Construction of the two Westinghouse pressurized water reactors began in 1974. Unit 1, originally rated at 1,084 MWe, came online on April 17, 1990. Its current, 40-year operating license is valid until February 8, 2030. Unit 2, 1,124 MWe, followed on April 6, 1993 and is licensed to operate until February 2, 2033 when it has to renew its license. As of 2023, Unit 2 was the fourth-to-last power reactor to come online in the United States, followed only by Units 1 and 2 at Watts Bar and Unit 3 at Vogtle.
In June 2008, the U.S. Nuclear Regulatory Commission (NRC) approved a request to increase the generating capacity of Units 1 and 2 by approximately 4.5% each. Luminant Generation Co. implemented the changes during refueling outages. Unit 1 was uprated in autumn 2008 with a capacity increase of approximately 1,210 to 1,259 MWe and Unit 2, the capacity of which rose from an estimated 1,208 to 1,245 MWe, was uprated in autumn 2009.
