SUBJECT:
BEAVER VALLEY POWER STATION, UNITS 1 AND 2 - INFORMATION
REQUEST FOR QUADRENNIAL BASELINE COMPREHENSIVE
ENGINEERING TEAM INSPECTION; NOTIFICATION TO PERFORM
INSPECTION 05000334/2024010 AND 05000412/2024010
Dear Barry Blair:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
Region I staff will conduct a Comprehensive Engineering Team Inspection (CETI) at Beaver
Valley Power Station, Units 1 and 2. Paul Cataldo, a Senior Reactor Inspector from the NRCs
Region I Office, will lead the inspection team. The inspection will be conducted in accordance
with Inspection Procedure 71111.21M, Comprehensive Engineering Team Inspection (CETI),
dated January 1, 2023 (ADAMS Accession No. ML19084A030). This inspection combines
elements of the Design Basis Assurance Inspection (Teams), the Heat Exchanger/Sink
Performance inspection (71111.07T), and the Evaluations of Changes, Tests and Experiments
inspection (71111.17).
The inspection will evaluate the capability of risk-significant/low-margin components to function
as designed to support proper system operation. The inspection will also include a review of
selected modifications, operating experience, and as applicable, operator actions.
In a telephone call between Paul Cataldo and Hope Gilliam, Beaver Valley Regulatory
Compliance, on May 8, 2024, we confirmed arrangements for an information-gathering and the
two-week onsite inspection. The schedule is as follows:
Information-gathering week: Week of June 17, 2024
Onsite weeks: Weeks of July 15, 2024, and July 29, 2024
The purpose of the information-gathering week is to have discussions with members of your
staff to identify risk-significant components, modifications, operator actions, and operating
experience items. Information and documentation needed to support the inspection will also be
identified. Carey Bickett, a Region I Senior Risk Analyst, will support Paul Cataldo during the
information-gathering week to review probabilistic risk assessment data and identify

components to be examined during the inspection.
Experience with previous baseline design/modification inspections of similar depth and length
has shown this type of inspection is 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 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 two groups:
The first group lists information necessary for our initial inspection scoping activities.
This information should be provided to the lead inspector by June 7, 2024. By
June 24, 2024, the lead inspector will communicate the initial selected set of
components, modifications, 50.59 screenings, and operating experience samples.
The second group of documents requested is those items needed to support our in-
office preparation and on-site activities. This set of documents, specific to the selected
components and modifications, should be provided to the lead inspector no later than
July 8, 2024. During the in-office preparation activities, the team may identify additional
information needed to support the inspection, and those items will be communicated
directly to Hope Gilliam, and selected points-of-contact identified by Hope, to facilitate
the requests.
If there are any questions about the inspection or the material requested in the enclosure,
please contact the lead inspector at (610) 337-5365 or via email at pcc1@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.
