SUBJECT:

ANNUAL ASSESSMENT LETTER - DIABLO CANYON POWER PLANT (NRC INSPECTION REPORT 05000275/2007001 and 05000323/2007001)

Dear Mr. Keenan:

On February 8, 2007, the NRC staff completed its performance review of Diablo Canyon Power Plant, Units 1 and 2. Our technical staff reviewed performance indicators for the most recent quarter and inspection results for the period from January 1 through December 31, 2006. 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.

This performance review and enclosed inspection plan do not include physical protection information. A separate letter designated and marked as "Official Use Only - Security-Related Information" will include the physical protection review and resultant inspection plan.

Overall, Diablo Canyon Power Plant, Units 1 and 2, operated in a manner that preserved public health and safety and fully met all cornerstone objectives. Plant performance for the most recent quarter, as well as for the first three quarters of the assessment cycle, was within the Licensee Response column of the NRC's Action Matrix, based on all inspection findings being classified as having very low safety significance (Green) and all performance indicators indicating performance at a level requiring no additional NRC oversight (Green). Therefore, we plan to conduct reactor oversight process baseline inspections at your facility.

The NRC staff identified that there were more than three Green inspection findings for the current 12-month assessment period with documented crosscutting aspects in the human performance area. There is a crosscutting theme associated with these findings involving the adequacy of design documentation and procedures. In evaluating the scope of efforts and progress in addressing the crosscutting theme, we determined that your staff previously recognized this theme and are continuing to implement effective actions to address it. In March 2005, your staff initiated a comprehensive 5-year plan to improve the quality of plant procedures. Most of the findings identified during this assessment period were associated with procedures that had not been enhanced as part of this long-term improvement initiative. In addition to the procedure upgrade program, your staff initiated an apparent cause evaluation of

Pacific Gas and Electric Company -2-the most recent findings. At this time, we have determined that your current and planned corrective actions are effective in mitigating this crosscutting theme. Therefore, the NRC staff has concluded that a substantive crosscutting issue in human performance does not exist at this time.

The enclosed inspection plan details the inspections, except those related to physical protection, scheduled through September 30, 2008. In addition to the baseline inspections, the NRC will also be conducting inspections related to Temporary Instruction 2515/166, Pressurized Water Reactor Containment Sump Blockage, for Units 1 and 2. The inspection plan is provided to allow for the resolution of any scheduling conflicts and personnel availability issues well in advance of inspector arrival onsite. Routine resident inspections are not listed due to their ongoing and continuous nature. The inspections in the last 9 months of the inspection plan are tentative and may be revised at the midcycle review.

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 NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/readina-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 me at 817-860-8141 with any questions you may have regarding this letter or the inspection plan.
