UNITED STATES NUCLEAR REGULATORY COMMISSION Ir WASHINGTON, D.C. 20555-0001 May 3, 1996 Mr. J. W. Hampton Vice President, Oconee Site Duke Power Company P.O. Box 1439 Seneca, SC 29679
SUBJECT:
OCONEE NUCLEAR STATION, UNIT 1 - THIRD TEN-YEAR INTERVAL INSERVICE INSPECTION REQUEST FOR RELIEF NO. 95-04 (TAC NOS. M93944, M93945, AND M93946)
Dear Mr. Hampton:
By letter dated October 5, 1995, you submitted Request for Relief No. 95-04 from certain ASME Code requirements that you determined to be impractical to perform at Oconee Nuclear Station, Units 1, 2, and 3, during the third 10-year interval inservice inspection. Supplemental information was provided in your submittal dated February 27, 1996. Relief was requested from the requirements of Section XI of the ASME Code to perform a volumetric examination of greater than 90 percent of the weld area for the specific welds covered by this request. Performance of the Code-required examination coverage is precluded by component interfaces. To meet the Code requirements, extensive design modifications would be necessary to provide access for examination. We note that in the case of Oconee Units 1 and 2, the percent of coverage obtainable for the subject welds was estimated based on examinations performed on equivalent Oconee Unit 3 components. If the actual examination coverage for Units 1 and 2 is less than this estimate, you must submit a new request for relief based on the actual coverage obtained.
The NRC staff, with technical assistance from its contractor, the Idaho National Engineering Laboratory, has reviewed and evaluated your request and has concluded that certain requirements of the Code are impractical.
The staff has determined that the extent of coverage obtained for the specific welds covered by this request provides reasonable assurance of the structural reliability and operational readiness of the reactor pressure vessel welds and steam generator nozzle welds. Therefore, pursuant to 10 CFR 50.55a(g)(6)(i),
for Unit 3, relief is granted as requested for Request for Relief 95-04 and, for Units 1 and 2, relief is granted provided that the examination coverage for welds at Units 1 and 2 is as much as that estimated using Unit 3 examinations. The staff's evaluation and conclusions are contained in the enclosed Safety Evaluation. This relief is authorized by law and will not 9605070186 9-60-503
