This safety evaluation report (SER) documents the technical review of the Oconee Nuclear Station (ONS), Unit Nos. 1, 2, and 3 license renewal application (LRA) by the U.S. Nuclear Regulatory Commission (NRC) staff. By letter dated July 6, 1998, Duke Energy Corporation (Duke) submitted the license renewal application for the ONS in accordance with Title 10 of the Code of Federal Regulations Part 54 (10 CFR Part 54). Duke is requesting renewal of the operating licenses issued under Section 104 of the Atomic Energy Act of 1954, as amended, for the ONS, Unit Nos. 1, 2, and 3 (license numbers DPR-38, DPR-47, and DPR-55, respectively) for a period of 20 years beyond the current expiration dates: midnight, February 6, 2013, for Unit 1; midnight, October 6, 2013, for Unit 2; and midnight, July 19, 2014, for Unit 3.
The ONS is located in Oconee County in northwestern South Carolina on the shores of Lake Keowee. The three-unit nuclear station was constructed during the period from 1967 to 1974. Each unit consists of a Babcock and Wilcox (B&W) pressurized-water reactor nuclear steam supply system designed to generate 2568 MW thermal, or approximately 860 MW electric.
On the basis of its evaluation of the LRA, the staff concludes that: (1) actions have been identified and have been or will be taken with respect to managing the effects of aging during the period of extended operation on the functionality of structures and components that have been identified to require an aging management review under 10 CFR 54.21(a)(1), and (2) actions have been identified and have been or will be taken with respect to time-limited aging analyses that have been identified to require review under 10 CFR 54.21(c). Accordingly, the staff finds that there is reasonable assurance that the activities authorized by a renewed license will continue to be conducted in accordance with the current licensing basis for the ONS, Unit Nos. 1, 2, and 3 during the period of extended operation.
