SUBJECT:
CLINTON POWER STATION - REVISED REQUEST FOR INFORMATION
FOR NRC LICENSE RENEWAL INSPECTION: INSPECTION REPORT
Dear David Rhoades:
On April 1, 2024, the U.S. Nuclear Regulatory Commission issued a request for information letter
to support the performance of NRC Inspection Procedure 71002, License Renewal Inspection, at
Clinton Nuclear Power Plant. The inspection was originally scheduled to begin on
October 21, 2024. The NRC has, after discussion with your staff, rescheduled the inspection to
begin on June 9, 2025. This letter contains a revised request for information to support the
schedule change.
The inspection will evaluate Clintons initial license renewal program plans and implementation
to ensure they are consistent with the requirements of Title 10 of the Code of Federal
Regulations (10 CFR), Part 54, Requirements for the Renewal of Operating Licenses for
Nuclear Power Plants, and Clintons license renewal application. The inspection will include an
evaluation of aging management programs that are planned or in place. The inspection will also
include a review of information and documentation required by 10 CFR 54.
The inspection will include 2 onsite weeks and will consist of 5 NRC inspectors (including the
lead inspector). The current inspection schedule is as follows:
Preparation week:
June 2 - 6, 2025
Onsite weeks:
Week 1: June 9 - 13, 2025
Week 2: June 23 - 27, 2025
Experience with previous baseline inspections of similar depth and length has shown that this
type of inspection is extremely resource intensive, both for the NRC inspectors and the licensee
staff. To minimize the inspection impact on the site and to ensure a productive inspection for
both parties, we have enclosed a request for information.
It is important that all these documents are up-to-date and complete to minimize the number of
additional documents requested during the preparation and/or the onsite portions of the

inspection. Insofar as possible, this information should be provided electronically to the lead
inspector. The information request has been divided into three groups:
The first group of documents requested are those items needed to support our
in-office preparation activities. This set of documents should be provided to the lead
inspector by May 12, 2025. During the in-office preparation activities, the team may
identify additional information needed to support the inspection.
The second group includes supporting information to be provided throughout the onsite
inspection. Specifically, corrective action documents and answers to questions
developed during the inspection are requested to be provided as the documents are
generated.
In addition, the enclosure includes information and requests addressing inspection logistics.
The lead inspector for this inspection is Matthew Domke. We understand that our point of
contact for this inspection is Lydia Dworakowski 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)829-9562 or via email at Matthew.Domke@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,
Senior Reactor Inspector

Division of Operating Reactor Safety

INFORMATION REQUEST
Contact the lead inspector as soon as possible if you have any questions
regarding this information request. Provide the information electronically in pdf
files, Excel, or other searchable formats, preferably via an electronic sharing
service (CERTREC, ShareFile, Box, etc.). Specific Excel formats for various

access to Box, which can be used to upload/download and share documents.
The files should contain descriptive names and be indexed and hyperlinked to
facilitate ease of use. Information in lists should contain enough information to
be easily understood by someone who has knowledge of light water reactor
technology.
