REGU UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 December 13, 1996 Mr. J. W. Hampton Vice President, Oconee Site Duke Power Company P. 0. Box 1439 Seneca, SC.29679
SUBJECT:
THIRD TEN-YEAR INTERVAL INSERVICE INSPECTION PROGRAM PLAN REQUEST FOR RELIEF NO. 96-01 FOR OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 (TAC NOS. M94895, M94896, M94897)
Dear Mr. Hampton:
By letter dated February 27, 1996, you submitted Request for Relief No. 96-01 from certain requirements of the American Society of Mechanical Engineers (ASME) Code,Section XI, 1989 Edition for Oconee Nuclear Station Units 1, 2, and 3. Supplemental information was supplied by letter dated September 5, 1996. In these letters, relief was requested from the Third Ten-Year Interval Inservice Inspection Program Plan to allow Duke Power to take credit for limited ultrasonic examinations on pressurizer nozzle-to-vessel welds and steam generator tubesheet-to-shell welds. During the examinations of the welds on Unit 1 and based on the similar coverage limitations expected to exist on Units 2 and 3, Duke Power determined that the ultrasonic examination coverage could not meet the coverage requirements of the ASME Code due to piping geometry, joint configuration, and interferences.
The staff's evaluation and conclusions are contained in Enclosure 1. is the Technical Letter Report prepared by our contractor, the Idaho National Engineering Laboratory (INEL).
The staff, with technical assistance from INEL, has reviewed and evaluated your request and has concluded that certain requirements of the Code are impractical.
The staff has determined that the requirements of the Code are impractical and the extent of coverage obtained for the specific welds covered by the alternative examination provides reasonable assurance of the structural reliability and operational readiness of the pressurizer nozzle-to-vessel welds and steam generator tubesheet-to-shell welds. Therefore, pursuant to 10 CFR 50.55a(g)(6)(i), request for relief is granted for Unit 1. Relief is also granted for Units 2 and 3, pursuant to 10 CFR 50.55a(g)(6)(i), provided that actual examination coverages for the same component welds in Units 2 and 3 are equal to, or greater than, those described by Duke Power for Unit 1.
