. 3.22 FIRE PROTECTION SYSTEM .

3.22.1 FIRE DETECTION INSTRUMENTATION LIMITING CONDITIONS FOR OPERATION 3.22.1.1 The minimum fire detection instrumentation for each fire detection zone shown in Table 3.22.1 shall be OPERABLE~

APPLICABILITY: At all times when equipment in that fire detection zone is required to be OPERABLE.

ACTION:

With the number.of instruments OPERABLE less than required by Table 3.22.1.

1. Except the detectors located inside containment, restore the inoperable detectors to operable status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, or within the next hour, establish a fire watch patrol to inspect the zone with the inoperable instrument(s) at least once per hour.
2. For detectors located inside containment, restore the inoperable detector(s) to operable status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, or within the next hour, at least once per hour, view with the TV camera the zone containing the inoperable detector or view the zone located above.

the detector.

If a fire in containment is confirmed, be in at least hot standby within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in cold shutdown within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

3. The provision of Specifications 3.0.3 and 3.0.4 are not applicable.

BASIS OPERABILITY of the fire detection instrumentation ensures that adequate warning 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 fires will reduce the potential for damage to safety-related equipment and is an integral element in the overall facility

.fire protection program.

In the event that a portion of the fire detection instrumentation is

'inoperable, the establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumenta-tion is returned to service. None of the Fire Detection Instruments required to be OPERABLE by Table 3.22.1 actuate fire suppression systems.

Inside containment, the only combustible is cable insulation which emits a thick black smoke as a product of its combustion. Therefore surveillance by TV camera can be used to confirm a fire in any zone where detectors are irioperable.

3.22 FIRE PROTECTION SYSTEM 3.22.2 FIRE SUPPRESSION WATER SYSTEM LIMITING CONDITIONS FOR OPERATION Basis 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, sprinklers, and fire hose stations. *The collective capability of the fire suppression system is adequate to minimize potential damage to safety-related equipment and is a major elem~nt 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 areas until the inoperable equipment is restored to service.

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.

In the event of a fire in the Screen House Room, a fire is postulated to render the service water pumps, *the north diesel fire pump, and.the electric fire pump inoperable; or, to render the south diesel fire pump inoperable.

The radiant heat shield located on the north and east sides of the south diesel fire pump will prevent a fire from causing both diesel fire pumps to become inoperable.

In the event that a portion of the fire detection instrumentation is inoperable, the establishment of frequent fire patrols in the affected areas

.is required to provide detection capability until the inoperable instrumentation is restored to OPERABILITY.

Those hose stations that are supplied by the service water system in the containment will be primarily used during normal refueling operations.

* 3.22 3.22.5 FIRE PROTECTION SYSTEM FIRE RATED AND FIRE PROTECTION ASSEMBLIES LIMITING CONDITIONS FOR OPERATION 3.22.5.1.All fire rated assemblies (walls, floors, ceilings, cable tray enclosed, cable wraps), fire protection assemblies (radiant heat shields) and sealing devices in fire rated as*sembly penetrations (fire doors, fire dampers, cable, piping, and ventilation duct penetration seals) which protect safety related fire areas or separate portions of redundant sy~_tems important to safe shutdown within a fire area, shall be OPERABLE.

APPLICABILITY: Whenever the equipment protected by the fire rated assembly(ies) must be OPERABLE.

ACTION:

1. With one or more of the*above required fire rated assemblies or penetration sealing devices inoperable, ? continuous fire watch shall be established on at least one side of the affected assembly within one hour, or verify. the OPERABILITY of fire detectors on at least one side of the inoperable assembly and establish an hourly fire inspection.
2. With a fire protection assembly located outside containment rendered inoperable, within one hour establish an hourly fire inspection in that area.
3. With a fire protection assembly located inside containment rendered inoperable, restore the assembly to operable status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or be in at least hot standby within the next six (6) hours or be in at least cold shutdown within the subsequent 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.
4. The provisions of Technical Specifications 3.03 and 3.04 are not applicable.

Basis The functional integrity of the fire rated assemblies, penetration sealing devices and fire protection assemblies ensures that fires will be confined or adequately retarded from spreading to adjacent portions of the facility.

These design features minimize the possibility of a single fire rapidly involving several areas of the facility prior to detection-and extinguishment.

The fire rated assemblies, fire protection assemblies and penetration sealing devices are passive elements in the facility fire protection program and are subject to periodic inspections.
