SUBJECT: D.C. COOK NUCLEAR POWER PLANT

REQUEST FOR INFORMATION NRC INSPECTION OF TEMPORARY

INSTRUCTION 2515/166 05000315/2008003(DRS); 05000316/2008003(DRS)

Dear Mr. Rencheck:

On May 12, 2008, the NRC will begin an inspection at the D.C. Cook Nuclear Power Plant. 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 D.C. Cook Nuclear Power Plant 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 of documents are 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 April 28, 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 by 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 material requested, please contact the inspector at (630) 829-9718 or via

e-mail at caroline.acosta@nrc.gov.
