SUBJECT:

BRAIDWOOD STATION INFORMATION REQUEST FOR AN NRC INSPECTION ASSOCIATED WITH CONTAINMENT SUMP 05000456/2008003(DRS); 05000457/2008003(DRS)

Dear Mr. Pardee:

On March 31, 2008, the NRC will begin an inspection at Braidwood Station. One inspector will perform this 1 week inspection in accordance with NRC Temporary Instruction (TI) 2525/166, Pressurized Water Reactor Containment Sump Blockage. This inspection focuses on commitments made by Braidwood Station in response to Generic Letter (GL) 2004-02, Potential Impact of Debris Blockage on Emergency Sump Recirculation at Pressurized Water Reactors (PWRs).

In order to minimize the inspection impact on the site, and to ensure a productive inspection for both parties, we have enclosed a request for documents needed for the inspection. These documents have been divided into two groups. The first group is required prior to the inspection to ensure that the inspector is adequately prepared. This information should be provided to the Regional Office no later than March 24, 2008.

The second group of requested documents contains additional items that the inspector will review, or need access to, during the inspection, and should be available on the first day of the on-site inspection. It is important that all of these documents are up to date and complete in order to minimize the number of additional documents requested during the preparation and/or the on-site portions of the inspection.

The inspector for this inspection is Caroline E. Acosta Acevedo. If there are any questions about the inspection or the materials requested, please contact the inspector at (630) 829-9718 or via e-mail at caroline.acosta@nrc.gov.

C. Pardee In accordance with 10 CFR 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 Publicly Available Records System (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

/RA/
