SUBJECT:

RIVER BEND STATION - NOTIFICATION OF COMPREHENSIVE ENGINEERING TEAM INSPECTION (05000458/2023012) AND REQUEST FOR INFORMATION

Dear Kent Scott:

The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission (NRC) staff will conduct the comprehensive engineering team inspection at River Bend Station beginning on July 17, 2023. The inspection team will be composed of seven personnel from the NRC Region IV office. The inspection will be conducted in accordance with NRC inspection procedure (IP) 71111.21M, Comprehensive Engineering Team Inspection, dated October 7, 2022.

The objectives of the inspection are to verify that risk-significant structures, systems, and components (SSCs) have been maintained and will operate within their design and licensing bases requirements; modifications to risk-significant SSCs did not introduce conditions that adversely impact the ability of SSCs to perform their design and licensing bases functions; the design basis, licensing basis, and performance capability of SSCs have not been adversely impacted by changes introduced through degraded conditions and other activities; and that requirements of Title 10 of the Code of Federal Regulations (10 CFR) 50.59 have been appropriately implemented.

The inspection will include an onsite information gathering visit by the team lead and two weeks of onsite inspection by the team. The schedule for the inspection is as follows:

Onsite Information Gathering Visit: June 12-16, 2023 Offsite Preparation Week: July 10-14, 2023 Onsite Inspection Weeks: July 17-21, 2023, and July 31-August 4, 2023

The purpose of the information gathering visit is to meet with your staff to become familiar with River Bends SSCs, programs, processes, and procedures and to ensure the resources needed to support the team, as necessary, to conduct an effective and efficient inspection. This visit may include a tour of installed plant SSCs associated with potential inspection samples. During the visit, the team lead will also review the information provided in the initial information request to select a list of potential inspection samples. The team lead may also identify other information needed to support the inspection during this visit.

K. Scott 2 To minimize the impact on your staff and to ensure an effective and efficient inspection, we have enclosed two separate requests for information needed prior to the onsite information gathering visit and offsite inspection preparation week. The first request (Enclosure 1) is generally for information that will be used to choose the inspection samples or information that will be applicable to all inspection samples throughout the inspection. This information should be made available to the team lead prior to the information gathering visit. The second request (Enclosure 2) is for information that is specific to an individual sample and should be made available prior to the offsite preparation week.

Additional information requests, interviews with your staff, and/or tours of facilities or installed plant components will be made by the team throughout the inspection to complete their review of the selected inspection samples. It is important that all documentation provided to the team is complete and up to date to minimize the number of additional documents requested during the preparation and/or the onsite portions of the inspection. Additionally, to facilitate an efficient inspection, we request that a contact individual be assigned to each inspector to ensure information requests, questions, and concerns are addressed in a timely manner.

We understand that Bridget Johns from your Regulatory Assurance organization is our contact for this inspection. If there are any questions about the inspection or the information requested, please contact the team lead, Dustin Reinert, by telephone at 817-200-1534 or by e-mail at Dustin.Reinert@nrc.gov. Enclosure 3 contains additional contact information for the inspection team.

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. 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.

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.

Sincerely, Vincent G. Gaddy, Chief Engineering Branch 1 Division of Operating Reactor Safety Signed by Gaddy, Vincent on 03/22/23

Documents Requested Prior to 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.

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 of 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 June 2, 2023:

1. Copy of River Bends probabilistic risk assessment (PRA) summary document for the current internal events, external events (e.g., fire, flooding, seismic), and shutdown PRA models of record.

2. From the internal events PRA, a sortable list of structures, systems, and components (SSCs) with risk achievement worth (RAW) and Birnbaum values for both core damage frequency (CDF) and large early release frequency (LERF). Include all basic events with RAW values of 1.3 or greater and Birnbaum values of 1E-6 or greater.

3. From the external events PRA, a sortable list of SSCs with RAW and Birnbaum values for both CDF and LERF. Include all basic events with RAW values of 1.3 or greater and Birnbaum values of 1E-6 or greater.

4. From the internal events PRA, a sortable list of human failure events (HFEs) with RAW and Birnbaum values for both CDF and LERF.

5. From the external events PRA, a sortable list of HFEs with RAW and Birnbaum values for both CDF and LERF.
