Virgil C. Summer Unit 1 Focused Engineering Inspection Initial Information Request Inspection Procedure:

71111.21N.04, Age-Related Degradation, dated December 15, 2023 (ADAMS ML23318A426)

Inspection Dates:

Information Gathering Week: February 17, 2025 Preparation Week: June 2, 2025 Onsite Week 1: June 9, 2025 Onsite Week 2: June 23, 2025 Inspection Report: 05000395/2025010 (Standalone Inspection Report)

Inspectors:

Adam Ruh (Lead/Mechanical), Teh-Chiun Su (Electrical), and Chase Franklin (Mechanical)

The purpose of this letter is to notify you that three inspectors from Region II will conduct an inspection at your site in accordance with Inspection Procedure 71111.21N.04, Age-Related Degradation. The inspection will evaluate the implementation of the programs regarding age related degradation of SSCs are identified and addressed in a manner that provides reasonable assurance of the safe operation of Virgil C. Summer Nuclear Station. The inspectors will select samples of components that are risk significant and within the scope of the inspection procedure.

On February 17, 2025, Mr. Adam Ruh, a Senior Reactor Inspector from the NRCs Region II office, will begin the inspection with an information gathering visit to the site. The purpose of the information gathering visit is to become familiar with the station maintenance, surveillance, testing, inspection, and condition monitoring programs, become familiar with plant layout, support identification of structures, systems, and components (SSCs) that will be reviewed during the inspection, and, as necessary, obtain plant specific site access training and badging for unescorted site access. An initial list of documents that the team will review during the information gathering visit are listed in enclosure 1.

lists documents that are needed prior to the information gathering visit. Please provide the referenced information to the Region II office by February 10, 2025. Additional documents may be requested during the information gathering visit. The additional information should be provided to the Inspectors in the Region II office by May 26, 2025.

For SSCs that the inspection will review, an initial list of the documents the team will review during the conduct of the inspection are listed in enclosure 2. The team leader will contact you with identified SSCs. Also, personnel should be available at the site during the inspection who are knowledgeable regarding maintenance, surveillance, testing, inspection, and condition monitoring programs.

During the information gathering visit, Mr. Ruh will also discuss the following inspection support administrative details: (1) availability of knowledgeable plant engineering and licensing personnel to serve as points of contact during the inspection, (2) method of tracking inspector requests during the inspection, (3) availability of licensee computer access, (4) working space, (5) arrangements for site access, and (6) other applicable information. During this visit, we would like to identify the component samples for this inspection. Wed like to meet with Aging Program specialists to discuss the upcoming inspection and our sample selection process. We request the working space have a telephone, wireless internet access, access to station procedures and corrective action program documents, and a printer. We will also need an area available for conducting interviews.

In accordance with 10 CFR 2.390 of the NRC rules and practices, a copy of this letter and its enclosures will be available electronically for public inspection in the NRC public document room or from the publicly available records (PARS) component of NRCs document system (ADAMS).

ADAMS is accessible from the NRC Web site.

Your cooperation and support during this inspection will be appreciated. If you have questions concerning this inspection, or the inspection teams information or logistical needs, please contact Adam Ruh, the team leader, in the Region 2 Office at 404-997-4669 or by email at adam.ruh@nrc.gov.

Documents requested for information gathering visit:

The documents and information requested below should generally be made available to the inspection team for the team's use both on-site and off-site during the information gathering visit. Electronic format is the preferred media. If electronic media is made available via an internet based remote document management system, then the remote document access must allow inspectors to download, save, and print the documents in the NRC's regional office. Electronic media on compact disc or paper records (hard copy) are acceptable. At the end of the inspection, the documents in the team's possession will not be retained.
