SUBJECT: PERRY NUCLEAR POWER PLANTREQUEST FOR INFORMATION
FOR AN NRC TRIENNIAL BASELINE DESIGN BASES ASSURANCE
INSPECTION (TEAM); INSPECTION REPORT 05000440/2020010
Dear Mr. Payne:
On April 20, 2020, the U.S. Nuclear Regulatory Commission (NRC) will begin a Triennial
Baseline Design Bases Assurance Inspection (Team) at Perry Nuclear Power Plant.
This inspection will be performed in accordance with NRC Baseline Inspection
Procedure 71111.21M.
The Design Bases Assurance 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 modifications 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 and modifications to be reviewed during this baseline inspection will be
identified as part of the preparation for the inspection and finalized during the inoffice
preparation week that occurs prior to the first onsite inspection week. In addition, operating
experience issues, associated with the component samples, will also be selected for review.
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 six NRC
inspectors who will focus on engineering/maintenance/operations of the selected components
and modifications. The current inspection schedule is as follows:
- Preparation week: April 13 - 17, 2020
- Onsite weeks: April 20 - 24, 2020; and
May 4 - 8, 2020.

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.
It is important that all 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:
- The first group lists information necessary for our initial inspection scoping activities.
This information should be provided to the lead inspector no later than March 2, 2020.
By March 13, 2020, the lead inspector will communicate the initial selected set of
approximately seven components and seven modifications.
- The second group of documents requested is those items needed to support our
in-office preparation activities. This set of documents, including the calculations
associated with the initially selected components and the modification packages
associated with the initially selected modifications, should be provided to the lead
inspector at the Regional Office no later than April 6, 2020. 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
April 20, 2020. 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 Benny Jose. We understand that our licensing contact
for this inspection is George Dujanovic (440-280-5200) 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

accordance with Title 10 of the Code of Federal Regulations, Part 2.390, Public
Inspections, Exemptions, Requests for Withholding.
