The Nuclear Regulatory Commission has renewed the operating licenses of Comanche Peak Units 1 and 2 for an additional 20 years.

Unit 1’s operating license now expires on February 8, 2050, and Unit 2’s on February 2, 2053.

The two-unit Comanche Peak nuclear power plant in Glen Rose, Texas, is operated by Luminant. Units 1 and 2 are pressurized-water reactors.

Unit 1’s initial license was issued on April 17, 1990, and was set to expire on February 8, 2030. Unit 2 was first licensed on April 6, 1993, with an expiration date of February 2, 2033.

The review: The review of Comanche Peak's license renewal application proceeded on two tracks, according to the NRC. A safety evaluation report was issued in March, and a final supplemental environmental impact statement was issued in April.

These documents, as well as other information regarding the renewal application, are available on the NRC website, which also contains information about the license renewal process.
