This report supplements the safety evaluation report (SER), NUREG-0847 (June 1982), Supplement No. 23 (July 2011, Agencywide Documents Access and Management System (ADAMS) Accession No. ML11206A499), with respect to the application filed by the Tennessee Valley Authority (TVA), as applicant and owner, for a license to operate Watts Bar Nuclear Plant (WBN) Unit 2 (Docket No 50-391).
In its SER and Supplemental SER (SSER) Nos. 1 through 20 issued by the Office of Nuclear Reactor Regulation (NRR) of the U.S. Nuclear Regulatory Commission (NRC or the staff), the staff documented its safety evaluation and determination that WBN Unit 1 met all applicable regulations and regulatory guidance. Based on satisfactory findings from all applicable inspections, on February 7, 1996, the NRC issued a full-power operating license (OL) to WBN Unit 1, authorizing operation up to 100-percent power.
In SSER 21, the staff addressed TVA’s application for a license to operate WBN Unit 2, and provided information regarding the status of the items remaining to be resolved, which were outstanding at the time that TVA deferred construction of WBN Unit 2, and were not evaluated and resolved as part of the licensing of WBN Unit 1. Beginning with SSER 22, the staff documented its ongoing evaluation and closure of open items in support of TVA’s application for a license to operate WBN Unit 2.
In this and future SSERs, the staff continues its documentation of its review of open items in support of TVA’s application for an operating license for WBN Unit 2.
