SUBJECT: NRC INSPECTION REPORT NO. 072-00068/09-01(DNMS); 05000454/2009009; 05000455/2009009 - BYRON POWER STATION

Dear Mr. Pardee:

On September 9, 2009, the U.S. Nuclear Regulatory Commission (NRC) completed its inspection of the dry cask storage pad construction activities at the Byron Power Station. The purpose of the inspection was to determine whether the dry cask storage pad design and construction activities were conducted safely and in accordance with NRC requirements and design specifications. At the conclusion of the inspection on September 9, 2009, during an exit teleconference, the inspectors discussed the inspection findings with members of your staff. The enclosed report presents the results of this inspection. The inspection was an examination of the dry fuel storage pad construction activities as they related to safety and compliance with the Commission's rules and regulations and with the conditions of your license. The inspectors performed reviews of calculations related to the storage pad including reviews to address Unresolved Items (URI) 07200068/2008001-01 and 07200068/2008001-02. Areas examined during the inspection are identified in the enclosed report. Within these areas, the inspection consisted of selected examinations of procedures and representative records, onsite walk-downs of specific areas, and interviews with personnel.

Based on the results of these inspections, the inspectors did not identify violations of NRC requirements. The storage pad construction activities were conducted in accordance with applicable regulations and license conditions. However, inspectors identified two URIs pertaining to the pad design that require further review.

In accordance with 10 Code of Federal Regulations 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html We will gladly discuss any questions you may have regarding this inspection.

Sincerely,/RA/ Christine A. Lipa, Chief Materials Control, ISFSI and Decommissioning Branch Docket Nos.72-068; 050-454; 50-455 License Nos. NPF-37; NPF-66
