Availability Notice


This report supplements the Staff's evaluation of 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). This supplemental evaluation documents the Staff's findings with respect to the applicable elements of Title 10 of the Code of Federal Regulations (10 CFR) 50.57, which lists the findings the Nuclear Regulatory Commission (NRC) must make to issue an operating license.

The application for a construction permit for WBN, Units 1 and 2 was submitted on May 14, 1971, and constructions permits CPPR-91 and CPPR-92 were issued January 23, 1973. Subsequently, on October 4, 1976, an application for operating licenses for WBN, Units 1 and 2 was submitted by TVA. In its safety evaluation report (SER) published June 1982 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML072060491) and Supplemental SERs (SSERs) 1 through 20, issued by the Office of Nuclear Reactor Regulation (NRR) of the NRC, the NRC staff documented its safety evaluation (SE) 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 published February 2009 (ADAMS Accession No. ML090570741), the NRC staff addressed TVA's application for a license to operate WBN, Unit 2, and gave information on the status of the items remaining to be resolved that 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. SSERs 22 to 28 documented the NRC staff's ongoing evaluation and closure of open items in support of TVA's application for a license to operate WBN, Unit 2.

This SSER documents the NRC staff's completion of its review of open items in related to TVA's application for an OL for WBN, Unit 2. In addition to closure of remaining open items, this SSER discusses a revision to the motor operated valve testing program, the fire protection program, the technical specifications, and final SER modifications made by the applicant.
