SUBJECT:

VIRGIL C. SUMMER - NOTIFICATION OF NRC SUPPLEMENTAL INSPECTION (95001) AND REQUEST FOR INFORMATION

Dear Eric Carr:

By letter dated December 21, 2023, (ADAMS ML23342A000), the U.S. Nuclear Regulatory Commission (NRC) communicated to you the final significance determination of a finding having low-to-moderate safety significance (White) at Virgil C. Summer. The finding was associated with an NRC-identified violation of Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion XVI, Corrective Action for the failure to identify and correct a condition adverse to quality resulting in the inoperability of the A emergency diesel generator (EDG).

On January 24, 2024, I was notified by your staff of Dominion Energys readiness for the NRC to conduct a supplemental inspection to review the actions taken to address the White finding.

Accordingly, we plan to conduct a supplemental inspection, beginning on March 18, 2024, at Virgil C. Summer using Inspection Procedure 95001, Supplemental Inspection Response to Action Matrix Column 2 (Regulatory Response) Inputs. This on-site inspection is scheduled to be performed March 18 through March 22, 2024.

In order to minimize the impact to your on-site resources and to ensure a productive inspection for both organizations, we have enclosed a request for documents needed for this inspection.

The documents identified are those the inspectors will need prior to and upon their arrival on site. It is important that all of the documents are up-to-date and complete in order to minimize the number of additional documents requested during the on-site portion of the inspection. To the extent possible, please organize the information as specified in the request for information (RFI). Experience has shown that poorly organized files can lead to a less efficient inspection and places additional burden on licensee staff. Secure file server access such as Certrec or SharePoint is preferred. During the inspection, the inspectors may request additional documents. If there are questions regarding the documents or material requested, or if the documents cannot be provided by the due date, please do not hesitate to contact the lead inspector, Jason Parent, at (240) 460-9258. We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Hank Kirkland / Justin Bouknight of your organization.February 12, 2024 E. Carr 2 In accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding, of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records System (PARS) component of the NRC's Agencywide Documents Access and Management System (ADAMS).

ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely, Jeffrey Hamman, Acting Chief Reactor Projects Branch 3 Division of Reactor Projects Docket No. 05000395 License No. NPF-12
