X-Energy Unit Completes Vertical Construction of TX-1 Nuclear Fuel Facility in Tennessee

07:58 AM EDT, 09/24/2026 (MT Newswires) -- X-Energy's (XE) subsidiary TRISO-X completed construction of the 214,000-square-foot building structure at its TX-1 nuclear fuel fabrication facility in Oak Ridge, Tennessee, the company said Thursday. TRISO-X said the project will now move into the next phase of interior buildout and installation of fuel fabrication systems, equipment, and supporting infrastructure to prepare the facility for commercial operations. Once operational, TX-1 is expected to produce approximately 700,000 TRISO-X fuel pebbles per year, equivalent to 5 metric tons of uranium, with capacity to supply up to 11 Xe-100 reactors, the company said. TRISO-X said the US Nuclear Regulatory Commission granted the facility a 40-year Special Nuclear Material License earlier this year. Shares of X-Energy fell more than 1.2% in pre-bell activity on Thursday.
