The U.S. Nuclear Regulatory Commission (NRC) has published the final, plant-specific, Supplement 48 to the “Generic Environmental Impact Statement for License Renewal of Nuclear Plants (GEIS)” on 20-year license renewals for the 2,700-MW South Texas Project (STP) nuclear plant.
The STP site is located in Bay City, Texas. Possible alternatives to the proposed action (which is license renewal) include no action and reasonable alternative energy sources, with the final decision for the license renewals.
The NRC received an October 2010 application from STP Nuclear Operating Co. (STPNOC) to renew the operating licenses for STPNOC, the agency said in a notice to be published in the Nov. 26 Federal Register. Renewal of the license would authorize the applicant to operate the facility for an additional 20-year period beyond the period specified in the current operating licenses. The current operating licenses for STPNOC Units 1 and 2 expire on Aug. 20, 2027, and Dec. 15, 2028.
The final Supplemental Environmental Impact Statement (SEIS) is being issued as part of the NRC’s process to decide whether to issue renewed licenses to STPNOC.
STP Nuclear Operating manages the plant for its owners, who share its energy in proportion to their ownership interest: Austin Energy, 16%; CPS Energy, 40%; and NRG Energy, 44%. STP’s reactors went online in August 1988 and June 1989, making them among the youngest in the U.S. nuclear generating fleet.
