NUCLEAR REGULATORY COMMISSION

[Docket No. 70-7027; NRC-2022-0209]


TRISO-X, LLC; Special Nuclear Material License for the TRISO-X 
Fuel Fabrication Facility

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice; issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) has issued 
Special Nuclear Material (SNM) License No. SNM-7007 to TRISO-X, LLC 
(TRISO-X) to operate the TRISO-X Fuel Fabrication Facility as proposed 
in its license application and to possess and use SNM to manufacture 
high-assay low enriched uranium (HALEU) fuel in Oak Ridge, Roane 
County, Tennessee. TRISO-X will be required to operate under the 
conditions listed in Materials License No. SNM-7007. The NRC staff 
published a record of decision (ROD) that supports the NRC's decision 
to approve TRISO-X's license application for the fuel fabrication 
facility and to issue the license.

DATES: 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,

[[Page 12628]]

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. From this site, you can 
access ADAMS, which provides text and image files for the NRC public 
documents.
