**SUPPLEMENTARY INFORMATION:**
**I. Discussion**
Based upon the application dated March 9, 2022, as supplemented August 10, 2023, September 21, 2023, April 30, 2024, and March 14, 2025, the NRC has issued a renewed license to the licensee for the Diablo Canyon ISFSI, located in San Luis Obispo County, California. The renewed license SNM-2511 authorizes and requires operation of the Diablo Canyon ISFSI in accordance with the provisions of the renewed license and its technical specifications. The renewed license will expire on March 22, 2064.
The licensee's application for a renewed license complies with the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the NRC's rules and regulations. The NRC has made appropriate findings as required by the Act and the NRC's regulations in Chapter 1 of title 10 of the *Code of Federal Regulations* (10 CFR) and sets forth those findings in the renewed license. The agency afforded an opportunity for a hearing in the notice of opportunity for a hearing published in the *Federal Register* on January 10, 2023 (88 FR 1431). An adjudicatory proceeding on the application was then conducted in response to a petition to intervene filed by San Luis Obispo Mothers for Peace (petitioner) regarding the adequacy of the license renewal application. An Atomic Safety and Licensing Board (Board) considered the petition and admitted one contention. The petitioner subsequently withdrew the contention after the licensee supplemented its application with information that the contention had noted was missing. The Board subsequently issued LBP-23-08, terminating the adjudicatory proceeding.
The NRC staff prepared a safety evaluation report for the renewal of the ISFSI license and concluded, based on that evaluation, that the ISFSI will continue to meet the regulations in 10 CFR part 72. The NRC staff also prepared an environmental assessment and finding of no significant impact for the renewal of this license, which was published on November 12, 2024 (89 FR 89056). The NRC staff's environmental assessment included the impacts of continued storage of spent nuclear fuel (as documented in NUREG-2157, “Generic Environmental Impact Statement for Continued Storage of Spent Fuel”). The NRC staff concluded that renewal of this ISFSI license will not have a significant impact on the quality of the human environment.
