26-039.pdf
The U.S. Nuclear Regulatory Commission was created as an expert, technical agency to protect
public health, safety, and security, and regulate the civilian use of nuclear materials, including
enabling the deployment of nuclear power for the benefit of society. Among other responsibilities,
the agency issues licenses, conducts inspections, initiates and enforces regulations, and plans for
incident response. The NRC is collaborating with interagency partners to implement reforms
outlined in new Executive Orders and the ADVANCE Act to streamline agency activities and enhance
efficiency.

NRC Issues 100th Renewed License with Diablo Canyon Approvals
ROCKVILLE, Md.—The Nuclear Regulatory Commission has renewed the operating
licenses of the Diablo Canyon Nuclear Power Plant for an additional 20 years, marking the 99th
and 100th renewed commercial reactor operating licenses. 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.
