UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 April 6, 2015 Mr. John W. Stetkar, Chairman Advisory Committee on Reactor Safeguards U.S. Nuclear Regulatory Commission Washington, DC 20555-0001

SUBJECT:

RESPONSE TO THE ADVISORY COMMITTEE ON REACTOR SAFEGUARDS REPORT ON THE SAFETY ASPECTS OF THE LICENSE RENEWAL APPLICATION FOR THE SEQUOYAH NUCLEAR PLANT, UNITS 1 AND 2

Dear Mr. Stetkar:

During the 622th meeting of the Advisory Committee on Reactor Safeguards (Committee) held on March 6, 2015, the Committee completed its review of the license renewal application for the Sequoyah Nuclear Plant, Units 1 and 2 (SQN), and the associated final safety evaluation report prepared by the U.S. Nuclear Regulatory Commission (NRC). In the Committees final report, dated March 13, 2015, the Committee recommends renewal of the SQN operating license. The NRC staff appreciates the Committees insights and thorough review of the applicants license renewal application and the staffs associated final safety evaluation report. In particular, the Committees review of issues related to the Reactor Vessel Internals Program, fluence value modeling in the upper core plate, and aging effects due to associated irradiation in the area above the active fuel, were particularly helpful as the staff finalized its evaluation. The Committee recognized that Tennessee Valley Authority has committed to periodic visual inspections of the upper core plate as an appropriate action to resolve the open item and agreed with the staffs consideration.

The NRC staff recognizes the Committees commitment to safety and appreciates its continued support of the license renewal process.

Sincerely,

/RA/

Mark A. Satorius Executive Director for Operations cc: Chairman Burns Commissioner Svinicki Commissioner Ostendorff Commissioner Baran SECY
