UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 March 11, 1985 Docket No.

50-206 LS05-85-03-01 0 Mr.

Kenneth P. Baskin, Vice President Nuclear Engineering Safety and Licensing Department Southern California Edison Company 2244 Walnut Grove Avenue Post Office Box 800 Rosemead, California 91770

Dear Mr. Baskin:

IJEECT:

ENVIRONMENTAL QUALIFICATION OF ELECTRIC EQUIPMENT IMPORTANT TO SAFETY Re:

San Onofre Nuclear Generating Station, Unit No. I The enclosed Safety Evaluation addresses the environmental qualification of electric equipment important to safety for San Onofre Nuclear Generating Station, Unit 1 for compliance with the requirements of 10 CFR 50.49, your proposed resolutions for the deficiencies identified in the Safety Evalua tion dated November 30, 1982, and the June 28, 1982 Franklin Research Center Technical Evaluation Report enclosed with it, and justification for continued operation for those equipment items for which environmental qualification has not yet been completed.

On December 20, 1983, a meeting was held with the Southern California Edison Company to discuss the proposed method of resolution for each of the environmental qualification deficiencies identified. Discussions also included Southern California Edison Company's general methodology for compliance with 10 CFR 50.49, "Environmental Qualification of Electric Equipment Important to Safety for Nuclear Power Plants," which became effective February 22., 1983, and justification for continued operation for those equipment items for which environmental qualification is not yet completed.

You provided a submittal, by letter dated July 30, 1984 addressing the above subjects and documenting the discussions held at the meeting.

An audit of the Environmental Qualification Documentation was conducted on October 2, 3, and 4, 1984, with additional discussions on October 26, 1984.

You then provided two submittals, dated November 3 and November 19, 1984, addressing the subjects discussed during the audit and meetings.

Mr. Kenneth March 11, 1985 Based on discussions during the audit and meetings and the results of our review of your November 3 and November 19, 1984 submittals, we have concluded that Southern California Edison Company's Equipment Qualification Program is in compliance with the requirements of 10 CFR 50.49, since final environmental qualification of electric equipment important to safety either:

(1) will be completed by March 31, 1985, which is the earlier of the two dates specified by 10 CFR 50.49(g) for this facility; or (2) an extension of the implementation date for certain equipment from March 31, 1985 to no later than November 30, 1985 has been reviewed and approved by the NRC, and justification for continued operation has been provided and is acceptable to the staff for all equipment not currently qualified. We therefore conclude that continued operation of San Onofre Generating Station, Unit I will not present undue risk to the public health and safety.
