TRANSMITTAL OF SAFETY/RELIEF VALVE (S/RV) OPERABILITY TEST REPORT FOR SUPPLY SYSTEM NUCLEAR PROJECT NO. 2

References:

1) Letter, T. Dente (BWR Owner's Group) to D.G. Eisenhut (NRC), "Transmittal of Valve Operability Test Report from Generic BWR Safety/

Relief Valve (S/RV) Test Program", dated September 25, 1981

2) Letter, G.D. Bouchey (WNP-2) to D,G, Eisenhut (NRC), "Supply System Nuclear Project No. 2 Preliminary Safety/Relief Valve (S/RV) Opera-bility Test Results", dated July 21, 1981 In response to NUREG 0737 Item II.D.l, this letter provides the final test results which demonstrate the operational adequacy of the S/RV's for WNP-2.

In addition, the adequacy of the S/RV discharge piping and supports has also been demonstrated. These final test results are contained in NEDE-24988-P, "Analysis of Generic BWR Safety/Relief Valve Operability Test Results", which was submitted to the NRC via Reference 1. WNP-2 is a participant in the BWR Owner's Group generic S/RV operability test program, WNP-2 employs the Crosby type of S/RV, The applicability of the generic test results to this plant's S/RV's has already been demonstrated in Re-ference 2. It should be noted that Reference 2 incorrectly stated that the tested Crosby 6210 Valve applicable to WNP-2 was Model No,, HB-65-.DF, The valve employed by WNP-2 is HB-65-BP.

Mr. D. G. Eisenhut October 27, 1981 Page Two G02-81-421 A review of the test report shows that the operational adequacy of the S/RV's and the piping and supports for WNP-2 has been demonstrated for the conditions defined in Item II.D.1. The submittal of NEDE-24988-P and this letter satisfies the October, 1981 and January, 1982 submittal requirements of Item II.D.l and completes WNP-2 efforts on this item.
