in-depth concept, that a fire will not prevent the performance of necessary safety-related functions and that radioactive releases to the environment, in the event of fire, will be minimized. | |||
9a2.3.2 DESIGN BASES The concept of defense-in-depth is fundamental to the FPP. Fire protection defense-in-depth for the SHINE facility is defined as follows: | |||
.2. | Prevent fires from starting, including limiting combustible materials; Detect, control, and extinguish those fires that do occur to limit consequences; and Provide protection for safety-related structures, systems, and components(SSCs) so that a continuing fire will not prevent the safe shutdown of the irradiation units or cause an uncontrolled release of radioactive material to the environment. | ||
The FPP is developed and implemented to accomplish these criteria. | |||
9a2.3.3 FIRE HAZARD ANALYSIS The foundation of the facility fire protection design is the FHA. The FHA establishes and describes individual facility fire areas, which are unique areas separated by fire-rated construction or administrative controls to prevent the spread of fire between adjacent fire areas. | |||
.3.1 | Chapter 9 - Auxiliary Systems Fire Protection Systems and Programs SHINE Medical Technologies 9a2.3-2 Rev. 1 The FHA is performed to determine the hazard posed by operations and contents resident to the fire area of concern. This analysis identifies the level of fire protection needed to provide the desired confinement/control of postulated fires. The analysis demonstrates the adequacy of protection provided, and, if necessary, the need for additional protection. | ||
The primary objectives of the FHA are: | |||
Establish or identify fire area boundaries, Identify fire hazards within the analyzed area, Determine worst case fire effects on safe shutdown capability of the irradiation units(IUs) and the potential for uncontrolled release of radioactive materials, and Evaluate the adequacy of fire protective features provided. | |||
The FHA is maintained in accordance with the FPP for identified fire areas and facility changes. | |||
9a2.3.4 SAFE SHUTDOWN ANALYSIS The FPP includes performance of a safe shutdown analysis to demonstrate a means of safe shutdown of the SHINE IUs to ensure they can be placed and maintained in a safe and stable condition following a severe fire in any facility fire area. The analysis also considers the effect of severe fires on safety-related equipment required to prevent uncontrolled releases of radioactive material. A deterministic evaluation is conducted on a fire area by fire area basis to ascertain potential damage and assess the effectiveness of the provided protection. | |||
The fire safe shutdown analysis identifies the means by which safe shutdown of the IUs is accomplished and uncontrolled release of radioactive material is prevented for a fire in each facility fire area. Conduct of the safe shutdown analysis is discussed in detail in implementing procedures and reports. Analysis of safe shutdown and prevention of uncontrolled release of radioactive material for the facility is generally conducted through conduct of the following types of analyses: | |||
Development of performance goals and analysis methodology Selection of credited equipment and systems Performance of cable selection and circuit analysis Performance of functional analysis Development of necessary safe shutdown implementing procedures 9a2.3.5 ADMINISTRATIVE CONTROLS Administrative controls and procedures are established by the FPP to ensure satisfaction of the program goals and maintenance of a fire safe workplace. These procedures ensure policies and procedures are in place to minimize the possibility of fire and to provide equipment and systems necessary to mitigate the effects of fires that do occur. Each of the fire-related procedures is designed to strengthen the defense-in-depth approach to fire protection. | |||
9a2.3.6 REGULATORY AND CODE REQUIREMENTS SHINE fire protection systems are designed to comply with the applicable portions of the nationally recognized codes and standards identified below. Adherence to these codes and standards ensures that the facility fire protection features and systems are available to perform | |||
.3. | |||
Chapter 9 - Auxiliary Systems Fire Protection Systems and Programs SHINE Medical Technologies 9a2.3-3 Rev. 1 their functions when required. The SHINE facility is designed to meet the following fire protection objectives: | |||
Prevent fire initiation by controlling, separating, and limiting the quantities of combustibles and sources of ignition. | |||
Isolate combustible materials and limit the spread of fire by subdividing the facility into fire areas separated by fire-rated barriers. | |||
Separate redundant safety-related components and associated electrical divisions to ensure the capability to achieve and maintain safe shutdown and prevent uncontrolled releases of radioactive material as a result of fire. | |||
Provide confidence that failure or inadvertent operation of firefighting systems does not significantly impair the safety capability of credited SSCs. | |||
Provide incipient firefighting capability and access for professional firefighters. | |||
Minimize exposure to personnel and releases to the environment of radioactivity or hazardous chemicals as a result of a fire. | |||
The facility fire protection features and systems are classified as nonsafety-related and generally non-seismic. Facility fire protection features and systems are not required to remain functional following a design basis accident or the most severe natural phenomena. | |||
The design, installation, testing, and surveillance of the facility fire protection features and systems are based on applicable guidance from nationally recognized codes and standards. The codes and standards used and the code-of-record is as defined in the FPP and applicable design documentation. | |||
9a2.3.7 FACILITY FIRE PROTECTION SYSTEM DESCRIPTION The facility is subdivided into fire areas that are separated by fire-rated barriers to limit the spread of fire. The fire area boundaries are described and illustrated in the FHA. In each fire area, the facility fire detection and alarm system provides for the detection and alarm of fire conditions. | |||
Facility fire suppression systems and manual firefighting capability provide for the suppression of fires. These systems consist of the following: | |||
Detection systems for early detection and notification of fire; Fixed automatic fire suppression systems; Manual fire suppression systems and equipment, including hydrants, standpipes, hose stations, and portable fire extinguishers; and A fire water supply system including the fire pump, yard main, and interior distribution piping. | |||
The facility FPP and lower tier documentation provide a complete description of the facility fire protection features and systems. | |||
9a2.3.8 RADIOLOGICAL FIRE HAZARDS Fissionable materials in the form of low-enriched uranium metal and uranium oxide are brought into the facility and used to produce target solution. Target solution is an aqueous uranyl sulfate solution which is irradiated to produce molybdenum-99 (Mo-99) and other medical isotopes. | |||
Following irradiation, the target solution is transferred through piping and tanks for chemical processing in the radioisotope production facility (RPF) to extract Mo-99, other radioisotopes, | |||

These processes present a possibility of radiological release from processes, with fire presenting an energetic source that can drive release. Radiological release due to fire is typically associated with combustion of radiologically contaminated ordinary combustible materials or fire damage to confinement systems that could allow release of collocated radiological materials. | |||
Uranium oxide and uranium metal are received and stored in the uranium receipt and storage system(URSS) room. Storage of the uranium metal and uranium oxide is in metal storage canisters. Canisters are stored on metal storage racks to ensure a safe configuration of the stored materials. Uranium metal is received in sufficiently massive configurations that it is not pyrophoric. | |||
TSPS and URSS rooms are protected with automatic fire detection and provided with | The TSPS and URSS rooms are protected with automatic fire detection and provided with appropriate portable fire extinguishers for incipient stage fire suppression. Combustible loading in these rooms is maintained low to prevent fire. Fire response using water-based extinguishants is prohibited; elevated floors of the URSS and TSPS fire area are provided to prevent flooding of these rooms. | ||
Irradiation is performed in the irradiation facility (IF). Chemical processing, to extract medical isotopes from the target solution, is performed in the RPF. The irradiation and chemical processing of radiological materials is discussed in detail in Chapter4. | |||
Once target solution is introduced to the irradiation process, it is contained in pipes and tanks. | |||
These pipes and tanks are located in the IU cells, hot cells, tank vaults, and pipe trenches throughout the IF and RPF. The IU cells, hot cells, tank vaults, and pipe trench structures are constructed of massive steel and concrete barriers to provide radiation shielding. The monolithic construction of these structures provides significant fire separation from the general areas of the IF and RPF. This construction provides protection to the pipes and tanks containing radiological materials. Combustible loading in the spaces within the IU cells, hot cells, tank vaults, and pipe trenches is maintained very low. Combustible materials in these spaces are limited to cable and equipment. Combustible loading in the IF and RPF general areas is maintained low to present a minimal potential for fire. The IF and RPF general areas are equipped with automatic fire detection and provided with portable fire extinguishers to provide incipient fire suppression capability. | |||
Filters contained in the facility ventilation systems that may contain fission products are replaced on a regular basis. Filters are contained in non-combustible ductwork. Areas of the radiologically controlled area(RCA) containing filters are protected with automatic fire detection and portable fire extinguishers. Combustible loading is maintained low in these areas. | |||
carbon guard beds located in the process vessel vent system (PVVS) are equipped with | The carbon guard beds located in the process vessel vent system (PVVS) are equipped with temperature detection. The guard beds are isolated upon indication of an unacceptable increase in temperature. The carbon delay beds are monitored with in-bed temperature detection and carbon monoxide detectors at the outlet of each carbon delay bed group. The carbon delay beds are equipped with a nitrogen purge line that may be used to extinguish hot spots if detected. | ||
Three facility systems are provided to mitigate hydrogen generation due to radiolysis. These systems are the TSV off-gas system (TOGS), PVVS, and nitrogen purge system (N2PS). | |||
Chapter 9 - Auxiliary Systems Fire Protection Systems and Programs SHINE Medical Technologies 9a2.3-5 Rev. 1 TOGS is the subcritical assembly system (SCAS) gas management system. The TOGS sweeps radiolysis and fission product gases from the TSV during irradiation and from the TSV dump tank during cool down. The TOGS is located in the TOGS cell of each IU. During target solution irradiation, iodine and noble gases are formed by fission and decay, and hydrogen and oxygen are formed by radiolysis. The hydrogen concentration in the TSV headspace is normally maintained below lower flammability limit (LFL) by using air as a sweep gas. The TOGS system is described in detail in Section4a2.8. | |||
PVVS provides ventilation for the tanks in the RPF. The system dilutes radiolytic hydrogen | The PVVS provides ventilation for the tanks in the RPF. The system dilutes radiolytic hydrogen generated in RPF tanks and captures or delays radiological off-gas prior to release out the stack. | ||
Blowers at the discharge of the system develop a slight vacuum to pull air across the headspace of each tank. The flow rates across each tank are balanced such that radiolytic hydrogen generated in each tank is diluted below the hydrogen LFL. The PVVS is described in detail in Section9b.6. | |||
N2PS provides back-up sweep gas flow in the form of stored, pressurized nitrogen gas. | The N2PS provides back-up sweep gas flow in the form of stored, pressurized nitrogen gas. | ||
Upon a loss of power, or the loss sweep gas flow in an IU as determined by the TSV reactivity protection system (TRPS), solenoid valves on the N2PS discharge manifold will fail open releasing nitrogen to the IU cell supply header. Upon a loss of sweep gas flow in an IU, nitrogen gas supply solenoid isolation valves for that cell will be deenergized to the open position, releasing nitrogen gas to the TSV dump tank in that cell. A flow switch will give indication that nitrogen sweep gas is flowing to the IU cell distribution system. The flow rates into each TSV dump tank are balanced such that the radiolytic hydrogen generated in each tank is diluted to acceptable concentrations. The sweep gas flows through the TSV dump tank, the TSV, and TOGS equipment and piping and is discharged into the PVVS. | |||
Upon a loss of power or loss of sweep gas flow through PVVS as determined by the engineered safety features actuation system (ESFAS), normal radiological ventilation zone2 (RVZ2) flow is isolated and nitrogen purge gas is directed to the RPF distribution header. A flow switch provides indication that nitrogen sweep gas is flowing to the RPF distribution system. The flow rates across each tank are balanced such that the radiolytic hydrogen generated in each tank is diluted below the LFL. The nitrogen gas flows through the existing PVVS piping and into the PVVS. | |||

9a2.7.1 TRITIUM PURIFICATION SYSTEM The tritium purification system (TPS) is a tritium-deuterium isotope separation system designed to receive mixed tritium-deuterium gas from operating neutron driver assembly system (NDAS) units and provide high purity tritium and deuterium streams to each operating NDAS unit. The TPS components are located in the TPS room. The TPS consists of three trains which service the eight NDAS units. | |||

The transfer lines travel through subgrade penetrations between the TPS room and each NDAS. Monitoring capability is provided for the interface lines to detect potential tritium leaks. The TPS-NDAS interface lines are protected from mechanical impact between the TPS gloveboxes and subgrade penetrations. | ||
.7.1.1.2 | 9a2.7.1.1.3 TPS Gloveboxes The TPS gloveboxes are confinement gloveboxes that enclose the isotope separation process equipment. The TPS gloveboxes are maintained at negative pressure relative to the TPS room and have a helium atmosphere. The glovebox atmospheres are cleaned by the secondary enclosure cleanup (SEC) to maintain low levels of tritium contamination and oxygen. A detailed physical description of the TPS glovebox is provided in Subsection9a2.7.1.4. | ||
.7.1.1.3 | 9a2.7.1.1.4 Secondary Enclosure Cleanup Subsystem The SEC removes tritium from the helium atmosphere of the TPS gloveboxes. The SEC removes tritium in glovebox environments from both chronic sources (leakage and permeation) and accidental releases. The SEC also maintains low levels of oxygen and moisture in the glovebox atmospheres. The SEC uses a combination of cleanup beds to capture elemental tritium and tritiated water. The cleanup beds are periodically replaced to ensure proper SEC function. The SEC recirculates the TPS glovebox atmospheres. | ||

Process streams are evacuated through an arrangement of tritium capture beds, and the waste streams are monitored for tritium concentration before exhausting to the facility ventilation. | ||
9a2.7.1.1.6 NDAS Secondary Enclosure Cleanup The NDAS SEC removes tritium from the atmosphere of the NDAS secondary enclosures. The NDAS SEC removes tritium in NDAS secondary enclosure environments from chronic sources (leakage and permeation) that occur during NDAS operation. | |||
9a2.7.1.1.7 Tritium Purification System Room The TPS room houses the TPS gloveboxes, VAC/ITS equipment, NDAS secondary enclosure cleanup equipment, TPS fume hoods, SEC equipment, and supporting control and process equipment. | |||
9a2.7.1.2 Design Bases The TPS maintains the integrity of the TPS confinement boundary by preventing leakage to the IF from the TPS gloveboxes, SEC process equipment, and TPS-NDAS interface lines, which could result in potential off-site exposures to individual members of the public or occupational dose exposures to individual workers in excess of prescribed dose criteria, which are described in Section11.1. TPS isolation functions are actuated by the engineered safety features actuation system (ESFAS) as described in Section7.5. | |||

Primary confinement isolation functions are actuated by the target solution vessel (TSV) reactivity protection system (TRPS), as described in Section7.4. | ||
SHINE design criteria applicable to the TPS are described in Section3.1. | |||
9a2.7.1.3 Tritium Purification Process Sequence The TPS isotope separation process begins with a pair of liquid-nitrogen cooled cryopumps that draw in mixed tritium-deuterium target chamber exhaust gas from NDAS units that interface with the TPS respective train. A guard bed in front of the two cryopumps removes moisture impurity before it reaches the cryopumps. The cryopumps are cycled to either capture gas from operating NDAS units or heated to deliver gas to a permeator that provides additional impurity removal of the gas stream. | |||

As the gas moves through the permeator, impurities are prevented from passing through the permeator wall while hydrogen isotopes permeate across to the permeator outlet, resulting in high purity hydrogen | ||
to the isotope separation process. Impurities that build up on the permeator are periodically | Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9a2.7-3 Rev. 2 isotopes at the permeator outlet. The permeator outlet is connected to a second set of two liquid-nitrogen cooled cryopumps that cycle between recovering gas from the permeator and delivering gas to the isotope separation process. Impurities that build up on the permeator are periodically evacuated to maintain proper permeator functionality. | ||
After passing through the permeator, deuterium and tritium isotopes are separated through the Thermal Cycling Adsorption Process (TCAP). The TCAP separates deuterium and tritium through the thermal cycling of a palladium-based column and a molecular sieve column. By thermally cycling the TCAP columns, pure tritium gas is collected at one end of the palladium-based column and pure deuterium is collected at one end of the molecular sieve column. Tritium is then drawn from the end of the palladium-based column and deuterium is drawn from the molecular sieve column. | |||
TCAP is a batch process. To receive and deliver a continuous supply of gas to and from operating NDAS units, an arrangement of feed, product, and raffinate tanks is used together with the separation columns. The feed tank is used to supply mixed tritium and deuterium gas to the TCAP separation columns, which separates the two isotopes and fills the product and raffinate tank. The product tank is used to supply the tritium target gas interface line, which is used to supply target gas to each operating NDAS. In-process tritium instrumentation monitors the separation process to ensure proper TCAP functionality, The isotope separation equipment is confined inside the TPS gloveboxes. The TPS gloveboxes provide a tritium confinement boundary along with isolation valves to ensure excessive tritium releases to the facility and environment do not occur. The TPS gloveboxes also provide confinement in the event of a breach in the TPS process equipment. | |||
To receive new tritium gas or store process tritium before entering maintenance, the TPS contains tritium storage vessels, such as depleted uranium beds. The uranium storage beds allow tritium to be safely stored during maintenance operations on the TPS. A supply volume provides the ability to add measured amounts of tritium to the TPS from either the storage bed or an external source. | |||
A VAC/ITS contains the support equipment necessary to evacuate TPS process lines to support normal operations and to prepare for TPS maintenance. The VAC/ITS are capable of removing both elemental and oxide forms of tritium. TPS waste streams are monitored for tritium concentration before exhausting to the facility ventilation. The NDAS may be evacuated before some maintenance operations, so the NDAS evacuation waste streams may also be treated in the VAC/ITS to remove tritium before exhausting the NDAS waste stream to the facility ventilation. | |||
Deuterium source gas is supplied to the NDAS for the NDAS ion source from an external bottle supply. Deuterium source gas exhaust is exhausted to the facility ventilation. NDAS target chamber exhaust consisting of tritium and deuterium gas is returned to the TPS for isotope separation. The NDAS may also be flushed with air and evacuated down to vacuum through the VAC/ITS, which may remove trace tritium before the waste stream enters the facility ventilation. | |||

The gloveboxes have a stainless steel shell with gloveports and windows on both sides for operator access to equipment. The glovebox has feedthrough connections to allow process tubing, electrical power, and instrumentation lines to pass through the gloveboxes to the TPS process equipment.

.7.1.5 | 9a2.7.1.5 Glovebox Atmosphere Treatment Small amounts of tritium are released into the gloveboxes during normal operation, so the gloveboxes each have a cleanup system designed to treat the atmosphere to minimize the tritium concentration.

SEC involves molecular sieve beds and a hydride bed to remove most elemental and | The SEC involves molecular sieve beds and a hydride bed to remove most elemental and oxidized tritium. The cleanup beds are replaced as required over the course of operations. | ||
.7.1.6 | 9a2.7.1.6 Radiological Protection The processes associated with the TPS are performed within gloveboxes to minimize the exposure of individuals to tritium. The TPS equipment outside the gloveboxes that can contain tritium is normally under partial vacuum. Monitors are located near tritium tubing and at glovebox workstations to identify tritium leaks. The TPS is designed to maintain occupational exposures to tritium to within as low as reasonably achievable (ALARA) program goals. Releases of tritium to the facility or environment are within 10 CFR 20 limits. | ||
Process lines that penetrate the glovebox confinement boundaries have isolation valves that close on high tritium alarm in the glovebox. In the event of a tritium release, the glovebox may be isolated from the rest of the TPS process and IF through actuation of the isolation valves. | |||
Isolation valves are also located on process lines at the interface between the TPS and NDAS units that can be closed to support confinement of an irradiation unit (IU) cell. | |||

NSC shield walls are made from approximately 24-inch (61 centimeter) thick concrete walls reinforcing carbon steel bars. Additional local shielding, such as water or polycarbonate | Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9a2.7-6 Rev. 2 Commissioning, maintenance, and disposal activities associated with the NDAS and performed in the NSC are summarized below. | ||
Commissioning An NDAS may be tested in the NSC prior to installation in an IU cell. The NDAS sub-assemblies will be staged, mounted to the supporting pads in the NSC, and assembled with the support of the facility crane. The assembled NDAS is connected to service utilities such as electrical, control, cooling water, and supply gases inside and outside the NSC. The commissioning activities to be carried out in the NSC may include establishing vacuum, helium leak rate testing, filling the pressure vessel with sulfur hexafluoride (SF6) gas, and beam performance testing. | |||
.7.2.4 | Maintenance If portions of an NDAS require maintenance or replacement, it may be moved from an IU cell to the NSC. The NDAS is lifted by the IF bridge crane and transferred to the NSC where work can be performed. | ||
Disposal The NSC may also be used to disassemble an NDAS into smaller parts that can fit more easily into containers before sending to an appropriate waste repository. | |||
9a2.7.2.3 Radiological Protection Gamma radiation monitoring of the NSC is provided to allow for safe operation and interlocking of activities in the NSC. The NSC has a directed airflow system to manage residual tritium contamination of NDAS components. This airflow system maintains the capability to interface with the facility heating, ventilation, and air conditioning (HVAC) through radiological ventilation zone 2 exhaust (RVZ2e). A passive tritium sample collector at the interface to RVZ2e provides a record of tritium content entering RVZ2e from the NSC. The NSC provides a real-time tritium monitor at the interface to the RVZ2e to measure real-time tritium content in exhaust gas from NDAS testing sent to RVZ2e. | |||
The NSC shield walls are made from approximately 24-inch (61 centimeter) thick concrete walls with reinforcing carbon steel bars. Additional local shielding, such as water or polycarbonate blocks, may also be installed during testing in the NSC. Implementation of local shielding in the pit, and around an installed NDAS as necessary, provides radiation shielding during NDAS testing. This local shielding functions in conjunction with the shielding provided by the NSC shield walls and door to maintain occupational exposures to neutron and gamma radiation to within ALARA program goals. Table11.1-4 provides radiation areas at the main production facility, and includes dose rates to the IF general area during accelerator testing in the NSC. Calculated dose rates during accelerator operation in the NSC are approximately 8 mrem/hr outside the NSC walls. The annual average neutron flux to the NSC surrounding soil is expected to be less than 100 n/cm2-s. | |||
9a2.7.2.4 Instrumentation and Controls The NSC provides instrumentation and controls to perform testing of an NDAS to verify proper operation before returning to service. Interlocks for safe testing of the NDAS, such as preventing operation of the NDAS while the service cell door is open are provided. A radiation interlock button located inside the NSC prevents or shuts down operation of the NDAS when actuated by personnel in the NSC. | |||

Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9b.1-1 Rev. 1 9b RADIOISOTOPE PRODUCTION FACILITY AUXILIARY SYSTEMS 9b.1 HEATING, VENTILATION, AND AIR CONDITIONING SYSTEMS The heating, ventilation, and air conditioning (HVAC) systems for the main production facility are common to the irradiation facility (IF) and the radioisotope production facility (RPF). The main production facility HVAC systems are described in Section9a2.1. | |||
Chapter 9 - Auxiliary Systems Handling and Storage of Target Solution SHINE Medical Technologies 9b.2-1 Rev. 1 9b.2 HANDLING AND STORAGE OF TARGET SOLUTION 9b.2.1 TARGET SOLUTION LIFECYCLE This section addresses the lifecycle of the target solution from the time that it enters the jurisdiction of the SHINE facility until it is released from such jurisdiction. | |||
Target solution is a low-enriched, uranyl sulfate solution that is prepared by converting solid uranium oxide into the uranyl sulfate solution using the target solution preparation system (TSPS). Low enriched uranium (LEU) is received by the uranium receipt and storage system (URSS) as either uranium metal or uranium oxide. If metal is received, the URSS converts the metal to uranium oxide, as described in Subsection4b.4.2. After preparation, the target solution is held in the target solution preparation tank until it is transferred to the target solution staging system (TSSS) and loaded into the target solution vessel (TSV) from the TSSS for an irradiation cycle. After irradiation is complete, the irradiated target solution is transferred to the molybdenum extraction and purification system (MEPS) where molybdenum is separated from the target. | |||
Following processing in MEPS, the target solution may be delivered to the TSSS for storage or another irradiation cycle, to the radioactive liquid waste storage (RLWS) system for disposal, or to the iodine and xenon purification and packaging (IXP) system for separation of iodine and xenon isotopes as products. At the end of its lifecycle as target solution, the uranyl sulfate solution is transferred to the RLWS. In the RLWS, the uranyl sulfate solution is blended with other waste streams and held in storage until it is ready to be solidified by the radioactive liquid waste immobilization (RLWI) system. Solidified wastes are transferred to the material staging building for preparation for shipment off-site. | |||
The chemical properties of the target solution are described in Subsection4a2.2.1. | |||
2. | Detailed descriptions of the processes involving irradiated and unirradiated special nuclear material (SNM) are provided in Subsection4b.4.1 and Subsection4b.4.2, respectively. | ||
2. | Equipment, application of administrative controls, and the design features involved in the SNM lifecycle are included in this section. | ||
Section12.8 provides a discussion of the physical security of the SNM. Section4b.2 provides a discussion of the shielding requirements associated with irradiated target solution. Section5a2.2 provides a description of the primary closed loop cooling system(PCLS), which is used to remove heat from the TSV and neutron multiplier during irradiation of the target solution. | |||
Chapter13 provides the accident analysis accident analysis of the SHINE facility, including those scenarios related to the storage and handling of target solution. Detailed discussions of radiological considerations related to the handling and storage of target solution are provided in Section11.1. | |||
2 | 9b.2.2 RECEIPT AND STORAGE OF UNIRRADIATED SNM The URSS receives, handles, and stores unirradiated uranium. The URSS facilitates the sampling of received SNM and converts uranium metal to uranium oxide prior to its use in TSPS. | ||
Uranium is stored in canisters placed on racks designed for criticality safety. Subsection6b.3.2 provides information on criticality safety controls for receipt and storage of uranium. | |||
A detailed description of the URSS is provided in Subsection4b.4.2.1. | |||
Chapter 9 - Auxiliary Systems Handling and Storage of Target Solution SHINE Medical Technologies 9b.2-2 Rev. 1 9b.2.3 TARGET SOLUTION PREPARATION The TSPS converts uranium oxide into a uranyl sulfate solution for use as a target solution batch or as makeup solution. Uranium is transferred from the URSS and imported into the TSPS glovebox for dispensation into the dissolution tanks. After conversion to uranyl sulfate in the dissolution tank, the uranium solution is pumped to the target solution preparation tank for storage until it is needed for an irradiation cycle or as makeup solution. | |||
A detailed description of the TSPS is provided in Subsection4b.4.2.2. | |||
9b.2.4 TARGET SOLUTION STAGING SYSTEM Target solution batches prepared for irradiation are transferred from the TSPS to the TSSS. The TSSS consists of target solution hold tanks and target solution storage tanks. Target solution hold tanks stage the target solution for transfer into the primary system boundary (PSB). Target solution storage tanks provide additional storage capacity for the facility. Tanks in the TSSS can receive target solution discharged from processes in the hot cells. The target solution may be sampled from each tank. | |||
A detailed description of the TSSS is provided in Subsection4b.4.1.1. | |||
9b.2.5 VACUUM TRANSFER SYSTEM The vacuum transfer system (VTS) provides the transport of radioactive liquids, including target solution, throughout the radioisotope production facility (RPF). The VTS operates by applying vacuum to an intermediary lift tank or directly to a destination tank. The VTS also provides vacuum service to RPF systems. | |||
9b.2.5.1 Design Bases The VTS is designed to: | |||
Prevent inadvertent criticality in accordance with the criticality safety evaluation. | |||
Relieve the system to atmospheric pressure upon actuation of the engineered safety features actuation system (ESFAS) to terminate transfers of target solution. | |||
9b.2.5.2 | |||
2.5 | |||
===System Description=== | |||
The VTS consists of vacuum pumps, a knockout pot, vacuum lift tanks, and associated piping components and instrumentation. Process piping and pipe components are designed to meet the requirements of ASME B31.3, Process Piping (ASME,2013). | |||
VTS transfers liquid by one of the two following distinct methods: | |||
The first method moves liquid in batches via small volume tanks. These tanks are collectively named lift tanks. In the VTS, a vacuum is drawn on the knockout pot by a set of vacuum pumps, which discharge to the process vessel vent system (PVVS) for off-gas treatment. Solution transfers occur by aligning a vacuum lift tank with the knockout pot. | |||
Vacuum is applied to the lift tank, and solution flows from the source tank. Once the vacuum lift tank level setpoint is reached, the lift tank is isolated from the knockout pot | |||
Chapter 9 - Auxiliary Systems Handling and Storage of Target Solution SHINE Medical Technologies 9b.2-3 Rev. 1 and the lift tank is vented to atmosphere. Once pressure is equalized, the solution may be drained, pumped from the lift tank, or transferred to a second stage of lift tanks for additional elevation gain. Liquid transfers using vacuum lift tanks in the RPF are identified in Table9b.2-1. | |||
The second method facilitates solution transfers without using a vacuum lift tank. Vacuum from the knockout pot is applied directly to the selected destination tank, and valves in the pathway between the source tank and destination tank are aligned to allow flow. This method is typical for transfers in the RLWS system, the RLWI system, and between laboratory scale processes that are part of the isotope separation process. Direct liquid transfers between tanks facilitated by VTS are identified in Table9b.2-2. | |||
Two separate vacuum headers are provided based on the liquid being transferred. Tanks designed to contain target solution are provided with vacuum from a separate header than tanks with concentration controls or other tanks or services that are not intended to contain fissile material. The headers are air gapped at the knockout pot as shown in Figure9b.2-1. | |||
2. | The VTS provides an interface for sampling of solution in the target solution hold tanks, target solution storage tanks, RLWS system tanks, and the radioactive drain system (RDS). | ||
The VTS is the only system used to transport SNM between the RPF and IF. A description of the process used to fill the TSV is provided in Subsection4a2.6.1. The VTS is one of the systems used to transport solutions of SNM or byproduct material in the RPF. The other systems used to transport solutions containing SNM or byproduct material in the RPF are TSPS, MEPS, IXP, and the RLWI system, which use pumps to provide the motive force to transport the solutions. | |||
Table9b.2-3 identifies the systems which interface with the VTS. | |||
Figure9b.2-1 provides a process flow diagram of the VTS. | |||
9b.2.5.3 Instrumentation and Controls Temperature of solution in the source tank is monitored prior to a transfer to ensure that the transfer does not induce the solution to flash in the pipe. Level of each vacuum lift tank is also monitored to allow the process integrated control system (PICS) to control each transfer. | |||
Automatic flow shut-off valves and liquid detection instruments are provided in the VTS to prevent solution from entering the knockout pot. On detection of liquid by these instruments, ESFAS actuates valves that act as vacuum breakers on the knockout pot and trips the breakers on the vacuum pumps, terminating solution transfers. The knockout pot drains to favorable geometry tanks in the RLWS system in the event of high-level alarm. ESFAS also trips the vacuum breaking valves and pump on detection of high radiation in radiological ventilation zone1 (RVZ1) or on level detection in the RDS. A detailed description of the ESFAS is provided in Section7.5. | |||
9b.2.5.4 Safety Analysis The VTS is a safety-related system. The VTS structural framework and pipe supports are designed to withstand design basis seismic events. The VTS is classified as Seismic Category I. | |||

9b.2.6 RADIOACTIVE LIQUID WASTE STORAGE Liquid wastes from the isotope production processes may contain SNM. These liquids are drained from the hot cells to the first favorable geometry uranium waste tank in the RLWS system. Once the liquid waste is verified to be below administrative limits, it is transferred to the second uranium waste tank where it is sampled again prior to sending to the liquid waste blending tanks for additional storage time. Target solution batches are disposed of through the RLWS system. Once a batch is designated for disposal, it is transferred to the RLWS system to be blended with other wastes. | |||
A detailed description of the RLWS system is provided in Subsection9b.7.4. | |||
9b.2.7 RADIOACTIVE LIQUID WASTE IMMOBILIZATION Liquid wastes in the RLWS system are solidified by the RLWI system. Liquid wastes in the RLWS system may contain SNM. Solutions are transferred to the RLWI system by the VTS from the RLWS system. In the RLWI system, solution may be [ | |||

Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-1 Rev. 2 9b.6 COVER GAS CONTROL IN THE RADIOISOTOPE PRODUCTION FACILITY This section discusses radiolytic gas management systems located in the radioisotope production facility (RPF) that manage radioactive gases associated with SHINE facility processes. | |||
9b.6.1 PROCESS VESSEL VENT SYSTEM The process vessel vent system (PVVS) collects and treats the off-gases from processes in the main production facility. The PVVS collects off-gases from each RPF tank containing irradiated solutions, from the vacuum transfer system (VTS) vacuum pump discharge, and periodically from the target solution vessel (TSV) off-gas system (TOGS). The PVVS consists of acid adsorbers, carbon filters, high-efficiency particulate air (HEPA) filters, condensers, reheaters, carbon beds, and blowers which are employed to vent treated gases out of the radiologically controlled area (RCA). A description of system interfaces is provided in Table9b.6-1. | |||
9b.6.1.1 Design Bases The design bases of the PVVS include: | |||
Mitigate radiolytic hydrogen generation in the headspace of RPF tanks and vessels; Capture radioiodine from the off-gas stream; Delay the release of radioactive noble gases in gaseous effluents to the environment; Filter radioactive particulates from the gaseous effluents; Maintain RPF tanks and vessels at a negative pressure; Accept VTS vacuum pump discharge; Accept TOGS pressure relief discharge; Accept purges of TOGS, resulting from either a loss of TOGS capability to mitigate radiolytic hydrogen generation or maintenance requirements; Accept any sweep gases from TOGS used to purge gas analyzer instrumentation; Condition collected off-gas to improve reliability and performance of filtration equipment; and Discharge off-gases to the facility stack. | |||
9b.6.1.2 | |||
===System Description=== | |||
The PVVS provides radiolytic hydrogen mitigation capability for the RPF by ventilating the process tanks and vessels. The PVVS also accepts gases discharged from VTS and TOGS. | |||
Flows from VTS and TOGS include vacuum pump discharge, sweep gas from gas analyzer instruments, nitrogen purges, and pressure relief. PVVS blowers upstream of the stack induce flow through the ventilation system. Flow rate requirements for PVVS are constant for nominal ventilation in the RPF but increase when tanks are sparged for mixing, when VTS is operating, or during TOGS transients such as a purge during fill or maintenance, or pressure relief. PVVS equipment is designed for the maximum off-gas flow rate that could require processing at any one time. | |||
The off-gases are processed to remove or delay iodine, noble gases, and radioactive particulates prior to gas being discharged to the facility stack. PVVS blower placement results in the system being maintained at a negative pressure relative to ventilation zone 2. Intakes within ventilation zone 2 are the nominal air source for PVVS. Air flows from the intake, across | |||
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-2 Rev. 2 the tank headspace, to the PVVS conditioning and filtration equipment. Gases pass through condensers, cooled with process chilled water, to remove excess heat and reduce absolute humidity of the off-gas. | |||
Condensate is collected in the PVVS condensate tank within the PVVS hot cell, located within the supercell. Condensate may be returned to the target solution staging system (TSSS) tanks as makeup water or to the radioactive liquid waste storage (RLWS) system for waste processing. An in-line heater, the PVVS reheater, downstream of the condenser heats the off-gas back to ambient temperature to reduce the relative humidity. The off-gas then flows through acid adsorber beds, HEPA filters, and the guard beds to neutralize entrained acid droplets or gases, filter particulates, and capture iodine. The gas flows from the hot cell to a below-grade, shielded vault, passing through a series of delay beds packed with carbon to delay the release of fission product noble gases such as xenon and krypton. The eight delay beds are organized into three groups as shown in Figure9b.6-1. Group 1 includes Delay Beds 1 and 2. Group2 includes Delay Beds 3, 4, and 5. Group 3 includes Delay Beds 6, 7, and 8. A final set of HEPA filters removes any entrained carbon fines upstream of the blowers, and the treated gases are discharged to the facility stack. | |||
In the event PVVS flow drops below the minimum flow rate of 5.0standard cubic feet per minute, the engineered safety features actuation system (ESFAS) automatically initiates an RPF Nitrogen Purge. This results in the nitrogen purge system (N2PS) providing nitrogen flow to the RPF tanks to mitigate hydrogen generation. Upon actuation of the N2PS, the RPF header valves actuate open, the isolation valves at the PVVS north and south header valves actuate closed, and the PVVS isolation valve at the radioactive liquid waste immobilization (RLWI) interface actuates closed to prevent nitrogen backflow. During the nitrogen purge, the PVVS equipment and piping continues to provide the flow path for the off-gas through the RPF. | |||
Safety-related bypasses are provided around filtration equipment in the hot cell that could contribute to a blocked pathway and an alternate, safety-related exhaust point to the roof is actuated open. The branch to the alternate release point is upstream of the PVVS blowers. | |||
Fire protection is provided for the guard beds and delay beds. Temperature instrumentation and carbon monoxide detection are used to monitor for oxidation. The beds may be isolated or purged with nitrogen to smother the reaction. Additionally, operators can attempt to increase the system flow rate to increase convective cooling. The ESFAS automatically isolates affected delay bed groups when carbon monoxide concentrations in the effluent gas exceed 50 ppm. | |||
Principal components of the PVVS are identified in Table9b.6-2. | |||
A process flow diagram of the PVVS is provided in Figure9b.6-1. | |||
9b.6.1.3 Operational Analysis and Safety Function The PVVS provides confinement of fission products to prevent release of radioactive material. | |||
The PVVS maintains hydrogen concentrations below the lower flammability limit(LFL) to preclude a hydrogen deflagration or detonation, as discussed in Subsection9b.6.1.3.1. The PVVS passively reduces the concentration of radionuclides in the gaseous effluent to the facility stack, including during postulated transients, as discussed in Subsection9b.6.1.3.2. | |||
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-3 Rev. 2 In addition to the above: | |||
Safety-related components in the PVVS remain functional during normal conditions, and during and following design basis events. | |||
Valves in PVVS fail to their designated safe position on loss of power. | |||
Redundant isolation capabilities are provided at confinement boundaries. | |||
Redundant isolation is provided for safety-related actuations. | |||
An open flow path through PVVS remains available during normal conditions, and during and following design basis events. | |||
PVVS components installed over, attached to, or adjacent to safety-related equipment are designed so as not to fail in such a way that is detrimental to the operation of safety-related equipment. | |||
9b.6.1.3.1 Hydrogen Mitigation Hydrogen is generated by radiolysis in the target solution and the byproduct solutions contained in the process tanks of the RPF, excluding the target solution preparation system (TSPS). Build-up of the hydrogen could result in a detonation or deflagration if the concentration exceeds the LFL. PVVS ventilates the RPF tanks to prevent build-up of hydrogen above LFL. | |||
In the event of failure of the PVVS discharge blowers, the PVVS filtration equipment continues to process the sweep gas provided from N2PS through the tanks throughout the RPF. The quantity of sweep gas supplied is sufficient to maintain hydrogen concentration below the LFL. | |||
Under normal operation, the required quantity of sweep gas is induced into the process tanks by the suction from the PVVS blowers. In the event of failure of the PVVS blowers, the N2PS will provide the sweep gas flow, thereby maintaining the sweep gas component of the total PVVS flow. | |||
9b.6.1.3.2 Iodine and Noble Gas Abatement The systems and processes in the RPF release radioactive isotopes of iodine and noble gases from the target solution and from byproduct solutions. Gases discharged by TOGS from the primary system boundary, which contain noble gases and iodine, are also processed by the PVVS. The off-gas may also contain radioactive particulates such as cesium. HEPA filters are used to remove entrained particulates from the air flow. Carbon filters are used to capture iodine and carbon beds are employed to delay the release of xenon and krypton isotopes. The design ensures that 10 CFR 20 limits are met. | |||
9b.6.1.4 Instrumentation and Control Safety-related PVVS instrumentation has redundant channels and provides output to ESFAS. | |||
Nonsafety-related PVVS instrumentation provides output signals to the process integrated control system (PICS). | |||
Temperature instrumentation is used to monitor the performance of the condensers, heaters, and acid adsorbers as well as the guard beds and delay beds. | |||
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-4 Rev. 2 Redundant gas analyzers monitor the hydrogen concentration upstream of the guard beds. The gas analyzers are used to monitor the operation of the delay beds and to monitor carbon monoxide concentrations in the bed effluent. | |||
6. | Flow instrumentation is used to monitor the flow rate of air from ventilation zone 2 into the RPF tanks and vessels ventilated by PVVS. The PICS alerts operators on low flow. Flow instrumentation is used to monitor the flow rate of air from the RPF tanks and vessels to the condensers. The system is designed to maintain this flow rate above the minimum required to maintain hydrogen levels below the LFL. | ||
Pressure instrumentation is provided to monitor performance of the HEPA filters. | |||
9b.6.1.5 Radiological Protection and Criticality Control PVVS processes are performed within the production facility biological shield (PFBS) hot cells and below-grade vaults, which supports compliance with the as low as reasonably achievable (ALARA) objectives and 10 CFR 20 dose limits. Section11.1 provides a description of the radiation protection program, and Section4b.2 provides a detailed description of the PFBS. | |||
There are no credible mechanisms by which to create a criticality hazard in the PVVS. As described in Subsection6b.3.1.6, there are no identified criticality safety controls for the PVVS. | |||

This includes limiting conditions for operation, setpoints, design features, and means for accomplishing surveillances. In addition, significant material is also applicable to, and may be used for the bases that are described in the technical specifications. | |||
9b.6.2 NITROGEN PURGE SYSTEM The N2PS provides a backup supply of sweep gas to each irradiation unit (IU) and to all tanks normally ventilated by the PVVS during a loss of normal power or loss of normal sweep gas flow. The off-gas resulting from the nitrogen purge is treated by passive PVVS filtration equipment prior to being discharged to the stack, as discussed in Subsection9b.6.1.2. The nitrogen supply pressure is regulated to overcome the pressure drop through pipe fittings, PVVS filtration components, and the facility stack. The N2PS is safety-related and Seismic Category I. A description of system interfaces is provided in Table9b.6-3. | |||
9b.6.2.1 Design Bases The design bases of the N2PS include: | |||
Ensure safe shutdown by preventing detonations or deflagrations from potential hydrogen accumulation in the IUs and RPF processes during deviations from normal conditions; and Remain functional during and following design basis events. | |||

===System Description=== | |||
N2PS provides back-up sweep gas flow in the form of stored pressurized nitrogen gas. | |||
Downstream pressure is controlled with self-regulating pressure reducing valves with overpressure protection by pressure relief valves. On actuation of the N2PS, nitrogen flows through the irradiation facility (IF) and RPF equipment to ensure the hydrogen concentration is below the LFL. The nitrogen purge flows through the normal PVVS path and filtration equipment, including the delay beds. After exiting the delay beds in PVVS, the nitrogen purge is diverted to a safety-related alternate vent path in case of a downstream blockage. Valves configured to fail open allow the diversion to the alternate vent path. After actuation of the N2PS, the pressurized storage tubes can be refilled by truck deliveries. | |||
6. | A process flow diagram of the N2PS is provided in Figure9b.6-2. | ||
Purge of an IU Upon loss of normal power as determined by the engineered safety features actuation system (ESFAS) and after a delay or upon loss of normal sweep gas flow in the IU as determined by the TSV reactivity protection system (TRPS), solenoid valves on the nitrogen discharge manifold actuate open, releasing nitrogen into the IU cell supply header. Upon loss of sweep gas flow in any IU cell, nitrogen solenoid isolation valves for the given cell actuate open releasing nitrogen purge gas into the TSV dump tank, and valves in the TOGS actuate open to allow the nitrogen purge gas to flow to the PVVS. The nitrogen purge gas flows through the TSV dump tank, TSV, and TOGS equipment before discharging into PVVS. A flow switch provides indication that nitrogen is flowing to the IU cell. A detailed discussion of the IU Cell Nitrogen Purge is provided in Section7.4. | |||
Purge of RPF Equipment Upon loss of normal power or loss of normal sweep gas flow through PVVS, as determined by the ESFAS, solenoid valves on the ventilation zone 2 air supply to PVVS fail closed and isolate the sweep gas air flow to the RPF tanks. At the same time, solenoid valves on the nitrogen discharge manifold actuate open, releasing nitrogen into the RPF distribution piping. The nitrogen flows through the RPF equipment in parallel before discharging into PVVS. A flow switch provides indication that nitrogen is flowing to the RPF distribution piping. | |||
Processes that receive ventilation air from the PVVS during normal conditions are also ventilated by N2PS during deviations from normal operation. In the RPF, the N2PS ventilates tanks in the TSSS, RLWS system, radioactive drain system (RDS), molybdenum extraction and purification system (MEPS), iodine and xenon purification and packaging (IXP) system, and VTS. A detailed discussion of the RPF Nitrogen Purge is provided in Section7.5. | |||
9b.6.2.3 Operational Analysis and Safety Function In the event of a loss of normal power, loss of sweep gas flow through PVVS, or loss of sweep gas flow through any TOGS, the N2PS controls the buildup of hydrogen which is released into the primary system boundary and tanks or other volumes which contain fission products to ensure that the system and confinement boundaries are maintained. | |||
6.2. | |||
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-6 Rev. 2 The N2PS provides back-up sweep gas in the form of stored pressurized nitrogen gas. | |||
Downstream pressure is controlled with self-regulating pressure reducing valves with overpressure protection provided by pressure relief valves. Tanks containing irradiated target solution in the RPF are supplied with a self-regulating pressure reducing valve with overpressure protection provided by a pressure relief valve. TSV dump tanks are supplied with a self-regulating pressure reducing valve. N2PS piping, valves, and in-line components are designed to ASME B31.3, Process Piping (ASME,2013). | |||
The high-pressure nitrogen gas storage is contained in integrally forged pressure vessels (i.e.,high-pressure nitrogen gas tubes) designed to meet the requirements of ASME Boiler and Pressure Vessel Code(BPVC), Section VIII, Rules for Construction of Pressure Vessels (ASME, 2010). The tubes and associated piping, manual isolation valves, high point vents, low point drains, self-regulating pressure reducing valves, relief valves, check valves, and pressure instrumentation for the supply system are located in the N2PS structure, an above-grade reinforced concrete structure adjacent to the main production facility. The N2PS structure and equipment are designed to remain functional during and following a seismic event. Additionally, the N2PS structure is designed to withstand the impact of tornado missiles. | |||
The tubes are manifolded so they will act in unison and have a common remote fill connection to allow refill by tanker truck delivery. One redundant high-pressure nitrogen gas tube provides service in the event of the loss of a tube or failure of the associated valves upstream of the common manifold. Each high-pressure nitrogen gas tube and the downstream piping and equipment is protected from overpressure by relief valves discharging to atmosphere above the roof of the structure, through a nonsafety-related vent path. | |||
The N2PS is sized to provide three days of sweep gas flow to tanks containing irradiated target solution in the RPF during a loss of normal power or a loss sweep gas flow. The N2PS also provides three days of sweep gas flow to each TSV dump tank. | |||
9b.6.2.4 Instrumentation and Control The N2PS includes pressure instrumentation to monitor the function of the self-regulating pressure reducing valves. The nitrogen tube pressure, tube discharge pressures, pressure to the IU cells, and pressure to the RPF tanks are monitored. The pressure instrument output is provided to PICS. | |||
The N2PS includes flow switches on the piping to the IU cells and RPF tanks to provide indication of normal operation when the purge is actuated. The flow switch status is provided to PICS. | |||

The RPF overhead crane employs the use of mechanical stops, electrical-interlocks, and predetermined safe load paths to minimize the movement of loads in proximity to redundant or dual safe shutdown equipment. These safeguards ensures that off-normal load events from loads containing radioactive materials or safety-related SSCs that are beneath, or directly adjacent to a potential travel load path of the RPF overhead crane, could not result in the complete loss of a safe shutdown function or the release of radioactivity in excess of 10 CFR 20 limits. | |||
The RPF overhead crane is designed and constructed following the seismic requirements for an ASME NOG-1, TypeII crane so that it will remain in place with or without a load during a design basis earthquake.

The IF overhead crane is used for lifting, repositioning, and landing operations associated with major components of the subcritical assembly system (SCAS), the primary closed loop cooling system (PCLS), the TOGS, and the tritium purification system (TPS) as well as various planned maintenance activities throughout the IF. | |||
The RPF overhead crane is utilized for lifts including the removal of tank vault, valve pit, and pipe trench plugs, removal of carbon delay bed vault plugs, supercell slave manipulator replacements, and the removal of column waste drums and post cooldown shielding/packaging. The RPF overhead crane is used for various planned maintenance activities. In addition, the crane performs lifting of empty tanks in the RPF, immobilized waste drums and the associated shielding/packaging hardware, and other major components within the RPF. | |||
The IF and RPF overhead cranes are inspected, tested, and maintained in accordance with ASME B30.2 (ASME,2011a). The inspection requirements reduce the probability of a load drop that could result in a release of radioactive materials or damage to essential safe shutdown equipment that could cause unacceptable radiation exposures.

===System Description=== | |||
The RLWI system solidifies blended liquid waste to a form suitable for shipping and disposal. The RLWI system removes selected isotopes, as needed, from the blended liquid waste and then immobilizes the wastes for ultimate disposal. The headspace cover gas in the immobilization feed tank is swept by the PVVS. | |||
The blended liquid waste sources and radionuclide and uranium concentrations are described in Subsection9b.7.4. | |||
The immobilization feed tank is filled from the liquid waste blending tanks on a batch basis by vacuum suction applied to the immobilization feed tank from the vacuum transfer system(VTS). | |||
Positive displacement pumps transfer the contents of the immobilization feed tank [ | |||
]PROP/ECI, and meter the tank contents to a disposable waste drum. | |||
The waste drums are prefilled with measured amounts of dry, powdered solidification agent in accordance with the process control program(PCP). The prefilled drum is transferred into an enclosure for contamination control. The radiological ventilation zone1 exhaust subsystem (RVZ1e) equipment processes air from the enclosure through a high efficiency particulate air (HEPA) and carbon filter before discharging to the facility stack. Transfer of the prefilled waste drum inside the enclosure is by remote handling equipment and positioners. | |||
The liquid waste drum is filled with blended liquid waste and mixed. Subsequent to fill and mixing, the fill and vent ports are disengaged. The drum is then remotely transferred to a curing station where the mixed contents of the waste drum hardens prior to removal from the enclosure. The cured drum is remotely transferred into a shielded cask and transported to the material staging building for further radiological decay, as needed, prior to shipment to a licensed disposal facility. | |||
Remote sampling for waste characterization is performed in the RLWS prior to solidification activities. Radiation measurements are performed on the solidified waste drum prior to shipment in the material staging building to verify it meets shipping dose rate requirements. | |||

The RLWS system collects, stores, blends, conditions, and meters liquid wastes for processing by the RLWI for solidification. Included in the blended liquid wastes is PVVS condensate which can also be recycled through the target solution staging system (TSSS) to minimize waste generation. The RLWS system can also transfer liquid via a normally removed pipe spool to a target solution storage tank for sampling and verification against target solution parameters. The headspace in each RLWS system tank is swept with air by the PVVS or by the nitrogen purge system (N2PS) to remove the potential accumulation of radiolytically generated hydrogen gas. | |||
Laboratory waste is preconditioned and manually processed separately from the RLWS system. | |||
Liquid waste collected, blended, and stored by the RLWS system includes: | |||

===System Description=== | |||
The SRWP system consists of equipment designed and specified to collect and package solid radioactive waste from systems throughout the IF and RPF without limiting the normal operation or availability of the facilities. Solid waste may include dry active waste (DAW), spent ion exchange resin, and filters and filtration media. The SRWP system also inventories materials entering and exiting the facility structure storage bore holes as the supercell imports and exports them. | |||

Separation columns used in the processes contained within the supercell are stored on supercell storage racks for a minimum of 14 days following their use. Following decay on storage racks, columns are transferred to column waste drums imported by the supercell. The column waste drums are exported and transferred to the drum storage bore holes. Following extended decay, column waste drums are removed from the bore holes by the supercell. | |||
Depending on weight, solid waste may need to be transferred to the material staging building using forklifts or other lifting devices. Once in the material staging building, solid wastes may be held for decay. Waste is characterized and staged for shipment in the material staging building. | |||

===System Description=== | |||
The RDS consists of drip pans with drain lines, tank overflow lines, collection tanks and instrumentation to alert operators of system status. The RDS includes drip pans located beneath the extraction and IXP hot cells, favorable geometry tanks, and piping for systems that normally contain high concentration (> 25 gU/l) fissile solution. The RDS also collects overflow from target solution and uranium waste tanks. The RDS consists of two favorable geometry tanks (annular tanks) that collect leakage from postulated sources. The leakage and overflow are connected by piping that is substantially located within the basemat of the RPF as well as in the RPF pipe trench. Gravity provides the motive force between the various drip pans and the RDS tanks. No valves are installed between the potential collection source and the collection tanks. | |||
Table9b.7-4 identifies the systems which interface with the RDS. | |||
Figure9b.7-5 provides a process flow diagram for the RDS. | |||
9b.7.6.3 Operational Analysis and Safety Function The RDS includes two sump tanks, each sized to accept the largest volume of liquid containing SNM that is postulated to leak from a favorable geometry tank. The largest volume of liquid containing SNM postulated to leak into the RDS system is the volume of the largest favorable geometry tank, assuming the tank is filled to the overflow line. The inclusion of two RDS tanks provides operational margin. | |||
The RDS sump tanks are connected to the target solution storage tanks, target solution hold tanks, and uranium liquid waste tanks. Additionally, the sump tanks are connected to drip pans in vaults containing annular tanks, drip pans in valve pits servicing annular tanks, drip pans in the main pipe trench, and drip pans in the extraction and IXP hot cells. Redundant overflows to a common RDS header are provided for each annular tank. The RDS is not used in any normal operating conditions. Instrumentation is provided to alert operators of the presence of liquid in the various drip pans and of liquid level in the RDS sump tanks. If liquid is detected in the drip pans or sump tanks, contingency actions may be performed by using systems other than the RDS. | |||
Contents of the RDS tanks are sampled and transferred by the VTS to the appropriate location. | |||
Characterization of the sample is performed by the quality control and analytical testing laboratories (LABS). | |||
The RDS needs to remain open for drainage of fissile-containing liquids (for criticality safety), | |||
while also not compromising the integrity of the confinement barrier. Fluids are contained within appropriate process piping and vessels, and the system is vented to the PVVS. | |||
Piping that contains potentially-radiological material is routed through shielded pipe chases to limit the exposure of radiation to personnel. The RDS tanks are shielded by a tank vault, which is a part of the PFBS. The PFBS shielding requirements are described in Section4b.2. | |||
RDS operations are performed in accordance with the requirements of the radiation protection program, described in Section11.1. | |||

9b.7.7.2 | |||
===System Description=== | |||
The FPWS provides a potable water supply to the SHINE facility and is connected to the City of Janesville water supply. The boundaries of the FPWS include the components from the City of Janesville water main to the fixtures in each of the buildings on the SHINE facility. The fixtures are part of the facility sanitary drain system (FSDS), described in Subsection9b.7.9. The FPWS ends at the backflow prevention device interfacing with both the facility demineralized water system (FDWS) and facility heating water system (FHWS). The FPWS does not supply water to the facility fire detection and suppression system (FFPS) or any firefighting equipment. | |||
9b.7.7.3 Operational Analysis and Safety Function Potable water is distributed throughout the SHINE facility through a subgrade piping network. | |||
The FPWS site main connects to SHINE facility building mains, which include the main production facility (outside the RCA), the storage building, and the resource building.

9b.7.8 FACILITY NITROGEN HANDLING SYSTEM 9b.7.8.1 Design Bases The facility nitrogen handling system (FNHS) is designed to supply liquid and compressed gaseous nitrogen to systems inside the RCA. The FNHS gaseous piping is designed, constructed, and tested in accordance with the ASME B31.9, Building Services Piping (ASME, 2011b). The FNHS liquid nitrogen piping is designed, constructed, and tested in accordance with ASME B31.3, Process Piping(ASME,2013). The FNHS vaporizers, receivers, and bulk liquid nitrogen tanks are designed, constructed, and tested to the ASME Boiler and Pressure Vessel Code, Section VIII, Rules for Construction of Pressure Vessels(ASME,2010). The balance of the equipment included in the FNHS is commercially available and is designed to standards satisfying the system operation. | |||
The design basis of the FNHS includes: | |||
Provide nitrogen gas at the pressures and flow rates to operate sampling equipment in the RLWS system, the RDS, the TSSS, the MEPS, and the target solution preparation system (TSPS). | |||
Provide nitrogen gas for sparging and mixing of tanks in the RLWS, the TSSS, the MEPS, the RDS, and the IXP system. | |||
Provide liquid and gaseous nitrogen to the TPS. Gaseous nitrogen is used by the TPS to operate pneumatic equipment. Liquid nitrogen is supplied to the TPS cryopumps and the thermal cycling absorption process (TCAP) isotope separation columns. | |||
Provide liquid nitrogen in dewars to the IXP system and the instrument laboratory for equipment cooling. | |||
Provide nitrogen gas to the TOGS for pressure regulation. | |||
Provide nitrogen gas to the PCLS and the FFPS for pneumatic control mechanisms. | |||
The FNHS is not relied upon to prevent accidents that could cause undue risk to the health and safety of the workers and the public or to control or mitigate the consequences of such accidents. | |||
9b.7.8.2 | |||
===System Description=== | |||
Bulk liquid nitrogen is stored in tanks outside the main production facility and is supplied to vaporizer units. The vaporizer units vaporize the liquid nitrogen to provide a clean gaseous | |||
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-15 Rev. 3 nitrogen supply that is piped into the main production facility. A liquid nitrogen supply line upstream of the vaporizers supplies liquid nitrogen from the bulk storage tank into the main production facility via vacuum jacketed cryogenic piping. | |||
The FNHS supplies liquid nitrogen to an adjustable pressure phase separator inside the main production facility that has the capability to store and deliver high quality liquid nitrogen to the TPS. Liquid nitrogen is supplied to a fill station inside the main production facility. The fill station is installed to fill portable dewars for the disbursement of liquid nitrogen in small quantities as needed by facility processes. Liquid nitrogen dewars supplying the IXP are equipped with an excess flow check valve for the protection of supercell and downstream equipment. Off-gassing from the FNHS phase separator and fill station are ventilated through a connection to the radiological ventilation zone 2 exhaust subsystem (RVZ2e) inside the IF. | |||
Inside the RCA a portion of the nitrogen supply gas is piped to a main receiver storage tank which feeds the FNHS ring header. The remainder of the nitrogen supply gas is piped to the TPS room serving the TPS. | |||
A FNHS remote receiver tank is maintained on the FNHS ring header to supply abrupt demands and provide consistent nitrogen gas flow and pressure to all serviced areas in the RCA. The FNHS ring header supplies nitrogen gas to sampling equipment, tank sparging and mixing equipment, and level indication equipment. The FNHS ring header supplies nitrogen gas to each FNHS cooling room receiver tank where it is used by TOGS. | |||
Table9b.7-5 identifies the systems which interface with the FNHS. Figure9b.7-6 provides a process flow diagram for the FNHS. | |||
9b.7.8.3 Operational Analysis and Safety Function The FNHS bulk liquid nitrogen storage tanks are continuously pressurized by the naturally occurring liquid to gas phase change inside the tank with the presence of liquid nitrogen. The FNHS bulk liquid nitrogen storage tank head space pressure is regulated to provide flow to the vaporizer. A pressure relief system with a vent path to the atmosphere is maintained on each bulk liquid storage tank to prevent overpressurization of the vessel. | |||
Liquid nitrogen is directed from the pressurized bulk storage tank to vaporizers where it is heated and vaporized to nitrogen gas. The gaseous nitrogen supply is regulated through a control manifold designed to control the pressure and prevent possible liquid carryover to the FNHS end users. The FNHS bulk liquid nitrogen storage tank and vaporizers supply nitrogen gas to the main FNHS receiver tank, the facility nitrogen gas ring header, and the FNHS remote receiver tank located inside the RCA. The control manifold ensures that adequate pressure is maintained within the main production facility. Overpressure protection is provided on the FNHS gaseous facility supply line. | |||
The FNHS cooling room receiver tanks are filled from the facility nitrogen gas ring header by opening a normally closed manual valve allowing flow to the tank corresponding to the actuated valve. Once pressure has equalized the valve is closed and the tank is placed in service. | |||
Redundant isolation upstream of the cooling room remote receiver tanks ensures that a direct path from the atmosphere inside confinement boundaries to outside those areas are not created. | |||
The manual isolation provided is maintained normally closed and administrative controls ensure | |||
Table 9b.7 Radioactive Liquid Waste Immobilization System Interfaces Interfacing System | Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-16 Rev. 3 that the valve is only opened to service the TOGS when the associated IU and TOGS are not in service. The isolation prevents backflow from the TOGS into normally occupied IF spaces. | ||
Shielding and radiological protection is not required for the FNHS. The FNHS contains no SNM. | |||
The FNHS is nonsafety-related. | |||
9b.7.8.4 Instrumentation and Control The FNHS is comprised of a packaged skid control system that includes system instrumentation. | |||

9b.7.9.2 | |||
===System Description=== | |||
The FSDS removes domestic sanitary waste and wastewater from the areas of the main production facility (not inside the RCA), the storage building, and the resource building; and discharges sanitary waste and wastewater to the City of Janesville public sewer main. | |||
The FSDS building sewer removes sanitary waste via a gravity drainage system. The subsystem includes distribution piping, pipe fittings, isolation valves, backwater valves, vents, traps, cleanouts, manholes, and fixtures. | |||
9b.7.9.3 Operational Analysis and Safety Function The piping in the FSDS building sewer is sloped per the Wisconsin Administrative Code to ensure directed flow to the City of Janesville public sewer main. Building drains that are subject to backflow are protected with a backwater valve or sump and pumping equipment to comply with applicable requirements of the Wisconsin Administrative Code. | |||
Shielding and radiological protection is not required for the FSDS. Sanitary waste sources contain no SNM. | |||

Bulk chemical storage is provided in the storage building. Chemical storage is also provided in the chemical storage and preparation room in the main production facility, which is located outside the RCA. Storage of compressed oxygen gas, used as a reagent, is provided by the FCRS. Compressed oxygen is supplied to the TOGS to facilitate the recombination of radiolytic hydrogen. Other chemical reagents are used for batch production, solution adjustment, and process flushing. | |||
Chemical reagents are placed into volume-limited FCRS containers for transfer to process tie-in location tanks and into single-use laboratory scale containers (e.g., flasks, syringes, pipets) for import into hot cells inside the RCA. | |||
Reagents transported in portable containers are transferred into the tanks and pumped on demand directly into the respective process tie-in locations for: | |||
TSPS uranyl sulfate solution preparation and adjustment; MEPS extraction, purification, and flushing; IXP system iodine extraction, purification, and flushing; RLWS system pH adjustment; RLWI system flushing; VTS flushing and adjustment of target solution in the TSSS; PVVS condensate pH adjustment and flush; and PSB flushing. | |||
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-18 Rev. 3 Reagents in laboratory containers are manually introduced into the MEPS purification hot cells through hot cell pass-throughs. Hot cell master-slave manipulators are used to add chemicals to the laboratory scale purification processes performed in the hot cells. | |||
Compressed oxygen cylinders are stored inside the IF to service the TOGS. Compressed oxygen is routed through dry particulate filters, regulated, and distributed to the TOGS. | |||

9b.7.10.3 Operational Analysis and Safety Function Bulk liquid and solid chemicals and chemical reagents are received, stored, maintained, and used in accordance with the chemical hygiene plan and are stored per their applicable safety data sheets. | |||
The FDWS provides demineralized water to both the storage building and the chemical storage and preparation room for chemical reagent preparation. Individual acid, base, and organic waste containers are provided for disposal of chemicals. | |||
Reagents from FCRS process delivery tanks are pumped directly into the respective process tie-in points at controlled flow rates and temperatures in accordance with the process requirements. | |||
Administrative and engineered controls, including accurate identification of reagents inside process delivery tanks and containers, and color-coded and size specific connections, ensure that reagents are not inadvertently supplied at incorrect process tie-in points. The FCRS process delivery tanks are volume limited, thereby setting maximum volume of reagents that can be supplied to respective production-related processes. | |||
Mixing of acids and bases could cause a highly exothermic reaction. As such, bulk quantities of acids are stored separately from the bases and hydrogen peroxide in segregated storage spaces within the storage building. Small volumes of chemicals to be used in laboratory settings and in processes are stored and labeled in accordance with their applicable safety data sheets. | |||
Table13b.3-1 provides a list of chemicals within the SHINE facility. | |||
The storage and delivery of oxygen gas inside the RCA complies with fire hazard analysis (FHA), | |||

9a2.1.1.2
System Description
Radiological Ventilation Zone 1 RVZ1 is divided into two subsystems: RVZ1r and RVZ1e. A flow diagram of RVZ1r is provided in Figure9a2.1-2. A flow diagram of RVZ1e is provided in Figure9a2.1-3.
RVZ1r provides cooling for systems within the irradiation unit (IU) cell and the target solution vessel(TSV) off-gas system(TOGS) cell. RVZ1r recirculates, filters, and cools air within the IUcell and the TOGS cell. The system includes two fan coil units and associated ductwork and dampers per each set of lU/TOGS cells. Each set of RVZ1r units is located within the cooling room and forms a portion of the confinement boundary for the lU/TOGS cells that it serves.
RVZ1r provides sampling, ventilation, and cleanup connections for the primary confinement.
RVZ1e exhausts air from the areas with a high potential for contamination in the facility. The air is filtered and directed out of the main production facility through the exhaust stack. The subsystem includes fans, filters, ductwork, dampers, and high efficiency filter banks. It also includes the necessary transfer ductwork to allow makeup from the RCA general area into the exhausted areas.
RVZ1e is designed to maintain ventilation zone 1 areas at a lower pressure than ventilation zone2 areas. The design inhibits backflow with the use of backflow dampers at the discharge of the RVZ1e and RVZ2e exhaust fans in order to minimize the spread of contamination. RVZ1e ductwork provides sampling locations for radiation detectors, fire detection equipment, stack release monitoring, and an exhaust stack connection point for RVZ2e and the process vessel vent system(PVVS).
The RVZ1 serves the following areas:
IU cells TOGS cells Tritium purification system (TPS) process equipment Primary closed loop cooling system (PCLS) expansion tank Uranium receipt and storage system (URSS) glovebox Radioactive liquid waste immobilization (RLWI) shielded enclosure Supercell Target solution preparation system (TSPS) glovebox Target solution dissolution tanks Target solution preparation tank Radiological Ventilation Zone 2 RVZ2 includes three subsystems:RVZ2e, RVZ2s, and RVZ2r. A flow diagram of RVZ2e is provided in Figure9a2.1-4. A flow diagram of RVZ2s air handling units(AHUs) is provided in Figure9a2.1-5. A flow diagram of RVZ2s distribution and RVZ2r is provided in Figure9a2.1-6.
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-3 Rev. 3 RVZ2e exhausts air from the general areas of the RCA. The subsystem includes fans, filters, ductwork, dampers, and high efficiency filter banks. It also includes the necessary transfer ductwork to allow makeup from the RCA general area into the exhausted rooms. The transfer ductwork is located in the following spaces:
from the irradiation facility(IF) general area to the TPS room; from each of the cooling rooms to the IF general area; from the analytical lab to the quality control (QC) lab; from the QC lab to the radioisotope production facility (RPF) general area; from the RPF general area to the transfer aisle; from the storage room to the preparation room; from the RPF general area to the RLWI skid; and from the transfer aisle to the radioisotope process facility cooling system (RPCS) room.
RVZ2 provides ventilation and humidity control for ventilation zone 2 rooms within the RCA.
RVZ2e provides an exhaust path for the QC lab and analytical laboratory fume hoods within the RCA and maintains the QC lab and analytical labs at positive pressure with respect to the ventilation zone 2 general area. The system is designed to maintain the RCA at a lower pressure than areas outside of the RCA. The RVZ2e design inhibits backflow within ductwork that could spread contamination. RVZ2e ductwork provides sampling locations for engineered safety features actuation system (ESFAS) radiation detectors and fire detection equipment.
RVZ2s supplies conditioned outside air into the RCA to provide ventilation and to make up for RVZ1e and RVZ2e exhaust volumes. The system includes AHUs, filters, ductwork, and dampers. RVZ2s provides cooling, heating, humidification for all systems within ventilation zone2 as well as maintains the QC lab and analytical labs at positive pressure with respect to the ventilation zone 2 general area.
RVZ2r recirculates, filters, and conditions air within the RCA. The system includes AHUs, filters, ductwork, and dampers. The RVZ2r units are located within the RCA. RVZ2r provides additional cooling for systems within ventilation zone 2. RVZ2r is also used to cool air being supplied to the supercell, which reduces the flow rate required to cool the equipment within the supercell. The filters and bubble-tight dampers on the inlet side of the supercell are part of RVZ1e.
Areas served by RVZ2 include:
TPS fume hoods QC lab hood Analytical lab hood RCA exhaust filter room Access control area Don/doff rooms Decontamination room Labyrinths Analytical lab QC lab Workspace Transfer aisle RPCS room Storage rooms
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-4 Rev. 3 Preparation room Tool crib Vestibule Primary cooling rooms IF general area Neutron driver assembly system (NDAS) service cell TPS room Supercell Radiological Ventilation Zone 3 Under normal operating conditions, RVZ3 transfers air from ventilation zone 4 to ventilation zone3 then from ventilation zone 3 to ventilation zone 2 via engineered pathways. A flow diagram of RVZ3 is provided in Figure9a2.1-7. Under accident conditions, bubble tight dampers close, isolating ventilation zone2. The design of RVZ3 inhibits backflow within ductwork that could spread contamination. Transfer ductwork from ventilation zone 3 to ventilation zone 2 is provided for the following spaces:
from the shipping/receiving alcove to the IF general area; from the shipping/receiving alcove to the transfer aisle; from the main RCA ingress/egress to the access control; from the RPF emergency exit to the RPF general area; from the IF emergency exit to the IF general area; and from the mezzanine emergency exit to the IF general area.
9a2.1.1.3 System Operation RVZ1e areas draw ambient supply air from adjacent ventilation zone 2 spaces, except for the supercell. During normal operation, areas ventilated by RVZ1e are maintained at negative pressure with respect to their surrounding ventilation zone 2 spaces. The supercell is supplied air directly from RVZ2r. The air supplied to the supercell is exhausted by RVZ1e.
RVZ1e contains redundant fans that are capable of continuous operation. During normal operation, one fan is operating while the other fan is on standby. If the operating fan fails, the standby fan will start automatically.
The exhaust from RVZ1e areas collects in the RVZ1e system duct header and then is drawn through the final filter banks on the mezzanine. These filter banks contain high efficiency particulate air (HEPA) filters and carbon adsorbers upstream of the building isolation dampers.
These filters and adsorbers are equipped with differential pressure monitoring equipment and are periodically monitored by operations personnel. The building isolation dampers are safety-related automatic isolation dampers controlled by ESFAS. These dampers are located at the RCA boundary, upstream of the exhaust fans and exhaust stack.
Negative pressure is maintained in the ductwork to control contamination and maintain pressure gradients. System operation between RVZ1e, RVZ2e, and RVZ2s is coordinated such that the overall airflow and pressure gradients are maintained. The pressure gradients create flow patterns that direct air towards areas of increasing contamination potential. This is maintained by the variable frequency drives (VFDs) on the exhaust fans. Minimum airflow will be maintained during normal system operation.
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-5 Rev. 3 During upset conditions, affected sections of the RVZ1e, RVZ2s, and RVZ2e ventilation systems are isolated as required for the specific event or indication. Bubble tight dampers close, based on detection of radiation more than 60 times normal background radiation levels. The RVZ1e supply flow path to the supercell includes nonsafety-related HEPA and carbon filters. The RVZ1e exhaust flow path from the supercell includes nonsafety-related HEPA filters and safety-related carbon filters. The remaining RVZ1e flow paths that exhaust confinements for fission products contain nonsafety-related HEPA and carbon filters. The RVZ1e safety-related, redundant bubble-tight dampers are situated as near to the confinement boundary as practical.
The IU cell exhaust flow path of RVZ1e provides ventilation of the IU cell and TOGS cell via the PCLS expansion tank headspace. This path is equipped with radiation monitoring instrumentation and redundant isolation valves. Between the RVZ1e IU cell radiation instrumentation and RVZ1e IU cell isolation valves is an isolation lag tank. If radiation measurements exceed 60 times normal background radiation, the TSV reactivity protection system (TRPS) initiates an IU Cell Safety Actuation, which closes the RVZ1e IU cell isolation valves. The isolation lag tank provides an exhaust gas delay time greater than the closing time of the valves.
Upon loss of power, loss of signal, or ESFAS initiation of confinement, dampers seal the affected confinement areas within 30seconds.
The RVZ1r fan coil units (FCUs) are capable of continuous operations. The RVZ1r recirculates, and cools air within the IU cell and TOGS cell. The IU cell and TOGS cell are established as low leakage boundaries.
RVZ2e fans are capable of continuous operation. RVZ2e exhausts the various normally occupiable rooms within the RCA as well as fume hoods, filters the air via HEPA filter banks and discharges to the facility stack. Exhaust headers are maintained at a negative pressure by the VFD. Negative pressure is maintained in the ductwork to control contamination and maintain pressure gradients. The exhaust from RVZ2 areas collects in the RVZ2 system duct header and then is drawn through final HEPA filters and carbon adsorbers prior to discharge to the exhaust stack.
During normal operation, ventilation zone 2 areas are maintained at negative pressure with respect to RVZ3 airlocks. The speed of the RVZ2e exhaust fans is controlled to maintain a negative pressure setpoint in the RVZ2e exhaust header. Minimum airflow will be maintained during normal system operation.
RVZ2s AHUs are capable of continuous operation. Ventilation zone 2 areas are directly supplied air via the RVZ2s AHUs. The AHUs supply conditioned, 100percent outside air. Each AHU contains filters, pre-heat and cooling coils, and supply fans. The supply system includes redundant AHUs. If a single AHU fails, the standby AHU will start automatically. The AHUs normally supply a constant volume of conditioned air to RVZ2 areas.
The RVZ2s supply duct contains safety-related automatic isolation dampers controlled by ESFAS. These dampers are located at the RCA boundary.
RVZ2r AHUs are capable of continuous operation. The RVZ2r AHUs further condition the air in the RCA general area to comfort levels.
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-6 Rev. 3 The RVZ1e and RVZ2e subsystems combine downstream of each subsystems respective filter banks, RCA isolation bubble-tight dampers, and exhaust fans, as shown in Figure9a2.1-8. The PVVS delay bed discharge is also combined with the RVZ1e and RVZ2e flow downstream of the exhaust fans and upstream of the stack release monitor. The discharge of the stack is approximately 10feet above the roofline of the facility and will maintain a minimum discharge velocity of 3,000fpm.
9a2.1.1.4 Instrumentation and Control The RV systems are designed such that the process integrated control system (PICS) monitors the system equipment, flow rates, pressures, and temperatures. Instrumentation monitors the ventilation systems for off-normal conditions and signal alarms as required. The PICS starts, shuts down, and operates the RV system in normal operating modes. Coordinated controls maintain negative pressurization to create flow patterns that direct air toward areas of increasing contamination potential.
PICS monitors the differential pressures across all the filters in the RVZ1e and RVZ2e filter banks and produces an alarm if the differential pressure of any filter is above its established limit.
9a2.1.1.5 Inspection and Testing The ventilation systems are balanced upon installation. Control systems are tested to assure that control elements are calibrated and properly adjusted. Safety-related isolation dampers are inspected and tested as required by, and in accordance with, SectionDA of ASME AG-1, Code on Nuclear Air and Gas Treatment (ASME,1999). Safety-related ductwork will be inspected and tested as required by, and in accordance with, SectionSA of ASME AG-1 (ASME,1999).
9a2.1.1.6 Nuclear Criticality Safety Subsection6b.3.2.7 provides a discussion related to the nuclear criticality safety requirements for the URSS glovebox ventilation. Subsection6b.3.2.4 provides discussion related to the nuclear criticality safety requirements for the TSPS glovebox ventilation.
9a2.1.1.7 Technical Specifications Certain material in this subsection provides information that is used in the technical specifications. This includes limiting conditions for operation, setpoints, design features, and means for accomplishing surveillances. In addition, significant material is also applicable to, and may be used for, the bases that are described in the technical specifications.
9a2.1.2 NON-RADIOLOGICAL AREA VENTILATION SYSTEM The non-radiological area ventilation system is the facility ventilation zone 4 (FVZ4) system.
Ventilation zone 4 consists of areas which are located within the main production facility, but outside of the RCA. The FVZ4 system is completely independent of the RV systems described in Subsection9a2.1.1. The FVZ4 system supply AHUs draw at least 10percent outside air to make up for air exhausted and exfiltrated. The outside air is mixed with recirculated air and conditioned through the AHUs before being supplied to FVZ4 areas. FVZ4 exhaust streams exhaust directly
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-7 Rev. 3 to the outside of the main production facility. No radiation detectors are provided in the FVZ4 exhaust, as contamination is not expected to be present in the FVZ4 system.

FVZ4 Exhaust Subsystem (FVZ4e)
FVZ4e serves the following locations of the non-RCA area of the facility:
Janitor closets Chemical storage Restrooms Battery rooms Control room The FVZ4e subsystem exhausts the battery rooms and UPS rooms within ventilation zone 4 to maintain the hydrogen concentration below 2percent and the temperature under 120°F. Upon a loss of power, the battery rooms will be exhausted by dedicated fans powered by the standby generator system (SGS).
Dampers are provided to isolate the FVZ4 exhaust air subsystem to each battery room and each UPS room, independently, on an initiation signal from each locations fire suppression system.
The distribution of the FVZ4e subsystem is provided in Figure9a2.1-12.
FVZ4 Room Cooling Recirculation Subsystem (FVZ4r)
The FVZ4r subsystem recirculates and cools air within the human machine interface (HMI)/
telecommunication room and the process/server room. The system is made up of two split systems that cool the server space. The FVZ4r subsystem provides equipment status to the PICS.
9a2.1.2.4 Radiation Protection and Criticality Safety There are no radiation contamination hazards or criticality safety hazards associated with the FVZ4 system.
9a2.1.2.5 Instrumentation and Control The supply air subsystem HVAC controls operate through the PICS. The FVZ4 system is designed such that the PICS monitors and controls the non-RCA recirculation air subsystem ventilation equipment, flow rates, pressures, and temperatures. Instrumentation monitors the ventilation systems for off-normal conditions and signal alarms as required.
The PICS performs the following functions relative to FVZ4:
starts, shuts down, and operates FVZ4 in normal operating modes; monitors the return and supply temperature from the AHUs; and monitors the pressure differential across the filters.

9a2.1.3 FACILITY CHILLED WATER SYSTEM The facility chilled water system (FCHS) is a closed-loop, forced circulation system which provides chilled water to the cooling coils of the RVZ2s subsystem AHUs, which are located outside of the RCA. FCHS also provides chilled water to the cooling coils of the FVZ4 AHUs. The FCHS rejects heat to the atmosphere.
9a2.1.3.1 Design Bases The design bases of the FCHS include:
Circulate chilled water through the cooling coils of RVZ2s subsystem AHUs.
Circulate chilled water through the cooling coils of the FVZ4 AHUs.
The FCHS is constructed to the requirements in Chapters SPS 361 and SPS363 of the Wisconsin Administrative Code.
9a2.1.3.2
System Description
The FCHS is nonsafety-related. Primary components of the FCHS include:
Air-cooled chillers; Chilled water pumps, associated piping and valves, and makeup water and water treatment equipment; and An expansion tank.
9a2.1.3.3 System Operation The system is powered by the normal electrical power supply system (NPSS) under normal operating conditions.
The system is a variable closed-loop cooling system using VFDs on each centrifugal pump to supply a single pump header. Each chiller supply line maintains a modulating flow control valve capable of fully-open or fully-closed valve position. Each RVZ2s subsystem and FVZ4 AHU cooling fluid supply line maintains a modulating flow control valve capable of fully-open or fully-closed valve position. System flow, temperature, and differential pressures are utilized by an FCHS controller to signal valves, pumps, and chillers to come online, vary speed, or secure as necessary to meet system setpoints during normal system operation.
PICS monitors the RVZ2s and FVZ4 airstream delivery temperatures. An FCHS controller monitors flow control valve position and delivers a signal to individual valves to adjust cooling
Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9a2.1-10 Rev. 3 water flow rates in response to signals sent to the load instrumentation. A flow control valve is maintained on the system bypass line and is controlled by input signals from FCHS controller inputs made by chiller supply, RVZ2s, and FVZ4 modulating flow control valves.
Each pumps VFD status is monitored by local chiller equipment for fault status and motor amps.
When the FCHS controller registers that a pump is not running, and a stop command has not been issued from the control panel, an alarm is generated at the control panel and the standby pump is automatically started.
Local chiller equipment monitors differential pressures across each chiller and the chillers running status. Upon communication of a fault alarm, an FCHS controller isolates that chillers modulating flow control valve and issues a start command to the back-up chiller. System pumps respond accordingly to the loading of the chillers via a local controller. Chiller fault alarms on multiple chillers initiates an automatic shutdown of the system through an FCHS controller.
The system maintains alarms monitored by PICS and displays them at operator workstations for system volumes out of range.
9a2.1.3.4 Radiation Protection There are no radiation contamination hazards associated with the FCHS.
9a2.1.3.5 Instrumentation and Controls Instrumentation monitors the system for off-normal conditions and signal alarms as required.

This section describes the handling and storage of target solution within the irradiation facility (IF). The chemical properties of the target solution are described in Section4a2.2, including uranium concentration, density, and pH.
Detailed descriptions of the processes involving irradiated and unirradiated special nuclear material (SNM), including the byproduct material produced as a result of the irradiation of SNM, are provided in Section4b.4. Equipment, application of administrative controls, and design features related to the target solution lifecycle are also discussed in Section4b.4. A detailed description of the target solution lifecycle is provided in Section9b.2.
Physical protection of the target solution from theft or diversion is ensured via the implementation of the Physical Security Plan, described in Section12.8. The primary closed loop cooling system (PCLS) removes heat from the target solution vessel (TSV), neutron multiplier, and components of the subcritical assembly system (SCAS) during irradiation of the target solution, as described in Section5a2.2. Radiological considerations during normal operations related to the handling and storage of target solution are described in Section11.1. An analysis of accident scenarios involving the mishandling or malfunction of target solution within the IF is provided in Subsection13a2.1.4.
9a2.2.2 IRRADIATION FACILITY TARGET SOLUTION STORAGE AND HANDLING After target solution is prepared and qualified in the target solution preparation system (TSPS), it is transferred to the target solution hold tank prior to transfer into the TSV. Target solution is transferred from the target solution hold tank to the TSV via the TSV fill lift tank.
The target solution hold tank is at an elevation below that of the TSV to prevent an accidental gravity-driven transfer of target solution to the TSV. The vacuum transfer system (VTS) is used to transfer the target solution to the TSV in a controlled manner, both with respect to fill rate and fill volume. A description of the incremental process used to fill the TSV is provided in Section4a2.6.1. Target solution batches that have been previously irradiated are returned to the target solution hold tank from processes in the hot cells or from the target solution storage tank.
9a2.2.3 IRRADIATION FACILITY TARGET SOLUTION HANDLING EQUIPMENT The following is a list of major equipment that interacts with target solution in the IF.
Target Solution Vessel Quantity: 8 Location: Inside irradiation unit (IU) cell TSV Dump Tank Quantity: 8 Location: Inside IU cell
Chapter 9 - Auxiliary Systems Handling and Storage of Target Solution SHINE Medical Technologies 9a2.2-2 Rev. 0 9a2.2.4 STORAGE OF TARGET SOLUTION Storage of target solution in the IF is limited to storage in the TSV dump tanks following irradiation in the TSV.
9a2.2.5 CRITICALITY CONTROL FEATURES Protection against inadvertent criticality in the TSV dump tank is discussed in Subsection4a2.6.3. Protection against inadvertent criticality in the TOGS is discussed in Subsection4a2.8.5. Reactivity control for the SCAS is discussed in Section4a2.6.
9a2.2.6 BIOLOGICAL SHIELDING The irradiation cell biological shield (ICBS) ensures that the projected radiation dose rates and accumulated doses in occupied areas within the IF do not exceed the limits of 10 CFR 20.
Furthermore, the dose reduction by the ICBS supports the radiation exposure goals defined in the as low as reasonably achievable (ALARA) Program, as described in Section11.1.
Section4a2.5 provides a detailed description of the ICBS.
9a2.2.7 TECHNICAL SPECIFICATIONS Controls on target solution during handling and storage, including testing and surveillance, are described in the technical specifications.
Chapter 9 - Auxiliary Systems Fire Protection Systems and Programs SHINE Medical Technologies 9a2.3-1 Rev. 1 9a2.3 FIRE PROTECTION SYSTEMS AND PROGRAMS 9a2.3.1 FIRE PROTECTION PLAN AND PROGRAM The Fire Protection Plan describes the overall facility Fire Protection Program (FPP). The FPP describes the fire protection organization and responsibilities, design and programmatic approach, and means to limit the probability and consequences of fire at the SHINE facility. The Fire Protection Plan establishes the requirements to be satisfied by the facility fire protection program. This plan establishes a program that represents an integrated effort involving components, procedures, analyses, and personnel used in defining and carrying out activities of fire protection. It includes system and facility design, fire prevention, fire detection, annunciation, confinement, suppression, administrative controls, inspection and maintenance, training, quality assurance, and testing. The established fire protection program elements, systems, structures, and components are subject to the SHINE Quality Assurance Program, as described in the Quality Assurance Program Description. The elements of the FPP work together to satisfy the requirements of applicable regulatory requirements presented in 10CFR50.48(a). The FPP is comprised of the following lower tier documents which are developed and maintained as part of the overall FPP.
Fire Hazards Analysis (FHA);
Safe Shutdown Analysis; Pre-Fire Plans; and Administrative controls (e.g.,implementing procedures, drawings, calculations, analyses, specifications).
Development of the FPP is informed by the guidance provided in National Fire Protection Association (NFPA) 801, Standard for Fire Protection for Facilities Handling Radioactive Materials (NFPA,2014). The structure and content of the FPP are based on the precepts of 10CFR50.48(a) and NFPA801. The FPP ensures, through the application of the defense-in-depth concept, that a fire will not prevent the performance of necessary safety-related functions and that radioactive releases to the environment, in the event of fire, will be minimized.
9a2.3.2 DESIGN BASES The concept of defense-in-depth is fundamental to the FPP. Fire protection defense-in-depth for the SHINE facility is defined as follows:
Prevent fires from starting, including limiting combustible materials; Detect, control, and extinguish those fires that do occur to limit consequences; and Provide protection for safety-related structures, systems, and components(SSCs) so that a continuing fire will not prevent the safe shutdown of the irradiation units or cause an uncontrolled release of radioactive material to the environment.
The FPP is developed and implemented to accomplish these criteria.
9a2.3.3 FIRE HAZARD ANALYSIS The foundation of the facility fire protection design is the FHA. The FHA establishes and describes individual facility fire areas, which are unique areas separated by fire-rated construction or administrative controls to prevent the spread of fire between adjacent fire areas.
Chapter 9 - Auxiliary Systems Fire Protection Systems and Programs SHINE Medical Technologies 9a2.3-2 Rev. 1 The FHA is performed to determine the hazard posed by operations and contents resident to the fire area of concern. This analysis identifies the level of fire protection needed to provide the desired confinement/control of postulated fires. The analysis demonstrates the adequacy of protection provided, and, if necessary, the need for additional protection.
The primary objectives of the FHA are:
Establish or identify fire area boundaries, Identify fire hazards within the analyzed area, Determine worst case fire effects on safe shutdown capability of the irradiation units(IUs) and the potential for uncontrolled release of radioactive materials, and Evaluate the adequacy of fire protective features provided.
The FHA is maintained in accordance with the FPP for identified fire areas and facility changes.
9a2.3.4 SAFE SHUTDOWN ANALYSIS The FPP includes performance of a safe shutdown analysis to demonstrate a means of safe shutdown of the SHINE IUs to ensure they can be placed and maintained in a safe and stable condition following a severe fire in any facility fire area. The analysis also considers the effect of severe fires on safety-related equipment required to prevent uncontrolled releases of radioactive material. A deterministic evaluation is conducted on a fire area by fire area basis to ascertain potential damage and assess the effectiveness of the provided protection.
The fire safe shutdown analysis identifies the means by which safe shutdown of the IUs is accomplished and uncontrolled release of radioactive material is prevented for a fire in each facility fire area. Conduct of the safe shutdown analysis is discussed in detail in implementing procedures and reports. Analysis of safe shutdown and prevention of uncontrolled release of radioactive material for the facility is generally conducted through conduct of the following types of analyses:
Development of performance goals and analysis methodology Selection of credited equipment and systems Performance of cable selection and circuit analysis Performance of functional analysis Development of necessary safe shutdown implementing procedures 9a2.3.5 ADMINISTRATIVE CONTROLS Administrative controls and procedures are established by the FPP to ensure satisfaction of the program goals and maintenance of a fire safe workplace. These procedures ensure policies and procedures are in place to minimize the possibility of fire and to provide equipment and systems necessary to mitigate the effects of fires that do occur. Each of the fire-related procedures is designed to strengthen the defense-in-depth approach to fire protection.
9a2.3.6 REGULATORY AND CODE REQUIREMENTS SHINE fire protection systems are designed to comply with the applicable portions of the nationally recognized codes and standards identified below. Adherence to these codes and standards ensures that the facility fire protection features and systems are available to perform
Chapter 9 - Auxiliary Systems Fire Protection Systems and Programs SHINE Medical Technologies 9a2.3-3 Rev. 1 their functions when required. The SHINE facility is designed to meet the following fire protection objectives:
Prevent fire initiation by controlling, separating, and limiting the quantities of combustibles and sources of ignition.
Isolate combustible materials and limit the spread of fire by subdividing the facility into fire areas separated by fire-rated barriers.
Separate redundant safety-related components and associated electrical divisions to ensure the capability to achieve and maintain safe shutdown and prevent uncontrolled releases of radioactive material as a result of fire.
Provide confidence that failure or inadvertent operation of firefighting systems does not significantly impair the safety capability of credited SSCs.
Provide incipient firefighting capability and access for professional firefighters.
Minimize exposure to personnel and releases to the environment of radioactivity or hazardous chemicals as a result of a fire.
The facility fire protection features and systems are classified as nonsafety-related and generally non-seismic. Facility fire protection features and systems are not required to remain functional following a design basis accident or the most severe natural phenomena.
The design, installation, testing, and surveillance of the facility fire protection features and systems are based on applicable guidance from nationally recognized codes and standards. The codes and standards used and the code-of-record is as defined in the FPP and applicable design documentation.
9a2.3.7 FACILITY FIRE PROTECTION SYSTEM DESCRIPTION The facility is subdivided into fire areas that are separated by fire-rated barriers to limit the spread of fire. The fire area boundaries are described and illustrated in the FHA. In each fire area, the facility fire detection and alarm system provides for the detection and alarm of fire conditions.
Facility fire suppression systems and manual firefighting capability provide for the suppression of fires. These systems consist of the following:
Detection systems for early detection and notification of fire; Fixed automatic fire suppression systems; Manual fire suppression systems and equipment, including hydrants, standpipes, hose stations, and portable fire extinguishers; and A fire water supply system including the fire pump, yard main, and interior distribution piping.
The facility FPP and lower tier documentation provide a complete description of the facility fire protection features and systems.
9a2.3.8 RADIOLOGICAL FIRE HAZARDS Fissionable materials in the form of low-enriched uranium metal and uranium oxide are brought into the facility and used to produce target solution. Target solution is an aqueous uranyl sulfate solution which is irradiated to produce molybdenum-99 (Mo-99) and other medical isotopes.
Following irradiation, the target solution is transferred through piping and tanks for chemical processing in the radioisotope production facility (RPF) to extract Mo-99, other radioisotopes,
Chapter 9 - Auxiliary Systems Fire Protection Systems and Programs SHINE Medical Technologies 9a2.3-4 Rev. 1 and impurities allowing for reuse of the solution in the irradiation process. These processes present a possibility of radiological release from processes, with fire presenting an energetic source that can drive release. Radiological release due to fire is typically associated with combustion of radiologically contaminated ordinary combustible materials or fire damage to confinement systems that could allow release of collocated radiological materials.
Uranium oxide and uranium metal are received and stored in the uranium receipt and storage system(URSS) room. Storage of the uranium metal and uranium oxide is in metal storage canisters. Canisters are stored on metal storage racks to ensure a safe configuration of the stored materials. Uranium metal is received in sufficiently massive configurations that it is not pyrophoric.
The TSPS and URSS rooms are protected with automatic fire detection and provided with appropriate portable fire extinguishers for incipient stage fire suppression. Combustible loading in these rooms is maintained low to prevent fire. Fire response using water-based extinguishants is prohibited; elevated floors of the URSS and TSPS fire area are provided to prevent flooding of these rooms.
Irradiation is performed in the irradiation facility (IF). Chemical processing, to extract medical isotopes from the target solution, is performed in the RPF. The irradiation and chemical processing of radiological materials is discussed in detail in Chapter4.
Once target solution is introduced to the irradiation process, it is contained in pipes and tanks.
These pipes and tanks are located in the IU cells, hot cells, tank vaults, and pipe trenches throughout the IF and RPF. The IU cells, hot cells, tank vaults, and pipe trench structures are constructed of massive steel and concrete barriers to provide radiation shielding. The monolithic construction of these structures provides significant fire separation from the general areas of the IF and RPF. This construction provides protection to the pipes and tanks containing radiological materials. Combustible loading in the spaces within the IU cells, hot cells, tank vaults, and pipe trenches is maintained very low. Combustible materials in these spaces are limited to cable and equipment. Combustible loading in the IF and RPF general areas is maintained low to present a minimal potential for fire. The IF and RPF general areas are equipped with automatic fire detection and provided with portable fire extinguishers to provide incipient fire suppression capability.
Filters contained in the facility ventilation systems that may contain fission products are replaced on a regular basis. Filters are contained in non-combustible ductwork. Areas of the radiologically controlled area(RCA) containing filters are protected with automatic fire detection and portable fire extinguishers. Combustible loading is maintained low in these areas.
The carbon guard beds located in the process vessel vent system (PVVS) are equipped with temperature detection. The guard beds are isolated upon indication of an unacceptable increase in temperature. The carbon delay beds are monitored with in-bed temperature detection and carbon monoxide detectors at the outlet of each carbon delay bed group. The carbon delay beds are equipped with a nitrogen purge line that may be used to extinguish hot spots if detected.
Three facility systems are provided to mitigate hydrogen generation due to radiolysis. These systems are the TSV off-gas system (TOGS), PVVS, and nitrogen purge system (N2PS).
Chapter 9 - Auxiliary Systems Fire Protection Systems and Programs SHINE Medical Technologies 9a2.3-5 Rev. 1 TOGS is the subcritical assembly system (SCAS) gas management system. The TOGS sweeps radiolysis and fission product gases from the TSV during irradiation and from the TSV dump tank during cool down. The TOGS is located in the TOGS cell of each IU. During target solution irradiation, iodine and noble gases are formed by fission and decay, and hydrogen and oxygen are formed by radiolysis. The hydrogen concentration in the TSV headspace is normally maintained below lower flammability limit (LFL) by using air as a sweep gas. The TOGS system is described in detail in Section4a2.8.
The PVVS provides ventilation for the tanks in the RPF. The system dilutes radiolytic hydrogen generated in RPF tanks and captures or delays radiological off-gas prior to release out the stack.
Blowers at the discharge of the system develop a slight vacuum to pull air across the headspace of each tank. The flow rates across each tank are balanced such that radiolytic hydrogen generated in each tank is diluted below the hydrogen LFL. The PVVS is described in detail in Section9b.6.
The N2PS provides back-up sweep gas flow in the form of stored, pressurized nitrogen gas.
Upon a loss of power, or the loss sweep gas flow in an IU as determined by the TSV reactivity protection system (TRPS), solenoid valves on the N2PS discharge manifold will fail open releasing nitrogen to the IU cell supply header. Upon a loss of sweep gas flow in an IU, nitrogen gas supply solenoid isolation valves for that cell will be deenergized to the open position, releasing nitrogen gas to the TSV dump tank in that cell. A flow switch will give indication that nitrogen sweep gas is flowing to the IU cell distribution system. The flow rates into each TSV dump tank are balanced such that the radiolytic hydrogen generated in each tank is diluted to acceptable concentrations. The sweep gas flows through the TSV dump tank, the TSV, and TOGS equipment and piping and is discharged into the PVVS.
Upon a loss of power or loss of sweep gas flow through PVVS as determined by the engineered safety features actuation system (ESFAS), normal radiological ventilation zone2 (RVZ2) flow is isolated and nitrogen purge gas is directed to the RPF distribution header. A flow switch provides indication that nitrogen sweep gas is flowing to the RPF distribution system. The flow rates across each tank are balanced such that the radiolytic hydrogen generated in each tank is diluted below the LFL. The nitrogen gas flows through the existing PVVS piping and into the PVVS.
9a2.3.9 TECHNICAL SPECIFICATIONS The FPP is included in the Administrative Controls section of the Technical Specifications.
Including the FPP in the Administrative Controls section of the Technical Specifications ensures that the FPP elements are available and reliable by requiring that testing, surveillance, and maintenance activities are conducted as required.
Chapter 9 - Auxiliary Systems Communication Systems SHINE Medical Technologies 9a2.4-1 Rev. 0 9a2.4 COMMUNICATION SYSTEMS The facility data and communication system (FDCS) provides the ability to communicate during normal and emergency conditions between the different areas of the main production facility and facility support buildings, as well as locations remote to the SHINE site. Employing the FDCS, SHINE facility operations staff maintain the ability to contact other facility staff as well as announce the existence of an emergency to all areas of the site. The FDCS is designed using multiple diverse subsystems such that a failure of any system does not impair the ability of the other systems to function. The nonsafety-related FDCS supports implementation of SHINE Design Criteria 8, Emergency Capability, as described in Table3.1-3.
The FDCS consists of five subsystems:
Facility voice over internet protocol (VoIP) telephone system Facility overhead public announcement (PA) system Facility sound-powered telephone system Facility radio system (on-site and off-site communications)
Facility information technology (IT) subsystem 9a2.4.1 TELEPHONES The facility uses a commercial telephone communication system that provides for on-site two-way communication, paging and public address, and party-line-type voice communications.
Stations for this system are located throughout the main production facility and outbuildings. In an emergency, this system is available to alert on-site personnel.
The telephone system allows personnel to contact or receive calls from any outside telephone number. In an emergency, this system is used to contact off-site SHINE and emergency support organization personnel, as described in the SHINE Emergency Plan. Designated emergency cell phones are also maintained in the facility control room, emergency support center (ESC) and backup ESC.
As part of the telephone communication system, certain phones are designated as private exchange phones. Communication between these phones takes priority over any activity from outside of the private exchange. The private exchange system allows for incoming and outgoing calls. The telephone communication system contains redundant servers and a battery backup as a means of improving the reliability of the phone system, public address, and private exchange communication paths. The system is also provided standby power from the standby generator system (SGS), as described in Section8a2.2.
9a2.4.2 PUBLIC ADDRESS SYSTEM The PA system uses the telephone communication system to initiate public address announcements. The system also includes dedicated base transmitting units, which are designed to continue to function in the event of a failure of the phone system. Announcements can be made site-wide or to specific predefined zones. The public address system is audible in the following areas:
Occupiable areas of the main production facility radiologically controlled area (RCA)
Normally occupied areas of the main production facility and support buildings
Chapter 9 - Auxiliary Systems Communication Systems SHINE Medical Technologies 9a2.4-2 Rev. 0 Hallways and corridors of the main production facility and support buildings Outdoor areas on the SHINE campus within the controlled access area fence The PA system provides speakers and power distribution for volume levels meeting the audibility requirements of National Fire Protection Association(NFPA) 72, National Fire Alarm and Signaling Code, Chapter 24(NFPA,2016).
The PA system includes a prioritization of phone lines such that announcements from the control room override any other use of the PA system. The public address system uses the same redundant servers and battery backup as the telephone communication system.
9a2.4.3 SOUND-POWERED PHONES Sound-powered phones supplement the telephone system for on-site communications. The system uses portable sound-powered telephones that can plug into local terminal jacks. The sound powered telephones are located in areas where critical operations and response activities are anticipated to occur. The sound-powered telephones utilize the users voice to create the necessary power for reliable and uninterrupted communications in the event of an emergency.
The phones operate independent of any power source and are not affected by loss of power to the facility.
9a2.4.4 RADIO SYSTEM Hand-held portable radios operating on ultra high frequency (UHF) bands are provided. These radios are powered by replaceable, rechargeable battery packs and once charged are independent of facility power until recharging is needed. Base station radios for communication with the portable radios are provided in select locations.
The radio system contains equipment necessary to communicate with designated off-site emergency support organizations. The system allows for communication with the two primary emergency support organizations (the Janesville Fire Department and the Janesville Police Department) using P25 transmission protocols. Standby power for the facility radio system is provided by the SGS.
9a2.4.5 INFORMATION TECHNOLOGY The information technology system provides corporate network services and connectivity to the internet for the SHINE facility. The IT system supports nonsafety-related personnel information technology needs. The IT system acts as the historian for the process integrated control system (PICS), receiving information from the PICS via data diode such that no inputs can be provided to the PICS from off-site sources. The IT system can also be used to transmit information received from PICS to off-site locations if required.
9a2.4.6 TESTING REQUIREMENTS The design of the communications systems permits routine testing and inspection without disruption to normal communications. Testing is performed in accordance with the SHINE Emergency Plan in order to ensure communications systems operability.
Chapter 9 - Auxiliary Systems Communication Systems SHINE Medical Technologies 9a2.4-3 Rev. 0 9a2.4.7 PHYSICAL SECURITY The use of the FDCS for security purposes is addressed in the SHINE Physical Security Plan.

Refer to Section9b.5 for the discussion of possession and use of byproduct, source, and special nuclear material in the radioisotope production facility (RPF).
The IF is designated as a radiologically controlled area as shown in Figure1.3-1. Radiation protection program controls and procedures, including the as low as reasonably achievable (ALARA) program, applicable to the IF are described in Section11.1. Radioactive waste management is discussed in Section11.2. A discussion of the Security Plan is provided in Section12.8. Discussion of the Emergency Plan is included in Section12.7. Fire protection details applicable to the IF are described in Section9a2.3. Technical Specifications include limits that apply to the possession, management, and use of byproduct, source, and SNM.
9a2.5.1 BYPRODUCT MATERIAL The SHINE facility is designed to generate byproduct materials (e.g., molybdenum-99) for use as medical isotopes. Byproduct materials within the IF include fission and activation products generated during irradiation unit (IU) operations, as well as tritium which is used within the neutron driver assembly system (NDAS) to create deuterium-tritium fusion reactions as described in Section4a2.1.
The tritium purification system (TPS) controls the distribution and processing of tritium for the NDAS as described in Section9a2.7. The quantity of tritium within the facility is described in Table11.1-5. The types and quantities of fission and activation byproduct materials, as well as the systems where these byproduct materials are located, are discussed in Section11.1.
Additionally, up to eight (alpha, neutron) neutron sources (e.g., Am-241/Be) with combined strength up to [ ]SRI are used, one in each IU, for IU start-up operations, as described in Section4a2.2.
9a2.5.2 SOURCE MATERIAL Source materials in the IF include the depleted uranium (DU) within TPS and the natural uranium neutron multiplier within the subcritical assembly. The DU within TPS is used as storage beds for tritium gas as described in Section9a2.7. The use of source material within the neutron multiplier is described in Section4a2.2. SHINE uses up to 330 lbs (150 kg) of DU and 51,000 lbs.
(23,000kg) of natural uranium for these purposes.
9a2.5.3 SPECIAL NUCLEAR MATERIAL Special nuclear material (SNM) in the IF includes low enriched uranium (LEU) within the target solution vessel (TSV). LEU is irradiated to produce molybdenum-99 by fission within the IF.
During this process, plutonium is generated in the target solution and the neutron multiplier. Up to [ ]PROP/ECI of LEU are used in the IF to support facility operations. The total LEU inventory for the radioisotope production facility is discussed in Section9b.5.

(250 g) of uranium-235 are used within neutron flux detectors.
Chapter 9 - Auxiliary Systems Cover Gas Control in Closed Primary Coolant Systems SHINE Medical Technologies 9a2.6-1 Rev. 0 9a2.6 COVER GAS CONTROL IN CLOSED PRIMARY COOLANT SYSTEMS The primary closed loop cooling system (PCLS) is the closed loop cooling system that provides cooling to the target solution vessel (TSV). Buildup of radiolysis products in the PCLS is controlled by the ventilation of the PCLS expansion tank by radiological ventilation zone 1 (RVZ1). Cover gas control for the PCLS is further described in Section5a2.2.
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9a2.7-1 Rev. 2 9a2.7 OTHER AUXILIARY SYSTEMS This section describes auxiliary systems in the irradiation facility (IF) that are not described elsewhere.
9a2.7.1 TRITIUM PURIFICATION SYSTEM The tritium purification system (TPS) is a tritium-deuterium isotope separation system designed to receive mixed tritium-deuterium gas from operating neutron driver assembly system (NDAS) units and provide high purity tritium and deuterium streams to each operating NDAS unit. The TPS components are located in the TPS room. The TPS consists of three trains which service the eight NDAS units.
9a2.7.1.1 Tritium Purification System Subsystems 9a2.7.1.1.1 Isotope Separation Subsystem The isotope separation subsystem of each TPS train receives mixed tritium-deuterium gas from operating NDAS units, removes trace impurities from the gas stream, performs isotope separation of the mixed gas stream, and provides controlled flows of high purity tritium to operating NDAS units to drive the tritium-deuterium fusion reaction in the NDAS target chamber.
The TPS isotope separation subsystem also flushes and evacuates process lines before entering a maintenance period and after maintenance is complete.
9a2.7.1.1.2 TPS-NDAS Interface Lines The TPS-NDAS interface lines consist of multiple transfer lines between the main TPS process equipment and each NDAS. The transfer lines travel through subgrade penetrations between the TPS room and each NDAS. Monitoring capability is provided for the interface lines to detect potential tritium leaks. The TPS-NDAS interface lines are protected from mechanical impact between the TPS gloveboxes and subgrade penetrations.
9a2.7.1.1.3 TPS Gloveboxes The TPS gloveboxes are confinement gloveboxes that enclose the isotope separation process equipment. The TPS gloveboxes are maintained at negative pressure relative to the TPS room and have a helium atmosphere. The glovebox atmospheres are cleaned by the secondary enclosure cleanup (SEC) to maintain low levels of tritium contamination and oxygen. A detailed physical description of the TPS glovebox is provided in Subsection9a2.7.1.4.
9a2.7.1.1.4 Secondary Enclosure Cleanup Subsystem The SEC removes tritium from the helium atmosphere of the TPS gloveboxes. The SEC removes tritium in glovebox environments from both chronic sources (leakage and permeation) and accidental releases. The SEC also maintains low levels of oxygen and moisture in the glovebox atmospheres. The SEC uses a combination of cleanup beds to capture elemental tritium and tritiated water. The cleanup beds are periodically replaced to ensure proper SEC function. The SEC recirculates the TPS glovebox atmospheres.
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9a2.7-2 Rev. 2 9a2.7.1.1.5 Vacuum/Impurity Treatment Subsystem The vacuum/impurity treatment subsystems (VAC/ITS) evacuate TPS process lines and remove trace tritium in process waste streams to support normal operations and maintenance operations. Process streams are evacuated through an arrangement of tritium capture beds, and the waste streams are monitored for tritium concentration before exhausting to the facility ventilation.
9a2.7.1.1.6 NDAS Secondary Enclosure Cleanup The NDAS SEC removes tritium from the atmosphere of the NDAS secondary enclosures. The NDAS SEC removes tritium in NDAS secondary enclosure environments from chronic sources (leakage and permeation) that occur during NDAS operation.
9a2.7.1.1.7 Tritium Purification System Room The TPS room houses the TPS gloveboxes, VAC/ITS equipment, NDAS secondary enclosure cleanup equipment, TPS fume hoods, SEC equipment, and supporting control and process equipment.
9a2.7.1.2 Design Bases The TPS maintains the integrity of the TPS confinement boundary by preventing leakage to the IF from the TPS gloveboxes, SEC process equipment, and TPS-NDAS interface lines, which could result in potential off-site exposures to individual members of the public or occupational dose exposures to individual workers in excess of prescribed dose criteria, which are described in Section11.1. TPS isolation functions are actuated by the engineered safety features actuation system (ESFAS) as described in Section7.5.
The TPS prevents leakage from primary confinement boundary through isolation of interface process lines between TPS process equipment and NDAS during and after a design basis seismic event which could result in potential off-site exposures to individual members of the public or occupational dose exposures to individual workers in excess of SHINE's dose criteria, which are addressed in Section11.1. Primary confinement isolation functions are actuated by the target solution vessel (TSV) reactivity protection system (TRPS), as described in Section7.4.
SHINE design criteria applicable to the TPS are described in Section3.1.
9a2.7.1.3 Tritium Purification Process Sequence The TPS isotope separation process begins with a pair of liquid-nitrogen cooled cryopumps that draw in mixed tritium-deuterium target chamber exhaust gas from NDAS units that interface with the TPS respective train. A guard bed in front of the two cryopumps removes moisture impurity before it reaches the cryopumps. The cryopumps are cycled to either capture gas from operating NDAS units or heated to deliver gas to a permeator that provides additional impurity removal of the gas stream.
The permeator inlet receives gas from the target gas receiving cryopumps. As the gas moves through the permeator, impurities are prevented from passing through the permeator wall while hydrogen isotopes permeate across to the permeator outlet, resulting in high purity hydrogen
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9a2.7-3 Rev. 2 isotopes at the permeator outlet. The permeator outlet is connected to a second set of two liquid-nitrogen cooled cryopumps that cycle between recovering gas from the permeator and delivering gas to the isotope separation process. Impurities that build up on the permeator are periodically evacuated to maintain proper permeator functionality.
After passing through the permeator, deuterium and tritium isotopes are separated through the Thermal Cycling Adsorption Process (TCAP). The TCAP separates deuterium and tritium through the thermal cycling of a palladium-based column and a molecular sieve column. By thermally cycling the TCAP columns, pure tritium gas is collected at one end of the palladium-based column and pure deuterium is collected at one end of the molecular sieve column. Tritium is then drawn from the end of the palladium-based column and deuterium is drawn from the molecular sieve column.
TCAP is a batch process. To receive and deliver a continuous supply of gas to and from operating NDAS units, an arrangement of feed, product, and raffinate tanks is used together with the separation columns. The feed tank is used to supply mixed tritium and deuterium gas to the TCAP separation columns, which separates the two isotopes and fills the product and raffinate tank. The product tank is used to supply the tritium target gas interface line, which is used to supply target gas to each operating NDAS. In-process tritium instrumentation monitors the separation process to ensure proper TCAP functionality, The isotope separation equipment is confined inside the TPS gloveboxes. The TPS gloveboxes provide a tritium confinement boundary along with isolation valves to ensure excessive tritium releases to the facility and environment do not occur. The TPS gloveboxes also provide confinement in the event of a breach in the TPS process equipment.
To receive new tritium gas or store process tritium before entering maintenance, the TPS contains tritium storage vessels, such as depleted uranium beds. The uranium storage beds allow tritium to be safely stored during maintenance operations on the TPS. A supply volume provides the ability to add measured amounts of tritium to the TPS from either the storage bed or an external source.
A VAC/ITS contains the support equipment necessary to evacuate TPS process lines to support normal operations and to prepare for TPS maintenance. The VAC/ITS are capable of removing both elemental and oxide forms of tritium. TPS waste streams are monitored for tritium concentration before exhausting to the facility ventilation. The NDAS may be evacuated before some maintenance operations, so the NDAS evacuation waste streams may also be treated in the VAC/ITS to remove tritium before exhausting the NDAS waste stream to the facility ventilation.
Deuterium source gas is supplied to the NDAS for the NDAS ion source from an external bottle supply. Deuterium source gas exhaust is exhausted to the facility ventilation. NDAS target chamber exhaust consisting of tritium and deuterium gas is returned to the TPS for isotope separation. The NDAS may also be flushed with air and evacuated down to vacuum through the VAC/ITS, which may remove trace tritium before the waste stream enters the facility ventilation.
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9a2.7-4 Rev. 2 Table9a2.7-1 provides a description of TPS interfaces. Table9a2.7-2 provides the nominal properties of the tritium supply, return, and raffinate streams. Table9a2.7-3 provides a listing of process equipment associated with the TPS.
Figure9a2.7-1 provides a TPS process flow diagram.
9a2.7.1.4 TPS Glovebox Description The TPS process equipment is enclosed in three gloveboxes, one for each TPS train. The gloveboxes have a stainless steel shell with gloveports and windows on both sides for operator access to equipment. The glovebox has feedthrough connections to allow process tubing, electrical power, and instrumentation lines to pass through the gloveboxes to the TPS process equipment. The gloveboxes have antechambers to facilitate the removal and replacement of internal equipment as needed. External lighting fixtures provide light to the glovebox interiors.
The glovebox volumes are sized such that a release of the tritium and deuterium stored in the glovebox would not result in exceeding the lower flammability limit (LFL) in the glovebox.
9a2.7.1.5 Glovebox Atmosphere Treatment Small amounts of tritium are released into the gloveboxes during normal operation, so the gloveboxes each have a cleanup system designed to treat the atmosphere to minimize the tritium concentration. The glovebox atmosphere normally has a very low tritium concentration. The most significant releases of tritium to the glovebox atmosphere are expected to occur during maintenance activities (e.g., disconnecting beds or pumps for replacement).
The gloveboxes have a recirculating inert atmosphere with minimal helium makeup. The moisture and tritium content in the glovebox is monitored, and at high concentrations the operator is notified by alarms. The SEC cleans the atmosphere to minimize the amount of tritium in the glovebox atmospheres. The glovebox atmospheres exhaust through the SEC into the radiological ventilation zone 1 exhaust (RVZ1e).
The SEC involves molecular sieve beds and a hydride bed to remove most elemental and oxidized tritium. The cleanup beds are replaced as required over the course of operations.
9a2.7.1.6 Radiological Protection The processes associated with the TPS are performed within gloveboxes to minimize the exposure of individuals to tritium. The TPS equipment outside the gloveboxes that can contain tritium is normally under partial vacuum. Monitors are located near tritium tubing and at glovebox workstations to identify tritium leaks. The TPS is designed to maintain occupational exposures to tritium to within as low as reasonably achievable (ALARA) program goals. Releases of tritium to the facility or environment are within 10 CFR 20 limits.
Process lines that penetrate the glovebox confinement boundaries have isolation valves that close on high tritium alarm in the glovebox. In the event of a tritium release, the glovebox may be isolated from the rest of the TPS process and IF through actuation of the isolation valves.
Isolation valves are also located on process lines at the interface between the TPS and NDAS units that can be closed to support confinement of an irradiation unit (IU) cell.
Security-Related Information - Withheld under 10 CFR 2.390(d)
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9a2.7-5 Rev. 2 TPS process equipment and tubing is designed and fabricated with low leakage rate requirements to ensure low tritium leakage to the glovebox atmosphere or IF. Tritium is supplied to the NDAS at sub-atmospheric pressure which reduces leakage potential.
Evaluation of accidents involving releases of tritium from the TPS is discussed in Subsection 13a2.1.12.
9a2.7.1.7 Instrumentation and Controls The process integrated control system (PICS) provides normal monitoring and control of process variables and control components not important to the safe operation of the TPS. Section 7.3 provides a detailed description of the PICS.
The ESFAS monitors the TPS exhaust to facility stack and TPS confinements for tritium. If the tritium concentration in the TPS exhaust to facility stack exceeds 1 Ci/m3, the ESFAS initiates a TPS Process Vent Actuation. If the tritium concentration in one of the TPS confinements exceeds 1,000 Ci/m3, the ESFAS initiates a TPS Train Isolation for the affected train. The ESFAS also initiates a TPS Train Isolation when the TPS target chamber supply or exhaust pressure for an IU cell exceeds 8 psia, indicating a breach in the tritium boundary. Section 7.5 provides a detailed description of the ESFAS.
9a2.7.1.8 Technical Specifications Certain material in this subsection provides information that is used in the technical specifications. This includes limiting conditions for operation, setpoints, design features, and means for accomplishing surveillances. In addition, significant material is also applicable to, and may be used for the bases that are described in the technical specifications.
9a2.7.2 NEUTRON DRIVER ASSEMBLY SYSTEM SERVICE CELL The NDAS service cell (NSC) is a dedicated work area provided to support the staging, commissioning, maintenance, and disposal of a single NDAS unit. The NSC provides additional space for maintenance activities that are difficult or impossible to perform when an NDAS is installed in an IU cell.
9a2.7.2.1 Design Bases The NSC accommodates commissioning, maintenance, and disposal activities for the operational lifetime of each NDAS.
9a2.7.2.2
System Description
The NSC is a roofless room formed by a shared wall with the [
]SRI on the north, an exterior building wall on the east, a wall facing the laydown area on the south, and a wall on the west. The NSC contains a service pit to allow installation of a dedicated target for NDAS beam testing. Outside of the NSC, there is sufficient space (either in the laydown area outside the NSC or on the roof of the TPS room) for placement of a control station, high voltage power supply, cooling and electrical cabinets, and NDAS-related consumables and tooling to support NDAS testing. Figure 4a2.5-1 provides a plan and section view of the NSC. A list of system interfaces associated with the NSC is provided in Table 9a2.7-4.
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9a2.7-6 Rev. 2 Commissioning, maintenance, and disposal activities associated with the NDAS and performed in the NSC are summarized below.
Commissioning An NDAS may be tested in the NSC prior to installation in an IU cell. The NDAS sub-assemblies will be staged, mounted to the supporting pads in the NSC, and assembled with the support of the facility crane. The assembled NDAS is connected to service utilities such as electrical, control, cooling water, and supply gases inside and outside the NSC. The commissioning activities to be carried out in the NSC may include establishing vacuum, helium leak rate testing, filling the pressure vessel with sulfur hexafluoride (SF6) gas, and beam performance testing.
Maintenance If portions of an NDAS require maintenance or replacement, it may be moved from an IU cell to the NSC. The NDAS is lifted by the IF bridge crane and transferred to the NSC where work can be performed.
Disposal The NSC may also be used to disassemble an NDAS into smaller parts that can fit more easily into containers before sending to an appropriate waste repository.
9a2.7.2.3 Radiological Protection Gamma radiation monitoring of the NSC is provided to allow for safe operation and interlocking of activities in the NSC. The NSC has a directed airflow system to manage residual tritium contamination of NDAS components. This airflow system maintains the capability to interface with the facility heating, ventilation, and air conditioning (HVAC) through radiological ventilation zone 2 exhaust (RVZ2e). A passive tritium sample collector at the interface to RVZ2e provides a record of tritium content entering RVZ2e from the NSC. The NSC provides a real-time tritium monitor at the interface to the RVZ2e to measure real-time tritium content in exhaust gas from NDAS testing sent to RVZ2e.
The NSC shield walls are made from approximately 24-inch (61 centimeter) thick concrete walls with reinforcing carbon steel bars. Additional local shielding, such as water or polycarbonate blocks, may also be installed during testing in the NSC. Implementation of local shielding in the pit, and around an installed NDAS as necessary, provides radiation shielding during NDAS testing. This local shielding functions in conjunction with the shielding provided by the NSC shield walls and door to maintain occupational exposures to neutron and gamma radiation to within ALARA program goals. Table11.1-4 provides radiation areas at the main production facility, and includes dose rates to the IF general area during accelerator testing in the NSC. Calculated dose rates during accelerator operation in the NSC are approximately 8 mrem/hr outside the NSC walls. The annual average neutron flux to the NSC surrounding soil is expected to be less than 100 n/cm2-s.
9a2.7.2.4 Instrumentation and Controls The NSC provides instrumentation and controls to perform testing of an NDAS to verify proper operation before returning to service. Interlocks for safe testing of the NDAS, such as preventing operation of the NDAS while the service cell door is open are provided. A radiation interlock button located inside the NSC prevents or shuts down operation of the NDAS when actuated by personnel in the NSC.

Chapter 9 - Auxiliary Systems Heating, Ventilation, and Air Conditioning Systems SHINE Medical Technologies 9b.1-1 Rev. 1 9b RADIOISOTOPE PRODUCTION FACILITY AUXILIARY SYSTEMS 9b.1 HEATING, VENTILATION, AND AIR CONDITIONING SYSTEMS The heating, ventilation, and air conditioning (HVAC) systems for the main production facility are common to the irradiation facility (IF) and the radioisotope production facility (RPF). The main production facility HVAC systems are described in Section9a2.1.
Chapter 9 - Auxiliary Systems Handling and Storage of Target Solution SHINE Medical Technologies 9b.2-1 Rev. 1 9b.2 HANDLING AND STORAGE OF TARGET SOLUTION 9b.2.1 TARGET SOLUTION LIFECYCLE This section addresses the lifecycle of the target solution from the time that it enters the jurisdiction of the SHINE facility until it is released from such jurisdiction.
Target solution is a low-enriched, uranyl sulfate solution that is prepared by converting solid uranium oxide into the uranyl sulfate solution using the target solution preparation system (TSPS). Low enriched uranium (LEU) is received by the uranium receipt and storage system (URSS) as either uranium metal or uranium oxide. If metal is received, the URSS converts the metal to uranium oxide, as described in Subsection4b.4.2. After preparation, the target solution is held in the target solution preparation tank until it is transferred to the target solution staging system (TSSS) and loaded into the target solution vessel (TSV) from the TSSS for an irradiation cycle. After irradiation is complete, the irradiated target solution is transferred to the molybdenum extraction and purification system (MEPS) where molybdenum is separated from the target.
Following processing in MEPS, the target solution may be delivered to the TSSS for storage or another irradiation cycle, to the radioactive liquid waste storage (RLWS) system for disposal, or to the iodine and xenon purification and packaging (IXP) system for separation of iodine and xenon isotopes as products. At the end of its lifecycle as target solution, the uranyl sulfate solution is transferred to the RLWS. In the RLWS, the uranyl sulfate solution is blended with other waste streams and held in storage until it is ready to be solidified by the radioactive liquid waste immobilization (RLWI) system. Solidified wastes are transferred to the material staging building for preparation for shipment off-site.
The chemical properties of the target solution are described in Subsection4a2.2.1.
Detailed descriptions of the processes involving irradiated and unirradiated special nuclear material (SNM) are provided in Subsection4b.4.1 and Subsection4b.4.2, respectively.
Equipment, application of administrative controls, and the design features involved in the SNM lifecycle are included in this section.
Section12.8 provides a discussion of the physical security of the SNM. Section4b.2 provides a discussion of the shielding requirements associated with irradiated target solution. Section5a2.2 provides a description of the primary closed loop cooling system(PCLS), which is used to remove heat from the TSV and neutron multiplier during irradiation of the target solution.
Chapter13 provides the accident analysis accident analysis of the SHINE facility, including those scenarios related to the storage and handling of target solution. Detailed discussions of radiological considerations related to the handling and storage of target solution are provided in Section11.1.
9b.2.2 RECEIPT AND STORAGE OF UNIRRADIATED SNM The URSS receives, handles, and stores unirradiated uranium. The URSS facilitates the sampling of received SNM and converts uranium metal to uranium oxide prior to its use in TSPS.
Uranium is stored in canisters placed on racks designed for criticality safety. Subsection6b.3.2 provides information on criticality safety controls for receipt and storage of uranium.
A detailed description of the URSS is provided in Subsection4b.4.2.1.
Chapter 9 - Auxiliary Systems Handling and Storage of Target Solution SHINE Medical Technologies 9b.2-2 Rev. 1 9b.2.3 TARGET SOLUTION PREPARATION The TSPS converts uranium oxide into a uranyl sulfate solution for use as a target solution batch or as makeup solution. Uranium is transferred from the URSS and imported into the TSPS glovebox for dispensation into the dissolution tanks. After conversion to uranyl sulfate in the dissolution tank, the uranium solution is pumped to the target solution preparation tank for storage until it is needed for an irradiation cycle or as makeup solution.
A detailed description of the TSPS is provided in Subsection4b.4.2.2.
9b.2.4 TARGET SOLUTION STAGING SYSTEM Target solution batches prepared for irradiation are transferred from the TSPS to the TSSS. The TSSS consists of target solution hold tanks and target solution storage tanks. Target solution hold tanks stage the target solution for transfer into the primary system boundary (PSB). Target solution storage tanks provide additional storage capacity for the facility. Tanks in the TSSS can receive target solution discharged from processes in the hot cells. The target solution may be sampled from each tank.
A detailed description of the TSSS is provided in Subsection4b.4.1.1.
9b.2.5 VACUUM TRANSFER SYSTEM The vacuum transfer system (VTS) provides the transport of radioactive liquids, including target solution, throughout the radioisotope production facility (RPF). The VTS operates by applying vacuum to an intermediary lift tank or directly to a destination tank. The VTS also provides vacuum service to RPF systems.
9b.2.5.1 Design Bases The VTS is designed to:
Prevent inadvertent criticality in accordance with the criticality safety evaluation.
Relieve the system to atmospheric pressure upon actuation of the engineered safety features actuation system (ESFAS) to terminate transfers of target solution.
9b.2.5.2
System Description
The VTS consists of vacuum pumps, a knockout pot, vacuum lift tanks, and associated piping components and instrumentation. Process piping and pipe components are designed to meet the requirements of ASME B31.3, Process Piping (ASME,2013).
VTS transfers liquid by one of the two following distinct methods:
The first method moves liquid in batches via small volume tanks. These tanks are collectively named lift tanks. In the VTS, a vacuum is drawn on the knockout pot by a set of vacuum pumps, which discharge to the process vessel vent system (PVVS) for off-gas treatment. Solution transfers occur by aligning a vacuum lift tank with the knockout pot.
Vacuum is applied to the lift tank, and solution flows from the source tank. Once the vacuum lift tank level setpoint is reached, the lift tank is isolated from the knockout pot
Chapter 9 - Auxiliary Systems Handling and Storage of Target Solution SHINE Medical Technologies 9b.2-3 Rev. 1 and the lift tank is vented to atmosphere. Once pressure is equalized, the solution may be drained, pumped from the lift tank, or transferred to a second stage of lift tanks for additional elevation gain. Liquid transfers using vacuum lift tanks in the RPF are identified in Table9b.2-1.
The second method facilitates solution transfers without using a vacuum lift tank. Vacuum from the knockout pot is applied directly to the selected destination tank, and valves in the pathway between the source tank and destination tank are aligned to allow flow. This method is typical for transfers in the RLWS system, the RLWI system, and between laboratory scale processes that are part of the isotope separation process. Direct liquid transfers between tanks facilitated by VTS are identified in Table9b.2-2.
Two separate vacuum headers are provided based on the liquid being transferred. Tanks designed to contain target solution are provided with vacuum from a separate header than tanks with concentration controls or other tanks or services that are not intended to contain fissile material. The headers are air gapped at the knockout pot as shown in Figure9b.2-1.
The VTS provides an interface for sampling of solution in the target solution hold tanks, target solution storage tanks, RLWS system tanks, and the radioactive drain system (RDS).
The VTS is the only system used to transport SNM between the RPF and IF. A description of the process used to fill the TSV is provided in Subsection4a2.6.1. The VTS is one of the systems used to transport solutions of SNM or byproduct material in the RPF. The other systems used to transport solutions containing SNM or byproduct material in the RPF are TSPS, MEPS, IXP, and the RLWI system, which use pumps to provide the motive force to transport the solutions.
Table9b.2-3 identifies the systems which interface with the VTS.
Figure9b.2-1 provides a process flow diagram of the VTS.
9b.2.5.3 Instrumentation and Controls Temperature of solution in the source tank is monitored prior to a transfer to ensure that the transfer does not induce the solution to flash in the pipe. Level of each vacuum lift tank is also monitored to allow the process integrated control system (PICS) to control each transfer.
Automatic flow shut-off valves and liquid detection instruments are provided in the VTS to prevent solution from entering the knockout pot. On detection of liquid by these instruments, ESFAS actuates valves that act as vacuum breakers on the knockout pot and trips the breakers on the vacuum pumps, terminating solution transfers. The knockout pot drains to favorable geometry tanks in the RLWS system in the event of high-level alarm. ESFAS also trips the vacuum breaking valves and pump on detection of high radiation in radiological ventilation zone1 (RVZ1) or on level detection in the RDS. A detailed description of the ESFAS is provided in Section7.5.
9b.2.5.4 Safety Analysis The VTS is a safety-related system. The VTS structural framework and pipe supports are designed to withstand design basis seismic events. The VTS is classified as Seismic Category I.

9b.2.6 RADIOACTIVE LIQUID WASTE STORAGE Liquid wastes from the isotope production processes may contain SNM. These liquids are drained from the hot cells to the first favorable geometry uranium waste tank in the RLWS system. Once the liquid waste is verified to be below administrative limits, it is transferred to the second uranium waste tank where it is sampled again prior to sending to the liquid waste blending tanks for additional storage time. Target solution batches are disposed of through the RLWS system. Once a batch is designated for disposal, it is transferred to the RLWS system to be blended with other wastes.
A detailed description of the RLWS system is provided in Subsection9b.7.4.
9b.2.7 RADIOACTIVE LIQUID WASTE IMMOBILIZATION Liquid wastes in the RLWS system are solidified by the RLWI system. Liquid wastes in the RLWS system may contain SNM. Solutions are transferred to the RLWI system by the VTS from the RLWS system. In the RLWI system, solution may be [
]PROP/ECI to remove isotopes that impact waste classification (e.g., Sr-90, Cs-137).
Liquids are solidified in drums pre-filled with immobilization agents. The cured waste drums are handled by the solid radioactive waste packaging(SRWP) system upon removal from the RLWI system.

System Interface Description
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-1 Rev. 2 9b.6 COVER GAS CONTROL IN THE RADIOISOTOPE PRODUCTION FACILITY This section discusses radiolytic gas management systems located in the radioisotope production facility (RPF) that manage radioactive gases associated with SHINE facility processes.
9b.6.1 PROCESS VESSEL VENT SYSTEM The process vessel vent system (PVVS) collects and treats the off-gases from processes in the main production facility. The PVVS collects off-gases from each RPF tank containing irradiated solutions, from the vacuum transfer system (VTS) vacuum pump discharge, and periodically from the target solution vessel (TSV) off-gas system (TOGS). The PVVS consists of acid adsorbers, carbon filters, high-efficiency particulate air (HEPA) filters, condensers, reheaters, carbon beds, and blowers which are employed to vent treated gases out of the radiologically controlled area (RCA). A description of system interfaces is provided in Table9b.6-1.
9b.6.1.1 Design Bases The design bases of the PVVS include:
Mitigate radiolytic hydrogen generation in the headspace of RPF tanks and vessels; Capture radioiodine from the off-gas stream; Delay the release of radioactive noble gases in gaseous effluents to the environment; Filter radioactive particulates from the gaseous effluents; Maintain RPF tanks and vessels at a negative pressure; Accept VTS vacuum pump discharge; Accept TOGS pressure relief discharge; Accept purges of TOGS, resulting from either a loss of TOGS capability to mitigate radiolytic hydrogen generation or maintenance requirements; Accept any sweep gases from TOGS used to purge gas analyzer instrumentation; Condition collected off-gas to improve reliability and performance of filtration equipment; and Discharge off-gases to the facility stack.
9b.6.1.2
System Description
The PVVS provides radiolytic hydrogen mitigation capability for the RPF by ventilating the process tanks and vessels. The PVVS also accepts gases discharged from VTS and TOGS.
Flows from VTS and TOGS include vacuum pump discharge, sweep gas from gas analyzer instruments, nitrogen purges, and pressure relief. PVVS blowers upstream of the stack induce flow through the ventilation system. Flow rate requirements for PVVS are constant for nominal ventilation in the RPF but increase when tanks are sparged for mixing, when VTS is operating, or during TOGS transients such as a purge during fill or maintenance, or pressure relief. PVVS equipment is designed for the maximum off-gas flow rate that could require processing at any one time.
The off-gases are processed to remove or delay iodine, noble gases, and radioactive particulates prior to gas being discharged to the facility stack. PVVS blower placement results in the system being maintained at a negative pressure relative to ventilation zone 2. Intakes within ventilation zone 2 are the nominal air source for PVVS. Air flows from the intake, across
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-2 Rev. 2 the tank headspace, to the PVVS conditioning and filtration equipment. Gases pass through condensers, cooled with process chilled water, to remove excess heat and reduce absolute humidity of the off-gas.
Condensate is collected in the PVVS condensate tank within the PVVS hot cell, located within the supercell. Condensate may be returned to the target solution staging system (TSSS) tanks as makeup water or to the radioactive liquid waste storage (RLWS) system for waste processing. An in-line heater, the PVVS reheater, downstream of the condenser heats the off-gas back to ambient temperature to reduce the relative humidity. The off-gas then flows through acid adsorber beds, HEPA filters, and the guard beds to neutralize entrained acid droplets or gases, filter particulates, and capture iodine. The gas flows from the hot cell to a below-grade, shielded vault, passing through a series of delay beds packed with carbon to delay the release of fission product noble gases such as xenon and krypton. The eight delay beds are organized into three groups as shown in Figure9b.6-1. Group 1 includes Delay Beds 1 and 2. Group2 includes Delay Beds 3, 4, and 5. Group 3 includes Delay Beds 6, 7, and 8. A final set of HEPA filters removes any entrained carbon fines upstream of the blowers, and the treated gases are discharged to the facility stack.
In the event PVVS flow drops below the minimum flow rate of 5.0standard cubic feet per minute, the engineered safety features actuation system (ESFAS) automatically initiates an RPF Nitrogen Purge. This results in the nitrogen purge system (N2PS) providing nitrogen flow to the RPF tanks to mitigate hydrogen generation. Upon actuation of the N2PS, the RPF header valves actuate open, the isolation valves at the PVVS north and south header valves actuate closed, and the PVVS isolation valve at the radioactive liquid waste immobilization (RLWI) interface actuates closed to prevent nitrogen backflow. During the nitrogen purge, the PVVS equipment and piping continues to provide the flow path for the off-gas through the RPF.
Safety-related bypasses are provided around filtration equipment in the hot cell that could contribute to a blocked pathway and an alternate, safety-related exhaust point to the roof is actuated open. The branch to the alternate release point is upstream of the PVVS blowers.
Fire protection is provided for the guard beds and delay beds. Temperature instrumentation and carbon monoxide detection are used to monitor for oxidation. The beds may be isolated or purged with nitrogen to smother the reaction. Additionally, operators can attempt to increase the system flow rate to increase convective cooling. The ESFAS automatically isolates affected delay bed groups when carbon monoxide concentrations in the effluent gas exceed 50 ppm.
Principal components of the PVVS are identified in Table9b.6-2.
A process flow diagram of the PVVS is provided in Figure9b.6-1.
9b.6.1.3 Operational Analysis and Safety Function The PVVS provides confinement of fission products to prevent release of radioactive material.
The PVVS maintains hydrogen concentrations below the lower flammability limit(LFL) to preclude a hydrogen deflagration or detonation, as discussed in Subsection9b.6.1.3.1. The PVVS passively reduces the concentration of radionuclides in the gaseous effluent to the facility stack, including during postulated transients, as discussed in Subsection9b.6.1.3.2.
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-3 Rev. 2 In addition to the above:
Safety-related components in the PVVS remain functional during normal conditions, and during and following design basis events.
Valves in PVVS fail to their designated safe position on loss of power.
Redundant isolation capabilities are provided at confinement boundaries.
Redundant isolation is provided for safety-related actuations.
An open flow path through PVVS remains available during normal conditions, and during and following design basis events.
PVVS components installed over, attached to, or adjacent to safety-related equipment are designed so as not to fail in such a way that is detrimental to the operation of safety-related equipment.
9b.6.1.3.1 Hydrogen Mitigation Hydrogen is generated by radiolysis in the target solution and the byproduct solutions contained in the process tanks of the RPF, excluding the target solution preparation system (TSPS). Build-up of the hydrogen could result in a detonation or deflagration if the concentration exceeds the LFL. PVVS ventilates the RPF tanks to prevent build-up of hydrogen above LFL.
In the event of failure of the PVVS discharge blowers, the PVVS filtration equipment continues to process the sweep gas provided from N2PS through the tanks throughout the RPF. The quantity of sweep gas supplied is sufficient to maintain hydrogen concentration below the LFL.
Under normal operation, the required quantity of sweep gas is induced into the process tanks by the suction from the PVVS blowers. In the event of failure of the PVVS blowers, the N2PS will provide the sweep gas flow, thereby maintaining the sweep gas component of the total PVVS flow.
9b.6.1.3.2 Iodine and Noble Gas Abatement The systems and processes in the RPF release radioactive isotopes of iodine and noble gases from the target solution and from byproduct solutions. Gases discharged by TOGS from the primary system boundary, which contain noble gases and iodine, are also processed by the PVVS. The off-gas may also contain radioactive particulates such as cesium. HEPA filters are used to remove entrained particulates from the air flow. Carbon filters are used to capture iodine and carbon beds are employed to delay the release of xenon and krypton isotopes. The design ensures that 10 CFR 20 limits are met.
9b.6.1.4 Instrumentation and Control Safety-related PVVS instrumentation has redundant channels and provides output to ESFAS.
Nonsafety-related PVVS instrumentation provides output signals to the process integrated control system (PICS).
Temperature instrumentation is used to monitor the performance of the condensers, heaters, and acid adsorbers as well as the guard beds and delay beds.
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-4 Rev. 2 Redundant gas analyzers monitor the hydrogen concentration upstream of the guard beds. The gas analyzers are used to monitor the operation of the delay beds and to monitor carbon monoxide concentrations in the bed effluent.
Flow instrumentation is used to monitor the flow rate of air from ventilation zone 2 into the RPF tanks and vessels ventilated by PVVS. The PICS alerts operators on low flow. Flow instrumentation is used to monitor the flow rate of air from the RPF tanks and vessels to the condensers. The system is designed to maintain this flow rate above the minimum required to maintain hydrogen levels below the LFL.
Pressure instrumentation is provided to monitor performance of the HEPA filters.
9b.6.1.5 Radiological Protection and Criticality Control PVVS processes are performed within the production facility biological shield (PFBS) hot cells and below-grade vaults, which supports compliance with the as low as reasonably achievable (ALARA) objectives and 10 CFR 20 dose limits. Section11.1 provides a description of the radiation protection program, and Section4b.2 provides a detailed description of the PFBS.
There are no credible mechanisms by which to create a criticality hazard in the PVVS. As described in Subsection6b.3.1.6, there are no identified criticality safety controls for the PVVS.

This includes limiting conditions for operation, setpoints, design features, and means for accomplishing surveillances. In addition, significant material is also applicable to, and may be used for the bases that are described in the technical specifications.
9b.6.2 NITROGEN PURGE SYSTEM The N2PS provides a backup supply of sweep gas to each irradiation unit (IU) and to all tanks normally ventilated by the PVVS during a loss of normal power or loss of normal sweep gas flow. The off-gas resulting from the nitrogen purge is treated by passive PVVS filtration equipment prior to being discharged to the stack, as discussed in Subsection9b.6.1.2. The nitrogen supply pressure is regulated to overcome the pressure drop through pipe fittings, PVVS filtration components, and the facility stack. The N2PS is safety-related and Seismic Category I. A description of system interfaces is provided in Table9b.6-3.
9b.6.2.1 Design Bases The design bases of the N2PS include:
Ensure safe shutdown by preventing detonations or deflagrations from potential hydrogen accumulation in the IUs and RPF processes during deviations from normal conditions; and Remain functional during and following design basis events.
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-5 Rev. 2 9b.6.2.2
System Description
N2PS provides back-up sweep gas flow in the form of stored pressurized nitrogen gas.
Downstream pressure is controlled with self-regulating pressure reducing valves with overpressure protection by pressure relief valves. On actuation of the N2PS, nitrogen flows through the irradiation facility (IF) and RPF equipment to ensure the hydrogen concentration is below the LFL. The nitrogen purge flows through the normal PVVS path and filtration equipment, including the delay beds. After exiting the delay beds in PVVS, the nitrogen purge is diverted to a safety-related alternate vent path in case of a downstream blockage. Valves configured to fail open allow the diversion to the alternate vent path. After actuation of the N2PS, the pressurized storage tubes can be refilled by truck deliveries.
A process flow diagram of the N2PS is provided in Figure9b.6-2.
Purge of an IU Upon loss of normal power as determined by the engineered safety features actuation system (ESFAS) and after a delay or upon loss of normal sweep gas flow in the IU as determined by the TSV reactivity protection system (TRPS), solenoid valves on the nitrogen discharge manifold actuate open, releasing nitrogen into the IU cell supply header. Upon loss of sweep gas flow in any IU cell, nitrogen solenoid isolation valves for the given cell actuate open releasing nitrogen purge gas into the TSV dump tank, and valves in the TOGS actuate open to allow the nitrogen purge gas to flow to the PVVS. The nitrogen purge gas flows through the TSV dump tank, TSV, and TOGS equipment before discharging into PVVS. A flow switch provides indication that nitrogen is flowing to the IU cell. A detailed discussion of the IU Cell Nitrogen Purge is provided in Section7.4.
Purge of RPF Equipment Upon loss of normal power or loss of normal sweep gas flow through PVVS, as determined by the ESFAS, solenoid valves on the ventilation zone 2 air supply to PVVS fail closed and isolate the sweep gas air flow to the RPF tanks. At the same time, solenoid valves on the nitrogen discharge manifold actuate open, releasing nitrogen into the RPF distribution piping. The nitrogen flows through the RPF equipment in parallel before discharging into PVVS. A flow switch provides indication that nitrogen is flowing to the RPF distribution piping.
Processes that receive ventilation air from the PVVS during normal conditions are also ventilated by N2PS during deviations from normal operation. In the RPF, the N2PS ventilates tanks in the TSSS, RLWS system, radioactive drain system (RDS), molybdenum extraction and purification system (MEPS), iodine and xenon purification and packaging (IXP) system, and VTS. A detailed discussion of the RPF Nitrogen Purge is provided in Section7.5.
9b.6.2.3 Operational Analysis and Safety Function In the event of a loss of normal power, loss of sweep gas flow through PVVS, or loss of sweep gas flow through any TOGS, the N2PS controls the buildup of hydrogen which is released into the primary system boundary and tanks or other volumes which contain fission products to ensure that the system and confinement boundaries are maintained.
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-6 Rev. 2 The N2PS provides back-up sweep gas in the form of stored pressurized nitrogen gas.
Downstream pressure is controlled with self-regulating pressure reducing valves with overpressure protection provided by pressure relief valves. Tanks containing irradiated target solution in the RPF are supplied with a self-regulating pressure reducing valve with overpressure protection provided by a pressure relief valve. TSV dump tanks are supplied with a self-regulating pressure reducing valve. N2PS piping, valves, and in-line components are designed to ASME B31.3, Process Piping (ASME,2013).
The high-pressure nitrogen gas storage is contained in integrally forged pressure vessels (i.e.,high-pressure nitrogen gas tubes) designed to meet the requirements of ASME Boiler and Pressure Vessel Code(BPVC),Section VIII, Rules for Construction of Pressure Vessels (ASME, 2010). The tubes and associated piping, manual isolation valves, high point vents, low point drains, self-regulating pressure reducing valves, relief valves, check valves, and pressure instrumentation for the supply system are located in the N2PS structure, an above-grade reinforced concrete structure adjacent to the main production facility. The N2PS structure and equipment are designed to remain functional during and following a seismic event. Additionally, the N2PS structure is designed to withstand the impact of tornado missiles.
The tubes are manifolded so they will act in unison and have a common remote fill connection to allow refill by tanker truck delivery. One redundant high-pressure nitrogen gas tube provides service in the event of the loss of a tube or failure of the associated valves upstream of the common manifold. Each high-pressure nitrogen gas tube and the downstream piping and equipment is protected from overpressure by relief valves discharging to atmosphere above the roof of the structure, through a nonsafety-related vent path.
The N2PS is sized to provide three days of sweep gas flow to tanks containing irradiated target solution in the RPF during a loss of normal power or a loss sweep gas flow. The N2PS also provides three days of sweep gas flow to each TSV dump tank.
9b.6.2.4 Instrumentation and Control The N2PS includes pressure instrumentation to monitor the function of the self-regulating pressure reducing valves. The nitrogen tube pressure, tube discharge pressures, pressure to the IU cells, and pressure to the RPF tanks are monitored. The pressure instrument output is provided to PICS.
The N2PS includes flow switches on the piping to the IU cells and RPF tanks to provide indication of normal operation when the purge is actuated. The flow switch status is provided to PICS.
N2PS solenoid valves include valve position indication. The position status for each valve is provided to TRPS if it serves the IU cells or to ESFAS if it serves the RPF tanks.
Oxygen sensors are provided in locations near N2PS equipment. The oxygen instruments alert operators locally of an asphyxiation hazard in the event of a nitrogen leak.
TRPS actuates the N2PS purge of the affected IU on loss of normal power to an IU cell after a delay or on loss of flow in TOGS.
Chapter 9 - Auxiliary Systems Cover Gas Control in the Radioisotope Production Facility SHINE Medical Technologies 9b.6-7 Rev. 2 ESFAS actuates the N2PS purge of the RPF tanks on loss of normal power to the PVVS or on loss of flow in PVVS.
9b.6.2.5 Radiological Protection and Criticality Control The N2PS contains no special nuclear material or any other radioactive material. Therefore, the N2PS does not require shielding nor is criticality safety considered in the design.
9b.6.2.6 Technical Specifications Certain material in this subsection provides information that is used in the technical specifications. This includes limiting conditions for operation, setpoints, design features, and means for accomplishing surveillances. In addition, significant material is also applicable to, and may be used for the bases that are described in the technical specifications.

9b.7.2 MATERIAL HANDLING SYSTEM 9b.7.2.1 Design Bases The material handling system (MHS) includes overhead cranes and hoists that are used to move or manipulate radioactive material within the radiologically controlled area (RCA).
Irradiation Facility Overhead Crane The irradiation facility (IF) crane is designed to meet the applicable requirements of American Society of Mechanical Engineers(ASME) B30.2, Overhead and Gantry Cranes (Top Running Bridge, Single or Multiple Girder, Top Running Trolley Hoist) (ASME,2011a); Crane
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-3 Rev. 3 Manufacturers Association of America(CMAA)70, Specifications for Top Running Bridge &
Gantry Type Multiple Girder Electric Overhead Traveling Cranes(CMAA,2004); and ASMENOG-1, Rules for Construction of Overhead and Gantry Cranes (Top Running Bridge, Multiple Girder) (AMSE,2015).
The IF overhead crane is designed to the following criteria:
Meet seismic requirements and prevent failures of the crane that could damage safety-related equipment such that the equipment would be prevented from performing its safety function.
Meet the single-failure-proof design criteria and construction of ASME NOG-1, TypeI cranes and be designed to perform as a Service Level B - Light Service crane as described in CMAA70.
Secure its load in place upon a loss of power and any fault condition. The hoisting machinery and wire rope reeving system, in addition to other affected components, is designed to withstand the most severe potential overload, including two-blocking and load hang-up.
Radioisotope Production Facility Overhead Crane The radioisotope production facility (RPF) overhead crane is designed to meet the applicable requirements of ASME B30.2 (ASME, 2011a), CMAA70 (CMAA,2004), and ASME NOG-1 (ASME,2015).

Remain in place with or without a load during a seismic event.
9b.7.2.2
System Description
Irradiation Facility Overhead Crane The IF overhead crane is a 40-ton, double girder, bridge style crane designed for the handling of shield cover plugs and equipment such as neutron drivers and process skids inside the IF. The IF overhead crane is designed to span the width of the IF and travel the length of the IF.
The use of a single-failure-proof crane with rigging and procedures that implement the requirements of NUREG-0612, Control of Heavy Loads at Nuclear Power Plants (USNRC,1980) assures that the potential for a heavy load drop is extremely small, and therefore, analysis of the potential effects of heavy load drops are not required.
The IF overhead crane is designed and constructed such that it will remain in place and support the critical load during and after an aircraft impact but is not required to be operational after this
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-4 Rev. 3 event. Single failure-proof features are included such that any credible failure of a single component will not result in the loss of capability to stop and hold the critical load.
Radioisotope Production Facility Overhead Crane The RPF overhead crane is a 15-ton, double girder, bridge style crane designed for the handling of shield cover plugs and equipment in the RPF. The RPF overhead crane is designed to span the width of the RPF and travel the length of the RPF.
The RPF overhead crane employs the use of mechanical stops, electrical-interlocks, and predetermined safe load paths to minimize the movement of loads in proximity to redundant or dual safe shutdown equipment. These safeguards ensures that off-normal load events from loads containing radioactive materials or safety-related SSCs that are beneath, or directly adjacent to a potential travel load path of the RPF overhead crane, could not result in the complete loss of a safe shutdown function or the release of radioactivity in excess of 10 CFR 20 limits.
The RPF overhead crane is designed and constructed following the seismic requirements for an ASME NOG-1, TypeII crane so that it will remain in place with or without a load during a design basis earthquake. The crane is not required to support the critical load nor remain operational during and after such an event.
9b.7.2.3 Operational Analysis and Safety Function The IF overhead crane removes irradiation unit(IU) cell plugs, the target solution vessel (TSV) off-gas system (TOGS) cell plugs, primary cooling room plugs, and neutron driver transport to and from IU cells and the neutron driver assembly system (NDAS) service cell. The IF overhead crane is used for lifting, repositioning, and landing operations associated with major components of the subcritical assembly system (SCAS), the primary closed loop cooling system (PCLS), the TOGS, and the tritium purification system (TPS) as well as various planned maintenance activities throughout the IF.
The RPF overhead crane is utilized for lifts including the removal of tank vault, valve pit, and pipe trench plugs, removal of carbon delay bed vault plugs, supercell slave manipulator replacements, and the removal of column waste drums and post cooldown shielding/packaging. The RPF overhead crane is used for various planned maintenance activities. In addition, the crane performs lifting of empty tanks in the RPF, immobilized waste drums and the associated shielding/packaging hardware, and other major components within the RPF.
The IF and RPF overhead cranes are inspected, tested, and maintained in accordance with ASME B30.2 (ASME,2011a). The inspection requirements reduce the probability of a load drop that could result in a release of radioactive materials or damage to essential safe shutdown equipment that could cause unacceptable radiation exposures. Inspection and testing of special lifting devices are performed in accordance with American National Standards Institute (ANSI)N14.6, Radioactive Materials - Special Lifting Devices for Shipping Containers Weighing 10,000Pounds (4500 kg) or More (ANSI,1993). Inspection and testing of lifting devices not specially designed are in accordance with ASME B30.9, Slings (ASME,2018).
With respect to the SHINE facility, a heavy load is defined as a load that, if dropped, may cause radiological consequences that challenge 10 CFR 20 limits. For cranes operating in the vicinity of

Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-5 Rev. 3 safety-related SSCs, SHINE has applied guidance from Section 5.1.1 of NUREG-0612 (USNRC, 1980) relative to the crane design as follows:
1.
Safe load paths will be defined for the movement of heavy loads; deviations from the defined load paths will require written procedures approved by site safety personnel.
2.
Procedures will be developed to cover load handling operations for heavy loads.
Procedures will include the identification of required equipment, inspections, and acceptance criteria required before movement of loads; the steps and proper sequence to be followed in handling the load; the defined safe load path and other special precautions.
3.
Crane operators will be trained, qualified, and conduct themselves in accordance with Chapter 2-3 of ASME B30.2.
4.
Special lifting devices used in the vicinity of safety-related SSCs will satisfy the guidelines of ANSI N14.6.
5Property "ANSI code" (as page type) with input value "ANSI N14.6.</br></br>5" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process..
Lifting devices that are not specially designed will be installed and used in accordance with the guidelines of ASME B30.9.
6.
Tests and inspections will be performed prior to use where it is not practical to meet the frequencies of ASME B30.2 for periodic inspection and testing, or where frequency of crane use is less than the specified inspection and test frequency.
7.
The crane will be designed to meet applicable criteria and guidelines of ASMEB30.2 and CMAA70.
The IF and RPF overhead cranes are nonsafety-related.
9b.7.2.4 Instrumentation and Control The IF and RPF overhead crane control systems provide for separate operation of the hoist, bridge, and trolley motions. Overhead crane control switches for the main hoists, bridges, and trolleys are radio controlled with backup pendant controllers. Both IF and RPF overhead crane systems allow all motions to be controlled from the radio transmitter as well as a backup pendant pushbutton station. The controls for both the IF and RPF overhead cranes are interlocked so only one station (radio or pendant) can be operated at a time. The IF and RPF overhead crane controls are such that the release of the controller or loss of power automatically stops the cranes motion and sets the brakes.

Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-6 Rev. 3 Reduce radiation exposure during operation in accordance with applicable guideline exposures set forth in 10 CFR 20.
The RLWI system piping is designed and constructed in accordance with ASME B31.3, Process Piping(ASME,2013). Nonsafety-related components within the RLWI system are designed to standards satisfying system operation.
9b.7.3.2
System Description
The RLWI system solidifies blended liquid waste to a form suitable for shipping and disposal. The RLWI system removes selected isotopes, as needed, from the blended liquid waste and then immobilizes the wastes for ultimate disposal. The headspace cover gas in the immobilization feed tank is swept by the PVVS.
The blended liquid waste sources and radionuclide and uranium concentrations are described in Subsection9b.7.4.
The immobilization feed tank is filled from the liquid waste blending tanks on a batch basis by vacuum suction applied to the immobilization feed tank from the vacuum transfer system(VTS).
Positive displacement pumps transfer the contents of the immobilization feed tank [
]PROP/ECI, and meter the tank contents to a disposable waste drum.
The waste drums are prefilled with measured amounts of dry, powdered solidification agent in accordance with the process control program(PCP). The prefilled drum is transferred into an enclosure for contamination control. The radiological ventilation zone1 exhaust subsystem (RVZ1e) equipment processes air from the enclosure through a high efficiency particulate air (HEPA) and carbon filter before discharging to the facility stack. Transfer of the prefilled waste drum inside the enclosure is by remote handling equipment and positioners.
The liquid waste drum is filled with blended liquid waste and mixed. Subsequent to fill and mixing, the fill and vent ports are disengaged. The drum is then remotely transferred to a curing station where the mixed contents of the waste drum hardens prior to removal from the enclosure. The cured drum is remotely transferred into a shielded cask and transported to the material staging building for further radiological decay, as needed, prior to shipment to a licensed disposal facility.
Remote sampling for waste characterization is performed in the RLWS prior to solidification activities. Radiation measurements are performed on the solidified waste drum prior to shipment in the material staging building to verify it meets shipping dose rate requirements.
Table9b.7-1 identifies the systems which interface with the RLWI system. Figure9b.7-1 provides a process flow diagram of the RLWI system.
9b.7.3.3 Operational Analysis and Safety Function Liquid waste solidification is performed in accordance with a PCP. The RLWI system is sized to process approximately double the routine liquid waste generation rate from the RPF.
The maximum level in the immobilization feed tank is limited to a predetermined level below the cover gas supply and vent piping. The system is provided with the ability to drain unprocessed
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-7 Rev. 3 liquid waste back to the RLWS, if necessary, for corrective maintenance access to the RLWI equipment.
The RLWI system valves and dampers fail in the safe position on loss of power.
Table11.2-5 provides the waste methodology for consolidated liquids.
The RLWI system is designed to limit exposure to individuals by ensuring compliance with the applicable requirements of 10 CFR 20. The immobilization feed tank, liquid waste drum fill pumps, and valves are located in a shielded enclosure. Selective isotope removal and waste drum filling and mixing are also performed within the shielded enclosure. Piping that contains radioactive and potentially radioactive materials is routed through shielded pipe chases to limit the exposure of individuals to radiation.
Section11.1 provides a description of the radiation protection program, and Section4b.2 provides a detailed description of the PFBS.
Piping and components connected to, installed over, or installed adjacent to safety-related SSCs are designed to meet seismic requirements because its failure could damage safety-related equipment such that the equipment would be prevented from performing its safety function.
The safety function of the RLWI system is to prevent inadvertent criticality through design of equipment in accordance with the criticality safety evaluation. A description of provisions for criticality control in the RLWI system is provided in Subsection6b.3.2.9.
9b.7.3.4 Instrumentation and Controls Valve position indicators and temperature, flow, level, and pressure instrumentation provide remote indication of the operating state of the RLWI. Output of valve position indicators and other instrumentation is provided to the remotely-located PICS.
9b.7.3.5 Technical Specifications There are no technical specifications associated with RLWI.
9b.7.4 RADIOACTIVE LIQUID WASTE STORAGE SYSTEM 9b.7.4.1 Design Bases The design bases of the RLWS system include:
Collect liquid radioactive wastes from the MEPS, IXP, VTS, PVVS and non-routine operations such as decontamination flushes.
Blend collected liquid radioactive wastes for feed to the RLWI system.
Provide holdup time for radioactive decay of isotopes in the liquid waste.
Allow remote sampling of the stored liquid waste.
Control radioactive liquid waste solution pH to preclude precipitation of uranium and potential criticality.

Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-8 Rev. 3 9b.7.4.2
System Description
The RLWS system collects, stores, blends, conditions, and meters liquid wastes for processing by the RLWI for solidification. Included in the blended liquid wastes is PVVS condensate which can also be recycled through the target solution staging system (TSSS) to minimize waste generation. The RLWS system can also transfer liquid via a normally removed pipe spool to a target solution storage tank for sampling and verification against target solution parameters. The headspace in each RLWS system tank is swept with air by the PVVS or by the nitrogen purge system (N2PS) to remove the potential accumulation of radiolytically generated hydrogen gas.
Laboratory waste is preconditioned and manually processed separately from the RLWS system.
Liquid waste collected, blended, and stored by the RLWS system includes:
Uranium liquid waste, with uranium concentrations potentially exceeding 25 gU/l. This waste is located in the uranium liquid waste tanks.
Radioactive liquid waste, with negligible uranium concentration with respect to criticality safety (<1gU/l). This waste is stored in the liquid waste collection tanks.
Blended liquid waste, with low uranium concentrations (< 25 gU/l). Blended waste may originate from uranium liquid waste, radioactive liquid waste, or any combination of the two.
Uranium liquid waste tanks are geometrically favorable annular tanks similar in design to those used in TSSS. These tanks include two redundant overflow lines which drain to the radioactive drain system(RDS) in the event of an overfill. The uranium liquid waste tanks are connected in series to ensure high concentration uranium-bearing waste (greater than 25 gU/l) is not inadvertently transferred to the non-geometrically favorable liquid waste blending tanks.
The uranium liquid waste tanks are configured to operate in series, with the first tank receiving wastes from the following sources:
Mo-99 extraction column washes Iodine-131(I-131) recovery column washes Spent target solution Solution in radioactive drain sump tanks Solution in VTS knockout pot Decontamination liquid waste PVVS condensate tank Solution from the second uranium liquid waste tank via gravity drain from the uranium liquid waste lift tank The remaining liquid wastes are collected in four liquid waste collection tanks designed and sized to maximize storage capacity. The liquid waste collection tanks are configured to receive wastes from the following sources:

Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-9 Rev. 3 Process liquid wastes determined by sampling to be less than 25gU/l are consolidated into the eight liquid waste blending tanks. The liquid waste blending tanks are configured to receive wastes from the following sources:
Second uranium liquid waste tank PVVS condensate tank Liquid waste collection tanks Uranium liquid waste is combined with the radioactive liquid waste and/or PVVS condensate in the liquid waste blending tanks for homogeneous radionuclide and uranium concentrations in the RLWI system feed.
The tanks are sized to maximize decay time thereby minimizing dose rates from the immobilized waste product. Each uranium liquid waste tank has a minimum nominal capacity of
[ ]PROP/ECI, and each of the liquid waste collection tanks and liquid waste blending tanks has a minimum nominal capacity of 600gallons.
The RLWS system piping is designed and constructed in accordance with ASME B31.3, Process Piping(ASME,2013).
Table11.2-6 provides the chemical composition and radiological properties of liquid waste streams.
Table9b.7-2 identifies the systems which interface with the RLWS system. Figure9b.7-2, Figure9b.7-3, and Figure9b.7-4 provide process flow diagrams of the RLWS system.
9b.7.4.3 Operational Analysis and Safety Function Solenoid valves isolating radioactive liquid flow paths fail to the normally isolated positions.
Solenoid valves isolating the sweep gas flow path fail to the normally aligned flow from air to the PVVS vent header. Operators align the RLWS tank inlets and outlets based on procedures using information from the position indicators and instrumentation.
The RLWS system tanks, valves, and piping are located in shielded tank vaults, valve pits, and pipe trenches within the RPF. Section11.1 provides a description of the radiation protection program, and Section4b.2 provides a detailed description of the PFBS.
Sampling of RLWS system tank contents for pH verifies that waste solution acidity is maintained or is adjusted as necessary. Solution composition can be adjusted via the reagent addition line.
Sampling of waste tanks is performed by vacuum lift to a hot cell, where samples are remotely obtained.
Following a period of decay to reduce dose rates, waste is transferred from the liquid waste blending tanks to the RLWI system immobilization feed tank. Subsection9b.7.3 provides a detailed discussion of the RLWI system.

9b.7.5 SOLID RADIOACTIVE WASTE PACKAGING SYSTEM 9b.7.5.1 Design Bases The design bases function of the solid radioactive waste packaging (SRWP) system is to collect, segregate, and stage for shipment, solid radioactive wastes from the IF and RPF in accordance with the radioactive waste management program.
9b.7.5.2
System Description
The SRWP system consists of equipment designed and specified to collect and package solid radioactive waste from systems throughout the IF and RPF without limiting the normal operation or availability of the facilities. Solid waste may include dry active waste (DAW), spent ion exchange resin, and filters and filtration media. The SRWP system also inventories materials entering and exiting the facility structure storage bore holes as the supercell imports and exports them.
Table11.2-1 includes a summary of the estimated annual waste stream and Table11.1-10 includes a description of radioactive sources. Tables11.2-2 through 11.2-4 present the waste methodology associated with the disposal of neutron drivers, spent columns, and process glassware, respectively.
Table9b.7-3 identifies the systems which interface with the SWRP system.
9b.7.5.3 Operational Analysis and Safety Function Solid radioactive waste is collected in segregated containers. Containers may be sorted for potentially non-contaminated waste. Contaminated waste is sealed, labeled, and transported to the material staging building for characterization, documentation, and staging for shipment. Solid wastes potentially having high levels of radioactivity are collected and transported to the material staging building in shielded casks.
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-11 Rev. 3 Used, activated NDAS units are disassembled prior to transport to the material staging building or storage in storage bore holes. Disassembly minimizes the waste volume shipped for ultimate disposal.
Separation columns used in the processes contained within the supercell are stored on supercell storage racks for a minimum of 14 days following their use. Following decay on storage racks, columns are transferred to column waste drums imported by the supercell. The column waste drums are exported and transferred to the drum storage bore holes. Following extended decay, column waste drums are removed from the bore holes by the supercell.
Depending on weight, solid waste may need to be transferred to the material staging building using forklifts or other lifting devices. Once in the material staging building, solid wastes may be held for decay. Waste is characterized and staged for shipment in the material staging building.
Waste is handled and shipped off site in accordance with the radioactive waste management program, described in Section11.2.
SRWP system operations are performed in accordance with the requirements of the radiation protection program, described in Section11.1.
No nuclear criticality safety requirements are identified for the SRWP system. Nuclear criticality safety is controlled in upstream interfacing systems, where appropriate.
The SRWP system is nonsafety-related.

9b.7.6 RADIOACTIVE DRAIN SYSTEM 9b.7.6.1 Design Bases The design bases of the RDS include:
Collect liquids leaked from tanks, piping, or other components which require favorable geometry for collection and storage.
Collect liquids resulting from the overflow of the target solution storage tanks, target solution hold tanks, and uranium liquid waste tanks.
Provide overpressure protection for the extraction cells and IXP cells of the supercell, as the RDS forms an open pathway through the RDS tanks to the PVVS.
Allows a representative sample of the contents of the RDS sump tanks to be obtained.
Provide a minimum collection volume equal to the maximum liquid volume of one annular tank.
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-12 Rev. 3 9b.7.6.2
System Description
The RDS consists of drip pans with drain lines, tank overflow lines, collection tanks and instrumentation to alert operators of system status. The RDS includes drip pans located beneath the extraction and IXP hot cells, favorable geometry tanks, and piping for systems that normally contain high concentration (> 25 gU/l) fissile solution. The RDS also collects overflow from target solution and uranium waste tanks. The RDS consists of two favorable geometry tanks (annular tanks) that collect leakage from postulated sources. The leakage and overflow are connected by piping that is substantially located within the basemat of the RPF as well as in the RPF pipe trench. Gravity provides the motive force between the various drip pans and the RDS tanks. No valves are installed between the potential collection source and the collection tanks.
Table9b.7-4 identifies the systems which interface with the RDS.
Figure9b.7-5 provides a process flow diagram for the RDS.
9b.7.6.3 Operational Analysis and Safety Function The RDS includes two sump tanks, each sized to accept the largest volume of liquid containing SNM that is postulated to leak from a favorable geometry tank. The largest volume of liquid containing SNM postulated to leak into the RDS system is the volume of the largest favorable geometry tank, assuming the tank is filled to the overflow line. The inclusion of two RDS tanks provides operational margin.
The RDS sump tanks are connected to the target solution storage tanks, target solution hold tanks, and uranium liquid waste tanks. Additionally, the sump tanks are connected to drip pans in vaults containing annular tanks, drip pans in valve pits servicing annular tanks, drip pans in the main pipe trench, and drip pans in the extraction and IXP hot cells. Redundant overflows to a common RDS header are provided for each annular tank. The RDS is not used in any normal operating conditions. Instrumentation is provided to alert operators of the presence of liquid in the various drip pans and of liquid level in the RDS sump tanks. If liquid is detected in the drip pans or sump tanks, contingency actions may be performed by using systems other than the RDS.
Contents of the RDS tanks are sampled and transferred by the VTS to the appropriate location.
Characterization of the sample is performed by the quality control and analytical testing laboratories (LABS).
The RDS needs to remain open for drainage of fissile-containing liquids (for criticality safety),
while also not compromising the integrity of the confinement barrier. Fluids are contained within appropriate process piping and vessels, and the system is vented to the PVVS.
Piping that contains potentially-radiological material is routed through shielded pipe chases to limit the exposure of radiation to personnel. The RDS tanks are shielded by a tank vault, which is a part of the PFBS. The PFBS shielding requirements are described in Section4b.2.
RDS operations are performed in accordance with the requirements of the radiation protection program, described in Section11.1.
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-13 Rev. 3 The RDS prevents inadvertent criticality through inherently-safe geometrical design of sump, tanks, drain lines, and in-line components that may handle fissile material. A description of provisions for criticality control in the RDS is provided in Subsection6b.3.2.8.
The RDS is a Seismic Category I, safety-related system.
9b.7.6.4 Instrumentation and Control The RDS is designed as a passive system, and as such does not use any controls.
The RDS provides liquid detection signals to the engineered safety features actuation system (ESFAS), as described in Subsection7.5.4.
Nonsafety-related monitoring and control is provided by PICS, as described in Subsection7.3.1.

9b.7.7.2
System Description
The FPWS provides a potable water supply to the SHINE facility and is connected to the City of Janesville water supply. The boundaries of the FPWS include the components from the City of Janesville water main to the fixtures in each of the buildings on the SHINE facility. The fixtures are part of the facility sanitary drain system (FSDS), described in Subsection9b.7.9. The FPWS ends at the backflow prevention device interfacing with both the facility demineralized water system (FDWS) and facility heating water system (FHWS). The FPWS does not supply water to the facility fire detection and suppression system (FFPS) or any firefighting equipment.
9b.7.7.3 Operational Analysis and Safety Function Potable water is distributed throughout the SHINE facility through a subgrade piping network.
The FPWS site main connects to SHINE facility building mains, which include the main production facility (outside the RCA), the storage building, and the resource building. The FPWS protects the public water system from contamination due to backflow of contaminants through the water service connection into the public water system using backflow prevention devices.
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-14 Rev. 3 Shielding and radiological protection is not required for the FPWS and the FPWS contains no SNM.
The FPWS is nonsafety-related.

9b.7.7.5 Technical Specifications There are no technical specification parameters associated with the FPWS.
9b.7.8 FACILITY NITROGEN HANDLING SYSTEM 9b.7.8.1 Design Bases The facility nitrogen handling system (FNHS) is designed to supply liquid and compressed gaseous nitrogen to systems inside the RCA. The FNHS gaseous piping is designed, constructed, and tested in accordance with the ASME B31.9, Building Services Piping (ASME, 2011b). The FNHS liquid nitrogen piping is designed, constructed, and tested in accordance with ASME B31.3, Process Piping(ASME,2013). The FNHS vaporizers, receivers, and bulk liquid nitrogen tanks are designed, constructed, and tested to the ASME Boiler and Pressure Vessel Code,Section VIII, Rules for Construction of Pressure Vessels(ASME,2010). The balance of the equipment included in the FNHS is commercially available and is designed to standards satisfying the system operation.
The design basis of the FNHS includes:
Provide nitrogen gas at the pressures and flow rates to operate sampling equipment in the RLWS system, the RDS, the TSSS, the MEPS, and the target solution preparation system (TSPS).
Provide nitrogen gas for sparging and mixing of tanks in the RLWS, the TSSS, the MEPS, the RDS, and the IXP system.
Provide liquid and gaseous nitrogen to the TPS. Gaseous nitrogen is used by the TPS to operate pneumatic equipment. Liquid nitrogen is supplied to the TPS cryopumps and the thermal cycling absorption process (TCAP) isotope separation columns.
Provide liquid nitrogen in dewars to the IXP system and the instrument laboratory for equipment cooling.
Provide nitrogen gas to the TOGS for pressure regulation.
Provide nitrogen gas to the PCLS and the FFPS for pneumatic control mechanisms.
The FNHS is not relied upon to prevent accidents that could cause undue risk to the health and safety of the workers and the public or to control or mitigate the consequences of such accidents.
9b.7.8.2
System Description
Bulk liquid nitrogen is stored in tanks outside the main production facility and is supplied to vaporizer units. The vaporizer units vaporize the liquid nitrogen to provide a clean gaseous
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-15 Rev. 3 nitrogen supply that is piped into the main production facility. A liquid nitrogen supply line upstream of the vaporizers supplies liquid nitrogen from the bulk storage tank into the main production facility via vacuum jacketed cryogenic piping.
The FNHS supplies liquid nitrogen to an adjustable pressure phase separator inside the main production facility that has the capability to store and deliver high quality liquid nitrogen to the TPS. Liquid nitrogen is supplied to a fill station inside the main production facility. The fill station is installed to fill portable dewars for the disbursement of liquid nitrogen in small quantities as needed by facility processes. Liquid nitrogen dewars supplying the IXP are equipped with an excess flow check valve for the protection of supercell and downstream equipment. Off-gassing from the FNHS phase separator and fill station are ventilated through a connection to the radiological ventilation zone 2 exhaust subsystem (RVZ2e) inside the IF.
Inside the RCA a portion of the nitrogen supply gas is piped to a main receiver storage tank which feeds the FNHS ring header. The remainder of the nitrogen supply gas is piped to the TPS room serving the TPS.
A FNHS remote receiver tank is maintained on the FNHS ring header to supply abrupt demands and provide consistent nitrogen gas flow and pressure to all serviced areas in the RCA. The FNHS ring header supplies nitrogen gas to sampling equipment, tank sparging and mixing equipment, and level indication equipment. The FNHS ring header supplies nitrogen gas to each FNHS cooling room receiver tank where it is used by TOGS.
Table9b.7-5 identifies the systems which interface with the FNHS. Figure9b.7-6 provides a process flow diagram for the FNHS.
9b.7.8.3 Operational Analysis and Safety Function The FNHS bulk liquid nitrogen storage tanks are continuously pressurized by the naturally occurring liquid to gas phase change inside the tank with the presence of liquid nitrogen. The FNHS bulk liquid nitrogen storage tank head space pressure is regulated to provide flow to the vaporizer. A pressure relief system with a vent path to the atmosphere is maintained on each bulk liquid storage tank to prevent overpressurization of the vessel.
Liquid nitrogen is directed from the pressurized bulk storage tank to vaporizers where it is heated and vaporized to nitrogen gas. The gaseous nitrogen supply is regulated through a control manifold designed to control the pressure and prevent possible liquid carryover to the FNHS end users. The FNHS bulk liquid nitrogen storage tank and vaporizers supply nitrogen gas to the main FNHS receiver tank, the facility nitrogen gas ring header, and the FNHS remote receiver tank located inside the RCA. The control manifold ensures that adequate pressure is maintained within the main production facility. Overpressure protection is provided on the FNHS gaseous facility supply line.
The FNHS cooling room receiver tanks are filled from the facility nitrogen gas ring header by opening a normally closed manual valve allowing flow to the tank corresponding to the actuated valve. Once pressure has equalized the valve is closed and the tank is placed in service.
Redundant isolation upstream of the cooling room remote receiver tanks ensures that a direct path from the atmosphere inside confinement boundaries to outside those areas are not created.
The manual isolation provided is maintained normally closed and administrative controls ensure
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-16 Rev. 3 that the valve is only opened to service the TOGS when the associated IU and TOGS are not in service. The isolation prevents backflow from the TOGS into normally occupied IF spaces.
Shielding and radiological protection is not required for the FNHS. The FNHS contains no SNM.
The FNHS is nonsafety-related.
9b.7.8.4 Instrumentation and Control The FNHS is comprised of a packaged skid control system that includes system instrumentation.
The packaged control system interfaces with the PICS to deliver FNHS data to plant operators.
The FNHS is designed with low temperature shutdown equipment to protect downstream components from cryogenic temperatures.

9b.7.9.2
System Description
The FSDS removes domestic sanitary waste and wastewater from the areas of the main production facility (not inside the RCA), the storage building, and the resource building; and discharges sanitary waste and wastewater to the City of Janesville public sewer main.
The FSDS building sewer removes sanitary waste via a gravity drainage system. The subsystem includes distribution piping, pipe fittings, isolation valves, backwater valves, vents, traps, cleanouts, manholes, and fixtures.
9b.7.9.3 Operational Analysis and Safety Function The piping in the FSDS building sewer is sloped per the Wisconsin Administrative Code to ensure directed flow to the City of Janesville public sewer main. Building drains that are subject to backflow are protected with a backwater valve or sump and pumping equipment to comply with applicable requirements of the Wisconsin Administrative Code.
Shielding and radiological protection is not required for the FSDS. Sanitary waste sources contain no SNM.
The FSDS is nonsafety-related.

Provide for preparation of chemical reagents from bulk chemicals.
Transfer reagents from their intermediate storage locations to process at tie-in locations.
Deliver reagents into the SHINE process.
Provide compressed oxygen to the TOGS.
9b.7.10.2
System Description
Bulk chemical storage is provided in the storage building. Chemical storage is also provided in the chemical storage and preparation room in the main production facility, which is located outside the RCA. Storage of compressed oxygen gas, used as a reagent, is provided by the FCRS. Compressed oxygen is supplied to the TOGS to facilitate the recombination of radiolytic hydrogen. Other chemical reagents are used for batch production, solution adjustment, and process flushing.
Chemical reagents are placed into volume-limited FCRS containers for transfer to process tie-in location tanks and into single-use laboratory scale containers (e.g., flasks, syringes, pipets) for import into hot cells inside the RCA.
Reagents transported in portable containers are transferred into the tanks and pumped on demand directly into the respective process tie-in locations for:
TSPS uranyl sulfate solution preparation and adjustment; MEPS extraction, purification, and flushing; IXP system iodine extraction, purification, and flushing; RLWS system pH adjustment; RLWI system flushing; VTS flushing and adjustment of target solution in the TSSS; PVVS condensate pH adjustment and flush; and PSB flushing.
Chapter 9 - Auxiliary Systems Other Auxiliary Systems SHINE Medical Technologies 9b.7-18 Rev. 3 Reagents in laboratory containers are manually introduced into the MEPS purification hot cells through hot cell pass-throughs. Hot cell master-slave manipulators are used to add chemicals to the laboratory scale purification processes performed in the hot cells.
Compressed oxygen cylinders are stored inside the IF to service the TOGS. Compressed oxygen is routed through dry particulate filters, regulated, and distributed to the TOGS.
Table9b.7-6 identifies the systems which interface with the FCRS.
9b.7.10.3 Operational Analysis and Safety Function Bulk liquid and solid chemicals and chemical reagents are received, stored, maintained, and used in accordance with the chemical hygiene plan and are stored per their applicable safety data sheets.
The FDWS provides demineralized water to both the storage building and the chemical storage and preparation room for chemical reagent preparation. Individual acid, base, and organic waste containers are provided for disposal of chemicals.
Reagents from FCRS process delivery tanks are pumped directly into the respective process tie-in points at controlled flow rates and temperatures in accordance with the process requirements.
Administrative and engineered controls, including accurate identification of reagents inside process delivery tanks and containers, and color-coded and size specific connections, ensure that reagents are not inadvertently supplied at incorrect process tie-in points. The FCRS process delivery tanks are volume limited, thereby setting maximum volume of reagents that can be supplied to respective production-related processes.
Mixing of acids and bases could cause a highly exothermic reaction. As such, bulk quantities of acids are stored separately from the bases and hydrogen peroxide in segregated storage spaces within the storage building. Small volumes of chemicals to be used in laboratory settings and in processes are stored and labeled in accordance with their applicable safety data sheets.
Table13b.3-1 provides a list of chemicals within the SHINE facility.
The storage and delivery of oxygen gas inside the RCA complies with fire hazard analysis (FHA),
as described in Section9a2.3, and applicable Occupational Safety and Health Administration (OSHA) requirements.
FCRS operations are performed in accordance with the requirements of the radiation protection program, described in Section11.1.
The FCRS contains no SNM; however, the addition of basic chemical reagents to interfacing systems may result in uranium precipitation. Therefore, chemical additions to process tanks are evaluated under the nuclear criticality safety program, as described in Section6b.3.
9b.7.10.4 Instrumentation and Control Process parameters for systems interfacing with the FCRS are monitored by the PICS, as described in Section7.3.
