SUBJECT:

SEQUOYAH NUCLEAR PLANT, UNITS 1 AND 2 - NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION FOR NRC PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION

Dear Mr. 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 Sequoyah Nuclear Plant during the weeks of June 12-16, 2023 and June 26-30, 2023. The inspection team will be led by Mr. Robert Wehrmann, NRC Resident Inspector from Watts Bar Nuclear Plant. This inspection will be conducted in accordance with baseline inspection procedure 71152, Problem Identification and Resolution, issued December 14, 2021.

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 CAP issues, quarterly focused issue reviews, and semiannual trend PI&R reviews.

On March 27, 2023, Mr. Son Ninh confirmed with Mr. Andrew Clair McNeil, Sequoyah Licensing Program Manager, arrangements for the two weeks of the inspection.

The enclosure lists documents that will be needed prior to the inspection. Please have the referenced information available no later than May 12, 2023. Contact Mr. Wehrmann or Mr. Ninh with any questions concerning the requested information. The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for inspection preparation.

J. Barstow 2 If additional documents are needed, they will be requested when identified. Prior to the inspection, Mr. Wehrmann will discuss with your staff the following inspection support administrative details: 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; and if necessary: access to licensee computers; working space; arrangements for site access; and other applicable information.

This letter, its enclosure, and your response (if any) 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 Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.
