SUBJECT: POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2
NOTIFICATION OF AN NRC TRIENNIAL HEAT SINK PERFORMANCE
INSPECTION AND REQUEST FOR INFORMATION 05000266/2012003;
Dear Mr. Meyer:
On Monday, February 25, 2013, the U. S. Nuclear Regulatory Commission (NRC) will begin the
on-site portion of the Triennial Heat Sink Performance Inspection at your Point Beach 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 Monday, January 14,
2013. By Friday, January 18, 2013, the inspector will communicate the initial selected set of
approximately 2-3 risk significant heat exchangers.
- The second group is 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 Monday, February 11, 2013. 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 onsite to the inspector on Monday,
February 25, 2013. 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.

All requested documents are to be for the time period from the onsite 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. 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.
The lead inspector for this inspection is Néstor J. Féliz Adorno. We understand that a
regulatory contact for this inspection is Jim Costedio of your organization. If there are questions
about the material requested, or the inspection, please call Néstor J. Féliz Adorno at (630) 829-
9739. Please send the information to the following e-mail address nestor.feliz-adorno@nrc.gov.
A hard-copy or compact disc (CD) with the required information is also an acceptable option.
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).
