-12 BASES The OPERABILITY of the fire suppression systems ensures that adequate fire suppression capability is available to confine and extinguish fires occuring 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, Halon, 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 fire protection measures are required to be made available in the affected areas until the inoperable equipment is restored to service. In the event 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 fire brigade backup fire suppression operability consists of a minimum of 1000 feet of 2-1/2 inch diameter (or larger) and 200 feet of 1-1/2 inch diameter (or larger) fire hose carried between site fire engines.

The surveillance requirements provide assurance that the minimum OPERABILITY requirements of the fire suppression systems are met.

The 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 potential for damage to safety-related equipment and is an integral 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 restored to operability.

The OPERABILITY of the fire barriers and barrier penetration seals ensures that fire damage will be limited.

These design features minimize the possibility of a single fire involving more than one fire area prior to detection and extinguishment. The fire barriers, fire barrier penetration seals for conduits, cable trays and piping, fire dampers, and fire doors are periodically inspected to verify their OPERABILITY.

In the event a fire rated assembly is determined inoperable, the establishment of a continuous Fire watch or a hourly Fire watch patrol with operable Fire detection on one side of the assembly is required. The usage a hourly patrol with automatic fire suppression system is acceptable, when the automatic suppression system provides adequate protection for the inoperable fire rated assembly.

Accessible fire areas as identified in the action statements of the LCO's are defined as areas that do not pose radiation and/or life-threatening safety hazards which are of a temporary nature. The areas which pose a radiation and/or life-threatening safety hazards of a permanent nature (e.g., containment) include alternate actions which would protect personnel from those hazards.
