Abstract

This document is a supplement to NUREG-2181, "Safety Evaluation Report Related to the License Renewal of the Sequoyah Nuclear Plant, Units 1 and 2," for the license renewal application (LRA) for Sequoyah Nuclear Plant (Sequoyah or SQN), Units 1 and 2. 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.

This supplement to NUREG 2181 (SSER) documents the staff's review of supplemental information provided by the applicant since the issuance of the Safety Evaluation Report (SER). This evaluation considered TVA's LRA annual updates dated April 22, 2014, August 17, 2015, and August 28, 2015, supplemental information regarding recent industry operating experience related to SQN Unit 1 reactor vessel internals, Commitment No. 28 revisions (pertaining to reactor vessel internals and surveillance capsule monitoring), information required by 10 CFR 54.21(b), as well as information provided in response to staff requests for additional information. This document discusses only the changes to the SER.
