The 214,000-square-foot structure is now ready for the next phase: interior fit-out, installation of production equipment, and completion of supporting infrastructure.<\/p>\n<p>TX-1 is set to become the first commercially built advanced nuclear fuel fabrication facility constructed in the United States in over fifty years. Once fully operational, it will produce approximately 700,000 <strong>TRISO-X<\/strong> fuel pebbles per year \u2014 equivalent to five metric tons of uranium \u2014 with enough capacity to fuel up to eleven <strong>Xe-100<\/strong> reactors. TRISO-X fuel consists of small uranium kernels encapsulated in three layers of ceramic and carbon materials, then embedded in spherical fuel elements. The fuel&#8217;s geometry builds safety directly into the material physics: in the event of a thermal anomaly, heat dissipates passively, with no need for active cooling systems.<\/p>\n<p>Reaching this construction milestone required navigating a significant regulatory journey. The U.S. <strong>Nuclear Regulatory Commission<\/strong> issued TRISO-X a forty-year special nuclear material license \u2014 the first NRC Category 2 license ever granted for the processing of High-Assay Low-Enriched Uranium, known as <strong>HALEU<\/strong>. This type of uranium, enriched between 5% and 20% in U-235, is essential for next-generation advanced reactors. Its large-scale commercial production on American soil has long been a missing link in the domestic nuclear fuel supply chain.<\/p>\n<p>The first planned use of fuel produced at TX-1 is tied to X-energy&#8217;s project at <strong>Dow Inc.<\/strong>&#8216;s industrial site in Seadrift, Texas, where four Xe-100 reactors rated at 80 MW each are planned. The NRC approved the environmental review for that project in May. X-energy is also advancing the <strong>Cascade Advanced Energy<\/strong> program in Washington State, in partnership with <strong>Energy Northwest<\/strong> and Amazon. Last July, the State of Tennessee awarded the company an $11 million grant to support development of the fuel fabrication campus.<\/p>\n<p>Joel Duling, President of TRISO-X, described the transition from exterior construction to interior equipment installation as a concrete shift toward actual production. Each milestone, in his words, brings the creation of a domestic source of advanced nuclear fuel \u2014 capable of sustaining America&#8217;s next-generation reactors \u2014 one step closer to reality. The broader project also includes a second facility, TX-2, with the stated goal of closing a structural gap in the nuclear fuel supply chain for the United States and its allies. If timelines hold, TX-1 could begin commercial production before the end of the decade, making industrially available for the first time a fuel that has for decades remained confined to the realm of research.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>X-energy has announced the completion of vertical construction on TX-1, the first commercial advanced nuclear fuel fabrication facility in the United States, located in Oak Ridge, Tennessee.
