Standard Nuclear expects to begin operations at its new Tennessee and Idaho TRISO fuel production facilities by the end of 2026. These sites will utilize a modular manufacturing framework to reach a combined annual capacity of 5 metric tons of uranium. This expansion increases domestic HALEU fuel supply for power reactors and government space and defense programs.

Nuclear fuel manufacturer Standard Nuclear is describing "construction and regulatory approval milestones" for two TRISO fuel production facilities that are both under construction. The company reports that construction is "substantially complete" for both the SN-TN (in Tennessee) and SN-ID (in Idaho) sites and that the Department of Energy has...

Standard Nuclear is participating in the DOE's Fuel Line Pilot Program and Surplus Plutonium Utilization Program, and is also among the companies receiving HALEU from the DOE for use in their fuel production or reactor programs.

Opening soon: Standard Nuclear says the identical SN-TN and SN-ID facilities are expected to come on line before the end of the year, with startup, commissioning, and licensing activities continuing over the rest of the summer. Under DOE authorization facilitated by the Fuel Line Pilot Program, each facility could initially produce as much as 1 metric ton of uranium (MTU) of TRISO annually and scale up over time to a collective total of 5 MTU per year.
