Mr. J. W. Hampton Vice President, Ocone fite April 12, 1995 Duke Power Company P. 0-. Box 1439 Seneca, SC 29679
SUBJECT:
REQUEST FOR RELIEF NO. 94-06 FOR OCONEE NUCLEAR STATION, UNIT 2 (TAC NO. 91173)
Dear Mr. Hampton:
By letter dated July 18, 1994, you submitted Request for Relief No. 94-06 from the hydrostatic testing requirements of the ASME Code for the Unit 2 second 10-year inservice inspection (ISI) and for the testing of welds following the replacement of the Main Steam System and Steam Drain System valves. The weld joints are on Unit 2 piping which is unisolable from the steam generators. In lieu of the Code-required hydrostatic testing, you propose to perform the alternate examinations specified by Code Cases N-498 and N-416-1.
The staff has reviewed your request and our Safety Evaluation is enclosed. We agree with your determination that hydrostatic testing of the welds would result in hardship without a compensating increase in the level of quality and safety. We also find that the alternative testing specified in Code Cases N-498 and N-416-1 would provide an acceptable level of quality and safety.
Accordingly, pursuant to 10 CFR 50.55a(a)(3)(ii), the alternative testing proposed in Relief Request No. 94-06 is authorized.
Sincerely, Original signed by:
