SUBJECT:

ANNUAL ASSESSMENT LETTER- BYRON STATION, UNITS 1 AND 2, 05000454/2012001 AND 05000455/2012001

Dear Mr. Pacilio:

On February 12, 2013, the Nuclear Regulatory Commission (NRC) staff completed its end-of-cycle performance review of Byron Station, 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, 2012, through December 31, 2012. This letter informs you of the NRCs assessment of your facility during this period and its plans for future inspections at your facility.

Overall, Byron Station, Units 1 and 2, operated in a manner that preserved public health and safety and met all cornerstone objectives.

Plant performance for the most recent quarter, as well as the first three quarters of the assessment period at Byron Station, Units 1 and 2, was within the Licensee Response Column of the NRCs Reactor Oversight Process (ROP) Action Matrix, because all inspection findings had very low (i.e., Green) safety significance, and all PIs indicated that your performance was within the nominal, expected range (i.e., Green).

Therefore, the NRC plans to conduct ROP baseline inspections at your facility. The NRC also plans to conduct Phase II of Temporary Instruction 2515/182, Review of Implementation of Industry Initiative to Control Degradation of Underground Piping and Tanks, at your facility.

The enclosed inspection plan lists the inspections scheduled through December 31, 2014.

Routine inspections performed by resident inspectors are not included in the inspection plan.

The inspections listed during the last 12 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. 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).

Please contact me at 630-829-9620 with any questions you may have regarding this letter or the inspection plan.

Sincerely,

/RA/
