.15 FIRE PROTECTION 3.15.1 FIRE PROTECTION INSTRDIENTATICS Applicability: At all times when equipment in that fire detectior. zone is required to be operable. Fire detection instruments located within the Reactor Building are not required to be operable during the performance cf Type A Containment Leakage Rate Test.

Objective: To insure adequate fire detection capability.

Specification:

i 3.18.1.1 The minimum fire detection instrumentation for each fire detection zone shown in Table 3.18-1 shall be operable or action shall be taken as described in specificatior. 3.18.1.2.

l 3.18.1.2 With the number of OPERABLE fire detection instruments less than required by Table 3.18-1.

a. Within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, establish a fire watch patrol to inspect the zone with the inoperable instrument (s) at least once

^

per hour unless the instrument (s) is located inside the containment, then inspect the containment at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> or monitor containment air temperature at least once per hour at the locations listed in Specification 3.17.3.

b. Restore the inoperable instrument (s) to OPERABLE status within 14 days or,in lieu of any other report required by specification 6.9.2, prepare and submit a special report to the Commission within the next 30 days outlining the actions taken, the cause of the inoperability and the plans and schedules for restoring the instrument (s) to OPERABLE status.

Bases 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 eler;nt in the overall facility i 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 instrumentation is restored to operability.

3.1E.7 FIRE BARP,IER PENETRATIO::5 i Applicab ilit:, : All fire barrier penetration seals (including cable and pipe penetration barriers, fire doors and fire dampers) in fire zone boundaries protecting safety related areas shall be functional at all times when equipment on either side of the j barrier is required to be operable.

Objective: To assure the effectiveness of fire barriers.

j Specification:

3.18.7.1 All fire barrier penetration seals protecting safety related areas shall be functional or action shall be taken as described

, it 3.18.7.2.

3.16.7.2a. With one or more of the above required fire barrier penetration

' seals non-functional, establish a fire patrol to inspect at least one side of the affected penetration once per hour during refueling shutdown, cold shutdown, heatup/cooldown, and hot shutdown. At all other times a continuous fire watch shall be posted on one side of tha affected penetration within one hour.

3.18.7.2b. Restore the penetration seal to an OPERABLE status with 14 days or, in lieu of any other report required by Specification 6.9.2, prepare and submit a Special Report to the Commission within the next 30 days outlining the action to be taken, the cause of the inoperability and the plans and schedule for restarting

the system to an OPERABLE status.

Bases: The functional integrity of the fire barrier penetration seals ensures that fires will be confined or adequately retarded from spreading to adjacent portions of the facility. This design feature minimizes the possibility of a single fire rapidly involving several areas of the facility prior to detection and extinguishment. The fire barrier penetration seals are a passive element in the facility fire protection program and are subject to periodic inspections.

During periods of time when the seals are not functional, a roving or continuous fire watch is required to be maintained

in the vicinity of the affected seal until the seal is restored

' to functional status as described in specifcation 3.18.7.2.
