SUBJECT:

ANNUAL ASSESSMENT LETTER - SAN ONOFRE NUCLEAR GENERATING STATION (NRC REPORT 05000361/2004001; 05000362/2004001)

Dear Mr. Ray:

On February 4, 2004, the NRC staff completed its end-of-cycle plant performance assessment of the San Onofre Nuclear Generating Station. The end-of-cycle review for the San Onofre Nuclear Generating Station involved the participation of all technical divisions in evaluating performance indicators (PI) for the most recent quarter and inspection results for the period from January 1 through December 31, 2003. The purpose of this letter is to inform you of our assessment of your safety performance during this period and our plans for future inspections at your facility so that you will have an opportunity to prepare for these inspections and to inform us of any planned inspections that may conflict with your plant activities.

Overall, the San Onofre Nuclear Generating Station operated in a manner that preserved public health and safety and fully met all cornerstone objectives. Plant performance for the most recent quarter was within the Licensee Response Column of the NRCs Action Matrix, based on all inspection findings being classified as having very low safety significance (Green) and all PIs indicating performance at a level requiring no additional NRC oversight (Green). Therefore, we plan to conduct baseline inspections and Temporary Instructions (TI) 2515/150, Reactor Pressure Vessel Head and Vessel Head Penetration Nozzles (NRC Bulletin 2002-02), TI 2515/153, Reactor Containment Sump Blockage, and TI 2515/154, Spent Fuel Material Control and Accounting at Nuclear Powers Plants, at San Onofre, Units 2 and 3, through September 30, 2005.

While plant performance for the most recent quarter is within the Licensee Response Column of the Action Matrix, Unit 2 plant performance was within the Regulatory Response Column of the NRCs Action Matrix during the first quarter of the assessment cycle. During the first quarter, the Unit 2 performance indicator for Unplanned Scrams per 7000 Critical Hours was White. This performance indicator returned to Green in the second quarter of 2003. A supplemental inspection, performed in accordance with Inspection Procedure 95001, Inspection for One or Two White Inputs in a Strategic Performance Area, determined that you performed a comprehensive and thorough evaluation in which specific problems were identified, an adequate root cause evaluation was performed, and corrective actions were taken or planned to prevent recurrence.

Southern California Edison Co. -2-As you are aware, the NRC has issued several Orders and threat advisories to enhance security capabilities and improve guard force readiness since the terrorist attacks on September 11, 2001. We have conducted inspections to review your implementation of these requirements and have monitored your actions in response to changing threat conditions. For calendar year 2004, we plan to continue inspections of Order implementation combined with newly developed portions of the security baseline inspection program. The enclosed inspection plan details the inspections scheduled through September 30, 2005. The inspection plan is provided to minimize the resource impact on your staff and to allow for scheduling conflicts and personnel availability to be resolved in advance of inspector arrival onsite. Routine resident inspections are not listed due to their ongoing and continuous nature. The inspections in the last 12 months of the inspection plan are tentative and may be revised at the midcycle review meeting.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter and its enclosure will be made available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

If circumstances arise which cause us to change this inspection plan, we will contact you to discuss the change as soon as possible. Please contact Mr. Kriss Kennedy at (817/860-8144)

with any questions you may have regarding this letter or the inspection plan.

Sincerely,

/RA/ by MASatorius for Arthur T. Howell III, Director Division of Reactor Projects Dockets: 50-361 50-362 Licenses: NPF-10 NPF-15 Enclosure:
