SUBJECT: DAVIS-BESSE NUCLEAR POWER STATION - NOTIFICATION OF AN NRC
TRIENNIAL HEAT SINK PERFORMANCE INSPECTION AND REQUEST FOR
INFORMATION; INSPECTION REPORT 05000346/2017001
Dear Mr. Boles:
On Monday, March 20, 2017, the U.S. Nuclear Regulatory Commission (NRC) will begin the
onsite portion of the Triennial Heat Sink Performance Inspection at your Davis-Besse Nuclear
Power Station. This inspection will be performed in accordance with NRC baseline Inspection
Procedure 71111.07, Heat Sink Performance.
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 February 10, 2017. By
February 17, 2017, 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 March 6, 2017. This information should be
separated for each selected component, especially if provided electronically (e.g., folder with
component name that includes calculations, condition reports, and maintenance history).
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 inspectors on March 20, 2017.
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.
B. Boles -2-
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 onsite inspection.
The lead inspector for this inspection is Mr. Néstor J. Féliz-Adorno. We understand that our
licensing contact for this inspection is Mr. P. McCloskey of your organization. If there are any
questions about the inspection or the material requested in the enclosure, please contact the
lead inspector at 630-829-9739 or via e-mail at Nestor.Feliz-Adorno@nrc.gov.
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.
This letter, its enclosure, and your response (if any) will be made available for public inspection
and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document
Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for
Withholding.
Sincerely,
