SUBJECT:

BROWNS FERRY NUCLEAR PLANT - NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION FOR NRC PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION

Dear Jim Barstow:

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

Region II staff will conduct a problem identification and resolution (PI&R) inspection at your Browns Ferry Nuclear Plant, Units 1,2, and 3 during the weeks of November 4 - 8, and November 18 - 22, 2024. The inspection team will be led by Kevin Pfeil, Resident Inspect at Browns Ferry Nuclear Plant. This inspection will be conducted in accordance with the baseline inspection procedure, Procedure 71152, Problem Identification and Resolution, issued on October 31, 2023.

The biennial PI&R inspection and assessment of the licensees Corrective Action Program (CAP) complements and expands upon the resident baseline inspections of routine daily screening of all corrective action program issues, quarterly focused issue reviews, and semiannual trend PI&R reviews.

On August 8, 2024, Kevin Pfeil confirmed with member of your staff, William Webster, Browns Ferry team lead, arrangements for the two-week onsite inspection and the one-day pre-inspection visit.

The enclosure lists documents that will be needed prior to the inspection. Please, provide the referenced information no later than October 7, 2024; and contact Kevin Pfeil with any questions concerning the requested information. The inspectors have worked to minimize your administrative burden by specifically identifying documents necessary for inspection preparation.

If additional documents are required, they will be requested as needed. Prior to the onsite inspection, Kevin Pfeil will discuss with your staff inspection support administrative details including availability of knowledgeable plant engineering and licensing personnel to serve as points of contact during the inspection; method of tracking inspector requests during the inspection; access to licensee computers; working space; arrangements for site access; and other applicable information.August 16, 2024 J. Barstow 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 and its enclosure will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Documents Access and Management System (ADAMS).
