SUBJECT:

BROWNS FERRY NUCLEAR PLANT, UNITS 1, 2, AND 3 CORRECTION OF SAFETY EVALUATION FOR ISSUANCE OF AMENDMENT NOS. 325, 348, AND 308 REGARDING APPLICATION OF ADVANCED FRAMATOME METHODOLOGIES, AND ADOP TION OF TSTF-564-A, REVISION 2, SAFETY LIMIT MCPR, IN SUPPORT OF ATRIUM 11 FUEL USE (EPID-L-2021-LLA-0132)

Dear Mr. Barstow:

On January 13, 2023, the U.S. Nuclear Regulatory Commission (NRC) issued Amendment Nos. 325, 348, and 308 to Renewed Facility Operating Licenses Nos. DPR-33, DPR-52, and DPR-68 for the Browns Ferry Nuclear Plant (Browns Ferry), Units 1, 2, and 3, respectively (Agencywide Documents Access and M anagement System (ADAMS) Accession No. ML22348A068 (not publicly available; proprietary information)).

Among other things, the amendments revised Browns Ferry Technical Specification (TS) 5.6.5.b, Core Operating Limits Repor t, to allow application of Advanced Framatome Methodologies for determining core operating limits in support of loading Framatome fuel type ATRIUM 11' under the currently licensed Maximum Extended Load Line Limit Analysis Plus (MELLLA+) operating domain.

A non-proprietary version of the amendments was not yet released to the public to allow Tennessee Valley Authority (TVA) the opportunity to confirm the proprietary markings in the safety evaluation (SE). On January 19, 2023, TVA staff notified the NRC staff of several places in the SE that should have been marked as proprietary. The identified text on SE pages 19, 43, 44, 45, 46, 47, 60, 73, 74, and 93 has been corrected to properly mark the text as proprietary.

The text will be redacted in the non-proprietary version of Amendment Nos. 325, 348, and 308, which will be released to the public.

The Enclosure to this letter contains proprietary information. When separated from the Enclosure, this document is decontrolled.

J. Barstow Additionally, during its review, TVA identified errors or missing text on the SE pages as described below:

Page 25: AREVA ATRIUM 11 should read Framatome ATRIUM 11 Page 46 correction to LPCI line break Page 49: ANP-3934, Appendix A should be ANP-3905, Appendix A Page 82: the condition for 50 percent core power, with 113 percent core flow was omitted Page 87: the maximum MCPR was corrected in ANP-3904, Revision 5, dated July 2022 Page 99: the statement For ECPR values less than should be For ECPR values greater than Page 107: the revision number for Reference 27 is missing Page 108: the date for Reference 36 should be August 2005

The NRC concludes that these corrections do no t change the NRC staffs previous conclusions in the SE, nor do they affect the no significant hazards consideration, as published in the Federal Register on March 8, 2022 (87 FR 13014). The enclosure contains corrected pages 19, 25, 43, 44, 45, 46, 47, 49, 60, 73, 74, 82, 87, 93, 99, 107, and 108 for the proprietary SE for Amendment Nos. 325, 348, and 308. The corrections are denoted by a revision bar in the right margin. These corrections will be reflected in the non-proprietary SE for Amendment Nos. 325, 348, and 308.

If you have any questions regarding this matter, please contact me at (301) 415-1627 or by email at Kimberly.Green@nrc.gov.

Sincerely,

/RA/
