Southern California Edison Company P. 0. BOX 800 2244 WALNUT GROVE AVENUE KENNETH P. BASKIN ROSEMEAD, CALIFORNIA 91770 TELEPHONE VICE PRESIDENT 213-572-1401 November 21, 1983 Mr. H. R. Denton, Director Office of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission Washington, D.C.
20555 Gentlemen:
Subject:
Docket No. 50-206 Integrated Living Schedule San Onofre Nuclear Generating Station Unit 1
Reference:
Letter, Kenneth P. Baskin, SCE to H. R. Denton, NRC, dated September 2, 1983 The referenced letter provided a description of the methodology to be used in developing an Integrated Living Schedule (ILS) for San Onofre Unit 1. This methodology is based on the Westinghouse Analytical Ranking Process. Further details and an example of the application of the process were provided in a meeting with members of the Regulatory Staff on October 5, 1983.
A schedule of all capital backfit projects based on this methodology has now been determined and is enclosed. The projects appearing in the schedule were evaluated using the Westinghouse Process to determine their relative potential for enhancing safe plant operation. The ranked projects were then scheduled based on normal constraints. These constraints include capital expenditures, site craft manpower, required station engineering support, architect engineer support, SCE engineering support and procurement lead times.
It should be noted that several of the projects appearing on the schedule (especially SEP, Environmental Qualification and Supplement 1 to NUREG-0737) do not have specific backfits identified but were ranked based on the current state of knowledge. In these cases, the issue was ranked based on the assumption that modifications would be implemented in accordance with current deterministic regulatory criteria. As you know, ongoing further analyses of these issues may lower their priority or in some instances may completely eliminate them from further consideration. In addition, several of the high priority-projects address either seismic upgrade or evaluation.
Because the project seismic design issues are currently undergoing extensive discussion between the NRC and Southern California Edison Company, the priority of these projects is also subject to change.

.SCE This schedule is being submitted for the Regulatory staff's early review.and comment. Upon resolution of any Regulatory staff comments, a License Amendment will be submitted that will incorporate the schedule and procedures for modifying the schedule into the SONGS 1 license. As previously indicated in our correspondence on this subject and in discussions with you and other members of the Regulatory staff, this schedule is being submitted at this time to support timely formal approval of the plan by year end 1983.
If you have any questions on this schedule or the process, please contact me.
Yours truly, Enclosure
