ANNUAL ASSESSMENT LETTER FOR DIABLO CANYON POWER PLANT, UNITS 1 AND 2 (REPORT 05000275/2014001 AND 05000323/2014001)

Dear Mr. Halpin:

On February 17, 2015, the Nuclear Regulatory Commission (NRC) completed its end-of-cycle performance review of Diablo Canyon Power Plant, Units 1 and 2. The NRC reviewed the most recent quarterly performance indicators (PIs) in addition to inspection results and enforcement actions from January 1, 2014, through December 31, 2014. This letter informs you of the NRCs assessment of your facility during this period and its plans for future inspections at your facility.

The NRC determined the performance at Diablo Canyon Power Plant, Units 1 and 2, during the most recent quarter was within the Regulatory Response Column of the NRCs Reactor Oversight Process (ROP) Action Matrix because of one White finding in the Emergency Preparedness Cornerstone, for Units 1 and 2. In a letter to you, dated September 2, 2014, the NRC provided its mid-cycle 2014 assessment indicating that the performance at Diablo Canyon Power Plant, Units 1 and 2, was within in the Licensee Response Column of the NRCs ROP Action Matrix, though the NRC was still reviewing unresolved item URI 05000275/2013005-01; 05000323/2013005-01, Procedures for Recommending Protective Actions for Members of the Public on the Pacific Ocean.

In a letter to you, dated February 11, 2015, the NRC provided its final significance determination associated with an inspection finding in the Emergency Preparedness cornerstone for Units 1 and 2 (relative to the aforementioned unresolved item). The finding, which we concluded was of low to moderate safety significance (White), involved the failure to obtain prior approval for an emergency plan change that reduced the effectiveness of the emergency plan. Specifically, on November 4, 2005, without approval from the NRC, Diablo Canyon Power Plant staff removed instructions in emergency plan implementing procedures for making protective action recommendations for members of the public on the ocean within the 10-mile Emergency Planning Zone, reducing the plans effectiveness. Given the significance of the finding referenced above, the NRC determined the performance at Diablo Canyon Power Plant, Units 1 and 2, to be in the Regulatory Response Column of the ROP Action Matrix beginning the fourth quarter of 2014. The NRC plans to conduct a supplemental inspection to review the actions taken to address the performance issues associated with the White finding in accordance with Inspection Procedure 95001, Supplemental Inspection for One or Two White Inputs in a Strategic Performance Area. The NRC will plan this inspection activity when you provide written notification of your readiness for the inspection.

This supplemental inspection will provide assurance that the root causes and contributing causes of the risk-significant performance issues are understood, that the extent of condition and extent of cause of risk-significant performance issues are identified, and that your corrective actions for risk-significant performance issues are sufficient to address the root and contributing causes and prevent recurrence.

The enclosed inspection plan lists the inspections scheduled through June 30, 2016. Routine inspections performed by resident inspectors are not included in the inspection plan. The inspections listed during the last nine months of the inspection plan are tentative and may be revised at the mid-cycle performance review. The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. The NRC will contact you as soon as possible to discuss changes to the inspection plan should circumstances warrant any changes. This inspection plan does not include security-related inspections, which will be sent via separate, non-publicly available correspondence.

Additionally, an NRC audit of licensee efforts towards compliance with Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events, and Order EA-12-051, Order Modifying Licenses with Regard to Reliable Spent Fuel Pool Instrumentation is ongoing. This audit includes an onsite component in order for the NRC to evaluate mitigating strategies as described in licensee submittals, and to receive and review information relative to associated open items. This onsite activity will occur in the months prior to the first unit at each site achieving compliance with the Orders, and will aid staff in development of a Safety Evaluation for the site. The onsite component at your site has been scheduled for the week of August 17, 2015. A site-specific audit plan for the visit will be provided in advance to allow sufficient time for preparations.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter will be 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). Please contact Wayne Walker at (817) 200-1148 with any questions you have regarding this letter.

Sincerely,

/RA/
