Reaching this milestone reflects more than two decades of sustained regulatory oversight and technical rigor under the NRC’s license renewal program. Pacific Gas & Electric Co.’s Diablo Canyon Units 1 and 2 are pressurized-water reactors in Avila Beach, California. Unit 1’s operating license will now expire on Nov. 2, 2044, and Unit 2’s will expire on Aug. 26, 2045. The NRC’s review of the application for renewal of the licenses addressed safety and environmental matters. Both a safety evaluation and a final supplemental environmental impact statement were issued in June 2025. The NRC issued the renewed licenses after receiving documentation from PG&E of the required federal certifications under the Coastal Zone Management Act and the Clean Water Act. The NRC’s safety evaluation and final supplemental environmental impact statement, as well as other information regarding the Diablo Canyon license renewal application, are available on the NRC website, which also contains general information about the license renewal process.
