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, CO, Halon, and fire hose stations.
The collective capability 2
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 inopera-ble, alternate backup fire fighting equipment is required to be made available in the affected areas until the affected equipment can be restored to service, c

4 3.14.6.2 Continued In the event that 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 requirements for a twenty-four 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.
-3.14.7 Fire Barrier Penetration Fire Seals 3.14.7.1 All penetration fire barriers protecting safety related areas shall be functional when equipment in those areas are required to be operable.
3.14.7.2 With the penetration fire barrier non-functional:
I a.
The operability of the fire detection systems providing coverage for the fire areas on either side of the penetration, as appli-cable, shall be verified within one hour.
b.
If either of the detection systems are inoperable, a continuous fire watch shall be established on at least one side of the af-fected penetration within one hour, c.
If either the actions of a. or b. above are not completed within the required time, prepare and submit a thirty-day written report pursuant to 6.9.2.b.
Basis:
The functional integrity of the fire barrier penetration seals ensures that fires will be confined or adequately retarded from spreadiag to adjacent portions of the f acility.
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, 3rification of fire detection system operability is required to insure that prompt detection capability exists in the vicinity of the penetration barrier.
Should an area detection system be inoperable, the fire watch will j
provide the required protection until the seal is restcred to functional status.
