Summary

The U.S. Nuclear Regulatory Commission issued Renewed Facility Operating License Nos. DPR-80 and DPR-82 to Pacific Gas and Electric Company for Diablo Canyon Nuclear Power Plant, Units 1 and 2. The renewed licenses authorize continued operation at reactor core power levels not exceeding 3,411 megawatts thermal. The NRC prepared a Record of Decision supporting the license renewal based on the final supplemental environmental impact statement.

What changed

The NRC issued renewed operating licenses DPR-80 and DPR-82 to PG&E for Diablo Canyon Nuclear Power Plant, Units 1 and 2. The licenses authorize continued operation at reactor core power levels not in excess of 3,411 megawatts thermal, in accordance with existing technical specifications. The Record of Decision references the final supplemental environmental impact statement (NUREG-1437, Supplement 62) which concluded that adverse environmental impacts of license renewal are not so great that preserving the option would be unreasonable.\n\nPG&E, as the facility operator, may continue operating Diablo Canyon Units 1 and 2 under the renewed licenses. This is a routine administrative action completing the license renewal process. No new compliance obligations, deadlines, or penalties are associated with this issuance. The license renewal extends the operational authorization for the nuclear facility.

SUPPLEMENTARY INFORMATION:

I. Discussion

Notice is hereby given that the NRC has issued Renewed Facility Operating License Nos. DPR-80 and DPR-82 to PG&E for Diablo
Canyon, Units 1 and 2, respectively. PG&E is the operator of the facility. Renewed Facility Operating License Nos. DPR-80
and DPR-82 authorize PG&E to operate Diablo Canyon, Units 1 and 2, respectively, at reactor core power levels not in excess
of 3,411 megawatts thermal, in accordance with the provisions of the Diablo Canyon licenses and technical specifications.
Notice is also given that the ROD that supports the NRC's decision to issue Renewed Facility Operating License Nos. DPR-80
and DPR-82 is available, and its location is listed in the “Availability of Documents” section of this document.

As discussed in the ROD and the final supplemental environmental impact statement (SEIS), published as NUREG-1437, Supplement
62, “Generic Environmental Impact Statement for License Renewal of Nuclear Plants Regarding License Renewal of Diablo Canyon
Nuclear Power Plant, Units 1 and 2, Final Report,” dated June 2025, the final SEIS documents the NRC staff's environmental
review, including the recommendation that the adverse environmental impacts of license renewal (LR) for Diablo Canyon are
not so great that preserving the option of LR for energy-planning decisionmakers would be unreasonable. This recommendation
is based on (1) the analysis and findings in the NRC's Generic Environmental Impact Statement for License Renewal of Nuclear
Plants, (2) information provided in the environmental report submitted by PG&E, (3) the NRC staff's consultation with Federal,
State, Tribal, and local agencies, (4) the NRC staff's independent environmental review, and (5) the NRC staff's consideration
of public comments received during the scoping process and on the draft SEIS.

Diablo Canyon consists of two pressurized-water reactors located in San Luis Obispo County, California, approximately 12 miles
west-southwest of San Luis Obispo. PG&E submitted its LR application for Diablo Canyon on November 7, 2023, which it supplemented
by letters through February 11, 2026 (see “Availability of Documents” section of this document). The NRC staff has detemined
that PG&E's LR application complies with the standards and requirements of the Atomic Energy Act of 1954, as amended (the
Act), and the NRC's regulations. As required by the Act and NRC regulations in title 10 of the Code of Federal Regulations (10 CFR), the NRC has made appropriate findings, which are set forth in the renewed licenses.

A public notice of the NRC's acceptance for docketing of the LR application and an opportunity to request a hearing was published
in the Federal Register on December 19, 2023 (88 FR 87817).

For further details with respect to this action, see: (1) PG&E's LR application for Diablo Canyon, dated November 7, 2023,
as supplemented by letters through February 11, 2026; (2) the NRC's safety evaluation, dated June 2025; (3) the NRC's final
SEIS, dated June 2025; and (4) the NRC's ROD, dated April 2, 2026.
