SUBJECT:

PALISADES NUCLEAR PLANT - NOTIFICATION OF AN NRC TRIENNIAL HEAT SINK PERFORMANCE INSPECTION AND REQUEST FOR INFORMATION INSPECTION REPORT 05000255/2010003 (DRS)

Dear Mr. Schwarz:

On May 26, 2010, the NRC will begin the on-site portion of the Triennial Heat Sink Performance Inspection at your Palisades Nuclear Plant. This inspection will be performed in accordance with NRC baseline inspection procedure (IP) 71111.07.

In order to minimize the impact that the inspection has on the site and to ensure a productive inspection, 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 April 19, 2010. By April 26, 2010, the inspector will communicate the initial selected set of approximately 2 - 3 risk-significant heat exchangers.

The second group of documents requested is those items needed to support our in-office preparation activities. This set of documents, including the calculations associated with the selected heat exchangers, should be available at the Regional Office no later than May 10, 2010. This information should be separated for each selected component, especially if provided electronically (e.g., folder with component name that includes calculations, condition reports, maintenance history, etc.). 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 on-site to the inspector on May 24, 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.

C. Schwarz The lead inspector for this inspection is Michael A. Jones Jr. If there are questions about the material requested, or the inspection, please call Mr. Jones at (630) 829-9745. Please send the information to the following e-mail address michael.jones@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.

All requested documents are for the time period from the on-site inspection period back to the documents that were provided in response to the previous heat sink performance inspection. If no activities were accomplished in that time period, then the request applies to the last applicable document in the previous time period.

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/
