The Nuclear Regulatory Commission has extended its comment period on the draft environmental impact statement for TRISO-X’s special nuclear material license application for its proposed fuel fabrication facility in Oak Ridge, Tenn.
Public comments on the draft environmental review were initially due by Nov. 17, but will now be due on Dec. 8, according to a Monday notice posted in the Federal Register.
NRC attributed the extension to time lost due to the government shutdown.
“The NRC registered the draft EIS with the U.S. Environmental Protection Agency (EPA) in September 2025,” according to the notice. “However, due to the lapse of government appropriations, notice of the availability of the document was not published on October 3, 2025, by EPA as originally scheduled.”
NRC posted a Federal Register notice on Oct. 23 for the TRISO-X’s draft environmental impact statement but said NRC staff will extend the period, to be in compliance with regulatory requirements.
TRISO-X, an X-Energy subsidiary, is seeking a license authorizing it to obtain and use special nuclear material to manufacture high-assay low-enriched uranium (HALEU) fuel.
