UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 April 27, 2016 Mr. Joseph W. Shea Vice President, Nuclear Licensing Tennessee Valley Authority 1101 Market Street, LP 3R-C Chattanooga, TN 37 402-2801

SUBJECT:

BROWNS FERRY NUCLEAR PLANT, UNITS 1, 2, AND 3 - REGULATORY AUDIT PLAN FOR MAY 10 - 11, 2016, AUDIT AT EXCEL FACILITY IN ROCKVILLE, MARYLAND, IN SUPPORT OF EXTENDED POWER UPRATE LICENSE AMENDMENT REQUEST (CAC NOS. MF6741, MF6742, AND MF6743)

Dear Mr. Shea:

By letter dated September 21, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML15282A152), as supplemented by letters dated November 13, December 15, and December 18, 2015 (ADAMS Accession Nos. ML15317A361, ML15351A113, and ML15355A413, respectively), Tennessee Valley Authority (the licensee) submitted a license amendment request (LAR) for the Browns Ferry Nuclear Plant, Units 1, 2, and 3. The proposed amendment would increase the authorized maximum steady-state reactor core power level for each unit from 3,458 megawatt thermal (MWt) to 3,952 MWt. This LAR represents an increase of approximately 20 percent above the original licensed thermal power level of 3,293 MWt, and an increase of approximately 14.3 percent above the current licensed thermal power level of 3,458 MWt.

In addition, by letters dated January 28 and 29, 2016 (ADAMS Accession Nos. ML16019A283 and ML16020A111, respectively) the U.S. Nuclear Regulatory Commission (NRC) issued requests for additional information (RAls) to the licensee. The licensee, by letters dated February 16 and March 8, 2016 (ADAMS Accession Nos. ML16049A248 and ML16069A142),

responded to the staff's RAls.

To support its safety evaluations, the NRC staff will conduct an audit with the licensee at the EXCEL Services Corporation facility in Rockville, Maryland, from May 10 to 11, 2016. The audit plan to support the review of the extended power uprate (EPU) LAR regarding spent fuel pool criticality analysis and Boral plates is enclosed.

J.Shea If you have any questions, please contact me at (301) 415-1447 or Farideh.Saba@nrc.gov.

Sincerely,

• -t-r'I Farideh E. Saba, Senior Project Manager Plant Licensing Branch 11-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-259, 50-260, and 50-296

Background

The U.S. Nuclear Regulatory Commission (NRC) staff is currently engaged in a review of a license amendment request (LAR) for the Browns Ferry Nuclear Plant (BFN), Units 1, 2, and 3.

By letter dated September 21, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML15282A152), as supplemented by letters dated November 13, December 15, and December 18, 2015 (ADAMS Accession Nos. ML15317A361, ML15351A113, and ML15355A413, respectively), Tennessee Valley Authority (TVA, the licensee) submitted an LAR for the BFN, Units 1, 2, and 3. The proposed amendment would increase the authorized maximum steady-state reactor core power level for each unit from 3,458 megawatt thermal (MWt) to 3,952 MWt. This LAR represents an increase of approximately 20 percent above the original licensed thermal power level of 3,293 MWt, and an increase of approximately 14.3 percent above the current licensed thermal power level of 3,458 MWt.

In addition, by letters dated January 28 and 29, 2016 (ADAMS Accession Nos. ML16019A283 and ML16020A111, respectively) the U.S. Nuclear Regulatory Commission (NRC) issued requests for additional information (RAls) to the licensee. The licensee, by letters dated February 16 and March 8, 2016 (ADAMS Accession Nos. ML16049A248 and ML16069A142),

responded to the staff's RAls.

The NRC staff has determined that a regulatory audit of the BFN LAR should be conducted in accordance with the Nuclear Reactor Regulation (NRR) Office Instruction LIC-111, "Regulatory Audits," for the NRC staff to gain a better understanding of the licensee's calculations and other aspects of the LAR.

Enclosure

Regulatory Audit Basis The basis of this audit is TVA's LAR and NUREG-0800, "Standard Review Plan for the Review of Nuclear Power Plants: Section 9.1.1, "Criticality Safety of Fresh and Spent Fuel Storage and Handling."

This audit will provide information necessary for the evaluation of the spent fuel pool (SFP) being conducted by NRG staff from the Performance and Code Review Branch, Division of Safety Systems; and Steam Generator Tube Integrity and Chemical Engineering Branch (ESGB), Division of Engineering, NRR.

Regulatory Audit Scope The scope of this regulatory audit will include documents used to support the technical basis for the SFP criticality analysis and neutron absorber (Boral) monitoring program.

Information Necessary for the Regulatory Audit The licensee is requested to have the draft responses available on site for the audit team for the staff request for additional information regarding SFP criticality analysis and Boral monitoring program transmitted to TVA by e-mail on March 22, 2016. The NRG staff requests the licensee to make any analyses or documentation referenced in the draft responses available. The draft responses could be provided electronically or by paper copies. If provided electronically, the licensee is requested to have at least two computers available for the audit team, with a printer connected.

Additional information needs identified during the audit will be communicated to the designated point of contact.

The NRG staff also requests the licensee to make personnel who are familiar with the LAR (including site staff and contractors, if appropriate) accessible upon request (either in person or by phone). The personnel should be able to respond to NRG staff questions.
