TRISO-X Fuel Fabrication
Overview
First commercial-scale TRISO fuel fabrication facility in the United States, being built in Oak Ridge, Tennessee.
TX-1 in Oak Ridge, Tennessee is in vertical construction and on schedule for completion in the first half of 2028. In February 2026 TRISO-X received the first-ever Part 70 HALEU fuel-fabrication license — an initial 40-year NRC license covering TX-1 and TX-2 — and TRISO-X pebble fuel is undergoing irradiation testing at Idaho National Laboratory. In July 2026 an $11M Tennessee state grant backed a planned expansion of the campus to add a second commercial facility (TX-2) and an R&D center (TX-L); together the three are designed to fuel about 55 Xe-100 reactors, making it one of the world's largest commercial-scale nuclear fuel campuses.
