'f except during a refueling outage 'when the missile shield and reactor vessel both channels are inoperable, the channels shall be restored to OPERABLE status in the nearest refueling out-age. If only one channel is inoperable, it is intented that this channel restored to OPERABLE status in a refueling outage as soon as reasonably be 3/4.3. 3. 7 FIRE DETECTION INSTRUMENTATION

'OPERABILITY'of the fire detection instrumentation ensures that adequate warning capability is available for the prompt detection of fires and that fire suppression systems, that are actuated by fire detectors, will discharge extinguishing agent in a timely manner. Prompt detection and suppression of fires will reduce the potential for damage'to safety-related equipment and is an integral element in the overall facility fire protection program.

( a more Fire detectors that are used to actuate fire suppression systems represent critically important component of a plant's fire protection program than detectors that are installed solely for early fire warning and notification.

Consequently, the minimum number of operable fire detectors must be greater.

The loss of detection capability for fire suppression systems, actuated by fire detectors, represents a significant degradation of fire protection for any area. As a result, the establishment of a fire watch patrol must be initiated at an earlier stage than would be warranted for the loss of detectors that pro-vide only early fire warning. The establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is restored to OPERABILITY.

The fire zones listed in Table 3.3-11, Fire Detection Instruments, are discussed in Section 9B of the PVNGS FSAR.

3/4.3.3.8 LOOSE-PART DETECTION INSTRUMENTATION The OPERABILITY of the loose-part detection instrumentation ensures that sufficient capability is available to detect loose metallic parts in the primary system and avoid or mitigate damage to primary system components. The allowable out-of-service times and surveillance requirements are consistent with the recommendations of Regulatory Guide 1. 133, "Loose-Part Detection Program for the Primary System of Light-Water-Cooled Reactors," May 1981.

3/4.7.10 SEALED SOURCE CONTAMINATION

.,The limitations on removable contamination for sources requiring leak test-ing, including alpha emitters,,is based on 10 CFR 70.39(c) limits for plutonium.

This limitation will,,ensure that le'akage 'from byproduct, source, and special nuclear material s'ources, will.not exceed allowable intake values.

Pi w "Qwi J ah~,ilgwu Ii>l >mrs<>>r e

V

'

'ealed sources 'are classified into three groups according to their use, 4

with surveillance requirements commensurate with the probability of damage to a source in that group. Those sources which are frequently handled are required to be tested more often than those which are not. Sealed sources which are continuously enclosed, within a shielded mechanism (i. e. sealed sources within radiation monitoring or boron measuring devices) are considered to be stored arid need not be tested unless they are removed from the shield mechanism.

3/4.7. 11 FIRE SUPPRESSION SYSTEMS The OPERABILITY of the fire suppression systems ensures that adequate fire suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety-related equipment is located. The fire suppression system consists of the water system, spray and/or sprinklers, CO>, Halon, fire hose stations, and yard fire hydrants. The collective capabi 1-ity of the fire suppression systems is adequate to minimize potential damage to safety-related equipment and is a major element in the facility fire protection program.

4 II In the event that portions of the fire suppression systems are inoperable, alternate backup fire fighting equipment is required to be made available in the affected area(s) until the inoperable equipment is restored to service.

When the inoperable fire fighting equipment is intended for use as a backup means of fire suppression, a longer period of time is allowed to provide an alternate means of fire fighting than if the inoperable equipment is the primary means of fire suppression.

The surveillance requirements provide assurance that the minimum OPERABILITY requirements of the fire suppression systems are met. An allowance is made for ensuring a sufficient volume of CO>/Halon in the CO>/Halon storage tank by verifying either the weight or the level of the tank.

In the event the fire suppression water system becomes inoperable, immediate corrective measures must be taken since this system provides the major fire suppression capability of the plant. The requirement for a 24-hour report to the Commission provides for prompt evaluation of the acceptability of the corrective measures to provide adequate fire suppression capability for the continued protection of the nuclear plant.

PLANT SYSTEMS BASES 3/4.7. 12 FIRE" RATED ASSEMBLIES e

The OPERABILITY of the fire barriers and barrier penetrations ensure that fire damage will be limited. These design features minimize the possibility of a single fire involving more than one fire area prior to detection and extinguishment. The fire barriers, fire barrier penetrations for conduits, cable trays and piping, fire dampers, and fire doors are periodically inspected and functionally tested to verif 'PERABILITY.

3/4.7. 13 SHUTDOWN COOLING SYSTEM The OPERABILITY of two 'separate and independent shutdown cooling sub-systems ensures that the capability of initiating shutdown cooling in the event of an accident exists even assuming the most limiting single failure occurs. The safety analysis assumes that shutdown cooling can be initiated when conditions permit.

The limits of operation with one shutdown cooling inoperable for any reason minimize the time exposure of the plant to an accident event occurring concurrent with the failure of a component on the other shutdown cooling subsystem.

3/4.7. 14 CONTROL ROOM AIR TEMPERATURE Maintaining the control room air temperature less than or equal to 80'F ensures that (1) the ambient air temperature does not exceed the allowable air temperature for continuous duty rating for the equipment and instrumentation in the control room and (2) the control room will remain habitable for opera-tions personnel during plant operation. The 30 days to return the control room air temperature to less than or equal to 80'F in the Action Statement is con-sistent with the equipment qualification program for the control room.

INSTRUMENTATION BASES

/4. 3. 3. 7 FIRE DETECTION INSTRUMENTATION E

(gQ~~ + ~ ll' g /

OPERABILITY of the fire detection instrumentation ensures that adequate warning capability is available for the prompt detection'of fires and that fire suppression systems,- that are actuated by fire detectors, will discharge

-extinguishing agent in a timely manner. Prompt detection and suppression of fires will reduce the potential for damage to safety-related equipment and is an integral element in the overall facility fire protection program.

Fire detectors that are used to actuate fire'uppression systems represent a more critically important component of a plant's fire protection program than detectors that are installed solely for early fire warning and notification.

Consequently, the minimum number of operable fire detectors must be greater.

The loss of detection capability for fire suppression systems, actuated by fire detectors, represents a significant degradation of fire protection for any area. As a result, the establishment of a fire watch patrol must be initiated an earlier stage than would be warranted for the loss of detectors that pro-

't vide only early fire warning. The establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is restored to OPERABILITY.

The fire zones listed in Table 3.3-11, Fire Detection Instruments, are discussed in Section 9B of the PVNGS FSAR.

3/4.3.3.8 LOOSE-PART DETECTION INSTRUMENTATION The OPERABILITY of the loose-part detection instrumentation ensures that sufficient capability is available to detect loose metallic parts in the primary system and avoid or mitigate damage to primary system components. The allowable out-of-service times and surveillance requirements are consistent with the recommendations of Regulatory Guide 1.133, "Loose-Part Detection Program for the Primary System of Light-Mater-Cooled Reactors," May 1981.

3/4. 3.3. 9 RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION The radioactive gaseous effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous'effluents during actual or potential releases of gaseous effluents. The alarm/trip set-points for these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the ODCM to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20. This instrumentation also includes provisions for monitoring (and controlling) the concentrations of potentially explosive gas mixtures in the GASEOUS RADMASTE SYSTEM. The OPERA-BILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50.

There are two separate radioactive gaseous effluent monitoring systems:

PLANT SYSTEMS BASES 3/4.7. 10 SEALED SOURCE CONTAMINATION

'-<..'The limitations on removable contamination for sources requiring leak test-ing, including alpha emitters, is based on 10 CFR 70.39(c) limits for plutonium.

This limitation will ensure that leakage from byproduct, source, and special nuclear material sources will not exceed allowable intake values.

'b9~394 .;"'t ) >0'i:5'f'M "'

", ."- ~ "'f'<

Sealed sources are classified into three groups according to their use, with surveillance requirements commensurate with the probability of damage to a source in that group. Those sources which are i.requently handled are required to be tested more often than those which are not. Sealed sources which are continuously enclosed within a shielded mechanism (i.e. sealed sources within radiation monitoring or boron measuring devices) are considered to be stored and need not be tested unless they are removed from the shield mechanism.

3/4.7.I1 FIRE SUPPRESSION SYSTEMS The OPERABILITY of the fire suppression systems ensures that adequate fire suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety-related equipment is located. The fire suppression system consists of the water system, spray and/or sprinklers, CO>, Halon, fire hose stations, and yard fire. hydrants. The collective capabil-ity of the fire suppression systems is adequate to minimize potential damage to safety-related equipment and is a major element in the facility fire protection program.

(

"In the event that portions of the fire suppression systems are inoperable, alternate backup fire fighting equipment is required to be made available in the affected area(s) until the inoperable equipment is restored to service.

When the inoperable fire fighting equipment is intended for use as a backup means of fire suppression, a longer period of time is allowed to provide an alternate means of fire fighting than if the inoperable equipment is the primary means of fire suppression.

The surveillance requirements provide assurance that the minimum OPERABILITY requirements of the fire suppression systems are met. An allowance is made for ensuring a sufficient volume of CO>/Halon in the CO>/Halon storage tank by verifying either the weight or the level of the tank.

In the event the fire suppression water system becomes inoperable, immediate corrective measures must be taken since this system provides the major fire suppression capability of the plant. 'the requirement for a 24-hour report to the Commission provides for prompt evaluation of the acceptability of the corrective measures to provide adequate fire suppression capability for the continued protection of the nuclear plant.

PLANT SYSTEMS BASES 3/4.7. 12 FIRE"RATED ASSEMBLIES The OPERABILITY of the fire barriers and barrier penetrations ensure that fire damage will be limited. These design features minimize the possibility of a single fire involving more than one fire area prior to detection and extinguishment. The fire barriers, fire barrier penetrations for conduits, cable trays and piping, fire dampers, and fire doors are periodically inspected and functionally tested to verify their OPERABILITY.

3/4.7. 13 SHUTOOWN COOLING SYSTEM

'I The OPERABILITY of two separate and independent shutdown cooling sub-systems ensures that the capability of initiating shutdown cooling in the event of an accident exists even assuming the most limiting single failure occurs. The safety analysis assumes that shutdown cooling can be initiated when conditions permit.

The limits of operation with one shutdown cooling inoperable for any reason minimize the time exposure of the plant to an accident event occurring concurrent with the failure of a component on the other shutdown cooling subsystem.

P 3/4.7.14 CONTROL ROOM AIR TEMPERATURE Maintaining the control room air temperature less than or equal to 80'F ensures that (1) the ambient air temperature does not exceed the allowable air temperature for continuous duty rating for the equipment and instrumentation in the control room and (2) the control room will remain habitable for opera-tions personnel during plant operation. 'he 30 days to return the control room air temperature to less than or equal to 80'F in the Action Statement is con-sistent with the equipment qualification program for the control room.
