Catawba Nuclear Station Docket No. 50-413, -414 Selected Licensee Commitments Manual (SLC)

Gentlemen:

Pursuant to 10 CFR 50.4 and 50.71, please find attached 7 copies of the latest revision dated 5/91 to the Catawba Selected Licensee Commitments Manual. The SLC Manual is Chapt 2r 16.0 to the Catawba FSAR. This manual is meant to contain commitments and otner station issues that we believe warrent higher control, but are riot appropriate in the Technical Specifications (TS). Instead of being updated with the annual FSAR Update, the SLC Manual will be updated monthly as needed during the year.

Very truly yours, a Se UA.)& r M.S. Tuckman HAF/haf Attachment xt:

BASES:

OPERABILITY ~ of the detection instrumentation ensures that both adequate warning capability is available for prompt detection of fires and that Fire Suppression Systems, that are actuated by fire detectors, will discharge extinguishing agents in a timely manner.

Prompt detection and suppression of fires will reduce the potential for damage to_ safety-related equipment and is an integral element in the overall facility Fire Protection Program.

Fire detectors that are used to actuate Fire Suppression Systems represent a more critically important component of a plant's Fire Protection Program than detectors that are installed solely for early fire warning and notification.

Consequently, the minimum number of OPERABLE fire detectors must be greater.

The loss of detection capability for Fire Suppression Systems, actuated by fire detectors, represents a significant degradation of fire protection for any area.

As a result, the establishment of a fire watch patrol must be initiated at an earlier stage than would be warranted for the loss of detec-tors that provide only early fire warning.

The establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperab'le instrumentation is restored to OPERABILITY.
