i 3/4.3.3.8 FIRE DETECTION INSTRUMENTATION OPERABILITY of the fire detection instrumentation ensures 'that adequate warriing^ capability is available for the prompt detection of, fires. This capability is required in order to detect and locate fi'res in their early stages.
Prompt detection of fires will reduce the poten-
~
tial for damage to safety related equipment and is an integral element in the ovprall facility. fire protection program._
l In the event that a portion of the fire detect ~ ion instrumentation is inoperable, the establishment of frequent fire patrols in the affected.
areas is re. quired to provide detection capability until the inoperable instrumentation is restored to OPERABILITY.
3/4.7.11 FIRE SUPPRESSION SYSTEMS The OPERABILITY of the fire suppression systems ensures that' adequate fire suppressi.on capcbility is available to confine and extingui'sh fires occuring in any portion of the facility where safety related equipment is located.. The fire suppression system consists of the water systea*,
spray and/or sprinklers, 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 portions of the fire suppression systems are inoperable, alternate backup fire fighting equipment is required.to be made available in the affected are until the inoperable equipment is restored to service.
In the event the fir'e' sup; ssien water sistem becomes inoperab1'e, f
intnediate corrective measures must be 'talten since this system provides the major fire suppression capability of the plant.
The requirement for a twenty-four hour report to the Co~ mission provides for prompt evalua-l tion o.f tha acceptability of the corrective measures to provide adecuate j
fire suppression capability for the continued protection of the nuclear i
plant.
j 3/4.7.12 PENETRATION FIRE BARRIERS i
The functional integrity of.the penetration fire barriers ' 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 penetration fire barriers are a passive element in the facility fire protection program and are subject to periodic inspections.
Y' During periods of time when the barriers are not functional, routine fire watch patrols in cenjunction with OPERABLE fire detection instrumentation or a continuous fire watch are required to be maintained in the vicinity of the affected barrier until the barrier is restored to functional status.
