Limiting Conditions for Operation 3.14.6 Fire Barrier Penetration Fire Seals Specification 3.14.6.1 With one or more of the above required fire barrier penetrations ncn-functional, within one hour either, establish a continuous fire watch on at least one side of the af fected penetration, or verify the OPERA-68 BILITY of fire detectors on a.t least one side of the non-functional fire barrier and establish an hourly fire watch patrol.
Bases OPERABILITY of the fire detection instrumentation ensures that adequate warning capabill*f is available for the prompt detection of fires. This capability.is requirca in order to detect and locate fires in their early stages.
Prompt de-tection of fires will reduce the potential for damage to safety related equipment cod is an in'.cgral 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 instrumentation is returned to service.
The OPERABILITY of the fire suppression systems ensures that. adequate fire suppres-slon capability is available to confine and extincuish fires occurring in any-portion of the facility where safety related equipment is located.
The fire sup-pression system consists of the water system, spray and/or sprinklers, CO, and 2
fire hose stations. The collective capability of the fire suppression systems is tdequate 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 s'; tems are inoperable, alter-nate backup fire fighting equipment is required to be made available in the affected areas until the affected equipment can be restored to service.
in the event that.the fire suppression water systen becomes inoperable. immediate corrective measures must be taken since this sys+cm provides the major fire sup-pression capability of the plant.
The requircrent for a twenty-four (24) hour
{
report to the Commission provides for prompt evaluati.. of the acceptability of the corrective measures to provide adequate fire suppression capability for the l
continued protectiqn of the nuclear plant.
i I
The functional integrity of the fire barrier penet' ration seals ensures that fires will be confined or adequately ' retarded from spreading to adjacent portions of I
the facility. This design feature minimizes the possibility of a singic fire l
rapidly involving several areas of the facility prior to detection and extinguish-ment. The fire barrier, penetration seals are a passive element in the facility fire protection program hnd are subject to periodic inspections.
