Abstract

This safety evaluation report (SER) documents the technical review of the Sequoyah Nuclear Plant, Units 1 and 2, license renewal application (LRA) by the United States (U.S.) Nuclear Regulatory Commission (NRC) staff (the staff). By letter dated January 7, 2013, Tennessee Valley Authority (TVA or the applicant) submitted the LRA in accordance with Title 10, Part 54, "Requirements for Renewal of Operating Licenses for Nuclear Power Plants," of the Code of Federal Regulations. TVA requests renewal of the operating licenses (Facility Operating License Nos. DPR-77 and DPR-79) for a period of 20 years beyond the current expiration at midnight September 17, 2020, for Unit 1, and at midnight September 15, 2021, for Unit 2.

Sequoyah is located approximately 18 miles (15.3 kilometers) northeast of Chattanooga, TN. The NRC issued the Unit 1 construction permit on May 27, 1970, and operating license on September 17, 1980. The NRC issued the Unit 2 construction permit on May 27, 1970, and operating license on September 15, 1981. Both units are of a pressurized water reactor design. Westinghouse Electric Corporation supplied the nuclear steam supply system, and TVA originally designed and constructed the balance of the plant. The licensed power output for each unit is 3,455 megawatts thermal with a gross electrical output of approximately 1,199 megawatts electric.

This SER presents the staff's review of information submitted through December 11, 2014, the cutoff date for consideration in the SER. The staff identified one open item as part of this review that was resolved. SER Section 1.5 summarizes these open items.
