UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 September 24, 1990 Docket Nos. 50-361 and 50-362 Mr. Harold B. Ray Mr. Gary D. Cotton Senior Vice President Senior Vice President Southern California Edison Co.

23 Parker Street 101 Ash Street Irvine, California 92718 San Diego, California 92112 Gentlemen:
SUBJECT:
SAFETY EVALUATION REPORT OF THE INSERVICE TESTING (IST) PROGRAM FOR PUMPS AND VALVES, SAN ONOFRE NUCLEAR GENERATING STATION, UNIT NOS. 2 AND 3 (TAC NOS. 55120 AND 55121)
The enclosed Safety Evaluation Report (SER) was prepared by the staff to provide the results of the review of the San Onofre Nuclear Generating Station, Unit Nos.
2 and 3, Inservice Testing Program for pumps and valves.
The Code of Federal Regulations, paragraph 10 CFR 50.55a(g), requires certain Class 1, 2, and 3 pumps and valves in water-cooled nuclear reactor facilities to meet the inservice testing requirements stated in the ASME Boiler and Pressure Vessel Code,Section XI; specifically, Subsection IWP,-Inservice Testing of Pumps in Nuclear Power Plants, and Subsection IWV, Inservice Testing of Valves in Nuclear Power Plants. Each facility is required to establish a program for the inservice testing of pumps and valves which is updated every ten years to meet the requirements in the latest approved edition and addenda to Section XI of the ASME Code. The program is submitted to the NRC for review and approval of the relief requests. The review entails verifying that the program is based on the applicable Code edition and addenda, verifying that the program covers testing of all appropriate pumps and valves, and verifying the acceptability of the requests for relief from the requirements of Subsections IWP and IWV.
The IST program addressed in this report covers the first ten-year interval for both Units 2 and 3 from August 18, 1983, to August 18, 1993. The licensee's program through Revision 14 for Unit 2 and Revision 9 for Unit 3, submitted in a letter dated May 18, 1990, was reviewed for this report.
The staff, with technical assistance from EG&G Idaho, Inc. (EG&G), has reviewed and evaluated the IST program and requests for relief submitted for San Onofre Nuclear Generating Station, Unit Nos. 2 and 3. The staff adopts the evaluations and conclusions contained in the Technical Evaluation Report (TER) prepared by EG&G. The enclosed SER incorporates theTER, also enclosed, and its findings.
We granted relief from the testing requirements which we have determined would be impractical to perform, where compliance would result in a hardship without a compensating increase in safety, and where th'e-proposed alternative testing provides an acceptable level of quality and safety.

9669:
Messrs. Ray and Cotton September 24, 1990 Certain relief requests have been denied or partially denied where proposed alternative testing is unacceptable or where an adequate basis for the relief request has not been provided. With the exception noted above, we have.
determined that the IST program relief requests are acceptable for imple mentation provided the omissions and inconsistencies identified in Appendix C of the TER are addressed within the timeframe specified in the SER.
You are required to comply with the IST program defined in the above referenced letter where relief has been granted in the enclosed SER. Program changes, such as, additional relief requests or changes to relief requests, should be submitted for staff review but should not be implemented prior to review and approval by the NRC. New or revised relief requests meeting the positions in Generic Letter 89-04, Enclosure 1, should be submitted to the NRC staff, but can be implemented provided the guidance in Generic Letter 89-04, Section D, is followed. Program changes that involve additions or deletions of components from the IST program should be provided to the NRC.
This submittal completes the technical review performed under TAC Nos. 55120 and 55121.
