NUCLEAR REGULATORY COMMISSION
[Docket No. 70-7027; NRC-2022-0201]
TRISO-X, LLC; Special Nuclear Material License Application for
the TRISO-X Fuel Fabrication Facility; Final Environmental Impact
Statement
AGENCY: Nuclear Regulatory Commission.
ACTION: Notice; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) has issued a
final Environmental Impact Statement (EIS) for a Special Nuclear
Material License Application for the TRISO-X Fuel Fabrication Facility
(FFF). TRISO-X, LLC (TRISO-X) would be authorized to possess and use
special nuclear material to manufacture high-assay low enriched uranium
(HALEU) fuel. The proposed fuel fabrication facility would be located
on a 110-acre site at the Horizon Center in Oak Ridge, Roane County,
Tennessee.
DATES: The FEIS referenced in this document was made publicly available
on February 12, 2026.

SUPPLEMENTARY INFORMATION:
I. Background
In accordance with section 51.118 of title 10 of the Code of
Federal Regulations (10 CFR) ``Final environmental impact statement--
notice of availability,'' the NRC is providing notice that the final
EIS for a Special Nuclear Material License Application for the TRISO-X
FFF is available for public inspection. The NRC issued a draft EIS for
this action on September 26, 2025 (ADAMS Accession No. ML25267A128) and
published a Federal Register (FR) notice on October 23, 2025 (90 FR
48508) to request comments on the draft EIS. On November 17, 2025, the
NRC extended the public comment period for the draft EIS until December
8, 2025 (90 FR 51412). The final EIS includes responses to comments on
the draft EIS and conforming changes where appropriate.
II. Discussion
The NRC has prepared a final EIS as part of its environmental
review of the TRISO-X application for a 40-year license to possess and
use special nuclear material at a FFF that would be located on a 110-
acre greenfield site in Oak Ridge, Roane County, Tennessee. This final
EIS assesses the potential environmental impacts of the TRISO-X license
application and the associated proposal to construct, operate, and
decommission the FFF, as well as the no-action alternative to the
proposed action.
The proposed Federal action is the issuance of a license, under 10
CFR part 70, ``Domestic Licensing of Special Nuclear Material,'' to
authorize TRISO-X to possess and use special nuclear material to
manufacture HALEU fuel at a to-be-constructed FFF. The facility would
produce tri-structural isotropic-based coated particles and final fuel
forms using uranium enriched to less than 20 weight percent uranium-
235. Issuance of a license enabling the possession and use of special
nuclear material at the FFF would be for a first-of-its-kind
fabrication operation in the United States.
The final EIS for TRISO-X's license application includes the NRC
staff's analysis that evaluates the environmental impacts of the
proposed action and the no-action alternative to the proposed action.
The final EIS also contains the NRC staff's final recommendation on the
action to be taken, which is based on the following factors:
The NRC staff's review of TRISO-X's environmental report
(included as part of the TRISO-X license application) and associated
responses from TRISO-X to requests from the NRC staff for clarifying
information;
The NRC staff's review of comments received as part of the
scoping process;
The NRC staff's communications with Federal, State, and
local agencies, as well as Tribal officials;
The NRC staff's review of comments on the draft EIS; and
The NRC staff's independent environmental review.
The NRC staff's final recommendation, unless safety issues mandate
otherwise, is that the NRC issue the license to possess and use special
nuclear material to TRISO-X.
