Fire' protection Requirements

.s

Dear Sir:

My letter dated March 13, 1990 submitted a proposed amendment'to the Catawba.-

J Nuclear ~ Station Tednical Specification (TS) to relocate Fire Protection or related requirementa from TS to the Catawba FSAR while adding-the Fire Protection Program to those items included in Specification 6.5.1 and 6.8.1.

j This letter contains at revision to the FSAR-Chapt.e 16.0, Selected Licensee Commitments, which was contained in my previous submittal.

Pages 16.9-5, 4

-16.9-16ca'nd_16.9 17 of.the original submittal should be replaced-with the

.l corresponding new pagos attached to this" letter.-

New page 16.9-5 deletes reference to Catawba SER,-Supplement 5, Section 9.5.1.

This reference does not discuss the Spray and/or Sprinkler systems,

.and.therefore does.not_ apply.

New pages:16.9-16'and 16.9-17 contain the Basis for the Fire Detection Instrumentation. The original' submittal inadvertently contained the Bases for. Fire Suppression Systems in this section.

r

-The conclusien~of my. March 13, 1990 submittal remains valid. The proposed changes do.not involve significant hazards considerations.

Very truly yours,

Each of - the above required heat detection instruments shall be

' demonstrated OPERABLE as follows:

1. - For nonrestorable spot-type detectors, at least two detectors' out of every hundred, or fraction thereof, shall be removed every 5 years and functionally - tested.

For each failure that' occurs on the detectors removed, two additional detectors shall be removed and tested; and ii.

For restorable spot-type heat detectors, at least.one e+tector on each signal initiating circuit shall be demonstrated OPERABLE' at least.once per 6 months-by performance of a TRIP ACTUATING DEVICE OPERATIONAL TEST.

Different detectors shall be ' selected for each '

test.

Fire detectors which are not accessible during_- plant operation shall be demonstrated OPERABLE by the performance of a

-TRIP ~ ACTUATING DEVICE OPERATIONAL TEST-during each COLD SHUTDOWN exceeding-24 hours unless performed in the previous 6 months.

b.

The NFPA Standard 720 supervised circuits supervision associated with the 1 3 detector alarms of each of the above required fire detection instruments shall be demonstrated OPERABLE at least once per 6 months.

Catawba Fire Protection Review, as Revised 6)

' Catawba Fire Protection Commitr.ient i 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 Prctection Program than detectors that are installed solely for early fire warning and notification.

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

Th5 loss of detection capability for Fire Suppression Systems, actuated by fi tt; detectors, represents a significant degradation of fire protection for 16.9-16 e
