UNITED STATES NUCLEAR REGULATORY COMMISSION REGION III 2443 WARRENVILLE ROAD, SUITE 210 LISLE, IL 60532-4352 November 23, 2011 Mr. Larry Weber Chief Nuclear Officer Indiana Michigan Power Company Nuclear Generation Group One Cook Place Bridgman, MI 49106

SUBJECT:

D. C. COOK NUCLEAR POWER PLANT - NOTIFICATION OF AN NRC MANAGEMENT OF GAS ACCUMULATION IN EMERGENCY CORE COOLING, DEACY HEAT REMOVAL, AND CONTAINMENT SPRAY SYSTEMS INSPECTION; AND REQUEST FOR INFORMATION 05000315/2012002; 05000316/2012002(DRS)

Dear Mr. Weber:

On January 23, 2012, the U. S. Nuclear Regulatory Commission (NRC) will begin the on-site portion of the Gas Accumulation Management in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems Temporary Instruction at your D.C. Cook Nuclear Power Plant. This inspection will be performed in accordance with NRC temporary instruction (TI) 2515/177. The lead inspector for this inspection is Ms. Caroline Tilton.

In order to minimize the impact that the inspections have on the site and to ensure productive inspections, we have enclosed a request for documents needed for the inspection. The documents have been divided into three groups.

The first group lists information necessary for our initial inspection scoping activities. This information should be available to the lead inspector no later than December 12, 2011. By December 16, 2011, the lead inspector will communicate the initial selected samples.

The second group of documents requested is those items needed to support our in-office preparation activities. This set of documents should be available at the Regional Office no later than January 9, 2012. This information should be separated by information request number, especially if provided electronically (e.g., folder with the information request number). During the in-office preparation activities, the inspectors may identify additional information needed to support the inspection. The lead inspector will provide a list of the additional information needed during the week of January 16, 2012.

The last group includes the additional information above, as well as plant specific reference material. This information should be available to the inspector on January 23, 2012. It is also requested that corrective action documents and/or questions developed during the inspection be provided to the inspector as the documents are generated.

Please send the information to the following e-mail address caroline.tilton@nrc.gov. A hard-copy with the required information is also an acceptable option. If there are questions about the material requested, or the inspection, please call Ms. Tilton at (630) 829-9718.

It is important that these documents are as complete as possible, in order to minimize the number of documents requested during the preparation week or during the on-site inspection.

If no activities were accomplished associated with a specific request, then provide a statement indicating that the request is not applicable.

This letter does not contain new or amended information collection requirements subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection requirements were approved by the Office of Management and Budget, control number 3150-0011. The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid Office of Management and Budget control number.

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 (PARS) component of NRC's document system (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

/RA/
