UNITED STATES NUCLEAR REGULATORY COMMISSION rch 1, 2017

SUBJECT:

ANNUAL ASSESSMENT LETTER FOR VOGTLE ELECTRIC GENERATING PLANT UNITS 1 AND 2 (REPORT 05000424/2016006 AND 05000425/2016006)

Dear Mr. Taber:

The NRC has completed its end-of-cycle performance assessment of Vogtle Electric Generating Plant Units 1 and 2, reviewing performance indicators (PIs), inspection results, and enforcement actions from January 1, 2016, through December 31, 2016. 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 concluded that overall performance at your facility preserved public health and safety.

The NRC determined the performance at Vogtle Units 1 and 2 during the most recent quarter was within the Regulatory Response Column, the second highest performance column of the NRCs Reactor Oversight Process (ROP) Action Matrix. This conclusion was based on one or more Greater-than-Green inspection findings in the Security Cornerstone originating in the first quarter of 2016, and all PIs within the expected range (i.e., Green). As of January 1, 2017, Vogtle Units 1 and 2 returned to the Licensee Response Column.

Although plant performance was within the Licensee Response Column as of January 1, 2017, the NRC has not yet finalized the significance of AV 05000424, 425/2017503, Transposition Results in Significantly Different EAL Threshold Values, (ML17040A346). The final safety significance determination may affect the NRCs assessment of plant performance and the enclosed inspection plan.

The enclosed inspection plan lists the inspections scheduled through December 31, 2018. The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. Routine inspections performed by resident inspectors are not included in the inspection plan. The inspections listed during the last twelve months of the inspection plan are tentative and may be revised. 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 the plan for security-related inspections, which will be sent via separate, non-publicly available correspondence.

In addition, the NRC will perform Temporary Instruction (TI) 191, Inspection of the Implementation of Mitigation Strategies and Spent Fuel Pool Instrumentation Orders and Emergency Preparedness Communication/Staffing/Multi-Unit Dose Assessment Plans, Appendix A, Mitigation Strategies For Beyond-Design Basis External Events, and TI-192, Inspection of the Licensees Interim Compensatory Measures Associated with the Open Phase Condition (OPC) Design Vulnerabilities In Electric Power Systems.

In accordance with Title 10 of the Code of Federal Regulations (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 Shane Sandal at 404-997-4513 with any questions you have regarding this letter.

Sincerely,

/RA/
