BASES 3/4.3.3.S _ FIRE DETECTION INSTRUMENTATION 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 poten-tial for damage to safety related equipment and is an integral element in the overall facility fire protection program.
In the evert 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.
3/4.7.11 FIRE SUPPRESSION SYSTEMS q
The OPERABILITY of the fire suppression systems ensures that ade-quate 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, spray and/or sprinklers, C0, Halon and fire hose stations. T!.e collectiveca9abilityofthefires$ppressionsystemsisadequateto minimize potertial 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 systeias are inoperable, alternate 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 system becomes in-operable, imediate corrective measures must be taken since this system provides the major fire suppression capability of the plant. The requirement 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 pro-tection of the nuclear plant.
