Sequoyah Nuclear Plant, P.O. Box 2000, Soddy Daisy, Tennessee 37384 March 28, 2024 U.S. Nuclear Regulatory Commission Region II Attn: Mr. Louis McKown Branch Chief - Division of Reactor Projects Marquis One Tower 245 Peachtree Center Avenue, NE., Suite 1200 Atlanta, GA 30303-1257 Sequoyah Nuclear Plant, Units 1 and 2 Renewed Facility Operating License Nos. DPR-77 and DPR-79 NRC Docket Nos. 50-327 and 50-328

Subject:

Request for Regulatory Conference (Tennessee Valley Authority - Sequoyah Nuclear Plant)

Reference:

EA-24-008, Sequoyah, Units 1 and 2 - NRC Inspection Report 05000327/2024090 and 05000328/2024090 and Preliminary Greater-Than-Green Finding And Apparent Violation, letter dated March 19, 2024 In the referenced letter, the Nuclear Regulatory Commission (NRC) documented a finding and associated apparent violation that has been preliminarily determined to be of greater than very low safety significance (greater-than-Green, or GTG) related to the failure of the 1B Diesel Generator. Tennessee Valley Authority (TVA) was provided with the opportunity to request a Regulatory Conference or to submit a position on the proposed GTG finding in writing.

Accordingly, TVA respectfully requests a Regulatory Conference to present additional information and our perspective on the facts and assumptions the NRC used to assess the finding and its significance.

The referenced letter indicated that the Regulatory Conference should be held within 40 days of receipt of the letter. TVA requests an extension beyond the 40-day guidance to allow completion of an ongoing 10 CFR 21 evaluation. TVA is working to complete the evaluation in a timely manner but may need the 60-day period allowed by 10 CFR 21.21(a)(1). There is reasonable expectation that the results of the evaluation will provide relevant information needed to support the TVA position at the regulatory conference. TVA management will work with Region II management to establish a mutually agreeable date for the Regulatory Conference.

U.S. Nuclear Regulatory Commission Page 2 March 28, 2024 There are no new regulatory commitments in this letter. If you have any questions, please contact Mr. Rick Medina, Site Licensing Manager, at (423) 843-8129 or rmedina4@tva.gov.
