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).
