SUBJECT: CLINTON POWER STATIONREQUEST FOR INFORMATION FOR AN NRC
DESIGN BASES ASSURANCE INSPECTION (PROGRAM): IMPLEMENTATION
OF THE ENVIRONMENTAL QUALIFICATION PROGRAM INSPECTION
REPORT 05000461/2018011
Dear Mr. Hanson:
On October 22, 2018, the U. S. Nuclear Regulatory Commission (NRC) will begin a
Triennial Baseline Design Bases Assurance Inspection (Program) at Clinton Power
Station. This inspection will be performed in accordance with NRC Baseline Inspection
Procedure 71111.21N, Attachment 1.
The Design Bases Assurance Inspection will focus on the implementation of the electrical
equipment Environmental Qualification (EQ) Program to verify you are maintaining the qualified
status of equipment during the life of the plant. The EQ components to be reviewed during this
baseline inspection will be identified during the in-office preparation week that occurs prior to the
onsite inspection week.
The inspection will include two weeks of onsite inspection. The inspection team will consist of
three NRC inspectors. The current inspection schedule is as follows:
Preparation week:
October 15-19, 2018
Onsite inspection weeks:
October 22-26, 2018, and November 5-9, 2018.
Experience with previous baseline design 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. In order to minimize the inspection impact on the site and to ensure a productive
inspection for both parties, we have enclosed a request for information needed for the
inspection.
It is important that all of these documents are up-to-date and complete in order 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:
B. Hanson
-2-
The first group lists information necessary for our initial inspection scoping
activities. This information should be provided to the lead inspector no later than
September 21, 2018. By September 28, 2018, the lead inspector will communicate
the initial selected set of approximately 12 EQ components.
The second group of documents requested is those items needed to support our
in-office preparation activities for the selected set of 9-12 EQ components. This set
of documents should be provided to the lead inspector at the Regional Office no later
than October 5, 2018. During the in-office preparation activities, the team 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 to the team onsite on
October 22, 2018. It is also requested that corrective action documents and/or
questions developed during the inspection be provided to the lead inspector as the
documents are generated.
The lead inspector for this inspection is Mr. Benny Jose. We understand that our licensing
contact for this inspection is Mr. Nicholas Santos of your organization. If there are any
questions about the inspection or the material requested in the enclosure, please contact
the lead inspector at 630-829-9756 or via e-mail at Benny.Jose@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 Title 10 of the Code of Federal Regulations, Part 2.390, Public Inspections,
Exemptions, Requests for Withholding.
Sincerely,
/RA/

Information Requested for Initial Inspection Scoping Activities
The following information is requested by September 21, 2018, or sooner, to facilitate
inspection preparation. If you have any questions regarding this information, please call
the team leader as soon as possible. (Please provide the information electronically in
pdf files, Excel, or other searchable formats, preferably on some portable electronic
media (e.g., CD-ROM, DVD, etc.). The portable electronic media 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).
