SUBJECT:

ANNUAL ASSESSMENT LETTER - BYRON STATION, UNITS 1 AND 2 (REPORT 05000454/200501; 05000455/200501)

Dear Mr. Crane:

On February 9, 2005, the NRC staff completed its end-of-cycle plant performance assessment of Byron Station, Units 1 and 2. The end-of-cycle review for Byron Station involved the participation of the reactor technical divisions in evaluating performance indicators (PIs) for the most recent quarter and inspection results for the period from January 1 through December 31, 2004. 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.

This performance review and enclosed inspection plan do not include physical protection information. A separate letter designated and marked as Exempt from Public Disclosure in accordance with 10 CFR 2.390 will include the physical protection review and resultant inspection plan.

Overall, Byron Station Units 1 and 2 operated in a manner that preserved public health and safety and fully met all cornerstone objectives. Plant performance of Units 1 and 2 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 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 only baseline inspections at your facility through September 30, 2006.

The enclosed inspection plan details the inspections, less those related to physical protection, scheduled through September 30, 2006. The following infrequently performed inspections are planned to commence during the months shown: Temporary Instruction (TI) 2515/150, Reactor Pressure Vessel Head and Vessel Head Penetration Nozzles (Unit 1) in March 2005, TI 2515/160, Pressurizer Penetration Nozzles and Steam Space Piping Connections in U.S.

Pressurized Water Reactors (Unit 1) in March 2005, Problem Identification and Resolution inspection in June 2005, TI 2515/150 (Unit 2) in September 2005, Biennial Heat Sink inspection in October 2005, and Modifications and 10 CFR 50.59 inspection in March 2006. 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.

C. Crane 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 mid-cycle 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 me at (630) 829-9872 with any questions you may have regarding this letter or the inspection plan.

Sincerely,

/RA/
