This safety evaluation report (SER) documents the technical review of the South Texas Project (STP), Units 1 and 2, license renewal application (LRA) by the U.S. Nuclear Regulatory Commission (NRC) staff (the staff). By letter dated October 25, 2010, South Texas Nuclear Operating Company (STPNOC or the applicant) submitted the LRA in accordance with Title 10, Part 54, of the Code of Federal Regulations, "Requirements for Renewal of Operating Licenses for Nuclear Power Plants" (10 CFR Part 54). The applicant requests renewal of the STP operating licenses (Facility Operating License Numbers DPR-76 and DPR-80, respectively) for a period of 20 years beyond the current license periods ending August 20, 2027 (Unit 1), and December 15, 2028 (Unit 2).
STP is located near the town of Matagorda, Texas, in Matagorda County, Texas. The staff issued the original construction permits for STP on December 22, 1975 (both units), and the operating licenses on August 20, 1987 (Unit 1), and December 15, 1988 (Unit 2). Each unit's nuclear steam supply system consists of a 4-loop pressurized-water reactor (PWR) designed by Westinghouse Electric Corporation. The primary containment for each unit is a dry ambient design. The balance of plant was designed and constructed by Bechtel Corporation. Both units operate at a licensed power output of 3,853 MWt, with a net electrical power output of 1,250 MWe each. The updated final safety analysis report contains details of the plant and the site.
Unless otherwise indicated, this SER presents the status of the staff's review of information submitted through May 2, 2017, the cutoff date for consideration in this SER. The open item previously identified in the SER with Open Items, issued October 2016, has been closed (see Section 1.5); therefore, no open items remain to be resolved before the final determination is reached by the staff on the LRA.
