NUCLEAR REGULATORY COMMISSION
REGION III
2443 WARRENVILLE RD. SUITE 210
LISLE, IL 60532-4352

Mr. Paul Fessler
Chief Nuclear Officer
DTE Energy Company
Fermi 2 - 210 NOC
6400 North Dixie Highway
Newport, MI 48166
SUBJECT: FERMI POWER PLANT - NOTIFICATION OF AN NRC TRIENNIAL HEAT
SINK PERFORMANCE INSPECTION AND REQUEST FOR INFORMATION
INSPECTION REPORT 05000341/2016002
Dear Mr. Fessler:
On May 16, 2016, the U.S. Nuclear Regulatory Commission (NRC) will begin the onsite portion
of the Triennial Heat Sink Performance Inspection at your Fermi Power Plant. This inspection
will be performed in accordance with NRC baseline Inspection Procedure 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 18, 2016.
By April 25, 2016, 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 May 2, 2016. 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
May 16, 2016. 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
P. Fessler -2-
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 onsite inspection.
The lead inspector for this inspection is Mr. Michael A. Jones Jr. We understand that
our regulatory contact for this inspection is Mr. Steven Ward of your organization. If there
are questions about the material requested, or the inspection, please call the lead inspector
at 630-829-9745. Please send the information to e-mail address Michael.Jones@nrc.gov.
A hard-copy 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 Title 10 of the Code of Federal Regulations (10 CFR) 2.390, Public
Inspections, Exemptions, Requests for Withholding, of the NRC's "Rules of Practice," a copy
of this letter, its enclosure, and your response (if any) will be available electronically for public
inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS)
component of the NRC's Agencywide Documents Access and Management System (ADAMS).
ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html
