SUBJECT:

POINT BEACH NUCLEAR 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 05000266/2010003; 05000301/2010003 (DRS)

Dear Mr. Meyer:

On June 21, 2010, the 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 (TI) at your Point Beach Nuclear Plant.

These inspections will be performed in accordance with NRCs TI 2515/177.

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 inspections. The documents have been divided into three groups for each inspection.

The first group lists information necessary for our initial inspection scoping activities.

This information should be available to the inspector no later than May 6, 2010. By May 13, 2010, the 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 June 10, 2010. 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 inspector may identify additional information needed to support the inspection.

The last group includes the additional information above as well as plant specific reference material. This information should be available to the inspector on June 21, 2010. 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.

L Meyer Please send the information to the following e-mail address nestor.feliz-adorno@nrc.gov. A hard-copy with the required information is also an acceptable option.

It is important that these documents be 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.

The inspector for this inspection is Néstor J. Féliz Adorno. If there are questions about the material requested, or the inspection, please call Mr. Féliz Adorno at (630) 829-9739.

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/
