1 3.14-3.19/4.14-4.19 BASES 3.14/4.14 FIRE DETECTION INSTRUMENTATION OPERABILITY of the fire detection instrumentation ensures that adequate warning capability is available for the prompt detection of fires. This cap-ability is required in order to detecc 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 element in the overall facility fire protection program.

In the event that a portien of the fire detection instrumentation is in-operable, the establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is returned to service.

3.15-3.18/4.15-4.18 FIRE SUPPRESSION SYSTEMS THE OPERASILITY of the fire suppression systems ensures that adequate fire suppression capability is available to confine and extinguish fires occur.ing 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, CO 2' Halen 1301, and fire hose stations. The collective capability of the fire .

suppression syste=s is adequate to minimize potential damage to safety related equipment and is a major element in the facility fire protection program. The Halon Fire Suppression System consists of two storage tanks, each exceeding the design capacity required for extinguishment of a fire in the service water pump room in accordance with the National Fire Protection Association Standards.

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 areas until the affected equipment can be restored to service.

In the event the fire suppression water system becomes inoperable, im-eediate corrective measures must be taken since this system provides the major fire suppression capability of the plant. The require =ent for 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.

3.19/4.19 FIRE AREA BARRIERS AND PENETRATION SEALS The functional intekrity of the fire area 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 extinguish-ment. The fire area barrier penetration seals are a passive element in the facility fire protection program and are subject to periodic inspections. l During periods of time when the seals are not functional, a continuous fire watch is required to be maintained in the vicinity of the af f ected seal, or an hourly fire watch patrol can be established once the operability of a fire detector on at least one side of the affected fire barrier has been verified. A vacch or patrol will be maintained until the seal is restored to functional status.

3.19/4.19 FIRE AREA BARRIERS AND PENETRATION SEALS Fire area barriers are those components of construction which establish the boundaries of the fire areas described in the CNS. Fire Hazards Analysis (current revision). They consist of walls, floors, and' supports'(Beams, joists, columns)'1 ,

penetration seals or closures, fire doors, and fire dampers that are rated by approving laboratories or by other means in hours of resistance to fire and are used to prevent the spread of fire. Also subject to the operability and surveillance requirements are those fire barriers that separate portions of redundant safe shutdown systems'within a fire area. The specific fire barriers which were installed to separate portions of redundant safe shutdown systems within a fire area are identified as exemptions to' 10CFR50 Appendix R in the "CNS Response to 10CFR50 Appendix R ' Fire Protection of Safe Shutdown Capability'."

Fire area barrier penetration seals include cable penetration barriers, fire doors, and fire da=pers.
