SUBJECT:

WATTS BAR NUCLEAR PLANT UNITS 1 & 2 - NOTIFICATION OF AN NRC FIRE PROTECTION TEAM INSPECTION (FPTI) (NRC INSPECTION REPORT 05000390/2025010, 05000391/2025010) AND REQUEST FOR INFORMATION (RFI)

Dear Delson C. Erb:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC),

Region II staff will conduct a fire protection team inspection at the Watts Bar Nuclear Plant Units 1 & 2 in February of 2025. The inspection team will be led by Philipp Braaten, a Senior Reactor Inspector from the NRC Region II Office. The inspection team will be comprised of three inspectors from the NRC Region II office. The inspection will be conducted in accordance with Inspection Procedure 71111, Attachment 21N.05, Fire Protection Team Inspection, the NRCs baseline fire protection inspection procedure.

On October 29, 2024, in an e-mail exchange between Charles Andrew Barker of your staff and Philipp Braaten, our respective staffs confirmed arrangements for a two-week onsite inspection.

The schedule for the inspection is as follows:

• Week 1 of onsite inspection: February 10-14, 2025

• Week 2 of onsite inspection: February 24-28, 2025 The team lead and senior reactor analyst will work with your staff prior to the start of the inspection to select the scope of structures, systems, and components for evaluation; identify additional documents needed to support the inspection; and obtain unescorted access.

The enclosure to this letter provides an initial list of the documents the team will need for their review. We request that your staff transmit copies of the documents listed in the enclosure to the NRC Region II office for team use in preparation for the inspection. Please send this information so that it will arrive in the NRC Region II office by the dates listed in the enclosure.November 4, 2024 During the weeks leading up to the inspection, the team leader will discuss with your staff the following inspection support administrative details: (1) office space size and location; (2)

specific documents requested to be made available to the team in their office spaces; (3)

arrangements for reactor site access (including radiation protection training, security, safety, and fitness for duty requirements); and (4) the availability of knowledgeable plant staff and licensing organization personnel to serve as points of contact during the inspection.

We request that during the on-site inspection weeks you ensure that copies of analyses, evaluations, or documentation regarding the implementation and maintenance of the station fire protection program, including the success path necessary to achieve and maintain the nuclear safety performance criteria, be readily accessible to the team for their review. Of specific interest for the fire protection portion of the inspection are those documents which establish that your fire protection program satisfies NRC regulatory requirements and conforms to applicable NRC and industry fire protection guidance (i.e., fire protection compliance assessment documents). Also, personnel should be available at the site during the inspection who are knowledgeable regarding those plant systems required to achieve and maintain safe and stable plant conditions, including the electrical aspects of the safe shutdown analysis, reactor plant fire protection systems and features, and the station fire protection program and its implementation.

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.

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 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

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 Philipp Braaten, the team lead inspector, in the Region II office at (404) 997-4651 or philipp.braaten@nrc.gov or me at (404) 997-4518.

Sincerely, Daniel Bacon, Chief Engineering Branch 2 Division of Operating Reactor Safety Docket No. 50-390, 50-391 License No. NPF-90, NPF-96 Enclosures:

NAME P. Braaten D. Bacon DATE 10/31/24 11/04/24 Fire Protection Team Inspection Document Request

The initial request for information (i.e., first RFI) concentrates on providing the inspection team with the general information necessary to select appropriate samples to develop a site-specific inspection plan. The first RFIs requested information is specified below in items A.1 thru A.21, and is requested to be provided by Friday, December 13, or sooner, to facilitate the selection of the specific items that will be reviewed during the onsite inspection weeks.

Electronic format is the preferred format, except where specifically noted. If electronic files are made available via a secure document management service, then the remote document access must allow inspectors to download, save, and print the documents in the NRCs regional office.

If a secure document management service is utilized, it is recommended that a separate folder be used corresponding to each item listed below. Documents should be identified by both document number and noun name. Electronic media on compact disc or paper records (hard copy) are also acceptable.

The inspection team will examine the returned documentation from the first RFI and identify/select specific samples to provide a more focused follow-up request to develop the second RFI. The inspection team will submit the specific selected samples to your staff by Friday, December 20, 2024. We request that the additional information provided from the second RFI be made available by Friday, January 31, 2025.

This document request is based on typical documents that a generic plant might have. As such, this generic document request is not meant to imply that any specific plant is required to have all the listed documents. It is recognized that some documents listed below may not be available for your plant. In addition, the document titles listed below are based on typical industry document names; your plant-specific document titles may vary.
