NRC INSPECTION REPORT NOS. 072-00073/09-01(DNMS);

050-00456/09-08; 050-00457/09-08 - BRAIDWOOD STATION

Dear Mr. Pacilio:

On July 7, 2010, the U.S. Nuclear Regulatory Commission (NRC) completed its inspection of the dry cask storage pad construction activities at the Braidwood 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 July 7, 2010, during an exit meeting, the NRC inspectors discussed the preliminary 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 Commissions rules and regulations and with the conditions of your license. Specifically, the inspectors observed vibro-compaction activities and the placement of the mud mat, structural fill, reinforcement, and concrete for the storage pad.

The inspectors also began an in-office review of structural calculations related to the storage pad and the haul path, however not all documents needed to complete this review were available during the inspection period. 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, observations of activities, and interviews with personnel.

Based on the results of these inspections, the inspectors did not identify any violations of NRC requirements. The storage pad construction activities were conducted in accordance with applicable regulations and license conditions. The licensees calculations and evaluations relating to the pad and haul path analysis were still ongoing so the inspectors could not complete their review in these areas. The NRC inspection of these activities will be completed prior to storage of fuel on the pad. In accordance with 10 CFR 2.390 of the NRCs 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/
