Requirements for HEPA FILTER BANKS in these systems are detailed in their respective LIMITING CONDITION FOR OPERATION (LCO).

PSR-3 Rev. 3 Page 4 of 25 ACTION A HEPA filter (FILTER BANK) that has been determined not to provide a collection efficiency of at least 99.95 percent for particulates 0.3 microns in diameter and larger shall be IMMEDIATELY removed from service and shall be replaced with a HEPA filter (FILTER BANK) having the required collection efficiency.

SURVEILLANCE REQUIREMENT HEPA filters (FILTER BANKS) for the Vessel Off-Gas (VOG), and Main Plant, (identified in Table 1) shall be tested in-place ANNUALLY and after each filter change, before return to routine service, to establish that the installed filters (either individually, or collectively when in a FILTER BANK) provide a collection efficiency of at least 99.95 percent particulates 0.3 microns in diameter and larger. In-place leak tests shall be performed per an approved IMPLEMENTING PROCEDURE.

1.2 LIMITING CONDITION FOR OPERATION

a. Instrumentation (identified in Table 1) for monitoring differential pressure across the OPERATING final HEPA filter (FILTER BANK) and across the backup final HEPA filter (FILTER BANK) shall have current calibration.
b. Instrumentation (identified in Table 1) for monitoring differential pressure across the OPERATING final HEPA filter (FILTER BANK) shall be OPERATING.
c. Instrumentation (identified in Table 1) for monitoring differential pressure across the backup final HEPA filter (FILTER BANK) shall be OPERABLE.

PSR-3 Rev. 3 Page 5 of 25 ACTION

a. If any instrument (identified in Table 1) for monitoring differential pressure across the OPERATING final HEPA filter (FILTER BANK) and across the backup final HEPA filter (FILTER BANK) does not have current calibration, that instrument shall be declared INOPERABLE and IMMEDIATE efforts shall be taken to calibrate that instrument.
b. If the instrumentation monitoring differential pressure across the OPERATING final HEPA filter (FILTER BANK) should become INOPERABLE, filter operation may continue for ten days, provided that the instrumentation monitoring the differential pressure across the OPERATING FILTER TRAIN is OPERATING. If the OPERATING FILTER TRAIN differential pressure instrumentation is also INOPERABLE or unavailable, the backup FILTER TRAIN shall be placed on-line and IMMEDIATE efforts shall be taken to restore the OPERABILITY of the affected equipment. In systems not maintaining an OPERABLE backup FILTER TRAIN, operations within the facility shall be terminated within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and restart not permitted until the OPERABILITY of the affected equipment is restored.
c. If the differential pressure instrumentation associated with the backup final HEPA filter (FILTER BANK) should become INOPERABLE, IMMEDIATE efforts shall be taken to restore the OPERABILITY of the affected equipment.

SURVEILLANCE REQUIREMENTS

a. Instrumentation (identified in Table 1) for monitoring differential pressure across the OPERATING final HEPA filter (FILTER BANK) and across the backup final HEPA filter (FILTER BANK) shall be calibrated ANNUALLY per an approved IMPLEMENTING PROCEDURE.
b. Instrumentation (identified in Table 1) for monitoring the differential pressure across the OPERATING final HEPA filter (FILTER BANK) shall be monitored and the readings recorded once per SHIFT.

PSR-3 Rev. 3 Page 18 of 25 BASES

1. HEPA FILTER (FILTER BANK) GENERAL REQUIREMENTS 1.1 HEPA filters provide the primary barrier to the release of airborne contamination to the environment. A minimum mass removal efficiency has been determined for ventilation system filters to ensure that these releases are maintained As Low As Reasonably Achievable (ALARA). Filter system efficiency is determined at the WVDP through in-place leak testing new filters before operation and through subsequent annual tests.

Exceptions to the requirements in this LCO have been made for the Head End Ventilation System and the Permanent Ventilation System due to restrictions in the physical configuration of these systems which do not allow for testing of individual HEPA FILTER BANKS. Special requirements for these systems have been provided in LCOs. The Safety Analysis Report (SAR) for the FRS Facility indicates that airborne contamination levels in the facility are sufficiently low that a HEPA-filtered ventilation system is not required to maintain doses ALARA.

HEPA filters purchased for use at the WVDP are required to have been previously tested to ensure an acceptable particulate removal efficiency. Leak tests are performed on filters in-place in the system. Demonstration of acceptable HEPA filter (FILTER BANK) efficiency following filter replacement potentially requires filter adjustments. An in-place leak test is performed after each adjustment to determine that the filter has sealed adequately. Once it has been determined that the filter seal is acceptable, the filter must successfully pass subsequent in-place leak tests.

1.2 Failure of a HEPA filter could potentially result in the release of a significant amount of radioactive contamination. High differential pressure across a filter could result in filter failure and indicates that the filter needs to be changed. Low differential pressure across a filter indicates a possible filter failure. Differential pressure instrumentation has therefore been incorporated into facility ventilation systems to ensure detection of abnormal pressure conditions.

PSR-3 Rev. 3 Page 19 of 25 Instrumentation accuracy and OPERABILITY is ensured through routine calibration. OPERABILITY is also determined through routine SHIFT readings.

OPERABILITY of backup instrumentation is determined through ANNUAL calibration and readings taken during periodic testing of backup equipment.

Final HEPA filter differential pressure can be determined either directly through instrumentation dedicated to the filter or indirectly through FILTER TRAIN differential pressure instrumentation. FILTER TRAIN differential pressure instrumentation can provide a level of assurance of filter integrity; however, it is not a direct indication of final HEPA filter differential pressure and must not serve in this capacity for an extended period of time.

Because failure of final filter instrumentation does not result in a degradation of filter system integrity, use of FILTER TRAIN instrumentation to indicate differential pressure is preferred over loss of filter system redundancy due to declaring the OPERATING filter system INOPERABLE. Therefore, operation may continue for a limited time provided that FILTER TRAIN instrumentation is available and OPERATING.

Failure of both instruments reduces the ability to determine filter integrity to an unacceptable level and requires that the backup FILTER TRAIN be placed on line. It is therefore necessary to maintain instruments for the backup final HEPA filter and the backup FILTER TRAIN in a state of readiness. In systems not having a backup or having an INOPERABLE backup, operations in the ventilated facility must be halted to minimize the amount of airborne radioactive contamination generated.

1.3 FILTER TRAIN differential pressure instrumentation provides a backup to final HEPA filter differential pressure instruments. This instrumentation must therefore be OPERATING for the online FILTER TRAIN and must be OPERABLE for the offline FILTER TRAIN.

1.4 Alarms provide a prompt indication of an off-normal pressure differential occurrence and therefore must be maintained OPERABLE to minimize the consequences due to this condition.

PSR-3 Rev. 3 Page 20 of 25 1.5 Final HEPA filter low differential pressure alarm levels are dynamic to account for increased differential pressure due to particulate loading following filter installation. Selection of a limit of 3 inches W.C. below the OPERATING differential pressure once the OPERATING differential pressure has exceeded 5 inches W.C. allows for determination of a low differential pressure occurrence while minimizing false alarms. Differential pressure below the low differential pressure alarm set point indicates a possible final HEPA filter failure, possibly resulting in the release of unfiltered air to the environment. For this reason, filters having differential pressure below the low differential pressure alarm set point must be IMMEDIATELY placed off-line until filter integrity is determined.

1.6 Final HEPA filter high differential pressure alarm set point requirements have been made such that the high differential alarm will annunciate before the maximum sustained OPERATING differential pressure is achieved. This provides a sufficient amount of time for an orderly filter changeout. HEPA filters purchased for use at the WVDP have been previously tested to withstand a differential pressure of 10 inches W.C. The maximum sustained OPERATING filter differential pressure has been chosen to provide an adequate margin to safety.

Routine monitoring of filter differential pressure ensures that the OPERATING differential pressure has not exceeded this value. This is the only means of determination once the high differential pressure alarm point has been exceeded.

2. VESSEL OFF-GAS (VOG) SYSTEM 2.1 The VOG System provides ventilation for vessels associated with the Liquid Waste Treatment System (LWTS). The ventilation system and vessels are located entirely within the former reprocessing facility (main plant) in ventilated cells. This system maintains a redundant filter and blower so that failure of the OPERATING FILTER BANK or exhaust blower does not require IMMEDIATE facility shutdown. In the event of complete failure of the VOG system, off-gas can passively migrate through the VOG system preventing over-pressurization of system vessels. The main plant ventilation system is sufficient to prevent migration of any leakage contamination into routinely occupied areas. However this is not a desirable method of operation; therefore, an orderly shutdown of

PSR-3 Rev. 3 Page 21 of 25 the LWTS must be performed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Twenty-four hours permits the completion of evaporation of the contents in the evaporator thereby avoiding the need to send off-spec concentrates back to the high level waste tank.

2.2 The VOG System maintains an OPERABLE manual switchover capability to ensure that backup systems in-place can be put on-line when necessary. Failure of switchover capability does not result in a degradation of filter system integrity, therefore specific criteria have been established in the LCO for continued operation of the ventilation system without this capability.

2.3 OPERABILITY of manual switchover capability and backup equipment is routinely tested to ensure that systems will perform their functions wnen required.

3. HEAD END VENTILATION (HEV) SYSTEM 3.1 The BEV System exhausts the Process Mechanical Cell (PMC), General Purpose Cell (GPC), Chemical Process Cell (CPC) and provides ventilation support for the Contact Size Reduction Facility (CSRF). The HEV System is comprised of redundant trains consisting of a prefilter, a roughing filter, and two HEPA filters in series. Electric motors power the two identical primary blowers while the backup blower is powered independently.

The physical configuration of the HEV System precludes in-place leak testing of the final HEPA filter. It is possible only to obtain an efficiency of the roughing filter - HEPA filter - HEPA filter combination. The series of filters employed in the system are provided primarily to extend the life of the final HEPA filter rather than for particulate removal considerations. Therefore, the LCO requirement for the collection efficiency of the FILTER TRAIN is the same as that for final HEPA filters (FILTER BANKS) as set forth in LCO 1.1.

3.2 The Main Plant Ventilation System initially provided ventilation for the entire main plant building, with the HEV System added on several years after the initiation of reprocessing to improve ventilation in high airborne activity cells. Dampers in the ventilation system can be adjusted to allow the Main Plant Ventilation System to ventilate cells normally serviced by the HEV System in the event that the HEV System, including backup equipment, should become

PSR-3 Rev. 3 Page 22 of 25 INOPERABLE. It is under this reconfiguration that carefully monitored work in the plant can be performed per approved work procedures in the absence of HEV operation.

Equipment in this system is provided with a backup to ensure continuous OPERABILITY. Operations in the main plant facility may continue for ten days without an OPERABLE backup filter or exhaust blower while affected equipment is being returned to service. Ten days permits equipment repair or replacement without upsetting maintenance programs, yet entails minimal risk when conducting operations without a spare. If the system is not restored to OPERABILITY within ten days, work in the plant must be suspended unless specific requirements stated in the LCO are met. This ensures restriction of projects which may result in the generation of airborne radioactive materials.

Filter differential pressure instrumentation is monitored routinely to ensure that the system is OPERATING.

_, 3.3 The HEV System shall maintain an OPERABLE automatic switchover capability to ensure that backup systems in-place can be put on-line when necessary.

4. MAIN PLANT VENTILATION SYSTEM 4.1 The Main Plant Ventilation System exhausts air through the process areas beyond the CPC from clean areas to successively more contaminated areas. Equipment in this system is provided with a backup to ensure continuous OPERABILITY.

Operations in the main plant facility may continue for ten days without an OPERABLE main plant ventilation system backup filter or exhaust blower while affected equipment is being returned to service. Ten days permits equipment repair or replacement without upsetting maintenance programs, yet entails minimal risk when conducting operations without a spare. If the system is not restored to OPERABILITY within ten days, work in the plant must be suspended unless specific requirements stated in the LCO are met. This ensures restriction of projects which may result in the generation of airborne radioactive materials.

PSR-3 Rev. 3 Page 23 of 25 Filter differential pressure instrumentation is monitored routinely to ensure that the system is OPERATING.

4.2 The Main Plant Ventilation System shall maintain an OPERABLE automatic switchover capability to ensure that backup systems in-place can be put on-line when necessary.

5. PERMANENT VENTILATION SYSTEM (PVS) 5.1 The PVS provides the primary ventilation for both the STS building and the WTF HLW storage tanks. The physical configuration of the PVS precludes in-place leak testing of the final HEPA filter. It is possible only to obtain an efficiency of upstream HEPA filter - first stage HEPA filter - of each train and the HEPA filter train combination - first stage and second stage HEPA filter combination. The series of filters employed in the system are provided primarily to extend the life of the final HEPA filter rather than for particulate removal considerations. Therefore, the LCO requirement for the collection efficiency of the FILTER TRAIN is the same as that for final HEPA filters (FILTER BANKS) as set forth in LCO 1.1.

System OPERABILITY is determined through routine readings of final HEPA filter differential pressure instrumentation.

5.2 Equipment in this system is provided with a backup to ensure continuous OPERABILITY. Operations in the STS may continue for ten days without an OPERABLE PVS backup filter or exhaust blower while affected equipment is being returned to service. Ten days permits equipment repair or replacement without upsetting maintenance programs, yet entails minimal risk when conducting operations without a spare. If the PVS redundancy is lost while it is serving as the primary ventilation system for a HLW tank, contamination control would rely on a single operating filter train or blower. Without an OPERABLE PVS backup filter or exhaust blower operations in the HLW tanks must be terminated within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. This would minimize the potential for degradation of the remaining filter train or blower and potential loss of contamination confinement. Twenty-four hours provides sufficient time to permit an orderly shutdown of the Supernatant Treatment System or transfer operations.

PSR-3 Rev. 3 Page 24 of 25 5.3 The PVS shall maintain an OPERABLE automatic switchover capability to ensure that backup systems in-place can be put on-line when necessary.

3. LIMITING CONDITION FOR OPERATION Equipment listed in Table 3 shall be capable of being supplied with STANDBY POWER as appropriate.

PSR-5 Rev. 3 Page 5 of 9 ACTION If it is determined that STANDBY POWER is not available for a component listed in TaL 3, IMMEDIATE efforts shall be taken to restore the STANDBY POWER capability.

SURVEILLANCE REQUIREMENT The capability to supply STANDBY POWER to equipment listed in Table 3 shall be tested for OPERABILITY QUARTERLY. OPERABILITY shall be determined per an approved procedure.

4. LIMITING CONDITION FOR OPERATION The on-line blower motor in the Vessel Off-Gas System (6K-2 or 6K-2A) shall be capable of restarting following an interruption of electrical power to the blower motor.

ACTION If the restart capability of the motor for the on-line blower in the Vessel Off-Gas System (6K-2 or 6K-2A) is found to be INOPERABLE, IMMEDIATE efforts shall be taken to restore OPERABILITY.

SURVEILLANCE REQUIREMENT The capability to restart the on-line blower motor in the Vessel Off-Gas System (6K or 6K-2A) shall be tested for OPERABILITY QUARTERLY. OPERABILITY shall be determined per an approved procedure.

BASIS STANDBY POWER is provided to maintain ventilation within Hazard Category 2 facilities at the WVDP in the event of loss of normal (off-site) power. References to BACKUP POWER have been deleted from this PSR, because equipment requiring BACKUP POWER has been removed from service and replaced by equipment supplied by STANDBY POWER. For those systems which rely upon diesel fuel for operations, the associated LIMITING CONDITION FOR OPERATION specifies a minimum quantity of fuel during NORMAL OPERATIONS, i.e., during the period of time when the STANDBY POWER system is not being used since the routine power source is available. In addition, a LIMITING CONDITION FOR OPERATION is also provided which states a minimum quantity of fuel to be present during operations or following recent operations of the associated STANDBY POWER system. These quantities are based upon rate of consumption, alternative fue' supplies and operational constraints. The capability to readily restart blower motoi following a loss of off-site power is important to minimize potential hazards (e.g.,

airborne contamination).
