SUBJECT: DONALD C. COOK NUCLEAR POWER PLANT, UNITS 1 AND 2 - NOTIFICATION

OF AN NRC TRIENNIAL HEAT SINK PERFORMANCE INSPECTION AND

REQUEST FOR INFORMATION; INSPECTION REPORT 05000315/2017002;

05000316/2017002

Dear Mr. Gebbie:

On June 19, 2017, the U.S. Nuclear Regulatory Commission (NRC) will begin the onsite portion

of the Triennial Heat Sink Performance Inspection at your Donald C. Cook Nuclear Power Plant,

Units 1 and 2. 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 May 5, 2017.

By May 12, 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 June 5, 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,

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

June 19, 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.

J. Gebbie -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. Lionel Rodriguez. We understand that our

licensing contact for this inspection is Mr. Michael B. Ellett of your organization. If there are

any questions about the inspection or the material requested in the enclosure, please contact

the lead inspector at 630-829-9609 or via e-mail at Lionel.Rodriguez@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 and its enclosure 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,

/RA/
