~'NSTRUMENTATION BASES 3/4.3.3.7 FIRE DETECTION INSTRUMENTATION SYSTEMS DETECTORS OPERABILITY of the fire detection systems/detectors ensures that adequate detection capability is available for the prompt detection of fires.This capability is required in order to detect and locate fires in their early stages.Prompt detection of the fires will reduce the potential for damage to safety related systems or components in the areas of the specified systems and is an integral element in the overall facility fire protection program.In the event that a portion of the fire detection system is inoperable, Actions a through e maintain the facility's fire protection program and allows for continued operation of the facility until the inoperable system(s)/detector(s) are restored to OPERABILITY.

However, it is not our intent to rely upon the compensatory action for an extended period of time and action will be taken to restore the minimum number of detectors to OPERABLE status within a reasonable period.In some cases, the local wet type fire suppression system, or preaction sprinkler system actuation/supervisory air (pneumatic detection system)is used as an alternative to the fire detection system in lieu of a fire watch.In these cases, the wet type suppression or the preaction actuation/supervisory air will serve as the early warning detection of a fire and alert the appropriate Control Room of a problem in the area.For those areas with cross-zone fire detection, the remaining operable fire detection string will serve as adequate fire detection in lieu of a fire watch until the inoperable fire detection string can be returned to service.3/4.3.3.8 POST-ACCIDENT INSTRUMENTATION The OPERABILITY of the post-accident instrumentation ensures that sufficient information is available on selected plant parameters to monitor and assess these variables during and following an accident.The containment water level and containment sump level transmitters will be modified or replaced and OPERABLE by the end of the refueling outage to begin in February 1989.Amendment 112 (Effective before startup following refueling outage currently scheduled in 2/89.)COOK NUCLEAR PLANT-UNIT 1 B 3/4 3-4 AMENDMENT NO.

1" fo iJ gkt1~4 BASES 3 4.7.9 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 systems consists of the water system, spray and/or sprinklers, C02, Halon, and fire hose stations.The collective capability 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 one or more C02 Suppression System requiring automatic actuation must be isolated for personal protection to permit entry for routine tours, maintenance, construction, or surveillance testing in the protected area, the fire detection system(s)required to be operable by Specification 3.3.3.7 shall be verified to be operable.Isolation of an automatic C02 suppression system temporarily puts this system in a manual actuation mode.Reliance on the fire detection system, in conjunction with the ability to manually discharge the C02 suppression system will provide adequate fire protection for periods when personnel are required to work in these areas.In the event that portions of the fire protection systems are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas 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.

Backup fire protection equipment will normally take the form of permanently mounted fire extinguishers and/or fire hose stations in or near the area, or fire hoses routed to the affected area.However, it is not our intent to rely on backup systems or other compensatory measures for an extended period of time and action will be taken to restore the inoperable portions of the fire suppression system to OPERABLE status within a reasonable period.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 Halon and C02 in the storage tanks by verifying either the weight, level, or pressure of the tanks.In the event the fire suppression water becomes inoperable, corrective measures must be taken since this system provides the major fire suppression capability of the plant.The corrective measures, including verification of fire detection operability, or roving fire watches, or alternate/backup suppression equipment, or systems, shall provide adequate fire suppression capability for the continued protection of the nuclear plant.COOK NUCLEAR PLANT-UNIT 1 B 3/4 7-7 AMENDMENT NO.

P ti'.4 (4'1 ,(t V (y1 r I I (+lpga A ts BASES~34.7.9 Con't The purpose of the charcoal filter fire suppression Technical Specification is to account for detection and suppression of fires in the charcoal filters.Manual operation of these systems is allowed because two-point heat detection with control room and local annunciation of trouble conditions is provided for the charcoal filters.The OPERABILITY of the fire suppression system protecting the charcoal filters is only required when there is charcoal in the filt'ers and the filters are required to be.operable.Actuation of spray water onto the charcoal filters requires both the manual opening of the system isolation valve and reaching the high temperature alarm setpoint for the automatic opening of the system deluge valve.Because of the inaccessibility of the lower containment to personnel during operation due to ALARA radiation exposure concerns, the use of one or more CCTVs in the lower containment to monitor for fire and smoke is an acceptable substitute to an hourly fire watch, if the fire suppression system becomes inoperable.

All hourly fire watch patrols are performed at intervals of sixty minutes with a margin of fifteen minutes.A continuous fire watch requires that a trained individual be in the specified area at all times and that each fire zone within the specified area be patrolled at least once every fifteen minutes with a margin of five minutes.A control valve is defined as a valve that when closed does not leave an alternate open flow path to a system.A sectionalizing valve is defined as a valve that when closed does not prevent an alternate open flow path to a system and hence does not make the fire suppression water system inoperable.

Under certain situations, the closure of a sectionalizing valve followed by the closure of a second valve will not leave an open flow path to one of the specified systems.In this instance, Action Statement b of Specification 3.7.9.1 is applicable.

Manual actuation of C02 fire suppression systems provides adequate fire protection for the protected areas based on operable fire detection in the area, low combustible loadings, and prompt fire brigade response to alarms.Many of the action statements take credit for operable fire detection in lieu of a fire watch when a fire protection system is inoperable.

Operable fire detection provides sufficient early warning capability of a fire to the appropriate Control Room.3 4.7.10 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 COOK NUCLEAR PLANT-UNIT 1 B 3/4 7-8 AMENDMENT NO.

I 1$p f;: p',5 Wg J f,q A4 PLANT SYSTEMS BASES The service life of a snubber is evaluated via manufacturer's input and information through consideration of the snubber service conditions and associated installation and maintenance records (newly installed snubber, seal replaced, spring replaced, in high radiation area, in high temperature area, etc...).The requirement to monitor the snubber service life is included to ensure that the snubbers periodically undergo a performance evaluation in view of their age and operating conditions.

These records will provide statistical bases for future consideration of snubber service life.The requirements for the maintenance of records and the snubber service life review are not intended to affect plant operation.

The number of snubbers to be functionally tested during each surveillance is based on calculations performed to allow extension of the surveillance interval from 18 months to 24 months, and therefore, the number of snubbers functionally tested deviates from the number required by the Westinghouse Standard Technical Specifications (NUREG-0452, Revision 4).3 4.7.8 SEALED SOURCE CONTAMINATION The limitations on removable contamination for sources requiring leak testing, 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.3 4.7.9 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 systems consists of the water system, spray and/or sprinklers, C02, Halon, and fire hose stations.The collective capability 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 one or more C02 Suppression System requiring automatic actuation must be isolated for personal protection to permit entry for routine tours, maintenance, construction, or surveillance testing in the protected area, the fire detection system(s)required to be operable by Specification 3.3.3.7 shall be verified to be operable.Isolation of an automatic C02 suppression system temporarily puts this system in a manual actuation mode.Reliance on the fire detection system, in conjunction with the ability to manually discharge the C02 suppression system will provide adequate fire protection for periods when personnel are required to work in these areas.COOK NUCLEAR PLANT-UNIT 2 B 3/4 7-6 AMENDMENT NO.

C E 7 al', I,L BASES~34 7.9.Con'In the event.that portions of the fire protection systems are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas 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.

Backup fire protection equipment will normally take the form of permanently mounted fire extinguishers and/or fire hose stations in or near the area, or fire hoses routed to the affected area.However, it is not our intent to rely on backup systems or other compensatory measures for an extended period of time and action will be taken to restore the inoperable portions of the fire suppression system to OPERABLE status within a reasonable period.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 Halon and C02 in the storage tanks by verifying either the weight, level, or pressure of the tanks.In the event the fire suppression water becomes inoperable, corrective measures must be taken since this system provides the major fire suppression capability of the plant.The corrective measures, including verification of fire detection operability, or roving fire watches, or alternate/backup suppression equipment, or systems, shall provide adequate fire suppression capability for the continued protection of the nuclear plant.The purpose of the charcoal filter fire suppression Technical Specification is to account for detection and suppression of fires in the charcoal filters.Manual operation of these systems is allowed because two-point heat detection with control room and local annunciation of trouble conditions is provided for the charcoal filters.The OPERABILITY of the fire suppression system protecting the charcoal filters is only required when there is charcoal in the filters and the filters are required to be operable.Actuation of spray water onto the charcoal filters requires both the manual opening of the system isolation valve and reaching the high temperature alarm setpoint for the automatic opening of the system deluge valve.Because of the inaccessibility of the lower containment to personnel during operation due to ALARA radiation exposure concerns, the use of one or more CCTVs in the lower containment to monitor for fire and smoke is an acceptable substitute to an hourly fire watch, if the fire suppression system becomes inoperable.

4d:~I~1 II 4c, 5 If Eg BASES~34.7.9 Con'e All hourly fire watch patrols are performed at intervals of sixty minutes with a margin of fifteen minutes.A continuous fire watch requires that a trained individual be in the specified area at all times and that each fire zone within the specified area be patrolled at least once every fifteen minutes with a margin of five minutes.A control valve is defined as a valve that when closed does not leave an alternate open flow path to a system.A sectionalizing valve is defined as a valve that when closed does not prevent an alternate open flow path to a system and hence does not make the fire suppression water system inoperable.

Under certain situations, the closure of a sectionalizing valve followed by the closure of a second valve will not leave an open flow path to one of the specified systems.In this instance, Action Statement b of Specification 3.7.9.1 is applicable.

Manual actuation of C02 fire suppression systems provides adequate fire, protection for the protected areas based on operable fire detection in the area, low combustible loadings, and prompt fire brigade response to alarms.Many of the action statements take credit for operable fire detection in lieu of a fire watch when a fire protection system is inoperable.

Operable fire detection provides sufficient early warning capability of a fire to the appropriate Control Room.3 4.7.10 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 and fire barrier penetrations for sealing devices are periodically inspected to verify their OPERABILITY.

The functional testing of the fire dampers is provided to ensure that the dampers remain functional.

The ventilation seals area seals around ventilation duct work penetrating fire barriers.It is not our intent to rely on backup systems or other compensatory measures for an extended period of time and action will be taken to restore the inoperable portions of the fire rated assembly to OPERABLE status within a reasonable period.For the purpose of determining OPERABILITY, an OPERABLE fire rated assembly and/or sealing device is one that is capable of performing its intended safety function.COOK NUCLEAR PLANT-UNIT 2 B 3/4 7-8 AMENDMENT NO.'
