BASKIN December 7, 1982 TELEPHONE MANAGER OF NUCLEAR ENGINEERING, (213) 572-1401 SAFETY, AND LICENSING Director of Nuclear Reactor Regulation Attention: D. M. Crutchfield, Chief Operating Reactors Branch No. 5 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D.C.
20555 Gentlemen:
Subject:
Docket No. 50-206 Systematic Evaluation Program San Onofre Nuclear Generating Station Unit 1 Your letter dated November 12, 1982 provided information concerning the completion of several safety topics for the San Onofre Unit 1 integrated assessment. Attached to your letter was a listing of Draft Safety Evaluations on which we have not provided final comments and a listing of topics for which we have not yet submitted Draft Safety Assessments. This letter provides a schedule for completion of these topics.
The twelve topics for which Draft Safety Evaluations have been received will have final comments issued on or before January 15, 1983. Draft Safety Assessments for Topic III-5.A, High Energy Line Break Inside Containment and III-5.B, High Energy Line Break Outside Containment will be submitted on the following schedule:
Topic Submittal Date III-5.B, Final Report December 15, 1982 III-5.A, Criteria, Methodology January 19, 1983 and Break Identification III-5.A, Final Report February 16, 1983 The Draft Safety Assessment for Topic III-3.A, will not be submitted until the staff has completed their review of Topics III-3.A, Hydrologic Description, and II-3.B, Flooding Potential and Protection Requirements which are required as input to Topic III-3.A. Our evaluation of this topic will be submitted six weeks after completion of Topics II-3.A and II-3.B.

December 7, 1982 As noted at the November 10, 1982 meeting with members of the NRC staff, the effort that would normally be expended by SCE on completing these topics has been substantially impacted by the seismic reevaluation program currently in progress. Not only do results from the seismic upgrade frequently affect the SEP topics, such as III-5.A and III-5.8 mentioned above, but the higher priority assigned to improving the seismic withstand capability of San Onofre Unit 1, including the time necessary to work on the problems associated with attaining resolution on program scope and criteria, has required shifting large amounts of manpower that might otherwise have expedited completion of several SEP topics. It should also be noted that although SCE has not provided our final input to the previously indicated topics, according to NUREG-0485, Volume 4, No. 9, there are over 15 topics on which SCE is currently awaiting NRC response.
If you require further information, please let me know.
Very truly yours,
