3.2.5.1 Conductivity Monitoring Each autoclave is provided with redundant conductivity cells to monitor the atmosphere within he autoclave to detect the presence of any HF that would result from UF. that might leak from a cylinder. De i
l conductivity cell constandy withdraws a portion of the steam vapor, condenses it, and measures the electrical conductivity of the condensate. UF. leakage into the autoclave will form HF,.which results in high l
conductivity, which in tum operates an interlock system to isolate. the autoclave by closing the redundant inlet l
seam valves, evacuation valves, feed line valves, vent valves, condensane drain valve:, and conductivity valves to contain any UF. release products within the autcclave. Procedural controls dictate that at least one of the conductivity cells must be in operation at all times to detect any small leaks of UF..
3.2.5.2 Water Inventory Control As mentioned in Section 3.2.3, the maximum pressure generated in an autoclave from an accidental UF.
release and subsequent reaction with the available water is best controlled by limiting the water in the autoclave j
shell. Pui-bnt condensate level probes, LE-527 "A and LE-527 "B, are mounted in the 3-in. drain pipe slighdy below the autoclave. These probes are refened to as the primary condensate probes. If the ultrasonic j
l probes detect high water levels, the steam supply isolation valves close to limit the total water in the autoclave.
l To prevent false alarms, a time delay feature requires the system to be in the alarm state for five seconds before the alarm will initiate steam valve and thermovent line block valve closure. This system has been designated a system required to be included in the technical safety requirements (TSR) (see Figure 3.2-2).
A secondary condensate probe, located lower in the condensate drain line provides an alarm before the condensae level reaches the primary probes. The secondary system is not a TSR system.
j.- -
3.2.5.3 Autoclave Steam Pressure Control The autoclave steam pressure control system is required to be included in the TSR and is used to stop the l
steam tiow to the autoclave while heating a cylinder prior to reaching temperatures that could result in reaching L
its maximum allowable working pressure. If the autoclave pressure reaches 8 psig, the steam pressure control system closes the steam isolation valves and the thermovent line block valve and sounds an alarm. The components of this system are the pressure transmitters PT-514 and PT-515, pressure switches PSH-514 and PSH-515, steam supply isolation valves PV-520 and XV-524, and associated relays, solenoids and switches (see Figures 3.2-2 and 3.2-4). The thermovent line block valve is not covered by a TSR since the isolation function is accomplished by closing the steam isolation system.
I 3.2.5.4 Autoclave High Pressure Isolation System i
The autoclave high pressure isolation system causes the autoclave to gc into the containment mode and sound an alarm if the internal pressure of the autoclave reaches 15 psig. In addition, the system disables the l
. hydraulic system required to open the autoclave shell preventing the autoclave from opening until the alarm condition has been cleared. This system is identified as a system required to be included in the TSR. De components of this system include the autoclave shell, head, and locking ring, pressure transmitters PT-514 and PT-515, pressure switches PSHH-514 and PSHH-515, containment block valves XV-503, CV-504, XV-505, CV-510, CV-511, XV-516, PSV-517, PSE-518, PV-520, XV-524, PV-525, XV-528, FV-529, XV-532, CV-533, and XV-565, and associated relays and switches, see Figures 3.2-2 and 3.2-4. All containment valves / pressure boundary devices are capable of being leak tested with a full differential pressure.

SAR-PGDP May 31,1996 Rev.3 3.2.5.5 Autoclave Relief System The autoclave relief system consists of the autoclave rupture dise PSE-518 and relief valve PSV-513, which vents pressure in excess of 200 psig (MAWP of the autoclave) to the atmosphere through a vent line through the roof (see Figure 3.2-2). The relief valve closes when the autoclave pressure drops below the MAWP to limit the amount of any release. This system is required to be included in the TSR.
3.2.5.6 UF. Detudon System Although the autoclaves are designed to contain a UF. release, UF. detection heads are installed above the autoclave head ring, the heated housmg at the autoclave head, above the jet station piping, and in the piping trench. These systems consist of one detector each and will detect any leakage from the autoclave seal, the heated housing piping, the jet station piping, or the piping trench. If a leak is detected, an alarm is sounded locally at each autoclave and on the UF detecter alarm panel. The UE de'ection systems located for the heated housings, jet station, and piping trench r.re designated as a system required to be included in the TSR (see Figures 3.2-5 and 3.2-6).
3.2.5.7 Attoclave Manual Isolation System The autoclave manual isolation system contains three manual push buttons, one at the Operations Monitoring Room door, one at the crane bay exit near the local cylinder yard, and one in the ACR. When one of these buttons is pressed, each facility autoclave is placed imo containment (at least one isolation valve on each isolable autoc!zve penetration closed). The buttons are used upon confirmed UF. outleakage to mitigate the release.
3.2.5.8 Operational Systems The following operational systems are intended to prevent challengs to the safety systems. Although these systems are not relied upon to provide safety functions, they do prrsvide diversity while performing their intended function ofimproving autoclave operations.
The low cylinder pressure system closes the steam isolation valves and the thermovent line block valve l
and sounds an alarm if the cylinder pressure fails to reach 24 psia in 13/4 hours. The components of this system are the timer (internal to the programmable logic controller), pressure *ransmitter PT-502, pressure switch PSL-502, steam supply isolation valves PV-520, XV-524, and thermovent line block valve XV-565, and associated relays, solenoids, and switches.
The high cylinder pressure system closes the steam isolation valves and sounds an alarm if cylinder pressure exceeds 90 psia. The components of this system are the pressure transmitter PT-502, pressure switch PSH-502, steam supply isolation valves PV-520, XV-524, and thermovent line block valve XV-l 565, and associated relays, solenoids, and switches.
l The cylinder pressure relief system relieves pressures in excess of 100 psig (lowest MAWP of the
=
cylinders heated) from the feed cylinder and closes the steam isolation valves and the thermovent line i
I block valve. The components of this system are the 100 psig relief discs, PSE-506 and PSE-508, 3.2-10 V

,d Rev.3 The building is constructed of stmetural steel with build-up roof, cement-asbestos, and metal siding and has concrete floor s' abs and foundations. Seismic design consideration is in accordance with Energy Research and Development Agency (ERDA) Criteria Appendix 6301 and Universal Building Code (UBC) Zone 3.
Ventilation for the general work area in C-300 is provided by one 50,000 cfm supply 'an and eight 50,000 cfm exhaust fans. He supply fan is in operation prior to draining UF to the transfer station at the basement level. The fan and UF. drain valve are interlocked to ensure ventilation in this area. Louvers provided in the building siding aid ventilation. Each autoclave is connected to a small 1,500 cfm exhaust system that provide local ventilation for occasional small releases of UF, exhaust that may occur when making or breaking pigtail connections. Operation of the exhaust system is actuated by a manually operated switch located between I
autoclaves 2 and 3, and the exhaust effluent is passed through a high efficiency particulate filter for removal I
of any uranium particles prior to venting to the atmosphere. There is an exhaust bood over the transfer filling j
station. The effluent from this hood is also passed tnrough high efficiency particulate filters prior to release to the atmosphere.
3 3.6.3 Autoclaves C-360 has four containment-type autoclaves used to heat cylinders for sampling and transferring UF..
i Each autoclave is a steam-heated pressure vessel with an MAWP ot 150 psig and with the necessary instmmentation for the sensing and containment of UF releases that might occur when a cylinder containing q
UF. is being heated, sampled, or transferred. These units are approximately 23 ft long with an internal i
4 diameter of 8 ft and are mounted with their long axis horizontal. One section of the autoclave (head) is permanently fixed in position, while the remainder of the vessel (shell) is movable to perinit the introduction and removal of UF, cylinders. The cylindrical autoclave is parted ncrmal to its axis about 3% ft from one head. The shell section is mounted on a wheel and track system, which allows opening and closing of the autoclave by translation down its main axis. This motion is provided by a hydraulic ram. When in the closed position, the shell is secured to the head by a hydraulically operated locking ring and a captured 0-ring seal.
To protect personnel from potential steam burns, an interlock prevents opening the autoclave shell if pressure in the autoclave exceeds 1.25 psig. Travel time to fully open the autoclave is approximately one minute.
I In the open position, each autoclave has an extended length of about 39 ft and an opening 15 ft long through which a cylinder is placed on the horizontal support chain inside the autoclave. The overhead crane is used to position the cylinder. The support chain is pcwer-driven to permit the cylinders to be rotated for sampling and transfer operations. When the autoclave is in the open position, a tilting mechanism can be used to elevate the plugend of the cylinder a distance of about 18 in. to enhance liquid transfer from the cylinder inside the autoclave to the receiving cylinder positioned at the withdrawal station. An air buffer flow to the actuator motor and cylinder roll motor is maintained to keep steam out of the electrical circuits and aid in cooling the motors and circuitr. A roll interlock system prevents rotation of the cylinder. The pigtail is pressurized by monitoring the UF. manifold pressure.
Service lines that penetrate the autoclave are controlled by redundant isolation valves which close automatically when the autoclave goes into containment to prevent the eccape of reaction products in the event of a release inside the autoclaves. Penetrations through the head include the steam cupply line, UF.

Figure 3.6-3 provides a simplined schematic of a C-360 autoclave and 6e associated piping.
'Ibe following valves / barriers isolate service lines:
l Steam supply line - valves XV *53 and FV *05, and FV *24.
l Conductivity cell sample line - valves FV *00 and FV *10.
UF sample transfer line - valves XV *48, XV *51, and PL *33.
l Condensate drain line - valves FV *03 and FV *46.
Buffer air line - valves XV-Sil *A, XV-Sil *B, XV-511 *C, TP-Sil
- and check valve CKV-511 *.
l Vent line - valves FV *00 and XV *34, vacuum breaker valve PSV *20 and PSE *32.
l UF. drain line - valves XV *50, XV *52, FV *47, and PL *35.
l Drain line to sample cabinet valves XV *49 :nd XV *52.
=
Each autoclave is designed to withstand the pressure developed by the exothermic reaction of UF. with the steam vapor and the condensate present. The presstires generated in an autoclave are a function of the autoclave free-volume and total water inventory (see Section 4.2.3).
The C-360 sample-transfer autoclaves have a 1,100 tf volume and are designed for a 150 psig maximum allowable working pressure at 235'F. To ensure the maximum allow?ie water inventory the autoclave is maintained below the amount necessary to overpressunze the autoclave in the event of a UF. release.
l Redundant condensate high level prnbes, LE *07 and LE *08, are mounted at the sarne elevation in the condensate drain slightly below te autoclave floor. Any abnormal accumulation of condensate in the drain l
line reaching 6e level of tese probes automatically shuts te steam isolation valves, XV *53 and FV *05, and the thermovent line block valve FV *34, and prevents the addition of more water.
As a protection agamst catastrophic overpressure, each autoclave is provided with a rupture disc in series with a pressure relief valve set at 150 psig. In the event of a UF. release in which a failure of the condensate level system had allowed the autoclave to accumulate an excessive water inventory, the resulting overpressure would be relieved to the atmosphere by a vent line above the C-360 roof. The autoclave would then contain all reaction products remaining at a pressure below the set point of the relief valve.
Stearn is introduced into 6e autoclave as a heating medium and to maintain cylinder temperature. In the event of a UF. release, reaction products of UF. and water are detected by redundant conductivity cells which constantly monitor a sample of the autoclave atmosphere. The conductivity cells are intended to detect small releases of UF. that do not generate a significant pressure rise within t!.s autoclave. The cell is extremely sensitive to the HF component of 6e UF. reaction with water and detects concentrations of only a few parts per million. When triggered, this cell initiates an autoclave containment signal that closes the steam supply j
line, vent line, UF. sample transfer line, condensate drain line, and buner air line isolation valves. If the conductivity cell detects reaction products in the steam condensate, the condensate drain line valve l
automatically closes. Operator action is required to switch 6e discharge path from se storm sewer to two condensate holding tanks. Tests of tis cell by controlled release of HF into an operating autoclave have shown the response time to be in the order of 30 to 60 seconds.

3.6.7.7 Operational Systems The following operational systems are intended to prevent challenges to the TSR-required systems.
Although these systems are not relied upon to provide safety functions, they do provide diversity while performing their intended function of improving autoclave operations.
The low cylinder pressure system closes the steam supply isolation valves and sounds an alarm if te cylinder pressure fails to reach the required pressure of 24 psia within the prescribed time (not greater than 13/4 hours). The components of this system are the timer, pressure transmitter PT *12, current to pressure transmitter PY *12C, pressure switch PSL *12, steam supply isolation valves XV *53 and FV *05, and associated relays, solenoids and switches.

Re high cylinder pressure system closes the steam supply isolation valves and the thermovent line block valve and sounds alarms if the cylinder pressure reaches or exceeds 90 psia. The components of this system are the pressure transmitter PT *12, current to pressure transmitter PY *12C, pressure switch PSH *12A, steam supply isolation valves XV *53 and FV *05,thermovent line block valve FV *34, and associated relays, solenoids and switches.
The cylinder pressure relief system relieves pressures in excess of 100 psig from the feed cylinder to the cylinder relief tanks, and closes the steam supply isolation valves and the thermovent line block valve.
The components are the 100 psig relief discs PSE *13 and PSE *16 on the sample manifold, pressure transmitter PT *14, pressure switches PSH *14 and PSL *14, and steam supply isolation valves XV *53 and FV *05, thermovent line block valve FV *34, and associated relays, solenoids and switches. The pressure between the rupture discs is maintained between 9.5 and 19.5 psia.
The autoclave opening prevention system is used to prevent the opening of an autoclave when the internal
]
pressure exceeds 1.25 psig and gives a visual indication. System components are the pressure transmitter PT *15, pressure switch PSL *15, and associated relays, solenoids and switches.
The cylinder tell interlock prevents the rolling of a cylinder while the pigtail is pressurized. This system l
is intended to supplement administrative controls which prohibit rolling or tilting a cylinder while it is connected to the manifold. He components of this system consist of the pressure transmitters, pressure switches, and associated relays, solenoids and interlocks.

Rev. 3 3.6.8 Liquid Drain Station Enclosure He greatest potential for a liquid UF. release in the basement area occurs at the liquid transfer station.
In 6e event of 6is low probability accident invol: ing the gross failure of the pigtail connection to a daughter cylinder, the closest path of egress from the dram station is by the stairways east and north of the transfer station.
A sheet metal enclosure around the transfer station confines releases to a smaller area, thus making it safer for emergency evacuation of personnel. A release will still exit the area due to the open elevator shaft along the east side of 6e room. A double door to the north is equipped with panic hardware and has automatic door closers held in 6e open position. Activation of the UF. release detection system at the drain position will release the doors.
3.6.9 Cylinder Handling The movement of cylinders containing liquid UF. is minimized to reduce the potential for a loss of containment. Cylinder handling equipment and facilities are discussed in the following sections.
3.6.9.1 Scales, Scale Carts, Hydraulic Lift and Elevator The cylinder weighing system includes two scales wi6 maximum capacity of 40,000 lb each, graduated to read and print in I lb increments. One scale, referred to as the accountability scale, is used exclusively for weighing incoming and outgoing cylinders. The other scale provides continuous weighing of the contents of a cylinder being filled with UF.at 6e liquid transfer drain station. The transfer scale also serves as a backup for the accountability scale. A complete electronic system is integrated with the mechanical weighing system on the transfer scale to provide electronic readout by means of a load cell arrangement read on a digital indicator. A high weight limit on the transfer scale will automatically close a block valve on the UF. transfer line and sound alanns in the C-360 supervisor's office and at the control panel in the C-360 !aboratory when a predetermined setting is reached.
Both scales have steel-decked platforms with recessed rails to allow a 40,000-lb capacity scale cart contaming the UF. cylinder to be moved on and off the scale for weighing without removing the cylinder from the scale cart.
UF. cylinders are moved from the storage yard into the building by overhead crane and placed on a scale cart at the autoclave work level where the cart is moved onto the scales and weighed. The weighed cylinder can then be placed in one of the four autoclaves by using the overhead crane, or moved back to the storage yard by reversing the steps mentioned above. A hydraulic lift ("levelator") is used to lower cylinders comammg liquid UF. from 6e autoclave work level to the ground level where the scale cart is moved outside to the storage area. The hydraulic lift has a net travel of 4 ft and a net lifting capacity of 40,000 lb. Automade rail chocks are provided on the outboard side of the platform to prevent rolling of the scale cart during movement of the platform.
