SUBJECT:
FERMI POWER PLANT, UNIT 2 - NOTIFICATION OF AN NRC TRIENNIAL
HEAT SINK PERFORMANCE INSPECTION AND REQUEST FOR
INFORMATION INSPECTION REPORT 05000341/2009004
Dear Mr. Davis:
On July 6, 2009, the NRC will begin the onsite portion of the Triennial Heat Sink Performance
Inspection at your Fermi Power Plant, Unit 2. 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 May 22, 2009. By
May 29, 2009, 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
June 19, 2009. 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 July 6, 2009. 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.

The lead inspector for this inspection is Gerard ODwyer. If there are questions about the
material requested, or the inspection, please call Gerard ODwyer at (630) 829-9624. Please
send the information to the following e-mail address: Gerard.ODwyer@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 are to be for the time period from the onsite inspection period back to
the last 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.
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).
