3.14.6.1 All fire rated assemblies (walls, floor / ceilings, cable l tray enclosures and other fire barriers) separating safety-related fire areas or separating portions of redundant sys-tems important to safe shutdown within a fire area and all sealing devices in fire rated assembly (fire doors, fire windows, fire dampers, cable, piping, and ventilation, duct penetration seals) shall be OPERABLE.

3.14.6.2 With one or more of the above required fire rated assemblies and/or sealing devices inoperable, within one hour'either establish a continuous fire watch on at least one side of the affected assembly, or verify the OPERABILITY of fire detectors on at least one side of the inoperable assembly and establish an hourly fire watch patrol. Restore the inoperable fire rated assembly and sealing device to OPERABLE within 7 days or, in lieu of any other reports re-quired by Specification 6.9, prepare and submit a Special Report to the Commission pursuant to Specification 6.9.5.E .

within the next 30 days outlining the action taken, the cause of the inoperable fire rated assembly and/or sealing device and plans and schedule for restoring the fire assembly and sealing device to OPERABLE status.

Bases OPERABILITY of all fire detection instrumentation ensures that adequate

' warning capability is available for the prompt detection of fires. This espability is required in order to detect and locate fires in their early cttgns. Prompt detection of fires will reduce the potential'for damage

to cafety-related equipment or redundant systems important to safe shut-down and is an integral element in the overall facility fire protection program. ,

7 In the event that a portion of the fire detection instrumentation is i inoparable, the establishment of frequent fire patrols in the affected crGes is required to provide detection capability until the inoperable l inOtrumentation is returned to service.

RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Limited Conditions for Operation B' son (Continued)

Tho OPERABILITY of the fire suppression systems ensures that adequate firo suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety-related equipment cr redundant systems important to safe shutdown is located. The fire cuppression system consists of the water system, spray and/or sprinklers, CO2, and fire hose stations. The collective capability of the fire cuppression systems is adequate to minimize potential damage to safety rointed equipment or redundant systems important to safe shutdown and is a major element in the facility fire protection program.

In the event that portions of the fire suppression systems are inoper-eblo, alternate backup fire fighting equipment is required to be made cynilable in the affected areas until the affected equipment can be rOctored to service.

In the event that the fire suppression water system becomes inoperable, imm diate corrective measures must be taken since this system provides tha major fire suppression capability of the plant. The requirement for n tw;nty-four (24) hour report to the Commission provides for prompt .

cvaluation of the acceptability of the corrective measures to provide ad:quate fire suppression capability for the continued protection of the nucicar plant.

ThJ operable integrity of the fire rated assemblies 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 dst:ction and extinguishment. The fire rated assemblies are a passive alcm:nt in the facility fire protection program and are subject to pariodic inspections. During periods of time when the fire rated ecs mblies are inoperable, an hourly or continuous fire watch, as cppropriate, is required to be maintained in the vicinity of the affected ccccmbly until the assembly is restored to operable status.
