3.2.5.1 Conductivity Monitoring Each a'itoclave is provided with redundant conductivity cells to monitor the atmosphere widiin the autoclave to detect the presence of any IIF that would result from UF, that might leak from a cylinder. The corductivity cell constar11y withdraws a portion of the steam vapor, condenses it, and measures the electrical conductivity of the condensate. UF, leakage into the autoclave will form liF, which results in high corductivity, which in turn operates an interlock system to isolate the autoclave by closing the redundant inlet steam valves, evacuatkin valves, feed line valves, vent valves, condensate drain valves, and conductivity valves i
to corsain any UF, release products within the autoclave. 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 mnimum pressuie 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 shell. Redurdant condensate level probes, LE 52'i "A and LE 527 "B, are mounted in the 3 in. drain pipe slightly below the autoclave. Dese probes are referred to as the primary cordensate probes. If the ultrasonic protes detect high water levels, the steam supply isolation valves close to limit.he total water in the autoclave.
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 :losure, nls system has been designated a system required to be included in the technical safety requirements (TSR) (see Figure 3.2 2).
A secordary condensate probe, located lower in the condensate drain line provides an alarm before the condensate level reaches the primary probes. The secondary system is not a TSR system, b
3.2.5.3 Autoclave Steam Pressure Control v
De autoclave steam pressure cortml system is required'to be included in the TSR and is used to stop the steam flow to the autoclave while heating a cylirder prior to reaciung temperatures that could result in isaching its maximum allowable working pressure, if the autoclave pressure reaches 8 psig, the steam pressure control sy' tem 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 switetes PSii 514 and PSil-515, steam supply isolation valves PV-520 and XV-524, and associated relays, solencids and switches (see Figures 3.2-2 and 3.2-4). De thermovent line block valve is not covered by a TSR sace the isolation function is accomplished by closing the steam isolation system.
3.2.5.4 Autoclave Illgh Pressure Isolation System De autoclave high pre.sure isolation system causes the autoclave to go into the containment mode and sourd an alarm if the internal pressure of the autoclave reaches 15 psig. In addition, the system disables the hydraulic system required to open the autoclave shell preventing the autoclave from openirg until the alarm condition has been cleared, nis system is identified as a system required to be included m the TSR. He components of this system include the autoclave shell, head, and locking ring, pressure traasmitters PT 514 and PT 515, pressure switches PSHil 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 vahts/ pressure boundary devices are capable of being leak tested with a full differential pressure.

SAR-PGDP November 1,1997 Rev.18 3.2.5.5 Autoclave Relief System The autoclave relief system consists of the autoclave rupture disc 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). De relief valve closes when the autoclave pressure drops below the MAWP to limit the amount of any release his system is required to be included in the TSR.
3.2.5.6 UF, Detection System Although the autoclaves are designed to contain a UF release, UF detectbn heads are installed above the aucclave head ring, the heated housing at the autoclave head, above the jet station piping, and in the piping trench. Rese 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 le sounded locally at each autoclave and en the UP detector alarm panel. The UTg detection systenu located for the heated housings, jet station, and piping trench are designated as a system required to be incluced in the TSR (see Figures 3.2 5 and 3.2-6).
3.2.5.7 Autoclave Manual Lsolation System De autoclave manual isolation system contains three manual actuation devi'es, one at the Operations Monitoring Room, ore at the crane bay exit near the local cylinder yard, and one in the ACR. When one of these devices is actuated, containment valve closure is initiated for e.ach facility autoclave, ne sycem is used upon confirmed UT. outleakage to mitigate the release.
3.2.5.8 Operational Systems The following operational systems are intended to prevent challenges to the safety systems. Although these systems are rxx relied upon to provide safety funcuons, they do provide diversity while performing their intended function of improving autoclave operations.
9 ne low cythxler pressure system closes the steam isolation valves and the thermovent line block valve e
and soutsis 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 transmitter PT-502, pressu c 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-565, and associated relays, solenoids, and switches.
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 block valve. The components of this system are the 100 psig relief discs, PSE-506 and PSE-508, 3.2-10

SAR PGDP July 26,1996 Rev.4 Because the cylinder valve is always in the 12 o' clock position, aiy UF. released from a leak at the valve er pigtall connection would be in the vapor phase. The UF, would react with the available water to form IIF which would be detected within 30 see by the conductivity cells. If the leak were small, the autoclave pressure would not rise rapidly and the conductivity cells would detect the leak and sound an alarm locally and in the control room. A loss of power or a containment sips! generated either by the conductivity cells or the autoclave high pressure isolation safety system will also case the cylinder valve to automatically close, thus terminating the UF. release into the autoclave. The cylindar valve is closed with an air-operated cylinder valve closer at each autoclave, it is expected that the cylinder valve will close in no more than 2 minutes. The amount of UF.
released inside the autoclave would depend on the size of leak, but would be no more than 80 lbs/ min.
The only reaction products to leave the autoclave would be those exiting through the condensate drain line (and the vent line during initial heatup) in the time required to detect the release and isolate the autoclave. Any release large enough to cause a significant release via the condensate sample line would also cause a pressure great enough to actuate the autoclave UP. high pressure isolation safety system.
The autoclave steam pressure control safety system utilizes pressure sensors which are set to close the steam inlet valve if autoclave pressure exceeds 8 psig. If the autoclave pressure continues to rise, the
'4utoclave high pressure isolation safety system will put the autoclave into containment at 15 psig. All redundant block valves will close within 10 sec following the signal from the pressure sensors.
Figure 4.3 2, from the Barber calculations, shows that during a large release the autoclave pressure rises rapidly, reaching a maximum in less than 30 seconds.8 in this case, the use of a pressure sensor (3
provides a more rapid isolation tbn that obtained from a conductivity cell. Because the Barber calculations are based on a completely closed vessel, tests have been conducted to prove that the pressure ri>e is fast enough to actut:e a pressure sensor for rapid isolation of the autoclave, despite the pressure loss caused by the open condensate drain and conductivity cell sample line isolation valves. These valves would be open during operation. Figure 4.3-3 shows that pressure decay characteristics of a typical autoclave from 90 psig with the drain and sample line valves open. Figure 4.3-4 shows the pressure decay fmm 50 psig with selected valves closed. Consequently, the autoclave isolation system is initiated by the pressure sensor for those releases having a large and rapidly rising pressure for which the reaction time of the conductivity cell could be marginal, and by the conductivity cell for those releases which are small and result in a pressure below the trip point of the pressure sensor.
l The amount of reaction products lost through the condensate drain line would be too small to present any health hazard; The amount of UP./ll O reaction products released through the condensate drain is 2
GV 4.3 3
C AR PGDP November 1,1997 Re v.18 not vastly different regardless of whether the incident is detected and terminated by the conductivity system or by the autoclave high pressure isolation system, he following discussion assumes the conductivity system fails.
For very small releases from the cylinder (2 lb/ min UF.), the pressure rise would be slow, resulting in the condensate drain remaining epen for a longer period of time until the pressure rises to a level sufficient to actuate either the autoclave steam pressure control or the autoclave high pressure isoladon system.
liowever, because of the low refer rate, a relatively small quantity of UF./Il O reaction products are 2
available for release out the conder ate drain, ne estimated release of UF./Il O reaction products through 2
the condensate drain line is 0.1 md UO,F, if the conductivity system detects and terminates the incident, and 2.9 pounds UO,F, if tir ave high pressure isolation system detects and terminates the incidem.
As the UF, release rate i m the cylinder / pigtail increases, the amount of UF. /11 O reaction products available for release increases ac. dingly, llowever, the pressure transient would le correspordingly more rapid, resulting in quicker detection and termination by the autoclave high pressure isolation system.
Consequently, the cotxlensate drain line would be open for a shorter period of time, ne estimated release of UF./II 0 reaction products through the condensate drain line for a release rate of 20 lb/ min UF. from the 2
cylinder is 2.4 pounds of UO,F,if the corductivity system detects and terminates the incident, and 2.4 pounds UO,F, if the autoclave high pressure isolation system detects and terminates the incident. At release rates greater than 20 lb/ min UF, from the cylirder, the autoclave high pressure isolation system detects the incident more rapidly, ard the amount of UO,F, released decreases (to 0.2 pounds UO,F, at an 80 lb/ min UF. release rate from the cylinder).
The feed autoclaves are designed whh a maximum allowable working pressure (MAWP) of 200 psig.
Assuming full UF, reaction wi,h the maximum allowable water inventory in the autoclave, there would be no release to the aunosphere. Calculations show that following an initial pressure spike to 103 psia, autoclave pressures will not exceed 87 psia as a result of the accident postulated above. Should the UF react with an excessive amount of water, the autoclave is protected from overpressurization by the autochve pressure relief safety system. His sys.:m consists of a rupture disk atx! relief valve which vent reaction products to the atmosphere. 'Ihe relief system is sized to prevent pressures from exceeding i10% of the MAWP. The relief valve recloses at the MAWP to limit any potential release.
De likelihood of such an accident happening in an autoclave is considered to be low due to the administrative controls concerning testing of cylinder valves, pigtails, and connections.
1 A release resulting from a valve or pigtail failure with the autoclave open would be detected by the UF, release detection system Iocated above the autoclave locking ring and alarmed in the local area, the ACR, and C-300. An autoclave closure button is available near the autoclave head which must be coritinuously depressed to close the autoclave. De administrative controls referenced above are relied upon to prevent releases with the autoclave open.
A release from t line outside the autoclave would be detected by the UF. release detection system located in the heateu nousing, at the jet stations, and in piping trenches and alarmed in the local area, the ACR, and C 300. The autoclave manual isolation system provides a remote isolation device at the feed i
facility operations monitoring room (OMR), at the cylinder yard crane bay exit, which is the most likely l

point cf egress from the autoclave area, and the ACR.
l 4.3.1.1.2 Cylinder Drop and Puncture All UP. feed cylinders are moved to the autoclaves with overhead cranes. The possibility of a cylinder drop doe to crane or lifting fbaure failure is always present. The drop and subsequent puncture of a UF. feed cylinder does not present a serious safety concern because the UF. in the cylinder is in the solid state.
Cylinders are empty (except for heel quantities of UF. and/or non-volatile uranium-bearing compounds such as UO,F ) when removed from the autoclaves and no unique safety hazard is present in this operation.
On rcre occasions, a cylinder which is filled or partially filled with liquid UF. may develop a plugged valve. If this condalon should arise, the cylinder is not removed from the autoclave until it has solidified. It can then te moved to the cylinder yard. 'De feed facility overhead cranes are not appro 'ed for handling liquid cylinders. Options are being pursued to approve the C-337 A double hook crane to handle liquid cylinders.
Failure of crane cables, hooks, brakes, and controls are considered unlikely because of the routine maintenance and periodic inspections by qualified inspectors.
4.3.1.1.3 Autoclave Leakage De autoclave / gasket / isolation valve system will be tested at accident pressure. The accident pressures appear to spike to approximately 103 psia and then relax to about 85 psia for the C-360 autoclaves; the other autoclaves will reach a pressure of about 96 psia. Derefore, a test pressure of 90 psig (104.7 psia) will te used for all autoclaves.
he leakage of the ::utoclave may te measured as an air leak rate or pressure decay rate. The allowable leakage will te less than or equal to 12 standard cubic feet of air per minute or a pressure decay of less than 10 psig in one hour with the autoclave at peak accident pressure. Derivation of these leak rates is shown below.
The autoclave containment system will be tested quarterly and priot to the routine replacement of the gasket. %e time to gasket failure and the number of use cycles to failure will be recorded. De proofing of an adequately installed new gasket shall be by a pressure decay test or leak rate test. De autoclave containment system will also te tested every time a component whose performance could impact containment performance is replaced.
Allowble Leakage Rates The allowable leakage of the autoclave should be less than or equal to 12 standard cubic feet of air per minute or a pressure decay of less than 10 psig in one hour with the autoclave at peak accident pressure.

This leak rate, assuming the instantaneous dispersion within the hemispherical volume defined by the point of the leak and the exit from the facility, approximately 75 feet, limits the intake to a worker following the plant "see and flee" policy to less than 10 mg of uranium. According to the NUREG-1391, a 10 mg intake of uranium is approximately the threshold value for transient kidney damage, it is also the weekly limit for soluble uranium intake specified in 10 CFR 20. The Statement +f-Considerations for 10 CFR 76 identifies a 30 mg uranium acute intake as a level where kidney damage may tesult.
2.
Exposure Volume = 2/3 x r x (75)' = 883,575 ft' or 883,575 x 2.832E-2rri/ff 25,022 nf 3.
Intake = AveraBe Air concentration (mg/m ) x 1.2 m3/hr x Exposure ilme (minutes)/60.
8 Air Concentration - intake x 60/1.2 or 500 mg/m' 4.
This concentration is an average concentration for the workers intake, therefore the pounds of uranium leaked is equal to the concentration times the exposure volume divided by 454,000 mg/#,
- 0 leaked = 500 x 25,022/454,000 = 27.5 pound 5.
The appropriate leak rate is 27.5 pounds per, minute; this converts to a leak rate of 160 scfm.
l For a one minute exposure, the liF concentration derived in NUREG-1391 as 137 mg/m'. Four moles of IIF are formed when one mole of UF. reacts with water vapor and condensate. The 3
concentration of uranium associated with 137 mg/m of liF is:
1, 1/4 x (137/20,000) x 238,000 or 408 mg/m' 2.
The uranium release, for a one minute release that is, produces an exposure of 408 mg/m' is 408/454,000 x 25,022 - 22.4 pounds per minute.
3.
This converts to a leak rate of 132 standard cubic feet per minute at peak accl dent pressure, if the above leak rates are divided by a factor of 10 to account for dispersion model and evacuation time uncertainties, it is recommended that 12 scfm be used as the leak rate for the test at peak accident pressure. This corresponds to a pressure loss of 24 psig per hour and 12 psig per hour for the feed and sampling autoclaves respectively.
The pressure decay (in psi per hour) for a feed autoclave with a volume of 622 ft' is computed as follows:

SECTION 2.2 SPECIFIC TSRs FOR UF. FEED FACILITIES (C-333-A AND C-337-A)
V 2.2.4 GENERAL LIMITING CONDITIONS FOR OPERATION 2.2.4.13 AUTOCLAVE MANUAL ISOLATION SYSTEM 1
SURVEILLANCE REQUIREMENTS:
Surveillance Frequency SR 2.2.4.13-1 Perform functional test of the system Arumally actuation devices.
HASIS:
The autocue inanual isolation system provides the means to remotely isolate all facility autoclaves in the event of a UF. release from a line outside the autoclave containment boundary.
De system consists of two (within the feed facilities) actuation devices located in the OMR and at the cylinder yard crane bay exit (the most likely point of egress from the autoclave area), and one remotely located actuation device in the associated cascade building ACR. Actuating the system will initiate closure of all containment valves for each of the autoclaves within the affected facility. In the event of a UF. release from a line out.dde the autoclave containment boundary, the operator, while exiting the facility in accordance with the "see-and flee" policy, would actuate
(
the system to isolate the release point ftom the UF. source and limit the amount of material released. Closure of valves XV-503, CV 504, XV-505, CV-511, and C.'-510 isolate a cylinder within an autoclave from piping outside the containment boundary thereby eliminating the source of UF. available for release. [SAR Section 4.3.1.1.1) he autoclave manual isolation system closes the same containment valves as those described in TSR 2.2.3.1 for the autoclave high pressure isolation system. Therefore, the operability and surveillance requirements for these valves are included in Section 2.2.3.1. TSR surveillance 2.2.4.13-1 is not required to include the actual closure of all of the containment valves on all autoclaves simultaneously as this would require complete shutdown of the feed facility. The test will be performed by disabling the local actuation devices from the autoclaves not being tested and verifyiag the appropriate contaimnent logic output from the programmable logic controller for the autoclaves being tested. Testing of all au'.oclaves in a facility will verify operability of the manual isolation system. Containment valve closure is verified quarterly by the performance of the TSR surveillance requirement 2.2.3.1-2.
If condition D is enttred and action D.3 is selected from among the three options, the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> time limitation for completing action D.3.2 provides a limit for how long the AMIS may be out of service under Condition D.
