UNITED STATES NUCLEAR REGULATORY COMMISSION REGION III 2443 WARRENVILLE ROAD, SUITE 210 LISLE, IL 60532-4352 November 23, 2011 Mr. Mark Bezilla Site Vice President FirstEnergy Nuclear Operating Company Perry Nuclear Power Plant P. O. Box 97, 10 Center Road, A-PY-A290 Perry, OH 44081-0097

SUBJECT:

PERRY NUCLEAR POWER PLANT - NOTIFICATION OF AN NRC TRIENNIAL HEAT SINK PERFORMANCE INSPECTION AND REQUEST FOR INFORMATION INSPECTION REPORT 05000440/2012002 (DRS)

Dear Mr. Bezilla:

On February 27, 2012, the U. S. Nuclear Regulatory Commission (NRC) will begin the onsite portion of the Triennial Heat Sink Performance Inspection at your Perry Nuclear Power 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 January 9, 2012. By January 13, 2012, 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 February 13, 2012. 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 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 February 20, 2012.

• The last group includes the additional information above, as well as plant specific reference material. This information should be available onsite to the inspector on February 27, 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.

M. Bezilla The lead 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. 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 onsite inspection.

All requested documents should consist of the time period from the onsite inspection including 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/
