SUBJECT: POINT BEACH NUCLEAR PLANT - REQUEST FOR INFORMATION FOR AN
NRC QUADRENNIAL COMPREHENSIVE ENGINEERING TEAM INSPECTION:
INSPECTION REPORT 05000266/2023010; 05000301/2023010
Dear Mr. Strope:
On January 9, 2023, the U.S. Nuclear Regulatory Commission (NRC) will begin a quadrennial
baseline Comprehensive Engineering Team Inspection (CETI) at Point Beach Nuclear Plant.
This inspection will be performed in accordance with NRC Inspection Procedure 71111.21M
which is being revised and should be publicly available in the near future.
The Comprehensive Engineering Team Inspection focuses on the design, maintenance, and
operation of risk significant components with low margin, or associated with an accident
scenario, or a specific system. The inspection also monitors the implementation of changes to
structures, systems, and components as modifications to one system may also affect the
design bases and functioning of interfacing systems as well as introduce the potential for
common cause failures. The components, modifications, 50.59 Evaluations, 50.59 Screenings
and Operating Experiences to be reviewed during this baseline inspection will be identified as
part of the preparation for the inspection and finalized during the first onsite inspection week.
Additionally, the inspection team may request scenarios to be performed on the simulator. This
request would require support from your simulator staff to validate scenarios, simulator time,
and a crew to perform the actions which would most likely occur during the second onsite
week. The team will work closely with your staff early on during the inspection process to
ensure this activity can be accomplished with minimal impact.
The inspection will include 2 weeks onsite. The inspection team will consist of seven NRC
inspectors who will focus on engineering/maintenance/operations of the selected components
modifications, 50.59 Evaluations, 50.59 Screenings and Operating Experiences. The current
inspection schedule is as follows:
Preparation week: January 3 - 6, 2023
Onsite weeks: January 9 - 13, 2023 and January 23 - 27, 2023
Experience with previous baseline design/modification 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.September 13, 2022
M. Strope - 2 -
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 five groups, with their respective due
dates:
October 14, 2022 - The First Group lists information necessary for our initial
risk-informed scoping activities.
October 28, 2022 - The Second Group lists information necessary for our initial
inspection scoping activities (preliminary sample selections).
- November 18, 2022 - The lead inspector will communicate the preliminary
samples selected. This will include Components, Modifications,
50.59 Evaluations and 50.59 Screenings.
December 27, 2022 - The Third Group of documents requested are those items
needed to support our in-office preparation activities. During the in-office preparation
activities, the team may identify additional information needed to support the
inspection.
January 9, 2023 - The Fourth Group includes the additional information identified
during the in-office preparation as well as plant-specific reference material. This
information should be available to the team onsite.
After January 9, 2023 - The Fifth Group includes supporting information to be
provided throughout the inspection. Specifically, corrective action documents and
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 Mr. J. Corujo-Sandin. We understand that our licensing
contact for this inspection is Ms. K. Locke of your organization. If there are any questions about
the inspection or the material requested in the enclosure, please contact the lead inspector at
630-829-9741 or via e-mail at Jorge.Corujo-Sandin@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.
