PRELIMINARY SAFETY / RELIEF VALVE (S/RV) OPERABILITY TEST RESULTS fur SHOREHAM NUCLEAR POWER STATION

" Responses to NRC Questions on the BWR S/RV Test Program" dated March 31, 1981 (Response to NRC Question No. 1)

Dear Mr. Denton:

In response to NUREG-0737, Item II.D.2, this letter prevides the results of a preliminary review of the generic BWR S/RV test p.ogram results (Reference 1) in order to confirm the adequacy of the S/RV's for Shoreham Station for the alternate shutdown cooling condition which is the only expected condition resulting in liquid or two-phase discharge through the S/RV's.

The Shorenam Station employs the Target-Rock 2-stage, 6R10 type of S/RV, Model No. 7567F. The test results for the Target-Rock, 2-stage, 6R13 Valve, Model No. 7567F000 are applicable to this plant's valves (Reference 2). A preliminary review of the generic BWR S/RV test program results demorstrates that the tested valve satisfies the acceptance criteria for operability.

Consequently, based on this preliminary review, the operational adequacy of the S/RV's for the Shoreham Station has been demonstrated.

. The operability of the S/RV's for steam dischar ge conditions is demonstrated by normal vendor productior testing of each of the in-plant S/RV's.

Please contact Mr. J. P. Morin if you have an3 questions concerning this transmittal.

Very truly yours,
