BEAVER VALLEY POWER STATION, UNITS 1 AND 2 - COMPREHENSIVE ENGINEERING TEAM INSPECTION - INSPECTION REPORT 05000334/2024010 AND 05000412/2024010
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:==
==Dear Barry Blair:==
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
On August 1, 2024, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Beaver Valley Power Station, Units 1 and 2 and discussed the results of this inspection with you and other members of your staff. The results of this inspection are documented in the enclosed report.
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. ML19084A0 30). 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 tele phone 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.
No findings or violations of more than minor significance were identified during this inspection.


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 (10 CFR), Part 2.390, Public Inspections, Exemptions, Requests for Withholding.
This letter, its enclosure, and your response (if any) 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 2.390, Public Inspections, Exemptions, Requests for Withholding.

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a comprehensive engineering team inspection at Beaver Valley Power Station, Units 1 and 2, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.

List of Findings and Violations

No findings or violations of more than minor significance were identified.

Additional Tracking Items

None.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html.

Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.
