SUBJECT:

RIVER BEND STATION - NOTIFICATION OF AGE-RELATED DEGRADATION INSPECTION (05000458/2025013) AND REQUEST FOR INFORMATION

Dear Phil Hansett:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC) staff will conduct the IP 71111.21N.04, Age-Related Degradation baseline inspection at the River Bend Station, beginning on September 8, 2025. The inspection team will be led by Fabian Thomas from the NRC Region IV office. The team will be composed of three personnel from the NRC Region IV office The inspection will be conducted in accordance with IP 71111.21N.04.

An initial list of documents that the team will review during the information gathering visit are listed in enclosure 1.

During the information gathering visit, the team will also discuss the following inspection support administrative details: office space size and location; specific documents requested to be made available to the team in their office spaces; arrangements for reactor site access (including radiation protection training, security, safety, and fitness for duty requirements); and the availability of knowledgeable plant staff and licensing organization personnel to serve as points of contact during the inspection.

P. Hansett 2

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. (Enclosure 3 lists the team members and their contact information.) 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.

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, under Control Number 3150-0011.

This document request is based on typical documents that a generic plant might have. As such, this document request is not meant to imply that any specific plant is required to have all the listed documents. In addition, your plant-specific document titles may vary from the document titles listed below. We also request that the information provided be sorted by the list below.

Documents requested by July 28, 2025:

1) A list of 50.65 (a)(1) SSCs from the past 5 years

5) List of preventative maintenance deferrals and preventative maintenance change requests in the last 5 years

6) Equipment reliability characterization and preventative maintenance program procedures

7) A list of Title 10 CFR Part 21 Reports that were determined to be applicable to the site from the past 5 years

8) List of corrective action documents associated with component failures, applicable corrective action program trend codes, or keyword search of aging, age-related, wear, accelerated wear, corrosion, abnormal wear, accelerated degradation, and abnormal degradation from the past 5 years. Please include a short description of the issue in the system generated listing.

9) A list of top 100 most risk-significant structures and components according to the site-specific probabilistic risk assessment (PRA). If possible, designate the component as active or passive in the risk ranking.
