Special Nuclear Materials License No. SNM-7007 was issued on February 13, 2026.

SUPPLEMENTARY INFORMATION:

I. Discussion

The NRC issued a license to TRISO-X for its HALEU fuel fabrication facility in Oak Ridge, Roane County, Tennessee. Special Nuclear Materials License No. SNM-7007 authorizes TRISO-X to operate its facility as proposed in its license application and to possess and use SNM to manufacture HALEU fuel at the TRISO-X Fuel Fabrication Facility. The license authorizes TRISO-X to possess enriched uranium containing less than 20 weight percent uranium 235 for a license period of 40 years. TRISO-X is required to operate under the conditions listed in Materials License No. SNM-7007.

The NRC staff's ROD that supports issuance of Materials License No. SNM-7007 was published on February 13, 2026. The ROD satisfies the regulatory requirement in paragraph 51.102(a) of title 10 of the Code of Federal Regulations (10 CFR), which requires that a Commission decision on any action for which a final environmental impact statement (EIS) has been prepared be accompanied by or include a concise public ROD. As discussed in the ROD, the final EIS for TRISO-X's license application for a fuel fabrication facility in Oak Ridge, Roane County, Tennessee was issued on February 12, 2026, and noticed in the Federal Register on February 13, 2026 (91 FR 6906).

The NRC staff prepared a final safety evaluation report that documents the staff's safety and security review of the application.

The staff's safety and security review found that the application meets applicable NRC regulations in 10 CFR part 70, "Domestic Licensing of Special Nuclear Material." Documents related to the application are available under Docket ID NRC-2022-0209. These documents for the TRISO-X license include the license application, the integrated safety analysis summary, emergency plan, fundamental nuclear material control plan, physical security plan, environmental report and the NRC staff's final safety evaluation report, final EIS, and ROD.

TRISO-X's request for a materials license, an opportunity to request a hearing and to petition for leave to intervene was previously noticed in the Federal Register on February 3, 2023 (88 FR 7473). No individuals filed petitions to intervene.

In issuing a materials license for the TRISO-X Fuel Fabrication Facility, the NRC determined based on its review of the application that there is reasonable assurance that: (i) the activities authorized by the license can be conducted without endangering the health and safety of the public; and (ii) these activities will be conducted in compliance with the applicable regulations of 10 CFR part 70. The NRC has further determined that the issuance of the license is not inimical to the common defense and security.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," the details with respect to this action, including the final safety evaluation report and accompanying documentation and license, are available electronically in the ADAMS Public Documents collection at https://www.nrc.gov/reading-rm/adams.html.
