OL-2011/1311.2LIQUIDWASTEMANAGEMENTSYSTEMS Several systems within the plant serve to control, collect, process, handle, store, recycle, and dispose of liquid radioactive waste generated as a result of normal plant operation, including anticipated operational occurrences. This section discusses the design and operating features and performance of the liquid radwaste system and the performance of other liquid waste management systems which are discussed in other sections. 11.2.1DESIGN BASES 11.2.1.1SafetyDesignBasis Except for two containment penetrations and the component cooling water side of the reactor coolant drain tank heat exchanger, the liquid radwaste system (LRWS) is not a safety-related system. SAFETY DESIGN BASIS ONE - The containment isolation valves in the LRWS are selected, tested, and located in accordance with the requirements of 10 CFR 50, Appendix A, GDC-56, and 10 CFR 50, Appendix J, Type C testing. 11.2.1.2PowerGenerationDesignBasesPOWER GENERATION BASIS ONE - The LRWS, in conjunction with other liquid waste management systems, is designed to meet the requirements of the discharge concentration limits of 10 CFR20 and the ALARA dose objective of 10 CFR 50, Appendix I. POWER GENERATION DESIGN BASIS TWO - The LRWS uses design and fabrication codes consistent with quality group D (augmented), as assigned by Regulatory Guide 1.143, for radioactive waste management systems. POWER GENERATION DESIGN BASIS THREE - Liquid effluent discharge paths are monitored for radioactivity. 11.2.2SYSTEM DESCRIPTION 11.2.2.1GeneralDescription This section describes the design and operating features of the LRWS. The performanceof the LRWS, in conjunction with other liquid waste management systems, is discussed in Section 11.2.3. Detailed descriptions of other liquid waste management systems are provided in the following sections: a.Boron recycle9.3.6b.Steam generator blowdown10.4.8 CALLAWAY - SP11.2-2Rev. OL-2011/13The piping and instrumentation diagram for the LRWS is shown in Figure 11.2-1 | ||
. The LRWS collects, processes, and discharges water entering the system. Equipment drains and waste streams are normally segregated to prevent the intermixing of the liquid wastes. The LRWS is capable of processing plant effluent for recycling reactor grade water, however, normally no tritiated water is transferred to the Reactor Makeup Water Storage Tank (RMWST). This method of operation prevents the contamination of Secondary systems due to deoxygenating the Reactor Makeup Water System (BL) water using the Demineralized Water Makeup Storage and Transfer System (AN).The LRWS consists of five waste collection subsystems and three waste processing subsystems:a.tritiated waste (CRW) drain subsystemb.potentially radioactive nontritiated waste (DRW) drain subsystemc.the Reactor Coolant Drain Tank subsystem (RCDT)d.the Chemical Waste subsysteme.the Laundry Waste subsystem f.the Liquid Radwaste Treatment subsystem (LRWTS)g.the Alternate Liquid Radwaste Treatment subsystemh.the Discharge Monitor Tank subsystemTritiated wastes (CRW), potentially radioactive nontritiated waste (DRW) and laundry waste drainage are discussed in Section 9.3.3 | |||
.The various waste streams are processed as follows:CRW SUBSYSTEM INFLUENTS - The CRW system processes all water that can be recycled. The CRW influents consist of reactor coolant which has been exposed to the atmosphere and has become aerated. This waste consists of equipment drains, leakoffs, and overflows from tritiated systems (e.g., CVCS and reactor coolant samples which have not been chemically contaminated). c.CVCS boron thermal regeneration and purification9.3.4d.Secondary liquid waste10.4.10 CALLAWAY - SP11.2-3Rev. OL-2011/13This waste is typically collected in the floor and equipment drain system and then transferred to the waste holdup tank. CRW influents are normally processed using the LRWTS and discharged from the plant.DRW SUBSYSTEM INFLUENTS - DRW influents are miscellaneous liquid wastes collected by the floor drain system within the radiologically controlled areas of the plant. The controlled access areas are radiation zones B through E and include the containment, auxiliary building, fuel building, radwaste building, and the access control areas of the control building.Floor drainage consists of miscellaneous leakage from systems within the above areas. Generally, the amount of highly radioactive reactor coolant leakage into the drain system is very small. The bulk of the water originates as leakage from nonradioactive or slightly radioactive systems, such as the service water and component cooling water systems. In addition to system leakage, the floor drain systems will collect decontamination water used for area washdowns, spent fuel cask decontamination, and laboratory equipment decontamination and rinses. Highly chemically contaminated decontamination solutions are normally not allowed to enter the floor drain system. During maintenance, equipment drains from nontritiated systems will normally be directed to the floor drain system. Large volumes of component cooling water will not normally be drained to the floor drain system to prevent contamination of the LRWS by corrosion inhibitors. DRW influents are collected in two floor drain tanks and are normally processed using the LRWTS and discharged from the plant.REACTOR COOLANT DRAIN TANK WASTE (RCDT) - Sources of water entering the reactor coolant drain tank include the reactor vessel flange leakoff, valve leakoffs, reactor coolant pump number two seal leakoffs, and the excess letdown heat exchanger flow. No continuous leakage is expected from the reactor vessel flange during operation. The tank is provided with a hydrogen cover gas to minimize dissolved air or nitrogen buildup in the GRWS. This water may be transferred to the Recycle Holdup Tanks and processed with the Boron Recycle System or transferred to the Waste Holdup tank for processing and discharge.HIGH LEVEL CHEMICAL WASTE - High level chemical waste consists of plant samples which have been chemically contaminated. These wastes are collected in the chemical drain tank where pH adjustment is possible. These wastes are normally drained to the floor drain system for processing.LAUNDRY AND PERSONNEL DECONTAMINATION WASTE - Laundry waste is generated by the washing of radioactively contaminated protective clothing and gear for reuse. The personnel decontamination waste contains detergents (inorganics) and/or soaps (organics) used by personnel to remove low level radioactive contamination. The hot showers (Men's shower and Decon shower) in the access control area are used occasionally for personal use and for personnel decontamination when needed. | |||
CALLAWAY - SP11.2-4Rev. OL-2011/13Personnel decontamination wastes are collected in the detergent waste subsystem's detergent drain tank and then transferred to the laundry and hot shower tanks. Laundry waste is collected in the sump located in the Laundry Decontamination Facility and then transferred over to the laundry and hot shower tanks. The waste is then processed and discharged.The various radwaste processing systems are described as follows:LIQUID RADWASTE TREATMENT SYSTEM (LRWTS) - The liquid radwaste treatment system consists of a vendor supplied skid containing a chemical injection system along with a series of demineralizer vessels. The vessels may be operated in any combination or with any treatment media required to process the waste water effectively. Waste water from the CRW and DRW is processed through the components of the LRWTS on an as needed basis to remove the contaminants of concern. Influents to the boron recycle system and RCDT system may be processed with the LRWTS if the recycling of reactor coolant is not desired. Also waste water collected in the laundry and hot shower tanks may be processed through this equipment. The secondary liquid waste monitor tanks normally provide a holdup capacity and the ability to recirculate and sample process stream effluent prior to transferring the processed water to the Discharge Monitor Tanks for discharge.ALTERNATE LIQUID RADWASTE TREATMENT SYSTEM - During situations when the LRWTS is not available, the floor drain tanks and waste holdup tank may be processed by a backup means. The alternate liquid radwaste treatment system consists of a series of filters, demineralizers, charcoal adsorbers and monitor tanks. Waste water from the CRW and DRW system can be processed through these components on an as need basis to remove contaminates of concern. Intermediate monitoring tanks provide a holdup capacity and the ability to recirculate and sample process steam effluent prior to transferring the processed water to the Discharge Monitor Tanks.DISCHARGE MONITOR TANKS - The Discharge Monitor Tanks receive effluents from the LRWTS, Alternate Liquid Radwaste Treatment system, Laundry Waste system and the Secondary Liquid Waste system. The DMT's provide for a final holdup and processing to ensure the effluent quality of the waste water is acceptable for discharge to the environment.Modifications to the Radwaste Systems such as the addition of the LRWS have resulted in the obsolescence of various radwaste equipment and components that are currently installed and pending formal retirement. Operating procedures that govern this equipment have been updated to ensure operation of the obsolete equipment does not occur. Obsolete radwaste equipment/components, along with the equipment identification numbers, system status, and associated FSAR figures, are listed below.a.Recycle evaporator package (SHE02) - pending retirement - FSAR Figure 9.3-11 Sheet 3 CALLAWAY - SP11.2-5Rev.

The pumps are cross-connected to the pump from either floor drain tank.WASTE MONITOR TANK PUMPS - One standard pump is to be used for each tank to transfer water. The pump may also be used for circulating the water in the waste monitor tank in order to obtain uniform tank contents and hence a representative sample before discharge. The pump can be throttled to achieve the desired discharge rate. ACID METERING PUMP - One positive displacement chemical feed pump used to inject sulfuric acid into the discharge monitor tank discharge for pH control.CAUSTIC METERING PUMP - One positive displacement chemical feed pump used to inject sodium hypochlorite into the discharge monitor tank discharge for pH control.REACTOR COOLANT DRAIN TANK HEAT EXCHANGER - The reactor coolant drain tank heat exchanger is a U-tube type with one shell pass and two tube passes. Although the heat exchanger is normally used in conjunction with the reactor coolant drain tank, it can also cool the pressurizer relief tank from 200 to 120°F in less than 8hours. REACTOR COOLANT DRAIN TANK - One tank is provided to collect leakoff type drains inside the containment at a central collection point for further disposition through a single penetration via the reactor coolant drain tank pumps. Only water which can be directed to the recycle holdup tanks enters the reactor coolant drain tank. The tank is provided with a hydrogen cover gas. The water must be compatible with reactor coolant, and it must not contain dissolved air or nitrogen to minimize buildup in the GRWS. Sources of water entering the reactor coolant drain tank include the reactor vessel flange leakoff, valve leakoffs, reactor coolant pump number two seal leakoffs, and the excess letdown heat exchanger flow. No continuous leakage is expected from the reactor vessel flange during operation. WASTE HOLDUP TANK - One atmospheric pressure tank is provided outside the containment to collect equipment drainage, valve and pump seal leakoffs, recycle holdup tank overflows, and other water from tritiated, aerated sources. WASTE EVAPORATOR CONDENSATE TANK - One tank is provided to collect processed waste water from the LRWTS or the Alternate LRWTS. | ||

CALLAWAY - SP11.2-8Rev. OL-2011/13Operation of the LRWS is essentially the same during all phases of normal reactor plant operation; the only differences are in the load on the system. The following sections discuss the operation of the system in performing its various functions. In this discussion, the term "normal operation" should be taken to mean all phases of operation, except operation under emergency or accident conditions. The LRWS is not regarded as a safety-related system. CRW SUBSYSTEM OPERATION - Waste is accumulated in the waste holdup tank until a sufficient quantity exists to process. Normally the waste holdup tank is recirculated and sampled prior to being processed. Chemistry of the tank may be adjusted to ensure optimum system performance. Normally the waste holdup tank is processed utilizing the LRWTS. If the LRWTS is not available, the capability exists to process the waste holdup tank with the alternate liquid radwaste treatment system. If necessary, caustic or acid solution may be added to the waste water by caustic or acid metering pumps to bring the pH into allowable discharge specifications.DRW SUBSYSTEM OPERATION - Normally one floor drain tank is aligned to receive the discharge from the floor drain system while the other tank is being used to supply waste to the processing system. This procedure allows the waste to be sampled and pH adjusted, if desired, prior to processing, to ensure optimum system performance. The second floor drain tank also provides additional system storage capacity during periods of abnormal waste generation or equipment outages. The floor drain tanks are normally processed through the floor drain tank filter to the LRWTS. If the LRWTS is not available, the capability exists to process the floor drain tanks with the alternate liquid radwaste treatment system.REACTOR COOLANT DRAIN TANK SUBSYSTEM OPERATION - Normal operation of the reactor coolant drain subsystem is in the manual mode. Due to the small amount of leakage into the system, less wear and tear on the equipment is experienced by maintaining it in the manual mode. The tank level is monitored by the radwaste operators and pumped out when necessary. The leakage rate of reactor coolant pump No. 2 seal leakoffs, reactor vessel flange leakoffs, valve stem leakoffs and discharges from the excess letdown heat exchanger into the reactor coolant drain tank (RCDT) can be estimated by leaving the system in manual mode and watching the rate of level change. This will measure the identified leakage. The reactor coolant drain tank pumps normally discharge to the boron recycle system. These drains can also be aligned to the waste holdup tank. When in the automatic mode, the level in the RCDT is maintained by running one RCDT pump continuously and using a proportional control valve (LCV-1003) in the discharge line. This valve operates on a signal from the RCDT level controller to limit the flow out of the subsystem. The remainder of the flow is recirculated to the RCDT. The RCDT heat exchanger is sized to maintain the RCDT contents at or below 170°F, assuming an in-leakage of 10 gpm at 600°F.A venting system is provided to prevent wide pressure variations in the RCDT. Normally, the pressure in the RCDT is manually controlled by raising/lowering level in the tank. If too much pressure has built up in the RCDT and cannot be controlled by lowering the CALLAWAY - SP11.2-9Rev. OL-2011/13tank level, manual valves can be opened to the gaseous radwaste system to lower the pressure in the RCDT. The manual valves may also be operated to raise the tank's gaseous overpressure as needed. Hydrogen cover gas is supplied from the service gas system and can be automatically maintained between 2 and 6 psig by pressure-regulating valves. PCV-7155 maintains a minimum tank pressure by admitting hydrogen, while PCV-7152 maintains maximum tank pressure by venting the RCDT to the gaseous radwaste system. The hydrogen is supplied from no more than two 194 SCF bottles, to limit the amount of hydrogen gas which might be accidentally released to the containment atmosphere. The RCDT vents to the gaseous radwaste system to limit any releases of radioactive gases. The reactor coolant drain subsystem may also be used in the pressurizer relief tank (PRT) cooling mode of operation. In this mode, the level control valve in the discharge line to the recycle evaporator feed demineralizers (LCV-1003), the isolation valve at the discharge of the reactor coolant drain tank (HV-7127), and the isolation valve in the reactor coolant drain tank recirculation line (HV-7144) are all closed. The PRT contents are circulated through the reactor coolant drain tank heat exchanger, via valve BB-HV-8031 and the reactor coolant drain tank pumps, prior to returning to the PRT via valve BB-HV-7141. In this mode of operation, the RCDT heat exchanger is capable of cooling the PRT contents from 200°F to 120°F in less than 8 hours. As an alternative to returning the cooled fluid to the PRT, the fluid may be directly transferred to the recycle holdup tanks in the boron recycle system. In any and all cases of PRT cooling, the PRT is vented to less than 50 psig to prevent overpressurization of the RCDT subsystem.The reactor coolant drain subsystem may be used to drain the reactor coolant loops by first venting the reactor coolant system, then connecting the spool piece in the RCDT pump suction piping. The design objective of this mode of operation is to drain the RCS to the midpoint of the reactor vessel nozzles in less than 8 hours with both RCDT pumps running. In this mode, valve HV-7144 is closed and, in order to maximize flow capability, the RCDT discharge level control valve (LCV-1003) should be bypassed during RCS draining operations.The reactor coolant drain subsystem may be used to drain down portions of the refueling pool which cannot be drained by the residual heat removal pumps. In this mode of operation, the RCDT heat exchanger may be bypassed and the RCDT level control valve (LCV-1003) may be bypassed to maximize flow through the fuel pool cooling and cleanup system to the refueling water storage tank. An alternate drain line is provided from the refueling pool to the containment sump to route decontamination chemicals away from the RCDT subsystem and minimize the possibility of contaminating any systems downstream of the RCDT pumps.CHEMICAL WASTE - The chemical drain tank (CDT) receives chemically contaminated tritiated water from the plant sample stations. Contents of the tank are sampled, and normally drained to the floor drain system. Operation is intermittent and manually controlled. A high level alarm is provided from the CDT for operator information. | CALLAWAY - SP11.2-8Rev.

CALLAWAY - SP11.2-10Rev. OL-2011/13LAUNDRY SUBSYSTEM OPERATION - Waste water from the Deep sinks, a washing machine, Men's shower and the personnel decontamination shower are directed by gravity drain to the detergent drain tank located in the basement of the control building and then is pumped to the laundry and hot shower tanks (L&HST's). Laundry waste from the washers and the dryers located in the Laundry Decontamination Facility are collected in the building sump and also pumped over to the L&HST's. The L&HST fluid is low in radioactivity and is normally processed by the L&HST bag filters. The waste may be directed to waste monitor tank "B" and subsequently to the discharge monitor tanks for discharge or directly to the discharge monitor tanks.The laundry system requires makeup water that is normally from a radiologically "clean" source (i.e., Potable water) because water is taken from the system in wet clothes, evaporated in the dryers, and vented from the plant. Potable water will be connected to an OZONE generator, which will provide the bulk of the cleaning agent for the washing machines. Ozone cleans by breaking down the organic molecules in the water and is more effective than chlorine in killing bacteria and reduces or eliminates the need for detergents. Since Ozone requires little or no detergent, there are less residual chemicals in the fabrics after the rinse cycle and fewer rinse cycles are needed. The laundry water is then pumped, on demand of the washing machines, to the laundry equipment in operation. Although the ozone works best in cold water, one washing machine will be equipped with a steam heating system if hot water might be needed. In all phases of laundry operation, the operator must take care to use detergents, soaps, and additives that are compatible with waste processing equipment.DISCHARGE MONITOR TANKS - Normally one discharge monitor tank is aligned to receive plant waste while the other tank is being prepared for discharge. Waste is accumulated until a sufficient quantity exists for processing. The tank is isolated, recirculated, sampled and permitted prior to discharge. The capability exists to reprocess or adjust tank chemistry as necessary to ensure environmental effluent requirements are met. The second discharge monitor tank also provides additional system storage capacity during periods of abnormal waste generation.The LRW system is designed to handle the occurrence of equipment faults of moderate frequency such as:a.Malfunction in the LWRSMalfunction in this system could include such things as pump or valve failures. Because of pump standardization throughout the system, a spare pump can be used to replace most pumps in the system. There is sufficient surge capacity in the system to accommodate waste until the failures can be fixed and normal plant operation resumed.b.Excessive leakage in reactor coolant system equipment CALLAWAY - SP11.2-11Rev. OL-2011/13The system is designed to handle a 1-gpm reactor coolant leak in addition to the expected leakage of 50 lb/day (Ref. 1) during normal operation, which is discussed in Section 5.2.5. Operation of the system is almost the same for normal operation, except that the load on the system is increased. A 1-gpm leak into the reactor coolant drain tank is handled automatically but will increase the load factor of the recycle system. If the gpm leak enters the waste holdup tank, operation is the same as normal, except for the increased load on the system. Abnormal liquid volumes of reactor coolant resulting from excessive reactor coolant or auxiliary building equipment leakage (in excess of 1 gpm) can also be accommodated by the floor drain tank and processed by the LRWTS. Valve and pump leakoffs containing recyclable water are recycled through the waste holdup tank.c.Excessive leakage in the auxiliary system equipmentLeakage of this type could include water from steam side leaks and fan cooler leaks inside the containment which are collected in the containment sump and sent to the floor drain tank. Other sources could be component cooling water leaks, service water leaks, and secondary side leaks. This water will enter the floor drain tank and will be processed and discharged as during normal operation.11.2.3RADIOACTIVE RELEASES This section describes the estimated liquid release from the plant for normal operation and anticipated operational occurrences. 11.2.3.1SourcesSection 11.1 and Appendix 11.1A provide the bases for determining the contained sources inventory and the normal releases.

OL-2211/1611.3GASEOUSWASTEMANAGEMENTSYSTEMSThe gaseous radwaste system (GRWS) and the plant ventilation exhaust systems control, collect, process, store, and dispose of gaseous radioactive wastes generated as a result of normal operation, including anticipated operational occurrences. This section discusses the design, operating features, and performance of the GRWS and the performance of the ventilation systems. The plant ventilation exhaust systems accommodate other potential release paths for gaseous radioactivity due to miscellaneous leakages, aerated vents from systems containing radioactive fluids, and the removal of noncondensables from the secondary system. Systems which handle these gases are not normally considered gaseous waste systems and are discussed in detail in other sections. These systems are included here to the extent that they represent potential release paths for gaseous radioactivity. 11.3.1DESIGN BASES 11.3.1.1SafetyDesignBasisThe GRWS and other gaseous waste management systems serve no safety-related function. 11.3.1.2PowerGenerationDesignBasesPOWER GENERATION DESIGN BASIS ONE-The GRWS and the ventilation exhaust systems are designed to meet the requirements of the discharge concentration limits of 10CFR20 and the as low as reasonably achievable dose objective of 10CFR50, AppendixI.

CALLAWAY - SP11.3-2Rev. OL-2211/1611.3.2SYSTEM DESCRIPTIONS11.3.2.1GeneralDescriptionThis section describes the design and operating features of the GRWS. The performance of the GRWS and other plant gaseous waste management systems with respect to the release of radioactive gases is discussed in Section11.3.3. Detailed descriptions of the plant ventilation systems and main condenser evacuation system are presented in Sections9.4 and 10.4.2, respectively. The piping and instrumentation diagram for the GRWS is shown in Figure11.3-1. The main flow path in the GRWS is a closed loop comprised of two waste gas compressors, two catalytic hydrogen recombiners, six gas decay tanks for normal power service, and two gas decay tanks for service at shutdown and startup. The system also includes a gas decay tank drain collection tank, drain pump, four gas traps to handle normal operating drains from the system, and a waste gas drain filter to permit maintenance and handle normal operating drains from the system. All of the equipment is located in the radwaste building. The closed loop has nitrogen for a carrier gas. The primary influents to the GRWS are combined with hydrogen as the stripping or carrier gas. The hydrogen that is introduced to the system is recombined with oxygen, and the resulting water is removed from the system. As a result, the bulk of all influent gases is removed, leaving trace amounts of inert gases, such as helium and radioactive noble gases to build up. The primary source of the radioactive gas is via the purging of the volume control tank with hydrogen, as described in Section9.3.4. The operation of the GRWS serves to reduce the fission gas concentration in the reactor coolant system which, in turn, reduces the escape of fission gases from the reactor coolant system during maintenance operations or through equipment leakage. Smaller quantities are received, via the vent connections, the reactor coolant drain tank, the pressurizer relief tank, and the recycle holdup tanks. Since hydrogen is removed in the recombiner, this gas does not build up within the system. The largest contributor to the nonradioactive gas accumulation is helium generated by a B10(n,a)Li7 reaction in the reactor core. The second largest contributors are impurities in the bulk hydrogen and oxygen supplies. Stable and long-lived isotopes of fission gases also contribute small quantities to the system gas volume accumulation.Operation of the system is such that fission gases are distributed throughout the six normal operation gas decay tanks. Separation of the GRWS gaseous inventory in several tanks assures that the allowable site boundary dose will not be exceeded in the event of a gas decay tank rupture. Radiological consequences of such a postulated rupture are discussed in Section15.7.1. | °F200Design flow, gpm Point 135 Point 2100 Design head, ft Point 1250 Point 2230 CALLAWAY - SPTABLE 11.2-1 (Sheet 4)Rev.

CALLAWAY - SP11.3-3Rev. OL-2211/16The GRWS also provides the capacity for indefinite holdup of gases generated during reactor shutdown. Nitrogen gas from previous shutdowns is contained in one of the shutdown gas decay tanks for use in stripping hydrogen from the reactor coolant system. The second shutdown tank is normally at low pressure and is used to accept relief valve discharges from the normal operation gas decay tanks. For all buildings where there is potential airborne radioactivity, the ventilation systems are designed to control the release. Where applicable, each building has a vent collection system for tanks and other equipment which contains air or aerated liquids. The condenser evacuation system discharge is filtered and discharged to the unit vent in addition to the discharges from the reactor building, auxiliary building, and fuel building. The radwaste building, which houses the GRWS, has its own release vent. The turbine building has an open ventilation system, and the steam packing exhaust discharges into the turbine building. The vent collection systems receive the discharge of vents from tanks and other equipment in the radwaste and auxiliary buildings which contain air or aerated liquids. These components contain only a very small amount of fission product gases. Prior to release via the radwaste or auxiliary building ventilation system, the gases are monitored, as described in Section11.5, and passed through a prefilter, HEPA filter, charcoal filter, and another HEPA filter in series which reduce any airborne particulate radioactivity to negligible levels and provide a decontamination factor of at least 10 for radioactive iodines and 100 for particulates. Expected efficiencies for iodine removal are better than 99percent for elemental iodine and 95percent for organic iodine at 70-percent relative humidity. However, for gaseous effluent release calculations, 70-percent efficiency is conservatively used for radioiodine isotopes. Although plant operating procedures, equipment inspection, and preventive maintenance are performed during plant operations to minimize equipment malfunction, overall radioactive release limits have been established as a basis for controlling plant discharges during operation with the occurrence of a combination of equipment faults of moderate frequency. These faults include operation with fuel defects in combination with steam generator tube leaks and malfunction of liquid or gaseous waste processing systems or excessive leakage in reactor coolant system equipment or auxiliary system equipment. Operational occurrences such as these can result in the discharge of radioactive gases from various plant systems. These unscheduled discharges may be from plant systems which are not normally considered gas processing systems or from a gas decay tank after a 60-day holdup period. If the holdup period restricts plant operation, it may be necessary to decrease this time with prior approval from the Manager, Radiation Protection. These potential sources are tabulated in Table11.1-2. The bases for assumed releases, the factors which tend to mitigate the release of radioactivity, and the release paths are given in Appendix11.1A. A further discussion of the gaseous releases from the plant is provided in Section11.3.3. | °F200Design flow, gpm Point 135 Point 2100 Design head, ft Point 1250 Point 2230 MaterialStainless steel Design codeMS Laundryand Hot Shower Tank A PumpNumber1 TypeInline centrifugal Design pressure, psig150 Design temperature, | ||
CALLAWAY - SP11.3-4Rev. OL-2211/1611.3.2.2ComponentDescriptionCodes and standards applicable to the GRWS are listed in Tables3.2-1 and 11.3-1. The GRWS is designed and constructed in accordance with quality groupD (augmented). The GRWS is seismically designed, as discussed in Table3.2-5. The GRWS is housed within a seismically designed building. The GRWS design complies with Regulatory Guide1.143, as specified in Table3.2-5. WASTE GAS COMPRESSOR-The waste gas compressor is a water-sealed centrifugal displacement unit which maintains continuous circulation of nitrogen around the waste gas loop. The compressor is provided with a mechanical shaft seal to minimize water leakage. The compressor moisture separator normal water level is maintained to keep the shaft immersed at all times. Two waste gas compressor packages are provided. One compressor is normally used, and the other compressor is on standby. The packages are self-contained and skid-mounted. Construction is primarily of carbon steel. CATALYTIC HYDROGEN RECOMBINER-The catalytic recombiner disposes of hydrogen brought into the GRWS. This is accomplished by adding a controlled amount of oxygen to the recombiner which reacts with the hydrogen as the gas flows through a catalyst bed. The control system for the recombiner is designed to preclude the possibility of a hydrogen explosion. This is further discussed in Section11.3.6. Two hydrogen recombiner packages are provided. One recombiner is normally used, and the other is on standby. The packages are self-contained and skid-mounted. The recombiner is located in the system where the hydrogen concentration and pressure are optimum with respect to hydrogen removal. DECAY TANK-Eight gas decay tanks are provided, six for normal power operation and two for service at shutdown and startup. The tanks are of the vertical-cylindrical type and are constructed of carbon steel. MISCELLANEOUS COMPONENTS-The gas decay drain collection tank provides a collection point for condensation drained from the gas decay tanks, recombiners, and gas compressors. All control valves, with the exception of those on the recombiner, are provided with bellow seals to minimize the leakage of radioactive gases through the valve bonnet and stem. Valves on the recombiner package are provided with leakoffs. Relief valves have soft seats and are exposed to pressures which are normally less than two-thirds of the relief valve set pressure. The relief valves of the major components discharge to the shutdown tanks. This permits decay and controlled disposal of all discharges less than about 3,000scf. The relief valves are designed to relieve full flow from both waste gas compressors. | °F200Design flow, gpm35 Design head, ft81 MaterialStainless steel Design codeMS CALLAWAY - SPTABLE 11.2-1 (Sheet 5)Rev.

CALLAWAY - SP11.3-5Rev. OL-2211/16To maintain leakage from the system at the lowest practicable level, diaphragm-type manual valves are used throughout the waste gas system. For low temperature, low pressure service valves with a synthetic rubber-type diaphragm are used. This application includes all parts of the system, except the recombiners. Because of the high temperature that may exist in the recombiner, globe type valves with a metal diaphragm seal in the stem are used. There should be no measurable stem leakage from either type of valve. The gas decay tank drain pump directs water from the gas decay drain collection tank (due to condensation or maintenance) to the waste holdup tank or recycle holdup tanks. It is used when there is insufficient pressure in the gas system to drive the fluid. All parts of the pump in contact with the drain water are of austenitic stainless steel. The pump is a canned-motor type. The waste gas drain filter is a disposable cartridge filter provided to prevent particulate matter, including rust, larger than 30microns from entering the LRWS and BRS. All parts of the filter in contact with the drain water are of austenitic stainless steel. The waste gas traps are designed to prevent gases from leaving the GRWS. There are four gas traps-two in the gas decay tank drain line and one each in the recombiner drain lines and compressor drain lines. The component description for the ventilation systems is provided in Section9.4. 11.3.2.3SystemOperationOperation of the ventilation systems is described in Section9.4. The following is a description of the GRWS. NORMAL OPERATION - The GRWS system is normally operated when increased fission gases or excess hydrogen levels have accumulated in the volume control tank (VCT). When needed, nitrogen gas, with contained fission gases, is circulated around the GRWS loop by one of the two compressors. Fresh hydrogen gas is introduced into the VCT where it is mixed with fission gases stripped from the reactor coolant by the action of the VCT letdown line spray nozzle. The gas is vented from the VCT into the circulating nitrogen in the waste gas system, at the compressor suction.The resulting mixture of nitrogen, hydrogen, and fission gases is pumped by one of the compressors to one of the two catalytic hydrogen recombiners where enough oxygen is added to react with and reduce the hydrogen to a low residual level. Water vapor formed in the recombiner by the hydrogen and oxygen reaction is condensed and removed, and the cooled gas stream (now composed primarily of nitrogen, helium, and fission gases) is discharged from the recombiner, routed through a gas decay tank, and sent back to the compressor suction to complete the loop circuit. Only one gas decay tank is valved into the waste gas loop at any time. | °F200Design flow, gpm250 Design head, ft200 MaterialStainless steel Design codeMS Caustic Metering PumpNumber1 TypePulsafeeder Design Pressure100 PSIG Design Flow, GPH63 MaterialsDiaphragmReagent headTeflon (virgin)Stainless SteelDesign CodeMS Acid Metering PumpNumber1 TypePulsafeeder Design Pressure100 PSIG Design Flow, GPH63 MaterialsDiaphragmReagent headTeflon (virgin)Stainless SteelDesign CodeMS CALLAWAY - SPTABLE 11.2-1 (Sheet 6)Rev.

OL-2211/1611.3GASEOUSWASTEMANAGEMENTSYSTEMSThe gaseous radwaste system (GRWS) and the plant ventilation exhaust systems control, collect, process, store, and dispose of gaseous radioactive wastes generated as a result of normal operation, including anticipated operational occurrences. This section discusses the design, operating features, and performance of the GRWS and the performance of the ventilation systems. The plant ventilation exhaust systems accommodate other potential release paths for gaseous radioactivity due to miscellaneous leakages, aerated vents from systems containing radioactive fluids, and the removal of noncondensables from the secondary system. Systems which handle these gases are not normally considered gaseous waste systems and are discussed in detail in other sections. These systems are included here to the extent that they represent potential release paths for gaseous radioactivity. 11.3.1DESIGN BASES 11.3.1.1SafetyDesignBasisThe GRWS and other gaseous waste management systems serve no safety-related function. 11.3.1.2PowerGenerationDesignBasesPOWER GENERATION DESIGN BASIS ONE-The GRWS and the ventilation exhaust systems are designed to meet the requirements of the discharge concentration limits of 10CFR20 and the as low as reasonably achievable dose objective of 10CFR50, AppendixI.

CALLAWAY - SP11.3-2Rev. OL-2211/1611.3.2SYSTEM DESCRIPTIONS11.3.2.1GeneralDescriptionThis section describes the design and operating features of the GRWS. The performance of the GRWS and other plant gaseous waste management systems with respect to the release of radioactive gases is discussed in Section11.3.3. Detailed descriptions of the plant ventilation systems and main condenser evacuation system are presented in Sections9.4 and 10.4.2, respectively. The piping and instrumentation diagram for the GRWS is shown in Figure11.3-1 | |||
. The main flow path in the GRWS is a closed loop comprised of two waste gas compressors, two catalytic hydrogen recombiners, six gas decay tanks for normal power service, and two gas decay tanks for service at shutdown and startup. The system also includes a gas decay tank drain collection tank, drain pump, four gas traps to handle normal operating drains from the system, and a waste gas drain filter to permit maintenance and handle normal operating drains from the system. All of the equipment is located in the radwaste building. The closed loop has nitrogen for a carrier gas. The primary influents to the GRWS are combined with hydrogen as the stripping or carrier gas. The hydrogen that is introduced to the system is recombined with oxygen, and the resulting water is removed from the system. As a result, the bulk of all influent gases is removed, leaving trace amounts of inert gases, such as helium and radioactive noble gases to build up. The primary source of the radioactive gas is via the purging of the volume control tank with hydrogen, as described in Section9.3.4. The operation of the GRWS serves to reduce the fission gas concentration in the reactor coolant system which, in turn, reduces the escape of fission gases from the reactor coolant system during maintenance operations or through equipment leakage. Smaller quantities are received, via the vent connections, the reactor coolant drain tank, the pressurizer relief tank, and the recycle holdup tanks. Since hydrogen is removed in the recombiner, this gas does not build up within the system. The largest contributor to the nonradioactive gas accumulation is helium generated by a B10(n,a)Li7 reaction in the reactor core. The second largest contributors are impurities in the bulk hydrogen and oxygen supplies. Stable and long-lived isotopes of fission gases also contribute small quantities to the system gas volume accumulation.Operation of the system is such that fission gases are distributed throughout the six normal operation gas decay tanks. Separation of the GRWS gaseous inventory in several tanks assures that the allowable site boundary dose will not be exceeded in the event of a gas decay tank rupture. Radiological consequences of such a postulated rupture are discussed in Section15.7.1 | |||
. | |||
CALLAWAY - SP11.3-3Rev. OL-2211/16The GRWS also provides the capacity for indefinite holdup of gases generated during reactor shutdown. Nitrogen gas from previous shutdowns is contained in one of the shutdown gas decay tanks for use in stripping hydrogen from the reactor coolant system. The second shutdown tank is normally at low pressure and is used to accept relief valve discharges from the normal operation gas decay tanks. For all buildings where there is potential airborne radioactivity, the ventilation systems are designed to control the release. Where applicable, each building has a vent collection system for tanks and other equipment which contains air or aerated liquids. The condenser evacuation system discharge is filtered and discharged to the unit vent in addition to the discharges from the reactor building, auxiliary building, and fuel building. The radwaste building, which houses the GRWS, has its own release vent. The turbine building has an open ventilation system, and the steam packing exhaust discharges into the turbine building. The vent collection systems receive the discharge of vents from tanks and other equipment in the radwaste and auxiliary buildings which contain air or aerated liquids. These components contain only a very small amount of fission product gases. Prior to release via the radwaste or auxiliary building ventilation system, the gases are monitored, as described in Section11.5, and passed through a prefilter, HEPA filter, charcoal filter, and another HEPA filter in series which reduce any airborne particulate radioactivity to negligible levels and provide a decontamination factor of at least 10 for radioactive iodines and 100 for particulates. Expected efficiencies for iodine removal are better than 99percent for elemental iodine and 95percent for organic iodine at 70-percent relative humidity. However, for gaseous effluent release calculations, 70-percent efficiency is conservatively used for radioiodine isotopes. Although plant operating procedures, equipment inspection, and preventive maintenance are performed during plant operations to minimize equipment malfunction, overall radioactive release limits have been established as a basis for controlling plant discharges during operation with the occurrence of a combination of equipment faults of moderate frequency. These faults include operation with fuel defects in combination with steam generator tube leaks and malfunction of liquid or gaseous waste processing systems or excessive leakage in reactor coolant system equipment or auxiliary system equipment. Operational occurrences such as these can result in the discharge of radioactive gases from various plant systems. These unscheduled discharges may be from plant systems which are not normally considered gas processing systems or from a gas decay tank after a 60-day holdup period. If the holdup period restricts plant operation, it may be necessary to decrease this time with prior approval from the Manager, Radiation Protection. These potential sources are tabulated in Table11.1-2 | |||
. The bases for assumed releases, the factors which tend to mitigate the release of radioactivity, and the release paths are given in Appendix11.1A | |||
. A further discussion of the gaseous releases from the plant is provided in Section11.3.3 | |||

CALLAWAY - SP11.3-4Rev. OL-2211/1611.3.2.2ComponentDescriptionCodes and standards applicable to the GRWS are listed in Tables3.2-1 and 11.3-1. The GRWS is designed and constructed in accordance with quality groupD (augmented). The GRWS is seismically designed, as discussed in Table3.2-5. The GRWS is housed within a seismically designed building. The GRWS design complies with Regulatory Guide1.143, as specified in Table3.2-5 | |||
. WASTE GAS COMPRESSOR-The waste gas compressor is a water-sealed centrifugal displacement unit which maintains continuous circulation of nitrogen around the waste gas loop. The compressor is provided with a mechanical shaft seal to minimize water leakage. The compressor moisture separator normal water level is maintained to keep the shaft immersed at all times. Two waste gas compressor packages are provided. One compressor is normally used, and the other compressor is on standby. The packages are self-contained and skid-mounted. Construction is primarily of carbon steel. CATALYTIC HYDROGEN RECOMBINER-The catalytic recombiner disposes of hydrogen brought into the GRWS. This is accomplished by adding a controlled amount of oxygen to the recombiner which reacts with the hydrogen as the gas flows through a catalyst bed. The control system for the recombiner is designed to preclude the possibility of a hydrogen explosion. This is further discussed in Section11.3.6 | |||
. Two hydrogen recombiner packages are provided. One recombiner is normally used, and the other is on standby. The packages are self-contained and skid-mounted. The recombiner is located in the system where the hydrogen concentration and pressure are optimum with respect to hydrogen removal. DECAY TANK-Eight gas decay tanks are provided, six for normal power operation and two for service at shutdown and startup. The tanks are of the vertical-cylindrical type and are constructed of carbon steel. MISCELLANEOUS COMPONENTS-The gas decay drain collection tank provides a collection point for condensation drained from the gas decay tanks, recombiners, and gas compressors. All control valves, with the exception of those on the recombiner, are provided with bellow seals to minimize the leakage of radioactive gases through the valve bonnet and stem. Valves on the recombiner package are provided with leakoffs. Relief valves have soft seats and are exposed to pressures which are normally less than two-thirds of the relief valve set pressure. The relief valves of the major components discharge to the shutdown tanks. This permits decay and controlled disposal of all discharges less than about 3,000scf. The relief valves are designed to relieve full flow from both waste gas compressors. | |||
CALLAWAY - SP11.3-5Rev. OL-2211/16To maintain leakage from the system at the lowest practicable level, diaphragm-type manual valves are used throughout the waste gas system. For low temperature, low pressure service valves with a synthetic rubber-type diaphragm are used. This application includes all parts of the system, except the recombiners. Because of the high temperature that may exist in the recombiner, globe type valves with a metal diaphragm seal in the stem are used. There should be no measurable stem leakage from either type of valve. The gas decay tank drain pump directs water from the gas decay drain collection tank (due to condensation or maintenance) to the waste holdup tank or recycle holdup tanks. It is used when there is insufficient pressure in the gas system to drive the fluid. All parts of the pump in contact with the drain water are of austenitic stainless steel. The pump is a canned-motor type. The waste gas drain filter is a disposable cartridge filter provided to prevent particulate matter, including rust, larger than 30microns from entering the LRWS and BRS. All parts of the filter in contact with the drain water are of austenitic stainless steel. The waste gas traps are designed to prevent gases from leaving the GRWS. There are four gas traps-two in the gas decay tank drain line and one each in the recombiner drain lines and compressor drain lines. The component description for the ventilation systems is provided in Section9.4 | |||
. 11.3.2.3SystemOperationOperation of the ventilation systems is described in Section9.4. The following is a description of the GRWS. NORMAL OPERATION - The GRWS system is normally operated when increased fission gases or excess hydrogen levels have accumulated in the volume control tank (VCT). When needed, nitrogen gas, with contained fission gases, is circulated around the GRWS loop by one of the two compressors. Fresh hydrogen gas is introduced into the VCT where it is mixed with fission gases stripped from the reactor coolant by the action of the VCT letdown line spray nozzle. The gas is vented from the VCT into the circulating nitrogen in the waste gas system, at the compressor suction.The resulting mixture of nitrogen, hydrogen, and fission gases is pumped by one of the compressors to one of the two catalytic hydrogen recombiners where enough oxygen is added to react with and reduce the hydrogen to a low residual level. Water vapor formed in the recombiner by the hydrogen and oxygen reaction is condensed and removed, and the cooled gas stream (now composed primarily of nitrogen, helium, and fission gases) is discharged from the recombiner, routed through a gas decay tank, and sent back to the compressor suction to complete the loop circuit. Only one gas decay tank is valved into the waste gas loop at any time. | |||
CALLAWAY - SP11.3-6Rev. OL-2211/16If it has been determined that excessive nitrogen buildup is occurring within the system or when other occurrences require it, one tank can be valved out of service and allowed to decay for a period of 60days. If the holdup time restricts plant operation, it may be necessary to decrease this time with prior approval from the Manager, Radiation Protection.STARTUP-At plant startup, the system is first flushed free of air and filled with nitrogen at atmospheric pressure. One compressor, one recombiner, and one shutdown decay tank are in service. The reactor is at the cold shutdown condition. Fresh hydrogen is charged into the volume control tank, and the volume control tank vent gas mixes with the circulating nitrogen in the GRWS. This circulating mixture enters the compressor suction, passes through the recombiner and shutdown gas decay tank, and returns to the compressor suction. When the reactor coolant system hydrogen concentration is within operating specifications, the shutdown gas decay tank is isolated and the gas flow directed to one of the gas decay tanks provided for normal power operation. Gases accumulated in the shutdown tank will be retained for reuse during hydrogen stripping from the reactor coolant system during subsequent shutdown operations. SHUTDOWN AND DEGASSING OF THE REACTOR COOLANT SYSTEM-Plant shutdown operations are essentially startup operations in reverse sequence. During normal power operations a hydrogen purge is maintained on the VCT. After Reactor shutdown, a nitrogen purge to the VCT is begun from the nitrogen header or from a shutdown gas decay tank. A Gas Decay Tank is placed in the process loop so that the gas mixture from the VCT vents to the GRW system and passes through to the recombiner where hydrogen is removed. The volume control tank nitrogen purge is maintained until hydrogen and coolant fission gas concentrations have been reduced to specified levels. During this operation, nitrogen purge flow may be increased to speed up coolant degassing. During degas operations, the inlet Hydrogen analyzer may be bypassed to facilitate Hydrogen removal. Technical Specifications provide the limits to follow during analyzer operations. The nitrogen purge continues until the reactor coolant hydrogen concentration reaches the required level. Degassing is then complete, and the reactor coolant system may be opened for maintenance or refueling. An alternative method to degas the reactor coolant system may also be employed. This method, chemical degassing, reduces the reactor coolant dissolved hydrogen concentration through reaction with hydrogen peroxide. After Reactor shutdown, plant cooldown continues until RCS temperature is less than 180°F. A pre-determined quantity of hydrogen peroxide is added. The hydrogen peroxide reacts with dissolved hydrogen to form water. The reactor coolant is sampled to verify the hydrogen concentration has reached the required level. The VCT nitrogen purge may be performed in conjunction with chemical degas operations if it is desired to reduce reactor coolant system noble gas levels or to help expedite reducing the RCS hydrogen concentration. | CALLAWAY - SP11.3-6Rev.

SHUTDOWN AND DEGASSING OF THE REACTOR COOLANT SYSTEM-Plant shutdown operations are essentially startup operations in reverse sequence. During normal power operations a hydrogen purge is maintained on the VCT. After Reactor shutdown, a nitrogen purge to the VCT is begun from the nitrogen header or from a shutdown gas decay tank. A Gas Decay Tank is placed in the process loop so that the gas mixture from the VCT vents to the GRW system and passes through to the recombiner where hydrogen is removed. The volume control tank nitrogen purge is maintained until hydrogen and coolant fission gas concentrations have been reduced to specified levels. During this operation, nitrogen purge flow may be increased to speed up coolant degassing. During degas operations, the inlet Hydrogen analyzer may be bypassed to facilitate Hydrogen removal. Technical Specifications provide the limits to follow during analyzer operations. The nitrogen purge continues until the reactor coolant hydrogen concentration reaches the required level. Degassing is then complete, and the reactor coolant system may be opened for maintenance or refueling. An alternative method to degas the reactor coolant system may also be employed. This method, chemical degassing, reduces the reactor coolant dissolved hydrogen concentration through reaction with hydrogen peroxide. After Reactor shutdown, plant cooldown continues until RCS temperature is less than 180°F. A pre-determined quantity of hydrogen peroxide is added. The hydrogen peroxide reacts with dissolved hydrogen to form water. The reactor coolant is sampled to verify the hydrogen concentration has reached the required level. The VCT nitrogen purge may be performed in conjunction with chemical degas operations if it is desired to reduce reactor coolant system noble gas levels or to help expedite reducing the RCS hydrogen concentration. | ||

CALLAWAY - SP11.3-8Rev. OL-2211/1611.3.6INSTRUMENTATION APPLICATIONThe GRWS instrumentation, as described in Table11.3-3, is designed to facilitate automatic operation and remote control of the system and to provide continuous indication of system parameters. The instrumentation readout is located mainly on the waste processing system panel in the radwaste building. Some instruments are read where the equipment is located. All alarms are shown separately on the waste processing system panel. Where suitable, instrument lines are provided with diaphragm seals to prevent fission gas outleakage through the instrument. Figure11.3-3 shows the location of the instruments on the compressor package. The compressors are interlocked with the seal water inventory in the moisture separators and trip off on either high or low moisture separator level. During normal operation, the proper seal water inventory is maintained automatically. Figure11.3-4 indicates the location of the instruments on the recombiner installation. The catalytic recombiner system is designed for automatic operation with a minimum of operation attention. Each package includes two online gas analyzers, one to measure hydrogen and oxygen in and one to measure hydrogen and oxygen out, which are the primary means of recombiner control. Each gas concentration channel of these two online gas analyzers is independently controlled. The GRWS is designed to operate with hydrogen concentrations above 4 percent by volume. Flammable mixtures of gases in the system are prevented by monitoring and controlling the oxygen concentration to appropriate levels. The setpoints for oxygen concentration in the catalyst bed inlet stream are 3 percent for the hi alarm and 3.5 percent for the hi-hi alarm and isolation of the oxygen supply. The setpoint for oxygen concentration downstream of the catalyst bed is 60 ppm oxygen for the hi-hi alarm and isolation of inlet oxygen supply. Thus the oxygen supply to the recombiner would be terminated before the concentration in the GRWS would reach levels favorable for hydrogen flammability. Since the GRWS is designed to operate with hydrogen concentrations up to 6 percent by volume, up to 3 percent oxygen is necessary for operation of the catalytic recombiner. Termination of oxygen feed at 2 percent as suggested by regulatory guidance is inappropriate. Further, since the minimum oxygen concentration necessary to support combustion at 4 percent by volume hydrogen concentrations is 5 percent, the hi-alarm setpoint of 3 percent provides sufficient margin (i.e., 60percent of the limit) to flammability. A multipoint temperature recorder monitors temperatures at several locations in the recombiner packages. | CALLAWAY - SP11.3-8Rev.

: a.Solidification systemb.Dry waste system c.Resin handling systemd.Filter handling systemThe activity of the influents to the SRS is dependent on the activities of the various fluid systems, such as the boron recycle system, secondary liquid waste system, liquid waste management system, chemical and volume control system, fuel pool cooling and cleanup system, floor and equipment drain system, and the steam generator blowdown CALLAWAY - SP11.4-3Rev. OL-2211/16system. Reactor coolant system activities and the decontamination factors for the systems given above also determine the influent activities to the solid radwaste system. Table 11.4-2 lists the estimated expected and maximum activities of waste to be processed on an annual basis and their physical form and source. The isotopic makeup and curie contents of the expected influents to the SRS are given in Table 11.4-2. The estimated annual quantities of solid radwaste to be shipped offsite are presented in Table 11.4-3. The estimated expected and maximum curie and isotopic content of wastes to be shipped offsite for each waste category are also presented in Table 11.4-4 | |||
.Section 11.1 and Appendix 11.1A provided the bases for determination of liquid source terms which are used to calculate the solid waste source terms. The sources presented in Tables 11.4-2 and 11.4-4 are conservatively based on Section 11.1 | |||
, Appendix 11.1A and the following additional information: a.As a basis for the shipped-from-site activities given in Table 11.4-4, 30 days' decay prior to shipment is assumed. b.The miscellaneous dry and compacted waste volume is based on Case 6 of Table 2-49 of WASH-1258, July, 1973.c.Shipping volumes based on packaging in 55-gallon drums:(1)3.5 ft 3 primary spent resin, primary charcoal, per drum (2)4.8 ft 3 liquid radwaste processing spent resin and charcoal per drum(3) 1 filter cartridge per drum (4)7.5 ft 3 shipped volume per drum (including cement) 11.4.2.2ComponentDescriptionCodes and standards applicable to the SRS are listed in Tables 3.2-1 and 11.4-5. The SRS is designed and constructed in accordance with requirements. The SRS is housed within a seismically designed building. Regulatory Guide 1.143 is complied with to the extent specified in Table 3.2-5 | |||
. SRS component parameters are presented in Table 11.4-5. The following is a functional description of the major system components: SPENT RESIN STORAGE TANK (PRIMARY) - Provides for storage and decay of the spent resins from the demineralizers in the chemical and volume control system, fuel pool cooling and cleanup system, boron recycle system, and liquid radwaste system prior to dewatering processes. | |||
CALLAWAY - SP11.4-4Rev. OL-2211/16SPENT RESIN STORAGE TANK (SECONDARY) - Provides for storage and decay of the spent resins and spent activated charcoal from the demineralizers and charcoal adsorbers in the steam generator blowdown system, secondary liquid waste system, and charcoal adsorbers in the liquid radwaste system prior to solidification or dewatering processes. SPENT RESIN SLUICE PUMPS (PRIMARY AND SECONDARY) - Can provide the motive flow to transfer spent resin or spent activated charcoal from the various demineralizers or adsorbers to the appropriate spent resin storage tank. CAUSTIC ADDITION TANK AND METERING PUMP - Provides chemistry control to the chemical drain tank, floor drain tank, waste holdup tank, and discharge monitor tanks. RESIN CHARGING TANKS - Provide remote means of gravity sluicing clean resin and activated charcoal into the demineralizer and adsorber units. SOLID RADWASTE BRIDGE CRANE - A crane, remotely operated from the solid radwaste control console, which provides the means of moving containers from station to station in the processing area, from the processing area to the solid waste storage area, and from the solid waste storage area to the shipping area. The crane is equipped with a television camera system to facilitate the remote handling operation. | |||
BULK WASTE DISPOSAL STATION - Provides a means for bulk processing or disposal of wastes generated during plant operations. Process piping is provided within the installed solid radwaste system to allow the transfer of wastes contained within either of the evaporator bottoms tanks or spent resins storage tanks through the bulk waste processing packaging equipment.CHEMICAL ADDITION POT - The portable skid provides the flexibility to add various chemicals to the Radwaste systems and components as needed.11.4.2.3SystemOperation 11.4.2.3.1Solidification System Solids inputs to the solidification system, such as spent resins and charcoal, are sluiced to either the spent resin storage tank (primary) or spent resin storage tank (secondary), depending upon which component that supplied the waste. | |||
CALLAWAY - SP11.4-5Rev. OL-2211/16Solidification of process wastes is based upon formulas approved per the plant Process Control Program (PCP). These pretested formulas establish the system's process parameters and provide boundary conditions within which reasonable assurance is given that complete solidification (the lack of free water) has occurred. The boundary conditions for process parameters include mixing time, waste pH, major chemical substances, liquid waste-to-binder ratio, and solids-to-water ratio. The PCP establishes and defines the administrative controls which will be used and identifies the documentation necessary to ensure that the process is operated within the established boundaries. | |||
SPENT RESINS - The approximate volume that can be solidified in a 55-gallon drum is 3.5 cubic feet of primary spent resins and 4.8 cubic feet of secondary spent resins.SPENT ACTIVATED CHARCOAL - The approximate volume that can be solidified in a 55-gallon drum is 3.5 cubic feet primary spent charcoal and 4.8 cubic feet of secondary spent resins. FILTER CARTRIDGES - Where acceptable per the applicable NRC, DOT, and state regulations, filter cartridges which may be disposed of without stabilization, may be packaged in common drums with up to 12 cartridges per drum or placed within a Low Specific Activity (LSA) box. Filter cartridges requiring stabilization for disposal, will be packaged in individual 55-gallon drums or in approved High Integrity Containers.MISCELLANEOUS DRY WASTES - Miscellaneous paper, clothing, etc., are assumed to have the volume reduced by a factor of five in the compactor, which is a commercially available hydraulic press. 11.4.2.3.2Dry Waste System Low-level dry active wastes are collected at appropriate locations throughout the plant, as dictated by the volume of these wastes generated during operation or maintenance. | |||
Dry wastes, which can be compressed to minimize the shipping volume, may be compacted in 55-gallon drums with a dry waste compactor or may be packaged in approved containers for offsite volume reduction. Compactors are located in the radwaste building, and auxiliary building. The dry waste compactors have an integral shroud which directs any airborne dusts created by the compaction operation through an exhaust fan and filter, and then to the respective building's ventilation system. Packaged containers are sealed and moved either to the drum storage area in the radwaste building, fenced radwaste yards, or to another approved storage location, where they are stored until shipment offsite. | Dry wastes, which can be compressed to minimize the shipping volume, may be compacted in 55-gallon drums with a dry waste compactor or may be packaged in approved containers for offsite volume reduction.

11.4.2.3.3Resin Handling System The resin handling system provides the capability for remote removal of spent radioactive resin and activated charcoal from the demineralizer and charcoal adsorber vessels in the chemical and volume control system, fuel pool cooling and cleanup system, boron recycle system, liquid radwaste system, steam generator blowdown system, and secondary liquid waste system and to transfer them to the associated spent resin storage tank or bulk waste disposal station. In the resin transfer mode, the spent resin sluice pumps take suction from the storage tank via a screened connection on the tank and pump water through the respective vessel to first backflush the resin and then sluice the resin to the spent resin storage tank. Primary resin may be also sluiced from the demineralizer vessel to the primary spent resin storage tank with reactor makeup water. Steam generator blowdown resin may be sluiced from the demineralizer vessel to the secondary spent resin storage tank with reactor makeup water. Primary resin or steam generator blowdown resins may also be sluiced directly to the bulk waste disposal station with reactor makeup water. Positive indication that the resin has been sluiced to the spent resin storage tank or bulk waste disposal station is provided by an radiation measuring instrumentation located in the spent resin sluice header or by visually monitoring the bulk waste container.The spent resin storage tank (primary), which accepts spent resins from waste processing systems, is capable of accommodating at least 60 days' waste generation at normal generation rates. The spent resin storage tank (secondary), which accepts spent resin and spent activated charcoal from the remaining vessels, is capable of accommodating at least 30-days' waste generation at normal generation rates. Spent resin and spent activated charcoal are transferred from the spent resin storage tanks to the bulk waste disposal station by pressurizing the storage tank with nitrogen and supplying sluice water at the outlet nozzle on the tank for bulk waste processing. The empty demineralizer or charcoal adsorber vessels are filled with clean media by gravity sluicing from the resin charging tank or by pumping a slurry directly from the new CALLAWAY - SP11.4-7Rev. OL-2211/16media container into the associated vessels. The filling operations are performed remotely from the vessels being filled. 11.4.2.3.4Filter Handling System Filter cartridge changeouts are to be performed utilizing manual changeout techniques.11.4.2.4Bulk Waste Disposal Bulk waste disposal, as the name implies, involves the processing of large volumes of waste via bulk processing means for subsequent disposal. | |||

Bulk waste disposal, as the name implies, involves the processing of large volumes of waste via bulk processing means for subsequent disposal. | |||
The bulk waste disposal station consists of a set of flanged connections installed in a common crossover leg of the solid radwaste system process piping through which spent resin/spent activated charcoal from the spent resins storage tanks may be transferred. Piping or hose connections are made between the bulk waste disposal station waste transfer flange and either a vendor processing skid or directly to an appropriate container such as a liner or a High Integrity Container (HIC). Hoses and/or piping utilized are subjected to pressure tests to verify leak-tight connections and adequacy of the hose or pipe to safely contain and transport the waste. | The bulk waste disposal station consists of a set of flanged connections installed in a common crossover leg of the solid radwaste system process piping through which spent resin/spent activated charcoal from the spent resins storage tanks may be transferred.

CALLAWAY - SP11.4-8Rev. OL-2211/1611.4.2.5Packaging,Storage,andShipment Spent resins, spent charcoal, spent filter cartridges, and solid compactable wastes such as paper, rags, and clothing are packaged in approved containers, in accordance with 49 CFR, and shipped in shielded casks, as required to meet 49CFRdose limitations. Packaged solid radwaste is normally stored in one of two locations, depending on the requirements for radiation shielding and the amounts of waste temporarily stored onsite. These two locations are designated drummed and bulk solid radwaste storage locations. The storage location for drummed solid radwaste is an annex to the radwaste building, on the south side, as shown in Figure 1.2-3. This storage area includes shielding cubicles for the storage of high level waste such as spent resins and filters. Other containers of radwaste may also be stored in this area. This structure (i.e., the annex to the radwaste building) has concrete walls for radiation shielding. Within this structure are two storage areas, containing 550 and 1,180 square feet of usable floor area. These areas are shielded and remotely maintained to limit radiation exposure to operating personnel. On the basis of stacking the filled drums 5 levels high, the drum capacities of the two areas are 395 and 1,055 drums, pyramidal, or 585 and 1,365 drums, palletized.

Based on this estimate, there is capacity in the radwaste building for approximately 2 years of drummed solid wastes.The storage location for bulk solid radwaste is normally in the outside area adjacent to the drummed storage annex section of the Radwaste Building, on the Plant West side of the building, extending Plant South to the Discharge Monitoring Tank area. This storage area is provided with a concrete slab surface for placement of containers, and is enclosed by a fence with access gates, for control of access to the area. Packaged solid radwaste, in HICs, Boxes or DOT approved shipping containers, is temporarily stored in this or other approved locations onsite while awaiting shipment to an off-site treatment or disposal facility, or for radioactive decay prior to long term storage within a facility structure. | -Dry wastesIt is estimated that the maximum total of these wastes will be 923 drums per year (refer to Table 11.4-3).

CALLAWAY - SP11.4-9Rev. OL-2211/16While no protection from the environmental elements is afforded to the packaged radwaste containers stored in outside locations, the containers used for packaging these wastes are DOT approved containers for shipment. These containers are designed and manufactured to meet the conditions incident to shipping and disposal. On-site storage containers will be used for interim storage of high integrity containers. Refer to Table 11.4-3 for Estimated Maximum Annual Quantities of Solid Radwaste.11.4.3SAFETY EVALUATION The containers that require radiation shielding are stored in the radwaste building, which is resistant to tornadoes. These drums will remain in place during any extreme environmental event. The drums or other approved shipping containers for noncompacted, dry wastes, etc., stored outside in bulk storage have low specific activities and, thus, even if dispersed by a tornado do not pose a radiation risk to onsite or off site personnel. The drummed radwaste storage area protects the containers from rainfall and corrosion. As described in Chapter 2.0, flooding is not a potential concern in grade-level buildings at the Callaway site. Although wastes are expected to be stored onsite for some period of time prior to shipment, normally no credit other than 30-day decay will be taken for radioactive decay realized by such storage when filling containers for shipping in accordance with 49 CFR dose limitations. That is, once filled, containers can normally be shipped immediately, subject to availability of a disposal site, with the proper shielding, without exceeding Department of Transportation radiation limits. If 49 CFR dose limitations cannot be met with the available shielding, however, the applicable containers are stored in appropriate storage areas until the doses are acceptable for shipping in accordance with Department of Transportation requirements. The minimum onsite residence time for low level solid radwaste prior to shipping, such as dry compacted waste, steam generator blowdown spent resins, and spent charcoal, ranges from several days to a few months. The minimum onsite residence time for solid radwaste prior to shipping, such as primary spent resins and spent filter cartridges from the primary system, ranges from a few months to a few years. Onsite residence time is based on the initial activity of the container, the time required to have sufficient containers to completely load a transporting vehicle, the thickness of the shields available, the number of containers which can be stored in the available shipping casks, the availability of a transporting vehicle, and the availability of ultimate disposal facilities. All solid radwaste is shipped from the site in Department of Transportation-approved containers by Department of Transportation-approved carriers. Containers with any CALLAWAY - SP11.4-10Rev. OL-2211/16significant surface dose rate are moved remotely from the shielded storage areas to the transporting vehicle.Radiation measurements made at the time of shipment of any radioactive waste material ensure that all shipments leave the site well within prescribed limits. Similarly, external contamination measurements are made to detect any potential release of radioactive material from the container prior to shipment.11.4.4TESTS AND INSPECTIONS The SRS is in intermittent use throughout normal reactor operation. Periodic visual inspection and preventative maintenance are conducted using normal industry practice. Refer to Chapter 14.0 for further information. 11.4.5INSTRUMENTATION APPLICATION Two control panels are provided for the equipment in the SRS which contains or processes potentially radioactive fluids or slurries. One control panel is located in the radwaste building control room and contains the instrumentation for the equipment which interfaces the influent systems (i.e., spent resin storage tank - primary, and spent resin storage tank - secondary) and for the equipment used for process control (i.e., caustic addition tank, and caustic addition metering pump). The second control panel (solidification control panel) is located in a separate room in close proximity to the solidification processing area. The control panel contains all instrumentation, including television monitors, required for transferring waste to the bulk waste disposal station. Pertinent instruments and controls for the transferring of the wastes from the tanks containing the wastes are duplicated on this panel so that the solid radwaste solidification system operator can transfer the waste from these tanks to the bulk waste disposal station. | CALLAWAY - SP11.4-9Rev.

Dry waste compactors are designed with ventilation shroud exhaust fan and filter to control the airborne dust during the compaction process.b.Activated charcoal, HEPA filters, and other dry wastes which do not normally require solidification processing should be treated as radioactively contaminated solids and packaged for disposal in accordance with applicable Federal regulations.I.1.bComplies.2.Wet Wastesa.Wet wastes such as spent bead and powdered resins and filter sludge should be rendered immobile by combining with a suitable binding agency (cement, urea formaldehyde, asphalt, etc.) to form a homogenous solid matrix (absent of free water) prior to offsite shipment. Absorbents such as vermiculite are not acceptable substitutes for binding agents.I.2.aComplies. Packaging of radioactive filter sludge complies in that these wastes will be combined with a suitable binding agent (e.g., cement) to form a homogeneous solid matrix prior to offsite shipment. Packaging of radioactive spent demineralizer resins also complies (resins may be combined with a suitable binding agent to create a homogeneous solid matrix prior to offsite shipment) except that they may be packaged by dewatering in a steel liner or High Integrity Container per the requirements of 10CFR61, prior to offsite shipment. Absorbent will not be used as a substitute for a binding agent for wastes requiring immobilization. Waste not requiring immobilization will be packaged using acceptable methods approved by DOT and burial site requirements.b.Spent cartridge filter elements may be packaged in a shielded container with a suitable absorber such as vermiculite, although it would be desirable to solidify the elements in a suitable binder.I.2.bComplies.II.ASSURANCE OF COMPLETE SOLIDIFICATIONComplete solidification of wet wastes should be assured by the implementation of a process control program or by methods to detect free liquids within container contents prior to shipment.1.Process Control Program CALLAWAY - SPTABLE 11.4-1 (Sheet 2)Rev. OL-155/06a.Solidification (binding) agents and potential waste constituents should be tested and a set of process parameters (pH, ratio of waste to agent, etc.) established which provide boundary conditions within which reasonable assurance can be given that solidification will be complete.II.1.aComplies. Solidification formula demonstrating complete solidification for the expected wastes is determined by shop tests. These tests provide the boundary condition within which reasonable assurance is given that complete solidification, i.e., lack of free water, has occurred.b.The solid waste processing system (or liquid waste processing system, as appropriate) should include appropriate instrumentation and wet waste sampling capability necessary to successfully implement and/or verify the process control program described in a., above.II.1.bComplies. Sample provisions exist for the determination of chemical constituents to be solidified. In addition, pH adjustments can be made to optimize solidification operations.c.The plant operator should provide assurance that the process is run within the parameters established under a., above. Appropriate records should be maintained for individual batches showing conformance with the established parameters.II.1.cComplies. Administrative controls will be used and records will be maintained to ensure that the process is operated within the established boundaries.2.Free Liquid DetectionEach container filled with solidified wet wastes should be checked by suitable methods to verify the absence of free liquids. Visual inspection of the upper surface of the waste in the container is not alone sufficient to ensure that free water is not present in the container. Provisions to be used to verify the absence of free liquids should consider actual solidification procedures which may create a thin layer of solidification agent on top without affecting the lower portion of the container.II.2The shop-tested solidification formula coupled with the administrative controls assure the absence of free liquids.III.WASTE STORAGE1.Tanks accumulating spent resins from reactor water purification systems should be capable of accommodating at least 60 days waste generation at normal generation rates. Tanks accumulating spent resins from other sources and tanks accumulating filter sludges should be capable of accommodating at least 30 days waste generation at normal generation rates.III.1Complies.2.Storage areas for solidified wastes should be capable of accommodating at least 30 days waste generation at normal generation rates. These storage areas should be located indoors.III.2Complies.

Dry waste compactors are designed with ventilation shroud exhaust fan and filter to control the airborne dust during the compaction process.b.Activated charcoal, HEPA filters, and other dry wastes which do not normally require solidification processing should be treated as radioactively contaminated solids and packaged for disposal in accordance with applicable Federal regulations.I.1.bComplies.2.Wet Wastesa.Wet wastes such as spent bead and powdered resins and filter sludge should be rendered immobile by combining with a suitable binding agency (cement, urea formaldehyde, asphalt, etc.) to form a homogenous solid matrix (absent of free water) prior to offsite shipment. Absorbents such as vermiculite are not acceptable substitutes for binding agents.I.2.aComplies. Packaging of radioactive filter sludge complies in that these wastes will be combined with a suitable binding agent (e.g., cement) to form a homogeneous solid matrix prior to offsite shipment. Packaging of radioactive spent demineralizer resins also complies (resins may be combined with a suitable binding agent to create a homogeneous solid matrix prior to offsite shipment) except that they may be packaged by dewatering in a steel liner or High Integrity Container per the requirements of 10CFR61, prior to offsite shipment. Absorbent will not be used as a substitute for a binding agent for wastes requiring immobilization. Waste not requiring immobilization will be packaged using acceptable methods approved by DOT and burial site requirements.b.Spent cartridge filter elements may be packaged in a shielded container with a suitable absorber such as vermiculite, although it would be desirable to solidify the elements in a suitable binder.I.2.bComplies.II.ASSURANCE OF COMPLETE SOLIDIFICATIONComplete solidification of wet wastes should be assured by the implementation of a process control program or by methods to detect free liquids within container contents prior to shipment.1.Process Control Program CALLAWAY - SPTABLE 11.4-1 (Sheet 2)Rev. OL-155/06a.Solidification (binding) agents and potential waste constituents should be tested and a set of process parameters (pH, ratio of waste to agent, etc.) established which provide boundary conditions within which reasonable assurance can be given that solidification will be complete.II.1.aComplies. Solidification formula demonstrating complete solidification for the expected wastes is determined by shop tests. These tests provide the boundary condition within which reasonable assurance is given that complete solidification, i.e., lack of free water, has occurred.b.The solid waste processing system (or liquid waste processing system, as appropriate) should include appropriate instrumentation and wet waste sampling capability necessary to successfully implement and/or verify the process control program described in a., above.II.1.bComplies. Sample provisions exist for the determination of chemical constituents to be solidified. In addition, pH adjustments can be made to optimize solidification operations.c.The plant operator should provide assurance that the process is run within the parameters established under a., above. Appropriate records should be maintained for individual batches showing conformance with the established parameters.II.1.cComplies. Administrative controls will be used and records will be maintained to ensure that the process is operated within the established boundaries.2.Free Liquid DetectionEach container filled with solidified wet wastes should be checked by suitable methods to verify the absence of free liquids. Visual inspection of the upper surface of the waste in the container is not alone sufficient to ensure that free water is not present in the container. Provisions to be used to verify the absence of free liquids should consider actual solidification procedures which may create a thin layer of solidification agent on top without affecting the lower portion of the container.II.2The shop-tested solidification formula coupled with the administrative controls assure the absence of free liquids.III.WASTE STORAGE1.Tanks accumulating spent resins from reactor water purification systems should be capable of accommodating at least 60 days waste generation at normal generation rates. Tanks accumulating spent resins from other sources and tanks accumulating filter sludges should be capable of accommodating at least 30 days waste generation at normal generation rates.III.1Complies.2.Storage areas for solidified wastes should be capable of accommodating at least 30 days waste generation at normal generation rates. These storage areas should be located indoors.III.2Complies. Outside storage of packaged radwaste staged for shipment or decay is administratively controlled in approved onsite storage locations.3.Storage areas for dry wastes and packaged contaminated equipment should be capable of accommodating at least one full offsite waste shipment.III.3Complies.ETSB 11-3 POSITIONUNION ELECTRIC POSITION CALLAWAY - SPTABLE 11.4-1 (Sheet 3)Rev.

CALLAWAY - SP11.5-1Rev. OL-195/1211.5PROCESS AND EFFLUENT RADIOLOGICAL MONITORING AND SAMPLINGSYSTEMSThe function of the process and effluent radiological monitoring systems is to monitor, record, and control the release of radioactive materials that may be generated during normal operation, anticipated operational occurrences, and postulated accidents. The process and effluent radioactivity monitoring systems furnish information to operations personnel concerning radioactivity levels in principal plant process streams and atmospheres. The monitoring systems indicate and alarm excessive radioactivity levels (GDC-63). They initiate operation of standby systems, provide inputs to the ventilation and liquid discharge isolation systems, and record the rate of release of radioactive materials to the environs, as outlined in Regulatory Guide 1.21 and GDCs 60 and 64. The systems consist of permanently installed, continuous-monitoring devices together with a program and provisions for specific sample collections and laboratory analyses. 11.5.1DESIGN BASES The principal objectives and criteria of the process and effluent radiological monitoring systems are provided below. 11.5.1.1SafetyDesignBasesSAFETY DESIGN BASES - The control room ventilation monitors, the containment purge monitors, and the fuel building exhaust monitors are designed to activate engineered safety features systems in the event that airborne radioactivity in excess of allowable limits exists. Additional design bases are stated in the following sections:a.Containment purge isolation system, Sections 6.2.4, 7.3.2, 9.4.6, and 12.3.4. b.Fuel building ventilation isolation, Sections 7.3.3, 9.4.2, and 12.3.4. c.Control room intake isolation, Sections 6.4.1, 7.3.4, 9.4.1, and 12.3.4.

OL-195/1211.5.1.2PowerGenerationDesignBasesPOWER GENERATION DESIGN BASIS ONE - The process and effluent radioactivity monitors operate continuously during both intermittent and continuous discharges of potentially radioactive plant effluents, in compliance with Regulatory Guide 1.21. The monitors verify that the most restrictive anticipated nuclides are at concentrations within the limits specified in Table II of Appendix B of 10 CFR 20 and that the concentrations are low enough that 10 CFR 50 Appendix I dose guidelines are met for unrestricted areas. POWER GENERATION DESIGN BASIS TWO - The process and effluent radioactivity monitors alarm and automatically terminate the release of effluents when radionuclide concentrations exceed the limits specified (GDC-60). Where termination of releases is not feasible, the monitors provide continuous indication of the magnitude of the activity released. POWER GENERATION DESIGN BASIS THREE - The radwaste process system monitors measure radioactivity in process streams to aid personnel in the treatment of radioactive fluids prior to recycle or discharge (GDC-63). POWER GENERATION DESIGN BASIS FOUR - The process and effluent radioactivity monitors monitor the containment atmosphere, spaces containing components for recirculation of LOCA fluids, effluent discharge paths, and for radioactivity that may be released from postulated accidents, as required by GDC-64. POWER GENERATION DESIGN BASIS FIVE - The process and effluent monitors indicate the existence and, to the extent possible, the magnitude of reactor coolant and reactor auxiliary system leakage to the containment atmosphere, cooling water systems, or the secondary side of the steam generators. POWER GENERATION DESIGN BASIS SIX - The process and effluent radioactivity monitors provide alarm and automatic termination of the transfer of radioactivity fluids to storage facilities in zone A areas, defined in Section 12.4.1.1. POWER GENERATION DESIGN BASIS SEVEN - Process radioactivity monitors provide alarm and gross indication of the extent of any failed fuel within the primary system. POWER GENERATION DESIGN BASIS EIGHT - The effluent radioactivity monitors provide sufficient radioactivity release data to prepare the reports required by Regulatory Guide1.21. | °F200MaterialAustenitic stainless steelDesign codeASME Sec.

CALLAWAY - SP11.5-2Rev. OL-195/1211.5.1.2PowerGenerationDesignBasesPOWER GENERATION DESIGN BASIS ONE - The process and effluent radioactivity monitors operate continuously during both intermittent and continuous discharges of potentially radioactive plant effluents, in compliance with Regulatory Guide 1.21. The monitors verify that the most restrictive anticipated nuclides are at concentrations within the limits specified in Table II of Appendix B of 10 CFR 20 and that the concentrations are low enough that 10 CFR 50 Appendix I dose guidelines are met for unrestricted areas. POWER GENERATION DESIGN BASIS TWO - The process and effluent radioactivity monitors alarm and automatically terminate the release of effluents when radionuclide concentrations exceed the limits specified (GDC-60). Where termination of releases is not feasible, the monitors provide continuous indication of the magnitude of the activity released. POWER GENERATION DESIGN BASIS THREE - The radwaste process system monitors measure radioactivity in process streams to aid personnel in the treatment of radioactive fluids prior to recycle or discharge (GDC-63). POWER GENERATION DESIGN BASIS FOUR - The process and effluent radioactivity monitors monitor the containment atmosphere, spaces containing components for recirculation of LOCA fluids, effluent discharge paths, and for radioactivity that may be released from postulated accidents, as required by GDC-64. POWER GENERATION DESIGN BASIS FIVE - The process and effluent monitors indicate the existence and, to the extent possible, the magnitude of reactor coolant and reactor auxiliary system leakage to the containment atmosphere, cooling water systems, or the secondary side of the steam generators.

Systems whose sensitivity is dependent upon sample flow employ isokinetic nozzles and suitable control of flow rate. 11.5.2.3.1.3Detection CriteriaSince both radioactive particulates and radioactive noble gases are beta emitters, beta sensitive scintillation detectors are used to sense radioactivity in order to minimize the effects due to background radiation and, consequently, obtain a lower minimum detectable concentration. The Laundry Decon Facility Dryer Exhaust Monitor uses a Geiger-Mueller counter.Where spectrometric analysis is required (such as in iodine monitoring) an NaI(Tl), gamma scintillation detector assembly is employed. | ||

The source terms used for releases, shielding, and accident analyses are based on 0.12, 0.25, and 1.0 percent fuel defects, respectively. 11.1.1RADIOACTIVE CONCENTRATIONS AND RELEASES Reactor coolant and secondary coolant specific activities for an assumed 0.12-percent fuel defects and an assumed 100pounds per day primary-to-secondary leakage are listed in Table11.1-1. These activities are used for calculational purposes only and may not represent actual reactor coolant and secondary coolant specific activities. Actual concentrations vary depending on plant conditions at any particular time. The basis for calculating these sources is Regulatory Guide 1.112. Compliance with Regulatory Guide 1.112 is discussed in Table 11.1-3
. Appendix 11.1A provides a comparison of the input used for the GALE Code with the generic input identified in the GALE Code. The decontamination factors applied are based on Regulatory Guide 1.112. A description of liquid leakage rates, process paths, and associated component activity levels is contained in Section 11.2 and Appendix 11.1A. A description of gaseous leakage rates, process paths, and associated activity levels is contained in Appendix 11.1A and Sections 11.3 and 9.4. In-plant airborne activity concentrations and other data regarding the ventilation systems are provided in Sections 12.3 and 12.4. Prior to the licensing and operation of a nuclear power plant, the applicant includes an estimate of the radioactive effluents and the resulting public doses in FSAR Chapter 11 per the requirements contained in 10 CFR 50.34(b)(3). This is provided to ensure the proposed radwaste treatment systems will be sufficient to ensure compliance with radioactive release criteria specified in 10 CFR 20 and 10 CFR 50 Appendix I (or RM50-2 for Callaway). The assessments presented in Chapter 11.1 are based on nominal assumptions and generic models that were appropriate at the time the original FSAR was written. They represent assumptions chosen for the purpose of estimating public dose consequences. They do not represent design or operational requirements. Actual operational data or system usage is expected to vary from the chosen assumptions, and may be more or less conservative than the assumptions presented in Chapter 11.1
.During operation, compliance with effluent release limits is ensured and controlled by compliance with FSAR Chapter 16 and the Offsite Dose Calculation Manual (ODCM). Chapter 16 and the ODCM provide detailed controls on effluent limits (both concentration and dose limits), monitoring requirements and performance of dose calculations. They also require operation of radwaste treatment equipment, if the projected dose exceeds a CALLAWAY - SP11.1-2HISTORICALsmall fraction of effluent ALARA guidelines. If effluent ALARA release guidelines are exceeded, or if treatment equipment is not operated when necessary, special reports to the NRC are required. These reports must provide the corrective actions being taken to ensure the guidelines are not exceeded in the future. Chapter 16 and the ODCM require the use of actual measured concentrations of radioactivity released to verify compliance with effluent limits. Compliance with effluent limits is verified frequently during the year.
Assuming operation within the Chapter 16 limits on primary coolant activity, it would take a long enough time to approach the limits such that the routine verifications will provide sufficient advanced indication to allow for corrective actions. Such corrective actions would ensure all annual dose limits are met.Therefore, compliance with effluent limits and regulations is controlled by Chapter 16 and the ODCM, not by meeting parameters or assumptions provided in Chapter 11.1. The assessments provided in Chapter 11.1 are a historical perspective of the basis behind the original radwaste system design. It was not the intent to operate within the bounds of each detailed assumption. As such, the parameters in Chapter 11.1 related to estimates of public dose from effluents are not updated, nor would it be useful to compare such parameters to actual plant operation. A more accurate and useful assessment of effluent levels and the public dose from effluents can be determined by referencing the Annual Radiological Effluent Report, Annual Radiological Environmental Monitoring Report and the routine estimates of dose required by the ODCM.When there are proposed changes to plant design, the LIR required per APA-ZZ-00140 for the modification process requires an evaluation of the potential effects on normal radiological effluents. If the initial screening determines that there may be some effect, a more detailed Final Environmental Evaluation may look at the parameters in Chapter 11.1 for a historical basis, but the review primarily considers the effects of the change on the actual measured effluents and the ability to meet the requirements of Chapter 16 and the ODCM. Informaton describing the Radioactive Waste Handling Systems required by 10 CFR 50.34(b)(2)(i) is addressed in FSAR Sections 11.2 and 11.3. These FSAR sections are not designated "historical" and will be updated as system modifications are made.Regulatory Guide 1.70, Revision 3, "Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants
," Section 11.1 requires that certain information on the sources and releases of radioactivity that serve as design bases for the various radioactive waste treatment systems be included in the PSAR including, mathematical models and parameters used to calculate source terms. Regulatory Guide 1.70 further requires that the FSAR should provide additional information required to update the PSAR to the final design conditions. Further, AmerenUE is committed to Regulatory Guide 1.181 which endorses NEI 98-03, Revision 1 "Guidelines for Updating Final Safety Analysis Reports." Section A3 of NEI 98-03 states that "Historical information provided in the original FSAR may have become out-of-date and is not expected to be used to support current or future plant operations or regulatory activities. Accordingly, it may be appropriate to reformat such information to distinguish it from UFSAR information actively maintained by licensees to describe the updated plant design and operation."
CALLAWAY - SP11.1-3HISTORICALWhile information regarding originally estimated source terms in FSAR Section 11.1 will remain in the FSAR, it will be designed as historical in accordance with NEI 98-03. Regulatory Guide 1.70 does not provide for the designation of FSAR information as historical. Therefore, an exception to Regulatory Guide 1.70 is taken in this regard and is noted in Table 3A-1
.11.1.2SHIELDING Reactor coolant and secondary coolant source terms used for shielding are based on 0.25-percent fuel defects. The source terms and the parameters used to calculate the source terms are given in Table 11.1-4 and Appendix 11.1A, respectively. Table 11.1-6 provides the isotopic composition of the contained sources for radioactive waste management systems and for large, potentially radioactive outside storage tanks. 11.1.3ACCIDENT ANALYSIS SOURCE TERMS Source terms used in accident analysis are based on assumptions presented in Section 15.0.9 and in the sections discussing individual analyses.

For gaseous effluents, such measures could include storage for decay of noble gases removed from the primary coolant and charcoal adsorbers or HEPA filters to remove radioiodine and radioactive particulates released from building ventilation exhaust systems. For liquid effluents, such measures could include storage for decay, demineralization, reverse osmosis, and evaporation.1.Inclusion of inplant control measures to maintain radioactive releases as low as is reasonably achievable has been incorporated in the design.2.The method of calculation described in NUREG-0016 and NUREG-0017 and the parameters presented in Chapter 2 of each report should be used to calculate the quantities of radioactive materials in gaseous and liquid effluents from light-water-cooled nuclear power reactors.2.Parameters of NUREG-0017 are used as discussed in Appendix 11.1A. The method of calculation described in NUREG-0017 has been generally followed.3.If methods and parameters used in calculating source terms are different from those given in NUREG-0016 and NUREG-0017, they should be described in detail and in the Environmental Report the basis for the methods and parameters used should be provided.3.Justification for use of assumptions other than those used in NUREG-0017 are provided in Appendix 11.1A

The following parameters and models are used to calculate radioactive source terms for the evaluation of radioactive waste treatment systems in determining the impact of radioactive effluents on the environment. Except where indicated and justified, the source terms are calculated using the PWR-GALE Code. Figure 11.1A-1 shows a block diagram of liquid releases, and Table 11.1A-2 and Figure 11.1A-2 provide the volume, radioactivity level, and decontamination factors (DF) for each liquid path. The values shown are for the standard power block design with an anion bed recycle evaporator condensate demineralizer. A mixed bed demineralizer is optional. See Chapter11.0 of the Site Addendum for the type used and any associated variations in the radioactive release values. Figure 11.1A-3 shows a block diagram of gaseous releases, and Tables 11.1A-3 and 11.1A-4 provide the volume, radioactivity level, and DF for each gaseous path. 11.1A.2The basic plant data for the source term calculations are provided in Table 11.1A-1. Table 11.1A-5 provides summary GALE Code input data. The following sections discuss the detailed design of waste systems:The plant ventilation systems are discussed in Section 9.4

OL-2011/1311.2LIQUIDWASTEMANAGEMENTSYSTEMS Several systems within the plant serve to control, collect, process, handle, store, recycle, and dispose of liquid radioactive waste generated as a result of normal plant operation, including anticipated operational occurrences. This section discusses the design and operating features and performance of the liquid radwaste system and the performance of other liquid waste management systems which are discussed in other sections. 11.2.1DESIGN BASES 11.2.1.1SafetyDesignBasis Except for two containment penetrations and the component cooling water side of the reactor coolant drain tank heat exchanger, the liquid radwaste system (LRWS) is not a safety-related system. SAFETY DESIGN BASIS ONE - The containment isolation valves in the LRWS are selected, tested, and located in accordance with the requirements of 10 CFR 50, Appendix A, GDC-56, and 10 CFR 50, Appendix J, Type C testing. 11.2.1.2PowerGenerationDesignBasesPOWER GENERATION BASIS ONE - The LRWS, in conjunction with other liquid waste management systems, is designed to meet the requirements of the discharge concentration limits of 10 CFR20 and the ALARA dose objective of 10 CFR 50, Appendix I. POWER GENERATION DESIGN BASIS TWO - The LRWS uses design and fabrication codes consistent with quality group D (augmented), as assigned by Regulatory Guide 1.143, for radioactive waste management systems. POWER GENERATION DESIGN BASIS THREE - Liquid effluent discharge paths are monitored for radioactivity. 11.2.2SYSTEM DESCRIPTION 11.2.2.1GeneralDescription This section describes the design and operating features of the LRWS. The performanceof the LRWS, in conjunction with other liquid waste management systems, is discussed in Section 11.2.3. Detailed descriptions of other liquid waste management systems are provided in the following sections: a.Boron recycle9.3.6b.Steam generator blowdown10.4.8 CALLAWAY - SP11.2-2Rev. OL-2011/13The piping and instrumentation diagram for the LRWS is shown in Figure 11.2-1
. The LRWS collects, processes, and discharges water entering the system. Equipment drains and waste streams are normally segregated to prevent the intermixing of the liquid wastes. The LRWS is capable of processing plant effluent for recycling reactor grade water, however, normally no tritiated water is transferred to the Reactor Makeup Water Storage Tank (RMWST). This method of operation prevents the contamination of Secondary systems due to deoxygenating the Reactor Makeup Water System (BL) water using the Demineralized Water Makeup Storage and Transfer System (AN).The LRWS consists of five waste collection subsystems and three waste processing subsystems:a.tritiated waste (CRW) drain subsystemb.potentially radioactive nontritiated waste (DRW) drain subsystemc.the Reactor Coolant Drain Tank subsystem (RCDT)d.the Chemical Waste subsysteme.the Laundry Waste subsystem f.the Liquid Radwaste Treatment subsystem (LRWTS)g.the Alternate Liquid Radwaste Treatment subsystemh.the Discharge Monitor Tank subsystemTritiated wastes (CRW), potentially radioactive nontritiated waste (DRW) and laundry waste drainage are discussed in Section 9.3.3
.The various waste streams are processed as follows:CRW SUBSYSTEM INFLUENTS - The CRW system processes all water that can be recycled. The CRW influents consist of reactor coolant which has been exposed to the atmosphere and has become aerated. This waste consists of equipment drains, leakoffs, and overflows from tritiated systems (e.g., CVCS and reactor coolant samples which have not been chemically contaminated). c.CVCS boron thermal regeneration and purification9.3.4d.Secondary liquid waste10.4.10 CALLAWAY - SP11.2-3Rev. OL-2011/13This waste is typically collected in the floor and equipment drain system and then transferred to the waste holdup tank. CRW influents are normally processed using the LRWTS and discharged from the plant.DRW SUBSYSTEM INFLUENTS - DRW influents are miscellaneous liquid wastes collected by the floor drain system within the radiologically controlled areas of the plant. The controlled access areas are radiation zones B through E and include the containment, auxiliary building, fuel building, radwaste building, and the access control areas of the control building.Floor drainage consists of miscellaneous leakage from systems within the above areas. Generally, the amount of highly radioactive reactor coolant leakage into the drain system is very small. The bulk of the water originates as leakage from nonradioactive or slightly radioactive systems, such as the service water and component cooling water systems. In addition to system leakage, the floor drain systems will collect decontamination water used for area washdowns, spent fuel cask decontamination, and laboratory equipment decontamination and rinses. Highly chemically contaminated decontamination solutions are normally not allowed to enter the floor drain system. During maintenance, equipment drains from nontritiated systems will normally be directed to the floor drain system. Large volumes of component cooling water will not normally be drained to the floor drain system to prevent contamination of the LRWS by corrosion inhibitors. DRW influents are collected in two floor drain tanks and are normally processed using the LRWTS and discharged from the plant.REACTOR COOLANT DRAIN TANK WASTE (RCDT) - Sources of water entering the reactor coolant drain tank include the reactor vessel flange leakoff, valve leakoffs, reactor coolant pump number two seal leakoffs, and the excess letdown heat exchanger flow. No continuous leakage is expected from the reactor vessel flange during operation. The tank is provided with a hydrogen cover gas to minimize dissolved air or nitrogen buildup in the GRWS. This water may be transferred to the Recycle Holdup Tanks and processed with the Boron Recycle System or transferred to the Waste Holdup tank for processing and discharge.HIGH LEVEL CHEMICAL WASTE - High level chemical waste consists of plant samples which have been chemically contaminated. These wastes are collected in the chemical drain tank where pH adjustment is possible. These wastes are normally drained to the floor drain system for processing.LAUNDRY AND PERSONNEL DECONTAMINATION WASTE - Laundry waste is generated by the washing of radioactively contaminated protective clothing and gear for reuse. The personnel decontamination waste contains detergents (inorganics) and/or soaps (organics) used by personnel to remove low level radioactive contamination. The hot showers (Men's shower and Decon shower) in the access control area are used occasionally for personal use and for personnel decontamination when needed.
CALLAWAY - SP11.2-4Rev. OL-2011/13Personnel decontamination wastes are collected in the detergent waste subsystem's detergent drain tank and then transferred to the laundry and hot shower tanks. Laundry waste is collected in the sump located in the Laundry Decontamination Facility and then transferred over to the laundry and hot shower tanks. The waste is then processed and discharged.The various radwaste processing systems are described as follows:LIQUID RADWASTE TREATMENT SYSTEM (LRWTS) - The liquid radwaste treatment system consists of a vendor supplied skid containing a chemical injection system along with a series of demineralizer vessels. The vessels may be operated in any combination or with any treatment media required to process the waste water effectively. Waste water from the CRW and DRW is processed through the components of the LRWTS on an as needed basis to remove the contaminants of concern. Influents to the boron recycle system and RCDT system may be processed with the LRWTS if the recycling of reactor coolant is not desired. Also waste water collected in the laundry and hot shower tanks may be processed through this equipment. The secondary liquid waste monitor tanks normally provide a holdup capacity and the ability to recirculate and sample process stream effluent prior to transferring the processed water to the Discharge Monitor Tanks for discharge.ALTERNATE LIQUID RADWASTE TREATMENT SYSTEM - During situations when the LRWTS is not available, the floor drain tanks and waste holdup tank may be processed by a backup means. The alternate liquid radwaste treatment system consists of a series of filters, demineralizers, charcoal adsorbers and monitor tanks. Waste water from the CRW and DRW system can be processed through these components on an as need basis to remove contaminates of concern. Intermediate monitoring tanks provide a holdup capacity and the ability to recirculate and sample process steam effluent prior to transferring the processed water to the Discharge Monitor Tanks.DISCHARGE MONITOR TANKS - The Discharge Monitor Tanks receive effluents from the LRWTS, Alternate Liquid Radwaste Treatment system, Laundry Waste system and the Secondary Liquid Waste system. The DMT's provide for a final holdup and processing to ensure the effluent quality of the waste water is acceptable for discharge to the environment.Modifications to the Radwaste Systems such as the addition of the LRWS have resulted in the obsolescence of various radwaste equipment and components that are currently installed and pending formal retirement. Operating procedures that govern this equipment have been updated to ensure operation of the obsolete equipment does not occur. Obsolete radwaste equipment/components, along with the equipment identification numbers, system status, and associated FSAR figures, are listed below.a.Recycle evaporator package (SHE02) - pending retirement - FSAR Figure 9.3-11 Sheet 3 CALLAWAY - SP11.2-5Rev.

The LRWS is designed and constructed in accordance with quality group D (augmented). The LRWS is housed within a seismically designed building. Regulatory Guide 1.143 is complied with to the extent specified in Table3.2-5. All tanks which contain or may contain concentrations of radioactivity have provisions to prevent the uncontrolled release of the fluid. Table 11.2-2 indicates the provisions made for each tank.REACTOR COOLANT DRAIN TANK PUMPS - Due to the relative inaccessibility of the containment and the loop drain requirements, two pumps are provided. One pump provides sufficient flow for normal tank operation with one pump for standby. WASTE EVAPORATOR FEED PUMP - One standard pump is used. The waste evaporator feed pump transfers water from the waste holdup tank to the LRWTS or the alternate LRWTS for processing. The pump is shut off when low level is reached in the waste holdup tank. WASTE EVAPORATOR CONDENSATE TANK PUMP - The waste evaporator condensate tank pump is a transfer pump. One standard pump is used to transfer the contents of the waste condensate tank. CHEMICAL DRAIN TANK PUMP - One standard pump can be used to recirculate the liquid in the chemical drain tank.
CALLAWAY - SP11.2-6Rev. OL-2011/13LAUNDRY AND HOT SHOWER TANK PUMP - One standard pump will be used to transfer contents of each L&HST. FLOOR DRAIN TANK PUMPS - Two standard pumps transfer water from the floor drain tanks to the LRWTS or the alternate LRWTS for processing. The pumps are cross-connected to the pump from either floor drain tank.WASTE MONITOR TANK PUMPS - One standard pump is to be used for each tank to transfer water. The pump may also be used for circulating the water in the waste monitor tank in order to obtain uniform tank contents and hence a representative sample before discharge. The pump can be throttled to achieve the desired discharge rate. ACID METERING PUMP - One positive displacement chemical feed pump used to inject sulfuric acid into the discharge monitor tank discharge for pH control.CAUSTIC METERING PUMP - One positive displacement chemical feed pump used to inject sodium hypochlorite into the discharge monitor tank discharge for pH control.REACTOR COOLANT DRAIN TANK HEAT EXCHANGER - The reactor coolant drain tank heat exchanger is a U-tube type with one shell pass and two tube passes. Although the heat exchanger is normally used in conjunction with the reactor coolant drain tank, it can also cool the pressurizer relief tank from 200 to 120°F in less than 8hours. REACTOR COOLANT DRAIN TANK - One tank is provided to collect leakoff type drains inside the containment at a central collection point for further disposition through a single penetration via the reactor coolant drain tank pumps. Only water which can be directed to the recycle holdup tanks enters the reactor coolant drain tank. The tank is provided with a hydrogen cover gas. The water must be compatible with reactor coolant, and it must not contain dissolved air or nitrogen to minimize buildup in the GRWS. Sources of water entering the reactor coolant drain tank include the reactor vessel flange leakoff, valve leakoffs, reactor coolant pump number two seal leakoffs, and the excess letdown heat exchanger flow. No continuous leakage is expected from the reactor vessel flange during operation. WASTE HOLDUP TANK - One atmospheric pressure tank is provided outside the containment to collect equipment drainage, valve and pump seal leakoffs, recycle holdup tank overflows, and other water from tritiated, aerated sources. WASTE EVAPORATOR CONDENSATE TANK - One tank is provided to collect processed waste water from the LRWTS or the Alternate LRWTS.
CALLAWAY - SP11.2-7Rev. OL-2011/13CHEMICAL DRAIN TANK - One tank is provided to collect chemically contaminated tritiated water from the laboratories. LAUNDRY AND HOT SHOWER TANK - Two atmospheric tanks are used to collect laundry and hot shower drainage. FLOOR DRAIN TANKS - Two atmospheric pressure tanks are used to collect floor drainage from the reactor plant operations. WASTE MONITOR TANKS - The two atmospheric waste monitor tanks are provided to aid in processing or storing waste water from the LRWTS or the Alternate LRWTS. DISCHARGE MONITOR TANKS- The two atmospheric discharge monitor tanks are provided for collecting, storing, and monitoring liquid discharges from the plant site.WASTE EVAPORATOR CONDENSATE DEMINERALIZER - One demineralizer is provided to remove ionic contaminants from the waste being processed. LIQUID WASTE CHARCOAL ADSORBER - One charcoal adsorber is provided to remove organics from the waste being processed. The charcoal adsorber also has the capability of being loaded with a specific resin to aid in processing.WASTE MONITOR TANK DEMINERALIZER - One demineralizer is provided to remove trace ionic contaminants from the waste being processed. FILTERS - Most of the filters provided are of a disposable-type cartridge. However, four filters used for processing laundry and hot shower waste are of the disposable bag filter type.The methods employed to change filters and screens are dependent on activity levels. Filters are valved out of service, drained to the appropriate tank, and vented locally. If the radiation level of the filter is low enough, it is changed manually. STRAINERS - Strainers are provided in the discharge of the floor drain tank pumps to remove large particulate matter and thus prevent clogging of the downstream lines and filters. SystemOperation The LRWS operation is manually initiated, except for some functions of the reactor coolant drain subsystem. The system includes adequate control equipment to protect the system components and instrumentation and alarm functions to provide operator information to ensure proper system operation. All pumps in the system have low level shutoffs, and all filters, strainers, and demineralizers have differential pressure indication to indicate fouling.
CALLAWAY - SP11.2-8Rev. OL-2011/13Operation of the LRWS is essentially the same during all phases of normal reactor plant operation; the only differences are in the load on the system. The following sections discuss the operation of the system in performing its various functions. In this discussion, the term "normal operation" should be taken to mean all phases of operation, except operation under emergency or accident conditions. The LRWS is not regarded as a safety-related system. CRW SUBSYSTEM OPERATION - Waste is accumulated in the waste holdup tank until a sufficient quantity exists to process. Normally the waste holdup tank is recirculated and sampled prior to being processed. Chemistry of the tank may be adjusted to ensure optimum system performance. Normally the waste holdup tank is processed utilizing the LRWTS. If the LRWTS is not available, the capability exists to process the waste holdup tank with the alternate liquid radwaste treatment system. If necessary, caustic or acid solution may be added to the waste water by caustic or acid metering pumps to bring the pH into allowable discharge specifications.DRW SUBSYSTEM OPERATION - Normally one floor drain tank is aligned to receive the discharge from the floor drain system while the other tank is being used to supply waste to the processing system. This procedure allows the waste to be sampled and pH adjusted, if desired, prior to processing, to ensure optimum system performance. The second floor drain tank also provides additional system storage capacity during periods of abnormal waste generation or equipment outages. The floor drain tanks are normally processed through the floor drain tank filter to the LRWTS. If the LRWTS is not available, the capability exists to process the floor drain tanks with the alternate liquid radwaste treatment system.REACTOR COOLANT DRAIN TANK SUBSYSTEM OPERATION - Normal operation of the reactor coolant drain subsystem is in the manual mode. Due to the small amount of leakage into the system, less wear and tear on the equipment is experienced by maintaining it in the manual mode. The tank level is monitored by the radwaste operators and pumped out when necessary. The leakage rate of reactor coolant pump No. 2 seal leakoffs, reactor vessel flange leakoffs, valve stem leakoffs and discharges from the excess letdown heat exchanger into the reactor coolant drain tank (RCDT) can be estimated by leaving the system in manual mode and watching the rate of level change. This will measure the identified leakage. The reactor coolant drain tank pumps normally discharge to the boron recycle system. These drains can also be aligned to the waste holdup tank. When in the automatic mode, the level in the RCDT is maintained by running one RCDT pump continuously and using a proportional control valve (LCV-1003) in the discharge line. This valve operates on a signal from the RCDT level controller to limit the flow out of the subsystem. The remainder of the flow is recirculated to the RCDT. The RCDT heat exchanger is sized to maintain the RCDT contents at or below 170°F, assuming an in-leakage of 10 gpm at 600°F.A venting system is provided to prevent wide pressure variations in the RCDT. Normally, the pressure in the RCDT is manually controlled by raising/lowering level in the tank. If too much pressure has built up in the RCDT and cannot be controlled by lowering the CALLAWAY - SP11.2-9Rev. OL-2011/13tank level, manual valves can be opened to the gaseous radwaste system to lower the pressure in the RCDT. The manual valves may also be operated to raise the tank's gaseous overpressure as needed. Hydrogen cover gas is supplied from the service gas system and can be automatically maintained between 2 and 6 psig by pressure-regulating valves. PCV-7155 maintains a minimum tank pressure by admitting hydrogen, while PCV-7152 maintains maximum tank pressure by venting the RCDT to the gaseous radwaste system. The hydrogen is supplied from no more than two 194 SCF bottles, to limit the amount of hydrogen gas which might be accidentally released to the containment atmosphere. The RCDT vents to the gaseous radwaste system to limit any releases of radioactive gases. The reactor coolant drain subsystem may also be used in the pressurizer relief tank (PRT) cooling mode of operation. In this mode, the level control valve in the discharge line to the recycle evaporator feed demineralizers (LCV-1003), the isolation valve at the discharge of the reactor coolant drain tank (HV-7127), and the isolation valve in the reactor coolant drain tank recirculation line (HV-7144) are all closed. The PRT contents are circulated through the reactor coolant drain tank heat exchanger, via valve BB-HV-8031 and the reactor coolant drain tank pumps, prior to returning to the PRT via valve BB-HV-7141. In this mode of operation, the RCDT heat exchanger is capable of cooling the PRT contents from 200°F to 120°F in less than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. As an alternative to returning the cooled fluid to the PRT, the fluid may be directly transferred to the recycle holdup tanks in the boron recycle system. In any and all cases of PRT cooling, the PRT is vented to less than 50 psig to prevent overpressurization of the RCDT subsystem.The reactor coolant drain subsystem may be used to drain the reactor coolant loops by first venting the reactor coolant system, then connecting the spool piece in the RCDT pump suction piping. The design objective of this mode of operation is to drain the RCS to the midpoint of the reactor vessel nozzles in less than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> with both RCDT pumps running. In this mode, valve HV-7144 is closed and, in order to maximize flow capability, the RCDT discharge level control valve (LCV-1003) should be bypassed during RCS draining operations.The reactor coolant drain subsystem may be used to drain down portions of the refueling pool which cannot be drained by the residual heat removal pumps. In this mode of operation, the RCDT heat exchanger may be bypassed and the RCDT level control valve (LCV-1003) may be bypassed to maximize flow through the fuel pool cooling and cleanup system to the refueling water storage tank. An alternate drain line is provided from the refueling pool to the containment sump to route decontamination chemicals away from the RCDT subsystem and minimize the possibility of contaminating any systems downstream of the RCDT pumps.CHEMICAL WASTE - The chemical drain tank (CDT) receives chemically contaminated tritiated water from the plant sample stations. Contents of the tank are sampled, and normally drained to the floor drain system. Operation is intermittent and manually controlled. A high level alarm is provided from the CDT for operator information.
CALLAWAY - SP11.2-10Rev. OL-2011/13LAUNDRY SUBSYSTEM OPERATION - Waste water from the Deep sinks, a washing machine, Men's shower and the personnel decontamination shower are directed by gravity drain to the detergent drain tank located in the basement of the control building and then is pumped to the laundry and hot shower tanks (L&HST's). Laundry waste from the washers and the dryers located in the Laundry Decontamination Facility are collected in the building sump and also pumped over to the L&HST's. The L&HST fluid is low in radioactivity and is normally processed by the L&HST bag filters. The waste may be directed to waste monitor tank "B" and subsequently to the discharge monitor tanks for discharge or directly to the discharge monitor tanks.The laundry system requires makeup water that is normally from a radiologically "clean" source (i.e., Potable water) because water is taken from the system in wet clothes, evaporated in the dryers, and vented from the plant. Potable water will be connected to an OZONE generator, which will provide the bulk of the cleaning agent for the washing machines. Ozone cleans by breaking down the organic molecules in the water and is more effective than chlorine in killing bacteria and reduces or eliminates the need for detergents. Since Ozone requires little or no detergent, there are less residual chemicals in the fabrics after the rinse cycle and fewer rinse cycles are needed. The laundry water is then pumped, on demand of the washing machines, to the laundry equipment in operation. Although the ozone works best in cold water, one washing machine will be equipped with a steam heating system if hot water might be needed. In all phases of laundry operation, the operator must take care to use detergents, soaps, and additives that are compatible with waste processing equipment.DISCHARGE MONITOR TANKS - Normally one discharge monitor tank is aligned to receive plant waste while the other tank is being prepared for discharge. Waste is accumulated until a sufficient quantity exists for processing. The tank is isolated, recirculated, sampled and permitted prior to discharge. The capability exists to reprocess or adjust tank chemistry as necessary to ensure environmental effluent requirements are met. The second discharge monitor tank also provides additional system storage capacity during periods of abnormal waste generation.The LRW system is designed to handle the occurrence of equipment faults of moderate frequency such as:a.Malfunction in the LWRSMalfunction in this system could include such things as pump or valve failures. Because of pump standardization throughout the system, a spare pump can be used to replace most pumps in the system. There is sufficient surge capacity in the system to accommodate waste until the failures can be fixed and normal plant operation resumed.b.Excessive leakage in reactor coolant system equipment CALLAWAY - SP11.2-11Rev. OL-2011/13The system is designed to handle a 1-gpm reactor coolant leak in addition to the expected leakage of 50 lb/day (Ref. 1) during normal operation, which is discussed in Section 5.2.5. Operation of the system is almost the same for normal operation, except that the load on the system is increased. A 1-gpm leak into the reactor coolant drain tank is handled automatically but will increase the load factor of the recycle system. If the gpm leak enters the waste holdup tank, operation is the same as normal, except for the increased load on the system. Abnormal liquid volumes of reactor coolant resulting from excessive reactor coolant or auxiliary building equipment leakage (in excess of 1 gpm) can also be accommodated by the floor drain tank and processed by the LRWTS. Valve and pump leakoffs containing recyclable water are recycled through the waste holdup tank.c.Excessive leakage in the auxiliary system equipmentLeakage of this type could include water from steam side leaks and fan cooler leaks inside the containment which are collected in the containment sump and sent to the floor drain tank. Other sources could be component cooling water leaks, service water leaks, and secondary side leaks. This water will enter the floor drain tank and will be processed and discharged as during normal operation.11.2.3RADIOACTIVE RELEASES This section describes the estimated liquid release from the plant for normal operation and anticipated operational occurrences. 11.2.3.1SourcesSection 11.1 and Appendix 11.1A provide the bases for determining the contained sources inventory and the normal releases. A survey has been performed of liquid discharges from different Westinghouse pressurized water reactor plants. The results are presented in Table 11.2-17 of Reference 2. The data includes radionuclides released on an unidentified basis, and are all within the permissible concentration for the release of liquid containing all unidentified radionuclide mixtures. 11.2.3.2ReleasePoints Refer to Section 11.2.3.2 of the Site Addendum. 11.2.3.3DilutionFactors Refer to Section 11.2.3.3 of the Site Addendum.

SAFETY EVALUATION ONE - Sections 6.2.4 and 6.2.6 provide the safety evaluation for the system containment isolation arrangement and testability. 11.2.5TESTS AND INSPECTION Preoperational testing is discussed in Chapter 14.0
. The operability, performance, and structural and leaktight integrity of all system components are demonstrated by intermittent or continuous operation. 11.2.6INSTRUMENTATION DESIGN The system instrumentation is described in Table 11.2-3 and shown on Figure 11.2-1
. The instrumentation readout is located mainly on the waste processing system panel in the radwaste building. Some instruments are read locally. All alarms are shown separately on the waste processing system panel.The waste processing system pumps are protected against loss of suction pressure by a control setpoint on the level instrumentation for the respective vessels feeding the pumps. The reactor coolant drain tank pumps and the spent resin sluice pump are, in addition, interlocked with flow rate instrumentation and stop operating when the delivery flows reach minimum setpoints. Differential pressure indicators with local readout are provided for filters, strainers, and demineralizers. 11.

OL-2211/1611.3GASEOUSWASTEMANAGEMENTSYSTEMSThe gaseous radwaste system (GRWS) and the plant ventilation exhaust systems control, collect, process, store, and dispose of gaseous radioactive wastes generated as a result of normal operation, including anticipated operational occurrences. This section discusses the design, operating features, and performance of the GRWS and the performance of the ventilation systems. The plant ventilation exhaust systems accommodate other potential release paths for gaseous radioactivity due to miscellaneous leakages, aerated vents from systems containing radioactive fluids, and the removal of noncondensables from the secondary system. Systems which handle these gases are not normally considered gaseous waste systems and are discussed in detail in other sections. These systems are included here to the extent that they represent potential release paths for gaseous radioactivity. 11.3.1DESIGN BASES 11.3.1.1SafetyDesignBasisThe GRWS and other gaseous waste management systems serve no safety-related function. 11.3.1.2PowerGenerationDesignBasesPOWER GENERATION DESIGN BASIS ONE-The GRWS and the ventilation exhaust systems are designed to meet the requirements of the discharge concentration limits of 10CFR20 and the as low as reasonably achievable dose objective of 10CFR50, AppendixI.

The main flow path in the GRWS is a closed loop comprised of two waste gas compressors, two catalytic hydrogen recombiners, six gas decay tanks for normal power service, and two gas decay tanks for service at shutdown and startup. The system also includes a gas decay tank drain collection tank, drain pump, four gas traps to handle normal operating drains from the system, and a waste gas drain filter to permit maintenance and handle normal operating drains from the system. All of the equipment is located in the radwaste building. The closed loop has nitrogen for a carrier gas. The primary influents to the GRWS are combined with hydrogen as the stripping or carrier gas. The hydrogen that is introduced to the system is recombined with oxygen, and the resulting water is removed from the system. As a result, the bulk of all influent gases is removed, leaving trace amounts of inert gases, such as helium and radioactive noble gases to build up. The primary source of the radioactive gas is via the purging of the volume control tank with hydrogen, as described in Section9.3.4. The operation of the GRWS serves to reduce the fission gas concentration in the reactor coolant system which, in turn, reduces the escape of fission gases from the reactor coolant system during maintenance operations or through equipment leakage. Smaller quantities are received, via the vent connections, the reactor coolant drain tank, the pressurizer relief tank, and the recycle holdup tanks. Since hydrogen is removed in the recombiner, this gas does not build up within the system. The largest contributor to the nonradioactive gas accumulation is helium generated by a B10(n,a)Li7 reaction in the reactor core. The second largest contributors are impurities in the bulk hydrogen and oxygen supplies. Stable and long-lived isotopes of fission gases also contribute small quantities to the system gas volume accumulation.Operation of the system is such that fission gases are distributed throughout the six normal operation gas decay tanks. Separation of the GRWS gaseous inventory in several tanks assures that the allowable site boundary dose will not be exceeded in the event of a gas decay tank rupture. Radiological consequences of such a postulated rupture are discussed in Section15.7.1
.
CALLAWAY - SP11.3-3Rev. OL-2211/16The GRWS also provides the capacity for indefinite holdup of gases generated during reactor shutdown. Nitrogen gas from previous shutdowns is contained in one of the shutdown gas decay tanks for use in stripping hydrogen from the reactor coolant system. The second shutdown tank is normally at low pressure and is used to accept relief valve discharges from the normal operation gas decay tanks. For all buildings where there is potential airborne radioactivity, the ventilation systems are designed to control the release. Where applicable, each building has a vent collection system for tanks and other equipment which contains air or aerated liquids. The condenser evacuation system discharge is filtered and discharged to the unit vent in addition to the discharges from the reactor building, auxiliary building, and fuel building. The radwaste building, which houses the GRWS, has its own release vent. The turbine building has an open ventilation system, and the steam packing exhaust discharges into the turbine building. The vent collection systems receive the discharge of vents from tanks and other equipment in the radwaste and auxiliary buildings which contain air or aerated liquids. These components contain only a very small amount of fission product gases. Prior to release via the radwaste or auxiliary building ventilation system, the gases are monitored, as described in Section11.5, and passed through a prefilter, HEPA filter, charcoal filter, and another HEPA filter in series which reduce any airborne particulate radioactivity to negligible levels and provide a decontamination factor of at least 10 for radioactive iodines and 100 for particulates. Expected efficiencies for iodine removal are better than 99percent for elemental iodine and 95percent for organic iodine at 70-percent relative humidity. However, for gaseous effluent release calculations, 70-percent efficiency is conservatively used for radioiodine isotopes. Although plant operating procedures, equipment inspection, and preventive maintenance are performed during plant operations to minimize equipment malfunction, overall radioactive release limits have been established as a basis for controlling plant discharges during operation with the occurrence of a combination of equipment faults of moderate frequency. These faults include operation with fuel defects in combination with steam generator tube leaks and malfunction of liquid or gaseous waste processing systems or excessive leakage in reactor coolant system equipment or auxiliary system equipment. Operational occurrences such as these can result in the discharge of radioactive gases from various plant systems. These unscheduled discharges may be from plant systems which are not normally considered gas processing systems or from a gas decay tank after a 60-day holdup period. If the holdup period restricts plant operation, it may be necessary to decrease this time with prior approval from the Manager, Radiation Protection. These potential sources are tabulated in Table11.1-2
. The bases for assumed releases, the factors which tend to mitigate the release of radioactivity, and the release paths are given in Appendix11.1A
. A further discussion of the gaseous releases from the plant is provided in Section11.3.3

CALLAWAY - SP11.3-4Rev. OL-2211/1611.3.2.2ComponentDescriptionCodes and standards applicable to the GRWS are listed in Tables3.2-1 and 11.3-1. The GRWS is designed and constructed in accordance with quality groupD (augmented). The GRWS is seismically designed, as discussed in Table3.2-5. The GRWS is housed within a seismically designed building. The GRWS design complies with Regulatory Guide1.143, as specified in Table3.2-5
. WASTE GAS COMPRESSOR-The waste gas compressor is a water-sealed centrifugal displacement unit which maintains continuous circulation of nitrogen around the waste gas loop. The compressor is provided with a mechanical shaft seal to minimize water leakage. The compressor moisture separator normal water level is maintained to keep the shaft immersed at all times. Two waste gas compressor packages are provided. One compressor is normally used, and the other compressor is on standby. The packages are self-contained and skid-mounted. Construction is primarily of carbon steel. CATALYTIC HYDROGEN RECOMBINER-The catalytic recombiner disposes of hydrogen brought into the GRWS. This is accomplished by adding a controlled amount of oxygen to the recombiner which reacts with the hydrogen as the gas flows through a catalyst bed. The control system for the recombiner is designed to preclude the possibility of a hydrogen explosion. This is further discussed in Section11.3.6
. Two hydrogen recombiner packages are provided. One recombiner is normally used, and the other is on standby. The packages are self-contained and skid-mounted. The recombiner is located in the system where the hydrogen concentration and pressure are optimum with respect to hydrogen removal. DECAY TANK-Eight gas decay tanks are provided, six for normal power operation and two for service at shutdown and startup. The tanks are of the vertical-cylindrical type and are constructed of carbon steel. MISCELLANEOUS COMPONENTS-The gas decay drain collection tank provides a collection point for condensation drained from the gas decay tanks, recombiners, and gas compressors. All control valves, with the exception of those on the recombiner, are provided with bellow seals to minimize the leakage of radioactive gases through the valve bonnet and stem. Valves on the recombiner package are provided with leakoffs. Relief valves have soft seats and are exposed to pressures which are normally less than two-thirds of the relief valve set pressure. The relief valves of the major components discharge to the shutdown tanks. This permits decay and controlled disposal of all discharges less than about 3,000scf. The relief valves are designed to relieve full flow from both waste gas compressors.
CALLAWAY - SP11.3-5Rev. OL-2211/16To maintain leakage from the system at the lowest practicable level, diaphragm-type manual valves are used throughout the waste gas system. For low temperature, low pressure service valves with a synthetic rubber-type diaphragm are used. This application includes all parts of the system, except the recombiners. Because of the high temperature that may exist in the recombiner, globe type valves with a metal diaphragm seal in the stem are used. There should be no measurable stem leakage from either type of valve. The gas decay tank drain pump directs water from the gas decay drain collection tank (due to condensation or maintenance) to the waste holdup tank or recycle holdup tanks. It is used when there is insufficient pressure in the gas system to drive the fluid. All parts of the pump in contact with the drain water are of austenitic stainless steel. The pump is a canned-motor type. The waste gas drain filter is a disposable cartridge filter provided to prevent particulate matter, including rust, larger than 30microns from entering the LRWS and BRS. All parts of the filter in contact with the drain water are of austenitic stainless steel. The waste gas traps are designed to prevent gases from leaving the GRWS. There are four gas traps-two in the gas decay tank drain line and one each in the recombiner drain lines and compressor drain lines. The component description for the ventilation systems is provided in Section9.4
. 11.3.2.3SystemOperationOperation of the ventilation systems is described in Section9.4. The following is a description of the GRWS. NORMAL OPERATION - The GRWS system is normally operated when increased fission gases or excess hydrogen levels have accumulated in the volume control tank (VCT). When needed, nitrogen gas, with contained fission gases, is circulated around the GRWS loop by one of the two compressors. Fresh hydrogen gas is introduced into the VCT where it is mixed with fission gases stripped from the reactor coolant by the action of the VCT letdown line spray nozzle. The gas is vented from the VCT into the circulating nitrogen in the waste gas system, at the compressor suction.The resulting mixture of nitrogen, hydrogen, and fission gases is pumped by one of the compressors to one of the two catalytic hydrogen recombiners where enough oxygen is added to react with and reduce the hydrogen to a low residual level. Water vapor formed in the recombiner by the hydrogen and oxygen reaction is condensed and removed, and the cooled gas stream (now composed primarily of nitrogen, helium, and fission gases) is discharged from the recombiner, routed through a gas decay tank, and sent back to the compressor suction to complete the loop circuit. Only one gas decay tank is valved into the waste gas loop at any time.
CALLAWAY - SP11.3-6Rev. OL-2211/16If it has been determined that excessive nitrogen buildup is occurring within the system or when other occurrences require it, one tank can be valved out of service and allowed to decay for a period of 60days. If the holdup time restricts plant operation, it may be necessary to decrease this time with prior approval from the Manager, Radiation Protection.STARTUP-At plant startup, the system is first flushed free of air and filled with nitrogen at atmospheric pressure. One compressor, one recombiner, and one shutdown decay tank are in service. The reactor is at the cold shutdown condition. Fresh hydrogen is charged into the volume control tank, and the volume control tank vent gas mixes with the circulating nitrogen in the GRWS. This circulating mixture enters the compressor suction, passes through the recombiner and shutdown gas decay tank, and returns to the compressor suction. When the reactor coolant system hydrogen concentration is within operating specifications, the shutdown gas decay tank is isolated and the gas flow directed to one of the gas decay tanks provided for normal power operation. Gases accumulated in the shutdown tank will be retained for reuse during hydrogen stripping from the reactor coolant system during subsequent shutdown operations. SHUTDOWN AND DEGASSING OF THE REACTOR COOLANT SYSTEM-Plant shutdown operations are essentially startup operations in reverse sequence. During normal power operations a hydrogen purge is maintained on the VCT. After Reactor shutdown, a nitrogen purge to the VCT is begun from the nitrogen header or from a shutdown gas decay tank. A Gas Decay Tank is placed in the process loop so that the gas mixture from the VCT vents to the GRW system and passes through to the recombiner where hydrogen is removed. The volume control tank nitrogen purge is maintained until hydrogen and coolant fission gas concentrations have been reduced to specified levels. During this operation, nitrogen purge flow may be increased to speed up coolant degassing. During degas operations, the inlet Hydrogen analyzer may be bypassed to facilitate Hydrogen removal. Technical Specifications provide the limits to follow during analyzer operations. The nitrogen purge continues until the reactor coolant hydrogen concentration reaches the required level. Degassing is then complete, and the reactor coolant system may be opened for maintenance or refueling. An alternative method to degas the reactor coolant system may also be employed. This method, chemical degassing, reduces the reactor coolant dissolved hydrogen concentration through reaction with hydrogen peroxide. After Reactor shutdown, plant cooldown continues until RCS temperature is less than 180°F. A pre-determined quantity of hydrogen peroxide is added. The hydrogen peroxide reacts with dissolved hydrogen to form water. The reactor coolant is sampled to verify the hydrogen concentration has reached the required level. The VCT nitrogen purge may be performed in conjunction with chemical degas operations if it is desired to reduce reactor coolant system noble gas levels or to help expedite reducing the RCS hydrogen concentration.
CALLAWAY - SP11.3-7Rev. OL-2211/1611.3.3RADIOACTIVE RELEASESThis section describes the estimated gaseous release from the plant for normal operation and anticipated operational occurrences. 11.3.3.1Sources Section 11.1 and Appendix 11.1A provide the bases for determining the contained source inventory and the normal releases. 11.3.3.2ReleasePointsPotential release paths for gaseous radioactivity are illustrated schematically in Appendix11.1A. The general location of potential gaseous radioactivity release points is depicted in Figure1.2-1. A description of potential release points for radioactive gaseous effluents is given in Appendix11.1A, along with the physical characteristics of the gaseous effluent streams. Release points from the gaseous waste processing systems are shown on Figure11.3-2
.11.3.3.3DilutionFactorsThe annual average dilution factors used in evaluating the release of gaseous radioactive effluents for the site are derived and justified in Section 2.3 of the Site Addendum. 11.3.3.4EstimatedDosesTable11.3-2 gives the estimates of offsite doses from radioactive gaseous effluents for the site. Estimated doses were calculated by site consultants and reflect site characteristics, such as distance, grazing factors, and meteorology. The results shown in Table11.3-2 demonstrate that the ALARA criteria of 10CFR50 are met. For a description of assumptions and models for dose calculations, refer to Section11.3 of the Site Addendum. 11.3.4SAFETY EVALUATION The GRWS serves no safety-related function. 11.3.5TESTS AND INSPECTIONSPreoperational testing is described in Chapter14.0
. The operability, performance, and structural and leaktight integrity of all system components are demonstrated by intermittent or continuous operation.
CALLAWAY - SP11.3-8Rev. OL-2211/1611.3.6INSTRUMENTATION APPLICATIONThe GRWS instrumentation, as described in Table11.3-3, is designed to facilitate automatic operation and remote control of the system and to provide continuous indication of system parameters. The instrumentation readout is located mainly on the waste processing system panel in the radwaste building. Some instruments are read where the equipment is located. All alarms are shown separately on the waste processing system panel. Where suitable, instrument lines are provided with diaphragm seals to prevent fission gas outleakage through the instrument. Figure11.3-3 shows the location of the instruments on the compressor package. The compressors are interlocked with the seal water inventory in the moisture separators and trip off on either high or low moisture separator level. During normal operation, the proper seal water inventory is maintained automatically. Figure11.3-4 indicates the location of the instruments on the recombiner installation. The catalytic recombiner system is designed for automatic operation with a minimum of operation attention. Each package includes two online gas analyzers, one to measure hydrogen and oxygen in and one to measure hydrogen and oxygen out, which are the primary means of recombiner control. Each gas concentration channel of these two online gas analyzers is independently controlled. The GRWS is designed to operate with hydrogen concentrations above 4 percent by volume. Flammable mixtures of gases in the system are prevented by monitoring and controlling the oxygen concentration to appropriate levels. The setpoints for oxygen concentration in the catalyst bed inlet stream are 3 percent for the hi alarm and 3.5 percent for the hi-hi alarm and isolation of the oxygen supply. The setpoint for oxygen concentration downstream of the catalyst bed is 60 ppm oxygen for the hi-hi alarm and isolation of inlet oxygen supply. Thus the oxygen supply to the recombiner would be terminated before the concentration in the GRWS would reach levels favorable for hydrogen flammability. Since the GRWS is designed to operate with hydrogen concentrations up to 6 percent by volume, up to 3 percent oxygen is necessary for operation of the catalytic recombiner. Termination of oxygen feed at 2 percent as suggested by regulatory guidance is inappropriate. Further, since the minimum oxygen concentration necessary to support combustion at 4 percent by volume hydrogen concentrations is 5 percent, the hi-alarm setpoint of 3 percent provides sufficient margin (i.e., 60percent of the limit) to flammability. A multipoint temperature recorder monitors temperatures at several locations in the recombiner packages.
CALLAWAY - SP11.3-9Rev. OL-2211/16The process gas flow rate is measured by an orifice located upstream of the recombiner preheater. Local pressure gauges indicate pressure at the recombiner inlet and oxygen supply pressure. The following controls and alarms are incorporated to maintain the gas composition outside the range of flammable and explosive mixtures: a.A high flow alarm sounds at the volume control tank purge flow corresponding to 3percent hydrogen by volume at the inlet to the hydrogen recombiner. b.If the recombiner feed concentration exceeds 4percent by volume, a high-hydrogen alarm sounds. This alarm will be followed by a second alarm indicating high hydrogen in the recombiner discharge. These alarms warn of a possible Section 16.11.2.6 surveillance condition and a possible hydrogen accumulation in the system, respectively.c.If the hydrogen concentration in the recombiner feed reaches 9percent by volume, a high-high hydrogen alarm sounds, the oxygen feed is terminated, and the volume control tank hydrogen purge flow is terminated. These controls limit the possible accumulation of hydrogen in the GRWS to 3percent by volume. d.If the oxygen concentration in the recombiner feed reaches 3percent by volume, an alarm sounds and oxygen feed flow is limited so that no further increase in flow is possible. This control maintains the system oxygen concentration at 3percent or less, which is below the flammable limit for hydrogen-oxygen mixtures. e.If the oxygen concentration in the recombiner feed reaches 3.5 percent by volume, an alarm sounds and the oxygen feed flow is terminated. f.If hydrogen in the recombiner discharge exceeds 1.25percent by volume, an alarm sounds. This alarm warns of high hydrogen feed, possible catalyst failure, or loss of oxygen feed. g.If oxygen in the recombiner discharge exceeds 60ppm, an alarm sounds and oxygen feed is terminated. This control prevents any accumulation of oxygen in the system in case of hydrogen recombiner malfunction. h.On low flow through the recombiner, oxygen feed is terminated. This control prevents an accumulation of oxygen following system malfunction. i.High discharge temperature from the cooler-condenser (downstream from the reactor) will terminate oxygen feed. This protects against loss of cooling water flow in the cooler-condenser.
CALLAWAY - SP11.3-10Rev. OL-2211/16j.High temperature indication by any one of six thermocouples in the catalyst bed will limit oxygen feed so that no further increase is possible. k.High temperature indication at the recombiner reactor discharge will terminate oxygen feed to the recombiner. l.If the oxygen and hydrogen concentrations in the recombiner feed reach 3 and 4 percent respectively by volume, an alarm sounds. This alarm alerts operators to a Section 16.11.2.6 surveillance condition.m.If the oxygen and hydrogen concentration in the recombiner feed both reach 4 percent by volume, an alarm sounds. This alarm alerts operators to a Section 16.11.2.6 recombiner shutdown condition.

The boundary conditions for process parameters include mixing time, waste pH, major chemical substances, liquid waste-to-binder ratio, and solids-to-water ratio. The PCP establishes and defines the administrative controls which will be used and identifies the documentation necessary to ensure that the process is operated within the established boundaries.
SPENT RESINS - The approximate volume that can be solidified in a 55-gallon drum is 3.5 cubic feet of primary spent resins and 4.8 cubic feet of secondary spent resins.SPENT ACTIVATED CHARCOAL - The approximate volume that can be solidified in a 55-gallon drum is 3.5 cubic feet primary spent charcoal and 4.8 cubic feet of secondary spent resins. FILTER CARTRIDGES - Where acceptable per the applicable NRC, DOT, and state regulations, filter cartridges which may be disposed of without stabilization, may be packaged in common drums with up to 12 cartridges per drum or placed within a Low Specific Activity (LSA) box. Filter cartridges requiring stabilization for disposal, will be packaged in individual 55-gallon drums or in approved High Integrity Containers.MISCELLANEOUS DRY WASTES - Miscellaneous paper, clothing, etc., are assumed to have the volume reduced by a factor of five in the compactor, which is a commercially available hydraulic press. 11.4.2.3.2Dry Waste System Low-level dry active wastes are collected at appropriate locations throughout the plant, as dictated by the volume of these wastes generated during operation or maintenance.
Dry wastes, which can be compressed to minimize the shipping volume, may be compacted in 55-gallon drums with a dry waste compactor or may be packaged in approved containers for offsite volume reduction. Compactors are located in the radwaste building, and auxiliary building. The dry waste compactors have an integral shroud which directs any airborne dusts created by the compaction operation through an exhaust fan and filter, and then to the respective building's ventilation system. Packaged containers are sealed and moved either to the drum storage area in the radwaste building, fenced radwaste yards, or to another approved storage location, where they are stored until shipment offsite.
CALLAWAY - SP11.4-6Rev. OL-2211/16Packaged low-level dry active waste may be placed in cargo boxes, such as "Sealands", approved for shipping low-level radioactive waste by the DOT, located in staging areas adjacent to the radwaste building within a RPA.Large components and equipment which have been contaminated or activated during operation are normally handled either by qualified plant personnel or by outside contractors specializing in radioactive materials handling, and are packaged in shipping containers or appropriate shipping packages of an appropriate size. Due to their size, the original steam generators and original reactor vessel closure head are stored in the Old Steam Generator Storage Facility (OSGSF).
11.4.2.3.3Resin Handling System The resin handling system provides the capability for remote removal of spent radioactive resin and activated charcoal from the demineralizer and charcoal adsorber vessels in the chemical and volume control system, fuel pool cooling and cleanup system, boron recycle system, liquid radwaste system, steam generator blowdown system, and secondary liquid waste system and to transfer them to the associated spent resin storage tank or bulk waste disposal station. In the resin transfer mode, the spent resin sluice pumps take suction from the storage tank via a screened connection on the tank and pump water through the respective vessel to first backflush the resin and then sluice the resin to the spent resin storage tank. Primary resin may be also sluiced from the demineralizer vessel to the primary spent resin storage tank with reactor makeup water. Steam generator blowdown resin may be sluiced from the demineralizer vessel to the secondary spent resin storage tank with reactor makeup water. Primary resin or steam generator blowdown resins may also be sluiced directly to the bulk waste disposal station with reactor makeup water. Positive indication that the resin has been sluiced to the spent resin storage tank or bulk waste disposal station is provided by an radiation measuring instrumentation located in the spent resin sluice header or by visually monitoring the bulk waste container.The spent resin storage tank (primary), which accepts spent resins from waste processing systems, is capable of accommodating at least 60 days' waste generation at normal generation rates. The spent resin storage tank (secondary), which accepts spent resin and spent activated charcoal from the remaining vessels, is capable of accommodating at least 30-days' waste generation at normal generation rates. Spent resin and spent activated charcoal are transferred from the spent resin storage tanks to the bulk waste disposal station by pressurizing the storage tank with nitrogen and supplying sluice water at the outlet nozzle on the tank for bulk waste processing. The empty demineralizer or charcoal adsorber vessels are filled with clean media by gravity sluicing from the resin charging tank or by pumping a slurry directly from the new CALLAWAY - SP11.4-7Rev. OL-2211/16media container into the associated vessels. The filling operations are performed remotely from the vessels being filled. 11.4.2.3.4Filter Handling System Filter cartridge changeouts are to be performed utilizing manual changeout techniques.11.4.2.4Bulk Waste Disposal
Bulk waste disposal, as the name implies, involves the processing of large volumes of waste via bulk processing means for subsequent disposal.
The bulk waste disposal station consists of a set of flanged connections installed in a common crossover leg of the solid radwaste system process piping through which spent resin/spent activated charcoal from the spent resins storage tanks may be transferred. Piping or hose connections are made between the bulk waste disposal station waste transfer flange and either a vendor processing skid or directly to an appropriate container such as a liner or a High Integrity Container (HIC). Hoses and/or piping utilized are subjected to pressure tests to verify leak-tight connections and adequacy of the hose or pipe to safely contain and transport the waste.
The addition of cement and additives are recorded and monitored so as to ensure compliance with pre-determined waste solidification formulas.Liners or HIC's provided for bulk dewatering of spent resins/spent activated charcoal incorporate dewatering internals ensure compliance with burial site criteria regarding free water within the disposal container.Dewatering of vendor provided liners or HIC's may be performed by plant operating personnel and equipment, provided the dewatering process and methods to verify dewatering are in compliance with vendor recommendations and applicable regulatory requirements.Upon completion of bulk processing and packaging the liner or HIC is either stored on-site in an approved storage area or shielded storage container or shipped directly offsite for processing by an intermediate processor or for disposal.
CALLAWAY - SP11.4-8Rev. OL-2211/1611.4.2.5Packaging,Storage,andShipment Spent resins, spent charcoal, spent filter cartridges, and solid compactable wastes such as paper, rags, and clothing are packaged in approved containers, in accordance with 49 CFR, and shipped in shielded casks, as required to meet 49CFRdose limitations.
Packaged solid radwaste is normally stored in one of two locations, depending on the requirements for radiation shielding and the amounts of waste temporarily stored onsite. These two locations are designated drummed and bulk solid radwaste storage locations. The storage location for drummed solid radwaste is an annex to the radwaste building, on the south side, as shown in Figure 1.2-3. This storage area includes shielding cubicles for the storage of high level waste such as spent resins and filters. Other containers of radwaste may also be stored in this area. This structure (i.e., the annex to the radwaste building) has concrete walls for radiation shielding. Within this structure are two storage areas, containing 550 and 1,180 square feet of usable floor area. These areas are shielded and remotely maintained to limit radiation exposure to operating personnel. On the basis of stacking the filled drums 5 levels high, the drum capacities of the two areas are 395 and 1,055 drums, pyramidal, or 585 and 1,365 drums, palletized. Packaged solid radwaste in drums, HICs, LSA Boxes, etc., will normally consist of: -Spent resins, primary
-Filter cartridges, primary -Spent resins, secondary -Hazardous/chemical wastes
-Dry wastesIt is estimated that the maximum total of these wastes will be 923 drums per year (refer to Table 11.4-3). Based on this estimate, there is capacity in the radwaste building for approximately 2 years of drummed solid wastes.The storage location for bulk solid radwaste is normally in the outside area adjacent to the drummed storage annex section of the Radwaste Building, on the Plant West side of the building, extending Plant South to the Discharge Monitoring Tank area. This storage area is provided with a concrete slab surface for placement of containers, and is enclosed by a fence with access gates, for control of access to the area. Packaged solid radwaste, in HICs, Boxes or DOT approved shipping containers, is temporarily stored in this or other approved locations onsite while awaiting shipment to an off-site treatment or disposal facility, or for radioactive decay prior to long term storage within a facility structure.
CALLAWAY - SP11.4-9Rev. OL-2211/16While no protection from the environmental elements is afforded to the packaged radwaste containers stored in outside locations, the containers used for packaging these wastes are DOT approved containers for shipment. These containers are designed and manufactured to meet the conditions incident to shipping and disposal. On-site storage containers will be used for interim storage of high integrity containers. Refer to Table 11.4-3 for Estimated Maximum Annual Quantities of Solid Radwaste.11.4.3SAFETY EVALUATION
The containers that require radiation shielding are stored in the radwaste building, which is resistant to tornadoes. These drums will remain in place during any extreme environmental event. The drums or other approved shipping containers for noncompacted, dry wastes, etc., stored outside in bulk storage have low specific activities and, thus, even if dispersed by a tornado do not pose a radiation risk to onsite or off site personnel. The drummed radwaste storage area protects the containers from rainfall and corrosion. As described in Chapter 2.0, flooding is not a potential concern in grade-level buildings at the Callaway site. Although wastes are expected to be stored onsite for some period of time prior to shipment, normally no credit other than 30-day decay will be taken for radioactive decay realized by such storage when filling containers for shipping in accordance with 49 CFR dose limitations. That is, once filled, containers can normally be shipped immediately, subject to availability of a disposal site, with the proper shielding, without exceeding Department of Transportation radiation limits. If 49 CFR dose limitations cannot be met with the available shielding, however, the applicable containers are stored in appropriate storage areas until the doses are acceptable for shipping in accordance with Department of Transportation requirements. The minimum onsite residence time for low level solid radwaste prior to shipping, such as dry compacted waste, steam generator blowdown spent resins, and spent charcoal, ranges from several days to a few months. The minimum onsite residence time for solid radwaste prior to shipping, such as primary spent resins and spent filter cartridges from the primary system, ranges from a few months to a few years. Onsite residence time is based on the initial activity of the container, the time required to have sufficient containers to completely load a transporting vehicle, the thickness of the shields available, the number of containers which can be stored in the available shipping casks, the availability of a transporting vehicle, and the availability of ultimate disposal facilities. All solid radwaste is shipped from the site in Department of Transportation-approved containers by Department of Transportation-approved carriers. Containers with any CALLAWAY - SP11.4-10Rev. OL-2211/16significant surface dose rate are moved remotely from the shielded storage areas to the transporting vehicle.Radiation measurements made at the time of shipment of any radioactive waste material ensure that all shipments leave the site well within prescribed limits. Similarly, external contamination measurements are made to detect any potential release of radioactive material from the container prior to shipment.11.4.4TESTS AND INSPECTIONS The SRS is in intermittent use throughout normal reactor operation. Periodic visual inspection and preventative maintenance are conducted using normal industry practice. Refer to Chapter 14.0 for further information. 11.4.5INSTRUMENTATION APPLICATION Two control panels are provided for the equipment in the SRS which contains or processes potentially radioactive fluids or slurries. One control panel is located in the radwaste building control room and contains the instrumentation for the equipment which interfaces the influent systems (i.e., spent resin storage tank - primary, and spent resin storage tank - secondary) and for the equipment used for process control (i.e., caustic addition tank, and caustic addition metering pump). The second control panel (solidification control panel) is located in a separate room in close proximity to the solidification processing area. The control panel contains all instrumentation, including television monitors, required for transferring waste to the bulk waste disposal station. Pertinent instruments and controls for the transferring of the wastes from the tanks containing the wastes are duplicated on this panel so that the solid radwaste solidification system operator can transfer the waste from these tanks to the bulk waste disposal station.

Dry waste compactors are designed with ventilation shroud exhaust fan and filter to control the airborne dust during the compaction process.b.Activated charcoal, HEPA filters, and other dry wastes which do not normally require solidification processing should be treated as radioactively contaminated solids and packaged for disposal in accordance with applicable Federal regulations.I.1.bComplies.2.Wet Wastesa.Wet wastes such as spent bead and powdered resins and filter sludge should be rendered immobile by combining with a suitable binding agency (cement, urea formaldehyde, asphalt, etc.) to form a homogenous solid matrix (absent of free water) prior to offsite shipment. Absorbents such as vermiculite are not acceptable substitutes for binding agents.I.2.aComplies. Packaging of radioactive filter sludge complies in that these wastes will be combined with a suitable binding agent (e.g., cement) to form a homogeneous solid matrix prior to offsite shipment. Packaging of radioactive spent demineralizer resins also complies (resins may be combined with a suitable binding agent to create a homogeneous solid matrix prior to offsite shipment) except that they may be packaged by dewatering in a steel liner or High Integrity Container per the requirements of 10CFR61, prior to offsite shipment. Absorbent will not be used as a substitute for a binding agent for wastes requiring immobilization. Waste not requiring immobilization will be packaged using acceptable methods approved by DOT and burial site requirements.b.Spent cartridge filter elements may be packaged in a shielded container with a suitable absorber such as vermiculite, although it would be desirable to solidify the elements in a suitable binder.I.2.bComplies.II.ASSURANCE OF COMPLETE SOLIDIFICATIONComplete solidification of wet wastes should be assured by the implementation of a process control program or by methods to detect free liquids within container contents prior to shipment.1.Process Control Program CALLAWAY - SPTABLE 11.4-1 (Sheet 2)Rev.

OL-195/1211.5PROCESS AND EFFLUENT RADIOLOGICAL MONITORING AND SAMPLINGSYSTEMSThe function of the process and effluent radiological monitoring systems is to monitor, record, and control the release of radioactive materials that may be generated during normal operation, anticipated operational occurrences, and postulated accidents. The process and effluent radioactivity monitoring systems furnish information to operations personnel concerning radioactivity levels in principal plant process streams and atmospheres. The monitoring systems indicate and alarm excessive radioactivity levels (GDC-63). They initiate operation of standby systems, provide inputs to the ventilation and liquid discharge isolation systems, and record the rate of release of radioactive materials to the environs, as outlined in Regulatory Guide 1.21 and GDCs 60 and 64. The systems consist of permanently installed, continuous-monitoring devices together with a program and provisions for specific sample collections and laboratory analyses. 11.5.1DESIGN BASES The principal objectives and criteria of the process and effluent radiological monitoring systems are provided below. 11.5.1.1SafetyDesignBasesSAFETY DESIGN BASES - The control room ventilation monitors, the containment purge monitors, and the fuel building exhaust monitors are designed to activate engineered safety features systems in the event that airborne radioactivity in excess of allowable limits exists. Additional design bases are stated in the following sections:a.Containment purge isolation system, Sections 6.2.4
, 7.3.2, 9.4.6, and 12.3.4. b.Fuel building ventilation isolation, Sections 7.3.3
, 9.4.2, and 12.3.4. c.Control room intake isolation, Sections 6.4.1
, 7.3.4, 9.4.1, and 12.3.4. These radioactivity monitors are protection system elements and are designed in accordance with IEEE Standard279. The safety evaluation of these systems is discussed in Section7.3

.
CALLAWAY - SP11.5-2Rev. OL-195/1211.5.1.2PowerGenerationDesignBasesPOWER GENERATION DESIGN BASIS ONE - The process and effluent radioactivity monitors operate continuously during both intermittent and continuous discharges of potentially radioactive plant effluents, in compliance with Regulatory Guide 1.21. The monitors verify that the most restrictive anticipated nuclides are at concentrations within the limits specified in Table II of Appendix B of 10 CFR 20 and that the concentrations are low enough that 10 CFR 50 Appendix I dose guidelines are met for unrestricted areas. POWER GENERATION DESIGN BASIS TWO - The process and effluent radioactivity monitors alarm and automatically terminate the release of effluents when radionuclide concentrations exceed the limits specified (GDC-60). Where termination of releases is not feasible, the monitors provide continuous indication of the magnitude of the activity released. POWER GENERATION DESIGN BASIS THREE - The radwaste process system monitors measure radioactivity in process streams to aid personnel in the treatment of radioactive fluids prior to recycle or discharge (GDC-63). POWER GENERATION DESIGN BASIS FOUR - The process and effluent radioactivity monitors monitor the containment atmosphere, spaces containing components for recirculation of LOCA fluids, effluent discharge paths, and for radioactivity that may be released from postulated accidents, as required by GDC-64. POWER GENERATION DESIGN BASIS FIVE - The process and effluent monitors indicate the existence and, to the extent possible, the magnitude of reactor coolant and reactor auxiliary system leakage to the containment atmosphere, cooling water systems, or the secondary side of the steam generators. POWER GENERATION DESIGN BASIS SIX - The process and effluent radioactivity monitors provide alarm and automatic termination of the transfer of radioactivity fluids to storage facilities in zone A areas, defined in Section 12.4.1.1
. POWER GENERATION DESIGN BASIS SEVEN - Process radioactivity monitors provide alarm and gross indication of the extent of any failed fuel within the primary system. POWER GENERATION DESIGN BASIS EIGHT - The effluent radioactivity monitors provide sufficient radioactivity release data to prepare the reports required by Regulatory Guide1.21.
CALLAWAY - SP11.5-3Rev. OL-195/1211.5.1.3CodesandStandards Codes and standards applicable to the process and effluent radioactivity monitors are indicated in Table 3.2-1. The monitors listed in Section 11.5.1.1 are designed as protection system elements. 11.5.2SYSTEM DESCRIPTION11.5.2.1GeneralDescription11.5.2.1.1Data CollectionThe process and effluent radiological monitoring systems consist of liquid and airborne radioactivity monitors with the attendant controls, alarms, pumps, valves, and indicators required to meet the design bases. Each monitor consists of the detector assembly and a local microprocessor. The local microprocessor processes the detector assembly signal in digital form, computes average radioactivity levels, stores data, performs alarm or control functions, and transmits the digital signal to the control room microprocessor.
Signal transmission is accomplished via redundant data highways. A single fault in either data highway will not prevent the control room microprocessor from receiving the data. The Laundry Decon Facility Dryer Exhaust Monitor is a self contained unit and provides alarms and control function locally.The local microprocessors for monitors which perform safety functions (control room ventilation, fuel building ventilation, containment atmosphere, and containment purge monitors, refer to Section 12.3.4) are wired directly to individual indicators located on the seismic Category I radioactivity monitoring system cabinets in the control room. The input from the safety-related channels to the daisy-chain loop is an isolated signal to ensure that the safety-related signals will not be affected by signals or conditions existing in the nonsafety portion of the system. The control room microprocessor provides controls and indication for the radioactivity monitoring system. Indication is via a Visual Display located in the control room. The signals from each monitor may also be recorded on a system printer.11.5.2.1.2Alarms Each monitor channel is provided with a three-level alarm system. One alarm setpoint is below the background counting rate and serves as a circuit failure alarm. The other two-alarm setpoints provide sequential alarms on increasing radioactivity levels. Loss of power will cause an alarm on all three-alarm circuits. The alarms must be manually reset and can be reset only after the alarm condition is corrected. The Laundry Decon Facility Dryer Effluent Monitor will alarm and isolate the effluent path when measured levels are above the alarm setpoint or the monitor fails.
CALLAWAY - SP11.5-4Rev. OL-195/1211.5.2.1.3Check SourcesEach monitor is provided with a check source, operated from the control room, which simulates a radioactive sample in the detector assembly for operational and gross calibration checks. The Laundry Decon Facility Dryer Effluent Monitor is source checked manually.11.5.2.1.4Power SuppliesAll Class 1E radioactivity monitoring systems are powered from Class 1E motor control centers. The power supplies for all of the monitors are given in Table11.5-5
. 11.5.2.1.5Calibration and MaintenanceThe radioactivity monitors are calibrated by the manufacturer for at least the principal radionuclides listed in Tables 11.5-1 through 11.5-4. The manufacturer's calibration standards are traceable to National Bureau of Standards primary calibration standard sources and are accurate to at least 5 percent. The source detector geometry during this primary calibration is identical to the sample detector geometry. Secondary standards counted in reproducible geometry during the primary calibration are supplied with each continuous monitor. The secondary standards are accurate to at least 10 percent. The Laundry Decon Facility Dryer Exhaust Monitor is calibrated on site using plant procedures.Channel checks and source checks are performed at regular intervals to ensure proper monitor function. The monitors are re-calibrated at regular intervals, and following repairs or modifications, using the secondary radionuclide standard.Any effluent released to the environment is analyzed for radioactivity prior to release. If, at any time, an effluent monitor requires maintenance or decontamination, the effluent stream will be terminated or periodic grab sampling with laboratory analysis will be implemented in accordance with Offsite Dose Calculation Manual requirements. This does not impair system integrity since the detector is off-line and not installed in the stream. 11.5.2.1.6Sensitivities Each effluent monitoring system will be able to detect a minimum concentration within the release limits established in the Offsite Dose Calculation Manual. Due to sensitivity considerations, monitors are located at the effluent release points. Dilution factors between the release point and the site boundary are considered in complying with the limitations of 10 CFR 50, AppendixI. Tables 11.5-1 through 11.5-4 provide the detailed sensitivity requirements for the process and effluent monitors.
CALLAWAY - SP11.5-5Rev. OL-195/1211.5.2.1.7Monitor LocationsThe monitors are located in low background areas, near the systems being monitored, to minimize background and sampling interferences. 11.5.2.1.8Ranges and Setpoints The ranges of the various process monitors are based on the expected activity levels in the system being monitored. The bases for their setpoints are determined by the need for process control and to alert the operators of leakage of radioactivity into normally nonradioactive systems. The ranges of the various effluent monitors are based on the ability to detect radioactivity concentrations at the effluent release point which might result in site boundary doses in excess of 10 CFR 50 Appendix I levels to those from postulated accidents. The Alert alarm is administratively established at a point sufficiently below the High alarm so as to provide additional assurance that Offsite Dose Calculation Manual limits are not exceeded. The High alarm is established to ensure that Offsite Dose Calculation Manual limits are not exceeded. The ranges and setpoints for the process and effluent monitors are provided in Tables 11.5-1 through 11.5-4. 11.5.2.1.9Expected System Parameters The expected ranges of system parameters, such as flow, composition, and concentrations, are summarized in Tables 11.5-1 through 11.5-4. Detailed information on the individual systems can be found in other sections of the FSAR, principally Chapters9.0 and 11.0. 11.5.2.2LiquidMonitoringSystems11.5.2.2.1Selection Criteria for Liquid MonitorsThe liquid monitors consist of fixed-volume, off-line, lead-shielded sample chambers through which the liquid samples flow. A NaI(Tl) gamma scintillation detector is located within each sample chamber to detect the activity level. Except for the Chemical and Volume Control (CVCS) Letdown Monitor, the detector assemblies monitor gross gamma activity in the range of 10
-7 to 10-2 µCi/ml. The CVCS letdown monitor detector assembly monitors failed fuel product activity in the range of 1.7 x 10
-3 to 1.7 x 10
+3 µCi/ml. The controlling isotope for the liquid monitors is Cs-137. Minimum detectable concentrations are listed in Tables 11.5-1 and 11.5-2.
CALLAWAY - SP11.5-6Rev. OL-195/12A motor operated valve at the sample chamber inlet is provided to isolate sample flow to permit purging of the sample chamber to facilitate background activity checks. A source of noncontaminated water is provided for decontamination purposes. Sample chambers in which permanent contamination interferes with measurement can readily be replaced. Liquid monitor alarms are annunciated in the control room on the plant annunciator and the radiation monitoring system Visual Dislay and printer. The radiation monitoring system Visual Display provides a visual alarm display in the control room. The liquid radioactivity monitors are located to comply with the design bases. The specific sample points are selected to provide representative samples of the systems monitored, to reduce sample transport times, and to limit the amount of radioactivity released in the event of a high radioactivity signal. The continuous liquid radioactivity monitoring systems are discussed in the following sections. A summary of the functions and characteristics of each monitor is presented in Tables 11.5-1 and 11.5-2. 11.5.2.2.2Liquid Process Radioactivity MonitorsA detailed listing of liquid process monitor parameters is given in Table11.5-1
. 11.5.2.2.2.1Component Cooling Water MonitorsThe component cooling water system (CCWS) is discussed in Section9.2.2
. The CCW radioactivity monitors, 0-EG-RE-9 and 0-EG-RE-10, detect, indicate, and alarm any inleakage to the CCWS from potentially radioactive systems and components served by the CCWS. Each detector assembly receives a continuous sample flow from the CCW heat exchanger inlet in the associated loop and returns the sample to the component cooling pump section header. This sample point is downstream of all potential radioactive inleakage. The component cooling pumps provide the motive force for the sample. The alert alarm provides indication of inleakage to the system. A high alarm is provided to indicate increasing radioactivity levels and to close the component cooling water surge tank air vent valves. 11.5.2.2.2.2Steam Generator Liquid Radioactivity Monitor The steam generator liquid sample system is discussed in Section9.3.2
. The steam generator liquid radioactivity monitor, 0-SJ-RE-2, monitors the blowdown from the steam generators, either individually or collectively, to detect, indicate, and alarm primary-to-secondary system leaks in the steam generators.
CALLAWAY - SP11.5-7Rev. OL-195/12The monitor also provides backup information and verification of the condenser air removal system gaseous radioactivity monitor (Section 11.5.2.3.2.1). The fixed-volume detector assembly receives a continuous flow from the steam generator liquid sample header which samples the tube sheet area near the minimum water level of the steam generators. The sample point is located downstream of the sample system heat exchanger to provide conditioning and pressure reduction of the radioactivity monitor sample. The radioactivity alarms provide indication of primary-to-secondary leakage in the steam generator. 11.5.2.2.2.3Steam Generator Blowdown Processing System Radioactivity MonitorThe steam generator blowdown processing system is discussed in Section10.4.8
. The steam generator blowdown processing radioactivity monitor, 0-BM-RE-25, continuously monitors the fluid entering the steam generator blowdown filters to detect, alarm, and indicate excessive radioactivity levels in the blowdown system. The monitor provides backup information for the steam generator liquid radioactivity monitor (Section 11.5.2.2.2.2) and the condenser air removal gaseous radioactivity monitor (Section 11.5.2.3.2.1) for the detection of a primary-to-secondary leakage in the steam generator. The fixed-volume detector assembly receives a continuous flow from the discharge of the blowdown system heat exchangers and returns the sample to the system. The sample location provides an unfiltered sample at temperatures within the limits of the detector. The high radioactivity alarm closes the blowdown system discharge valve to prevent discharge of radioactivity from the steam generators. 11.5.2.2.2.4Essential Service Water/Service Water System Radioactivity MonitorNo radioactivity monitors are required in the Service Water/Essential Service Water (SW/ESW) System. Monitors are not required because components served by SW/ESW are normally non-radioactive. To detect inleakage into the SW/ESW system, periodic samples of the SW/ESW system will be analyzed. Analysis of SW/ESW for activity will be performed weekly when the Component Cooling Water and the Steam Generator Blowdown activity is less than the alarm setpoint of 0-EG-RE-09, 0-EG-RE-10, 0-SJ-RE-02 and 0-BM-RE-25. This sampling will be performed more frequently if radiation monitors 0-EG-RE-09, 0-EG-RE-10, 0-SJ-RE-02 or 0-BM-RE-25 reach the alarm setpoint.11.5.2.2.2.5Deleted11.5.2.2.2.6Chemical and Volume Control Letdown MonitorThe chemical and volume control system (CVCS) is discussed in Section9.3.4
. The CVCS letdown radioactivity monitor, 0-SJ-RE-01, acts as a gross failed fuel detector. The fixed-volume detector assembly continuously monitors the CVCS letdown sample line which extracts a sample upstream of the CVCS letdown demineralizers. The CALLAWAY - SP11.5-8Rev. OL-195/12radiation alarms alert the operator to an abnormal increase in gamma activity in the CVCS letdown system. Determination of the cause can be made by laboratory analysis. The sample location provides an unfiltered sample prior to demineralization. The arrangement and location of the sample line provide sufficient delay in transport to allow decay of nitrogen-16, which could cause erroneously high readings. 11.5.2.2.2.7Auxiliary Steam System Condensate Recovery MonitorThe auxiliary steam system is discussed in Section9.5.9
. The auxiliary steam condensate recovery radioactivity monitor, 0-FB-RE-50, detects radioactive contamination from the potentially radioactive systems which discharge to the auxiliary steam condensate recovery tank. The fixed-volume detector assembly continuously monitors the discharge of the auxiliary steam condensate transfer pumps. The radioactivity alarms alert the operator to possible contamination. The source of the contamination can be determined by selective isolation of the potentially radioactive systems. The sample location ensures that all potentially radioactive sources are monitored. 11.5.2.2.3Liquid Effluent Radioactivity MonitorsA detailed listing of the liquid effluent monitor parameters is given in Table 11.5-2
. 11.5.2.2.3.1Steam Generator Blowdown Discharge Radioactivity Monitor The steam generator blowdown system is discussed in Section10.4.8
. The steam generator blowdown discharge radioactivity monitor, 0-BM-RE-52, continuously monitors the blowdown discharge pump outlet to detect radioactivity due to system demineralizer breakthrough and to provide backup to the steam generator blowdown process radioactivity monitor (Section 11.5.2.2.2.3) to prevent discharge of radioactive fluid. The sample point is located on the discharge of the pump in order to monitor discharge or recycled blowdown fluid and upstream of the discharge isolation valve to limit the radioactivity released. The high radioactivity alarm acts to close the blowdown isolation valves and the blowdown discharge valve. Laboratory isotopic analyses will be performed in accordance with the Offsite Dose Calculation Manual. 11.5.2.2.3.2Liquid Radwaste Discharge Monitor The liquid radwaste system is discussed in Section11.2
.
CALLAWAY - SP11.5-9Rev. OL-195/12The liquid radwaste radiation monitor, 0-HB-RE-18, continuously monitors the discharge of the liquid radwaste, steam generator blowdown, secondary liquid waste, and liquid waste discharged from the radwaste discharge monitor tanks to prevent the discharge of radioactive fluid to the environs. The fixed-volume detector assembly continuously monitors the system discharge line upstream of the discharge valve. The high radioactivity alarm closes the liquid radwaste system discharge valve to terminate discharge. The sample point is located to ensure that all potentially radioactive fluids from the liquid radwaste processing system are monitored prior to discharge. Laboratory isotopic analyses will be performed on each batch, prior to discharge, in accordance with the Offsite Dose Calculation Manual. 11.5.2.2.3.3Deleted 11.5.2.2.3.4Deleted 11.5.2.3AirborneMonitoringSystems11.5.2.3.1Selection Criteria for Airborne Monitors11.5.2.3.1.1IntroductionThe type of fixed instrumentation used for monitoring airborne radioactivity is offline. The offline system extracts a sample from the process stream and transports that sample to the radioactivity monitoring system, which contains the specified equipment to detect particulates, halogens, and/or noble gases. 11.5.2.3.1.2Sampling Criteria The sampling system for the particulate/halogen/noble gas monitors is designed and installed to meet the intent of ANSI N13.1-1969 guide to sampling of airborne radioactive materials. Systems whose sensitivity is dependent upon sample flow employ isokinetic nozzles and suitable control of flow rate. 11.5.2.3.1.3Detection CriteriaSince both radioactive particulates and radioactive noble gases are beta emitters, beta sensitive scintillation detectors are used to sense radioactivity in order to minimize the effects due to background radiation and, consequently, obtain a lower minimum detectable concentration. The Laundry Decon Facility Dryer Exhaust Monitor uses a Geiger-Mueller counter.Where spectrometric analysis is required (such as in iodine monitoring) an NaI(Tl), gamma scintillation detector assembly is employed.
CALLAWAY - SP11.5-10Rev. OL-195/1211.5.2.3.1.4Instrumentation CriteriaInstrumentation necessary to indicate, alarm, and perform control functions will be provided to complete the monitoring system. Since radioactive concentrations may vary substantially, wide range instruments are utilized. The particulate and charcoal filters can readily be removed for periodic isotopes laboratory analyses, as required by the Offsite Dose Calculation Manual. The airborne particulate monitors each consist of a fixed filter upon which radioactive particulate matter is deposited. The fixed filter is located in front of a beta scintillation detector coupled to a photomultiplier tube. The fixed filter for the Laundry Decon Facility Dryer Exhaust Monitor is located in front of a Geiger-Mueller counter.Each airborne iodine monitor consists of a charcoal cartridge upon which iodine is adsorbed. The air sample is prefiltered to remove particulates. The charcoal cartridge is located in front of a gamma scintillation detector coupled to a photomultiplier tube. Each airborne noble gas monitor consists of a fixed-volume sample chamber through which prefiltered sample air is passed. A beta scintillation detector is located within the sample chamber to detect the activity level of the air sample. All of the detectors and sample chambers are enclosed in heavily shielded lead pigs. Two motor-operated valves operated locally are provided to permit air-purging of the sample chamber to facilitate background activity checks. The Laundry Decon Facility Dryer Exhaust Monitor detector is shielded from background. Isolation and purge valves are not installed.The sensitivities and alarm setpoints are given in Tables 11.5-3 and 11.5-4. The alert-alarm points are based on the most restrictive isotopes which are expected to be present. 11.5.2.3.2Airborne Process Radioactivity Monitors A detailed listing of airborne process monitor parameters is given in Table 11.5-3
. 11.5.2.3.2.1Condenser Air Discharge MonitorThe condenser air discharge monitor, 0-GE-RE-92, is provided to detect, indicate, and alarm gaseous activity in the condenser air removal system exhaust. This monitor provides backup to the steam generator liquid and the steam generator blowdown processing radiation monitors for detection of primary-to-secondary leaks in the steam generator. The condenser air removal system removes noncondensable gases which would be present if a primary-to-secondary leakage occurred.
CALLAWAY - SP11.5-11Rev. OL-195/12The monitor extracts a representative sample of air and noncondensable gases from the exhaust duct. A sample cooler is provided to dry the sample prior to entering the fixed-volume gaseous detector assembly to preclude damage to the detector. The sample point is located upstream of the condenser air removal system filters. The radiation alarms alert the operator to the presence of gaseous activity and the possibility of steam generator tube leakage. 11.5.2.3.2.2Containment Atmosphere Radioactivity Monitors The containment atmosphere radioactivity monitors, 0-GT-RE-31 and 0-GT-RE-32, continuously monitor the containment atmosphere for particulate, iodine, and gaseous radioactivity. These monitors also serve for reactor coolant pressure boundary leakage detection (See Section 5.2.5 for a detailed description of this function) and for personnel protection (see Section 12.3.4 for a detailed description of this function). The containment atmosphere radioactivity monitors provide backup indication for the containment purge monitors. These seismic CategoryI monitors are completely redundant. Samples are extracted from the operating deck level (El. 2047'-6") through sample lines which penetrate the containment. The monitors are located as close as possible to the containment penetrations to minimize the length of the sample tubing and the effects of sample plate out. The sample points are located in areas which ensure that representative samples are obtained. Each sample passes through the penetration, then through the fixed filter (particulate), charcoal filter (iodine), and fixed-volume gaseous detector assemblies. After passing through the pumping system, the sample is discharged back to the containment through a separate penetration. Indication is provided for each monitor on individual indicators on the radioactivity monitoring system control panel and, through isolated signals, on the radioactivity monitoring system Visual Display in the control room. 11.5.2.3.2.3Containment Purge System Radioactivity MonitorsThe containment purge system radioactivity monitors, 0-GT-RE-22 and 0-GT-RE-33, continuously monitor the containment purge exhaust duct during purge operations for particulate, iodine, and gaseous radioactivity. The purpose of these monitors is to isolate the containment purge system on high gaseous activity via the ESFAS. See Sections 7.3.2 and 9.4.6 for additional information concerning this function. These monitors also serve as backup indication for personnel protection (see Section 12.3.4) and reactor coolant pressure boundary leakage detection (see Section 5.2.5) for the containment atmosphere radioactivity monitors. These seismic Category I monitors are completely redundant.
CALLAWAY - SP11.5-12Rev. OL-195/12The sample points are located outside the containment between the containment isolation dampers and the containment purge filter adsorber unit. Each monitor is provided with two isokinetic nozzles to ensure that representative samples are obtained for both normal purge and minipurge flow rates. Isokinetic nozzle selection is accomplished by sample selector valves which automatically align the correct nozzle to the monitor based on operation of the minipurge and normal purge exhaust systems. The sample is extracted through the selected nozzle and then passed through the selector valve, the fixed filter (particulate), charcoal filter (iodine), and fixed-volume gaseous detectors. The sample then passes through the pumping system and is discharged back to the duct.Indication is provided for each monitor on individual indicators on the radioactivity monitoring system control panel and, through isolated signals, on the radioactivity monitoring system Visual Display in the control room. For plant conditions during CORE ALTERATIONS and during movement of irradiated fuel within containment, the function of the monitors is to alarm only and the trip signals for automatic actuation of CPIS may be bypassed. One instrumentation channel at a minimum is required for the alarm only function during plant refueling activities.11.5.2.3.2.4Containment High Range Radiation MonitorsThe containment digital high range radiation monitor (DHRRM) system includes two redundant monitors, 0-GT-RT-59 and 0-GT-RT-60, to detect and indicate gamma radiation levels in the containment over a range from 1 rad/hr to 10 8 rads/hr. The DHRRM also provides an alarm function.Each DHRRM subsystem consists of a gamma radiation detector, a microprocessor, junction box, and control/display module. The subsystems are safety related and designed and qualified to IEEE 323-1974 for the normal and accident environments for their installed locations. The subsystems are also designed and qualified to be seismic CategoryI. The detector locations are indicated on Figure 12.3-2, Sheet 4. Detectors are mounted on the inside surface of the containment wall at El. 2052'-0". The DHRRM subsystems are also connected to the process and effluent radiation monitoring system (optically isolated) for readout on the Visual Display in the control room. 11.5.2.3.2.5Fuel Building Ventilation Exhaust Radioactivity Monitor The fuel building ventilation exhaust radiation monitors, 0-GG-RE-27 and 0-GG-RE-28, continuously monitor for particulate, iodine, and gaseous radioactivity in the fuel building ventilation exhaust system. In the event of a fuel handling accident, these monitors function to isolate the normal ventilation and start up the emergency ventilation system on high gaseous activity via the ESFAS. Sections 7.3.3 and 9.4.2 have additional information about this function. These monitors have an additional function to alert CALLAWAY - SP11.5-13Rev. OL-195/12workers to high airborne radioactivity in the fuel building. This latter function is discussed in Section12.3.4
. These seismic Category I monitors are completely redundant. During normal operation, each monitor extracts a sample from the normal exhaust duct through individual isokinetic nozzles and sample selector valves. This normal sample point is upstream of the fuel building normal exhaust filter adsorber unit. When the emergency ventilation system is in use, the capability is provided from the control room to transfer the sample points via sample selector valves to isokinetic nozzles located in the fuel building emergency exhaust system upstream of the emergency exhaust filter adsorber units, with one monitor aligned to each emergency exhaust duct. Indication is provided by individual indicators on the radioactivity monitoring system control panel and, through isolated signals, by the radioactivity monitoring system Visual Display in the control room. 11.5.2.3.2.6Control Room Ventilation Radioactivity MonitorThe control room ventilation radioactivity monitors, 0-GK-RE-04 and 0-GK-RE-05, continuously monitor the supply air of the normal heating, ventilation, and air-conditioning system for particulate, iodine, and gaseous radioactivity to provide protection for the control room operators. These monitors function automatically to switch the control room from the normal to the emergency ventilation system on high gaseous activity via the ESFAS. See Sections 6.4
, 7.3.4, and 9.4.1 for more details. These monitors also function to alert the operators to high airborne radioactivity in the control room ventilation supply. This function is described in Section 12.3.4
. These seismic CategoryI monitors are completely redundant. Samples are extracted through individual isokinetic nozzles, and flow through the fixed filter (particulate), charcoal filter (iodine), and fixed-volume gaseous detector assemblies prior to passing through the pumping system for discharge to the auxiliary building atmosphere. Indication for these monitors is provided on individual indicators on the radioactivity monitoring system control panel and, through isolated signals, on the radioactivity monitoring system Visual Display in the control room. 11.5.2.3.3Airborne Effluent Radioactivity Monitors A detailed listing of airborne effluent monitor parameters is given in Table 11.5-4
.
CALLAWAY - SP11.5-14Rev. OL-195/1211.5.2.3.3.1Unit Vent Radioactivity MonitorThe unit vent radioactivity monitor, 0-GT-RE-21, continuously monitors the effluent from the unit vent for particulate, iodine (halogen), and gaseous radioactivity. The unit vent, via ventilation exhaust systems, continuously purges various tanks and sumps normally containing low-level radioactive aerated liquids that can potentially generate airborne activity. The exhaust systems which supply air to the unit vent are from the fuel building, auxiliary building, the access control area, the containment purge, and the condenser air discharge. All of these systems are filtered before they exhaust to the unit vent. The unit vent monitor measures actual plant effluents and not inplant concentrations. Thus, the system continuously monitors downstream of the last point of potential radioactivity entry. The monitoring system consists of an off-line, three-way airborne radioactivity monitor. An isokinetic sampling probe is located downstream of the last point of potential radioactivity entry for sample collection. The Alert alarms are set below the High alarms to act as precautionary warnings. The High alarm is set to ensure that the Offsite Dose Calculation Manual limits are not exceeded. Refer to Table 11.5-4 for the alert and high alarm setpoints, the range, and the sensitivity. Portions of the sample tubing located outside the building are adequately protected and routed to prevent the accumulation and freezing of condensate. The sample extracted by the isokinetic nozzle is passed through the fixed filter (particulate), charcoal filter (iodine), and fixed-volume (gaseous) detector assemblies and then through the pumping system for discharge back to the unit vent.Indication is provided on the radioactivity monitoring system Visual Display in the control room. This monitor provides a signal to the radioactive release report generation system described in Section 11.5.2.1.1
. 11.5.2.3.3.2Radwaste Building Ventilation Effluent Radioactivity MonitorThe radwaste building ventilation effluent radiation monitor, 0-GH-RE-10, continuously monitors for particulate, halogen, and gaseous radioactivity in the effluent duct downstream of the exhaust filter and fans. The sample point is located downstream of the last possible point of radioactive influent, including the waste gas decay tank discharge line. The flow path provides ventilation exhaust for all parts of the building structure and components within the building and provides a discharge path for the waste gas decay tank release line. These components represent potential sources for the release of gaseous and air particulate and iodine activities in addition to the drainage sumps, tanks, and equipment purged by the waste processing system.
CALLAWAY - SP11.5-15Rev. OL-195/12The monitoring system consists of a fixed filter particulate monitor, an iodine monitor, and gaseous activity monitor. The sample is extracted through an isokinetic nozzle to ensure that a representative sample of the air is obtained prior to release to the environment. After passing through the fixed filter (particulate), charcoal filter (halogen), and fixed-volume (noble gas) detector assemblies and the pumping system, the sample is discharged back to the exhaust duct. The sensitivities and alarm setpoints are given in Table 11.5-4. The Alert alarm is set below the High alarm to act as a precautionary warning. The High alarm is set to ensure that Offsite Dose Calculation Manual limits are not exceeded. Indication of this monitor is provided on the radiation monitoring system Visual Display in the control room. This monitor provides a signal to the radioactive release report generation system in the computer room (see Section 11.5.2.1.1
). This monitor will isolate the waste gas decay tank discharge line if the radioactivity release rate is above the preset limit when the waste gas discharge valve has been deliberately or inadvertently opened.11.5.2.3.3.3Laundry Decon Facility Dryer Exhaust MonitorThe Laundry Decon Facility Dryer Exhaust Monitor, 0-GL-RE-202, continuously monitors for particulate radioactivity in the effluent duct downstream of the exhaust filter and fans. This flow path provides ventilation exhaust for the Decon Facility Dryers.The air in this flow path is filtered before exhausted to the environment. The Laundry Decon Facility Dryer Exhaust Monitor measures actual plant effluents and not inplant conditions. The monitoring system consists of an off-line, fixed filter particulate monitor.The sample is extracted through an isokinetic nozzle to ensure that a representative sample of the air is obtained prior to release to the environment. After passing through the fixed filter (particulate) the sample is discharge locally.The sensitivities and alarm setpoint is given in Table 11.5-4. The alarm is set to ensure that the Offsite Dose Calculation Manual limits are not exceeded. The monitor will isolate the discharge path when measured levels are above the alarm setpoint or the monitor fails.11.5.2.4SafetyEvaluationThe control room ventilation monitors, the containment atmosphere monitors, the containment purge monitors, the containment LOCA atmosphere monitors, and the fuel building exhaust monitors are redundant, independent, seismic Category I, with Class 1E CALLAWAY - SP11.5-16Rev. OL-195/12power supplies. The control room and fuel building monitors will automatically switch from the normal to the emergency ventilation systems on high gaseous activity via the ESFAS. The containment atmosphere and containment purge monitors will automatically isolate the containment purge and stop the fans on high gaseous activity via the ESFAS. 11.5.3EFFLUENT MONITORING AND SAMPLINGAll potentially radioactive effluent discharge paths are continuously monitored for gross radiation level, except as described below. Liquid releases are monitored for gross gamma. Airborne releases are monitored for gross beta activity (particulates and noble gases) and gross gamma (iodines). The Laundry Decon Facility Dryer Exhaust is monitored for particulates.Airborne batch release for the Containment ILRT post-test vent may utilize pre-test grab samples in conjunction with ODCM calculation methodology, without the need for continuous monitoring. Refer to Table 16.11-4
.Laboratory isotopic analyses are performed on continuous and batch effluent releases in accordance with the Offsite Dose Calculation Manual requirements. Results of these analyses are compiled and appropriate portions are utilized to produce the Annual Radioactive Effluent Release Report in accordance with Technical Specification6.9.1.7. By a combination of the installed equipment described previously in Section11.5 and the installed equipment described in Section12.3.4, along with portable equipment described in Section12.5, and the emergency plan as described in Section 13.3
, the requirements of General Design Criterion 64 to monitor normal operations, anticipated operational occurrences, and postulated accidents are met.11.5.4PROCESS MONITORING AND SAMPLINGAll potentially significant radioactive systems which lead to effluent discharge paths are equipped with a control system to automatically isolate the discharge on indication of a high radioactivity level. These include the containment purge system, the fuel building ventilation system, and the gaseous and liquid radwaste systems. Batch releases are sampled and analyzed in accordance with Offsite Dose Calculation Manual requirements, in addition to the continuous effluent monitoring. By means of the continuous radioactivity monitors mentioned above and their associated control valves, and due to the extensive sampling program described in the Environmental Report, General Design Criterion 60 and the Offsite Dose Calculation Manual requirements are met with regard to the control of releases of radioactivity to the environment.

CALLAWAY - SA11.2-1Rev. OL-13 5/0311.2.3.2Release Points The Callaway Plant normal effluent releases as calcul ated per the guidance in Section 11.1.1, were considered for evaluat ing the local surface-water environment in dispersing, diluting, or otherwise concentrating radioactive effluents as related to existing or potential future water users. Since routine plant releases will be discharge directly to the Missouri River by pipeline, there will be no impact on the local ground-water system(s) from this source.11.2.3.3Dilution Factors11.2.3.3.1Description of Surface-Water Analytical ModelA steady-state stream tube model was utiliz ed for evaluating t he transport of radionuclides in the Missouri River downstream from the Callaway Plant effluent release point. This model, based on Equation 17 in Regulatory Guide 1.113 (NRC, 1977),
applies to nontidal ri ver/stream systems.
For evaluating radionuclide transport in the Missouri River from plant effluent releases, flow was assumed to be steady and uniform. Application of the steady-state stream tube model for evaluating plant ef fluent releases was based on simplifying assumptions of idealized rectangular stream channel geometry and velocity in the Missouri River under assumed steady and uniform fl ow conditions. The Misso uri River is gauged and streamflow in the immediate vicinity of the Callaway Plant site, and only channel velocity distributions are know n several miles downstream at the USGS gauging station at Hermann.For steady open-channel flow, K y can be determined from hydrodynamic properties of the channel by using Elder's empirical formula (NRC, 1977):
where:The dimensionless constant, , has a value of approximately 0.23 for straight natural stream channels (NRC, 1977). For curved channels, however, secondary flows can lead to increased lateral mi xing, and the value of is larger (Fischer, 1969; Yotsukura et al., 1970; Sayre and Yeh, 1973). Fischer (1969) has demonstrated that the lateral mixing coefficient can be increased in bending streams, varying inve rsely as the square of the Ky = u*d(11.2-1)d=River depth;u*=Shear velocity; and=A dimensionless constant.
CALLAWAY - SA11.2-2Rev. OL-13 5/03radius of curvature. The dimensionless parameter, , as determined by field investigations, is reportedly 0.6 to 0.7 for a gradually curving reach of the Missouri River near Blair, Nebraska (Yotsukura et al., 1970). Another fiel d investigation conducted near Brownsville, Nebraska for a test reach containing a ve ry sharp bend reported average and maximum values of equal to 3.3 and 10, respecti vely (Sayre and Yeh, 1973).
The certified computer program, DISPERN, was used for performing the routine effluent analysis. This program is based on the steady-state stream tube model.11.2.3.3.2Selection of Surface-Water Model ParametersA summary of parameters used in the routine effluent analysis is presented in Table 11.2-1. Representative channel geometry parameters of the Missouri River for 50 miles downstream of the Callaway Plant effluent discharge pipeline are noted for the estimated average flow conditions. Average flow conditions are discussed in Section 2.4 and are based on stage-discharge relationships developed for the Missouri River at the Hermann gauging site (see Figure 2.4-10
) and near the Callaway Plant site (see Figure 2.4-12), hydrographic survey data from the U.S. Army Corps of Engineers (1978), and hydrologic analysis for river channel variables.In the analysis, methods for evaluating the lateral turbulent diffusion coefficient, K y, were reviewed. The mi nimum value of , 0.23 for determining K y, was not considered appropriate to use since it app lies specifically to straight natural stream channels and ignores secondary flows which have been experimentally found (as in the Missouri River) to lead to increased latera l mixing. A value of equal to 0.65 for determining K y was adopted, as found experimentally for a gradually curving r each of the Missouri River upstream of the Callaway Plant site.11.2.3.3.3Results of Analysis In the analysis for radi onuclide transport in the Miss ouri River from the estimated Callaway Plant annual liquid effluent releases (see Section 11.1.1 of Standard Plant),
dilution factors and tran sit times were predicted from the plant effluent discharge to a distance 50 miles downstream. These are presented in the computer output summary in Table 11.2-2 and 11.2-3. Values are indicated at various cross-stream distances from the near shore for incremental distances beginning at 1 foot.In tables 11.2-2 and 11.2-3, the dilution factors are present ed at the given cross-stream distances from the near shore out to within 50 feet of where the fart hest influence of radionuclide transport is estimated.11.2.3.3.4Water Usage For noting liquid pathways to man and for evaluating potential impacts from effluent releases from the Callaway Plant on man and other biota (Section 11.2.3.4
), Missouri CALLAWAY - SA11.2-3Rev. OL-13 5/03River water users were identified along its entire length (115 rive r miles) downstream from the Callaway Plant site. Dischargers we re also identified.
These are discussed in Section 2.4 and are identified in Tables 2.4-18 and 2.4-19. Locations of these water withdrawals and water discharge points are shown on Figure 2.4-8
. The closest municipal user of Missouri Ri ver water downstream from the Callaway Plant site is St.
Louis City (Howard Bend), and its water intake is locate d at Missouri River mile 36.8, some 78 river miles downstream of the Callaway Plant site. The cities of Hermann, New Haven, and Washington, all within 50 miles downstream of the plant effluent discharge pipeline, are the majo r dischargers to the Missouri River; however, these communities derive their municipal water suppliers from deep wells only. Two known irrigation users that utilize Missouri River water downstream of the Callaway Plant site have intakes located at Missouri River mile s 64.5 and 61.4, the nearest of which is located 51 river miles downstream from the plant effluent dischar ge pipeline. The Union Electric Company also withdraws water from the Missouri River at river mile 58.1 and discharges downstream at river mile 57.9, just below the city of Washington.Since water users upstream of the Callaway Plant site can alter flows at and downstream of the site and because relocation of contaminated and potentially contaminated materials upstream in the ph ysical environment (s uch as occurs in dredging operations) could potentially affect the conditions near the site (NRC, 1977 and 1976), Missouri River water users and dischargers upstream from the site were also sufficiently identified to the best extent possible.
These are shown on Figure 2.4-9
. No potential contaminant source areas were identified. Also, NRC Regulatory Guide 1.113 (1977) suggests identification of the follo wing features in relation to a nuclear plant site:
(1) surface water usage [Use types include water, irrigati on, process water (consumed by such users as breweries and soft drink manufacturers), recreation areas, and fisheries. Ground
-water users with wells w hose zones of influence extend to streams should also be included (NRC, 1977).] upstream and downstream of the plant site, (2) major tributaries and their junctions, (3) streamflow gauging stations (including their periods of record), and (4) major reservoirs and diversions upstream and downstream of the plant site.
Approximate contributing dr ainage areas and types of water use for all points identified should be s hown on the diagram or tabulated separately.
Section 2.4.1 presents a description of surface and ground-water uses in the region surrounding the Callawa y Plant site, based on the best available data, both published and unpublished. Descriptions of the Missouri River and its major tributaries, streamflow gauging stations, major reservoirs, and ground-wa ter characteristics in this region are discussed in Section 2.4.1
. All of the above were cons idered for modeling the Missouri River under present condition s and for evaluating the impacts on man and other biota from effluent releas es from the Callaway Plant (refer to Section 11.2.3.4
).
CALLAWAY - SA11.2-4Rev. OL-13 5/0311.2.3.3.5Ground-Water Models Since routine plant releases wi ll be discharged directly to t he Missouri River by pipeline, there will be no impact on the local ground-water regime fr om this source. Therefore, effluent releases were not c onsidered in evaluating the lo cal ground-water environment in dispersing, diluting, or ot herwise concentrating radioactive effluents as related to existing or potential fu ture ground-water users.11.2.3.4Estimated Doses11.2.3.4.1Dose Rate Estimates for Biota Other than ManFrom considerations of the exposure path ways and the distribution of facility-derived radioactivity, dose rate estimates to local biota have been formulated through the use of the LADTAP II comput er code. This code is based on the methodology presented in Regulatory Guide 1.109, which uses the standard ICRP model for computation of effective radionuclide decay ener gies and result ant dose factors.
Doses to aquatic flora and f auna can be calculated from a knowledge of concentrations of radionuclides in the Missouri River 0.05 miles downstream of the discharge. Based on radionuclide concentrations present and bio-accumulation factors in Table A-8 in Regulatory Guide 1.109, doses to fish and s hellfish living continuously in the section of the Missouri River 0.05 miles downstream of th e discharge of the pl ant were calculated to be 2.19 mrad/yr and 3.95 mrad/yr respectively.Doses to terrestrial and semi-aquatic animals from the radionuclides in the gaseous and liquid effluent and direct radiation from the plant are expected to be less than or equal to those calculated for man.
Dose rates due to liquid radioactive effluents from the Callaway Plant were calcul ated for the muskrat and racc oon, a semi-aquatic herbivore and a terrestrial omnivore, respectively. Total exposures were 7.10 mrad/yr and 0.845 mrad/yr for the muskrat and raccoon, respectively.
It was assumed that the animals obtained all of their food and water from the shore and waters of the Miss ouri River 0.05 miles downstream of the Callaway discharge. The doses to such animals as migrating ducks, bald eagles, etc. whose pr esence within 50 miles of t he site is on a sporadic or seasonal basis is expected to be consider ably less than doses to animals which inhabit the area on a continuous basis.
The dose to organisms other than man will be a very small percentage of that resulting from naturally occurring radiation.11.2.3.4.2Dose Rate Estimates for Man
Dose rates to individuals were calculated for drinking water, fish consumption, and recreational activity pathways.
Assumptions, including point of exposure, are described for each pathway in the following paragraphs; the calculated liquid pathway doses are CALLAWAY - SA11.2-5Rev. OL-13 5/03summarized in Table 11.2-4
. Releases calculated using the guidance presented in Section 11.1.1 were used.
Crop irrigation is not considered a potential pathway of liquid effluents to man. This is because most water used for irrigation by local farmers comes from small streams in the vicinity rather than the Missouri River.No drinking water is drawn from the Missouri River withi n 50 miles downstream of the Callaway Plant discharge. Ne vertheless, the dose to an individual obtaining his entire annual water requirements from the Missouri River 0.05 miles downstream of the plant discharge was calculated. The maximum calc ulated dose to a singl e organ from this pathway was calculated to be 9.39 x 10
-2 mrem/yr to an infant's liver; maximum total-body dose was ca lculated to be 7.27 x 10
-2 mrem/yr to an infant.
Radionuclides released from t he plant were assumed to be immediately available for uptake by fish. In lieu of site specific fish consumption data the values recommended by the NRC for use with the LADT AP II program were used.
The maximum predicted dose of 0.573 mrem/yr to an adult liver was calculated from the fish consumption pathway due to fish caught 0.05 miles downs tream of the plant discharge. The maximum total-body dose calculated was 0.434 mrem/yr to an adult.
The Missouri River has been designated unsuitable for swimming by the State of Missouri but of suitable qualit y for wading or boating. Pote ntial recreational use of the Missouri River does, however, ju stify calculation of shorel ine activity doses. The maximum calculated dose to a single org an from shoreline re creation 0.05 miles downstream of the plant discharge was 1.78x10
-3 mrem/yr to the skin on a teenager. A maximum total body dose of 1.53 x 10
-3 mrem/yr was calculated at the same location.
Examination of Table 11.2-4 reveals that, based on the dos e calculation assumptions described above, the liquid pathway of primary importance in individual total-body exposure is ingestion of fish caught in the Missouri River downstream of the discharge structure. Exposure from sh oreline activities will generall y be of less importance. No drinking water pathway exists within 50 miles of the plant.11.2.3.4.3Estimated Population Doses
Population doses were calculated for fish ingestion, shoreline, and boating exposure pathway. As explained in Section 11.2.3.4.2, the drinking water, swimming, and crop irrigation exposure pathways are not expected to contribute a measurable percentage to the population doses within 50 miles downstream of the Callaway Plant on the Missouri River.The dose to the population from fish ingestion was based upon a fish harvest of 4.58 x 10-6 kg/yr from the Missouri Ri ver from the plant dischar ge structure to 50 miles downstream, and includes both comm ercial and sport fish harvest.
CALLAWAY - SA11.2-6Rev. OL-13 5/03Calculation of populat ion doses from recreat ional exposure was based on usage rates taken from data compiled by the Army Corp or Engineers (Recr eational Development Missouri River Rulo, Nebraska, to the Mouth, June 1978).Fish ingestion accounts for more than 95 percent of the total man-rem dose from the Missouri River. Exposure from recreational activity is expec ted to contribut e the other 5 percent of the total man-rem dose.
