Vistra moves to extend operation at Comanche Peak
Vistra Corporation announced yesterday that it is seeking 20-year life extensions for its Comanche Peak reactors and has submitted an application for license renewals to the Nuclear Regulatory Commission.
Operated by Vistra subsidiary Luminant and located in Glen Rose, Texas, Comanche Peak is home to two Westinghouse-supplied pressurized water reactors. The 1,218-MWe Unit 1 began commercial operation in August 1990, with the 1,207-MWe Unit 2 joining in August 1993. The original 40-year licenses for Units 1 and 2 expire in February 2030 and February 2033, respectively.
