June 15,1993 Docket No. 50-423 i
Mr. John F. Opeka Executive Vice President, Nuclear Connecticut Yankee Atomic Power Company Northeast Nuclear Energy Company Post Office Box 270 Hartford, Connecticut 06141-0270
Dear Mr. Opeka:
SUBJECT:
APPROVAL OF REQUEST FOR RELIEF FROM ASME CODE REPAIR REQUIREMENTS FOR ASME CLASS 3-PIPING FOR MILLSTONE 3 (TAC N0. M86147)
This letter is in response to your request for relief from ASME Code.
l requirements submitted by letter dated March ?5, 1993. The enclosed Safety Evaluation addresses the temporary use of a rubber patch, in the repair of a 3-inch service water line according to the guidance in Generic Letter 90-05.
Based on the review summarized in the enclosed Safety Evaluation, the staff concludes that there is reasonable assurance that the integrity of service water piping line 3 SWP-003-067-3 will be maintained until permanent repair can be made, but no later than the next scheduled refueling outage. The staff
)
finds that the use of the rubber patch would provide an acceptable level of j
quality and safety. Therefore, based on the above, the proposed use of a rubber patch is acceptable as an alternative to a Code repair, for the above-mentioned period, and is authorized under 10 CFR 50.55a(g)(6)(i).
Sincerely, Original signed by:
Ronald H. Hernan for: John F. Stolz, Director Project Directorate I-4 Division of Reactor Projects - I/II Office of Nuclear Reactor Regulation
