February 23, 2021 Mr. James Barstow Vice President, Nuclear Regulatory Affairs and Support Services Tennessee Valley Authority 1101 Market Street, LP 4A-C Chattanooga, TN 37402-2801
SUBJECT:
BROWNS FERRY NUCLEAR PLANT, UNITS 1, 2, AND 3 - REGULATORY AUDIT
SUMMARY
RELATED TO REQUEST TO IMPLEMENT 10 CFR 50.69 RISK-INFORMED CATEGORIZATION AND TREATMENT FOR STRUCTURES, SYSTEMS AND COMPONENTS (EPID L-2020-LLA-0162)
Dear Mr. Barstow:
By letter dated July 17, 2020, Tennessee Valley Authority (TVA) submitted a license amendment request that would allow for the voluntary adoption of the requirements of Title 10 of the Code of Federal Regulations, Section 50.69, Risk-informed categorization and treatment of structures, systems and components for nuclear power reactors, at Browns Ferry Nuclear Plant, Units 1, 2, and 3.
To enhance the review of TVAs request, the U.S. Nuclear Regulatory Commission (NRC) staff conducted an audit of supporting documents from December 7, 2020, through January 13, 2021. The NRC staff audited the requested documents to confirm certain information relied upon in the license amendment request. A summary of the regulatory audit is enclosed. The NRC staff did not identify any significant issues during the audit. However, the staff did identify the need for additional information related to the topic of the audit. The NRC staffs request for additional information will be transmitted via separate correspondence at a future date.
Sincerely,
/RA/
Michael J. Wentzel, Project Manager Plant Licensing Branch II-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-259, 50-260, and 50-296

REGULATORY AUDIT
SUMMARY
LICENSE AMENDMENT REQUEST TO ADOPT THE REQUIREMENTS OF 10 CFR 50.69, RISK-INFORMED CATEGORIZATION AND TREATMENT OF STRUCTURES, SYSTEMS, AND COMPONENTS TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT, UNITS 1, 2, AND 3 DOCKET NOS. 50-259, 50-260, AND 50-296
1.0 BACKGROUND
A regulatory audit is an activity undertaken by the U.S. Nuclear Regulatory Commission (NRC) staff to examine and evaluate licensee information with the intent to gain an understanding of, verify, or identify information that will require docketing to support the basis of a licensing or regulatory decision.
By application dated July 17, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20199M373), Tennessee Valley Authority (TVA, the licensee) submitted a license amendment request (LAR) for Renewed Facility Operating License Nos. DPR-33, DPR-52, and DPR-68 for Browns Ferry Nuclear Plant, Units 1, 2, and 3 (Browns Ferry), respectively. The proposed amendments would allow for the voluntary implementation of the provisions of Section 50.69 of Title 10 of the Code of Federal Regulations (10 CFR), Risk-Informed Categorization and Treatment of Structures, Systems and Components for Nuclear Power Reactors, at Browns Ferry.
The NRC staff performed a preliminary review of the LAR and determined that a regulatory audit would assist in the timely completion of the review. The regulatory audit was performed consistent with the NRC Office of Nuclear Reactor Regulation Office Instruction LIC-111, Regulatory Audits, Revision 1, dated October 31, 2019 (ADAMS Accession No. ML19226A274). The NRC staff conducted a regulatory audit that consisted of a remote audit, including discussions with the licensee, from December 7, 2020, through January 13, 2021. The audit plan was initially provided to TVA on December 2, 2020 (ADAMS Accession No. ML20337A439). The NRC staff issued a revision to the audit plan on January 7, 2021 (ADAMS Accession No. ML21007A164). The list of documents uploaded by the licensee in response to the NRC staffs request and examined by the audit team is provided in Section 5.0.
The NRC staff reviewed documents and held discussions with members of TVA on January 12 and 13, 2021, regarding the LAR under staff review. The collective results of the Enclosure
regulatory audit are being used by the NRC staff to finalize requests for additional information (RAIs), which will be issued to TVA at a future date.
2.0 AUDIT ACTIVITIES AND OBSERVATIONS The remote audit was conducted using an online portal and teleconferencing capabilities. The purpose of the audit was to (1) confirm internal licensee information that supports statements made in the LAR, and (2) determine whether the information included in the documents is necessary to be submitted to support a safety conclusion.
Discussions on the topics identified in the attachment of Revision 1 of the audit plan were held with the licensee during audit calls conducted on January 12 and 13, 2021. The NRC staff assessed the information provided during the audit to determine whether additional information would be needed to support a regulatory finding, and therefore, would need to be submitted for review.
3.0 RESULTS OF THE AUDIT During the audit, the NRC staff confirmed information that supported statements made in the LAR. However, the staff identified additional information that is needed to support the staffs regulatory findings. Therefore, subsequent to the audits conclusion, an RAI was sent to the licensee on November 17, 2020 (ADAMS Accession No. ML20322A441).
