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 schedulu 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 capability is required in order to detect and locate fires in their early etogrs. Prompt detection of fires will reduce the potential for damage tu ecfety-related equipment or redundant systems important to safe shut-down and is an integral element in the overall facility fire protection program.

In the event that a portion of the fire detection instrumentation is intperable, the establishment of frequent fire patrols in the affected crocs is required to provide detection capability until the inoperable instrumentation is returned to service.

. portions of the facility. This design feature minimizes the possibility of a' single fire rapidly involving several areas of the facility prior to datoction and extinguishment. The fire rated assemblies are a passive alcment in the facility fire protection program and are subject to l periodic inspections. During periods of time when the fire rated esssmblies are' inoperable, an hourly or continuous fire watch, as appropriate, is required to be' maintained in the vicinity of the affected ess:mbly.until the assembly is restored to operabic status.
