The Department of Energy’s Office of Clean Energy Demonstrations issued a draft environmental assessment (EA) in early November for a test and fill facility (TFF) that TerraPower plans to build in Kemmerer, Wyo.—the town selected two years ago to host the company’s first Natrium sodium fast reactor. The draft EA, open for comment through December 1, describes TerraPower’s plans to construct a nonnuclear facility that would safely store about 400,000 gallons of sodium to test coolant system designs and ultimately fill the planned reactor.

Dow and X-energy have announced the location of their Xe-100 small modular reactor deployment project: Dow’s UCC Seadrift Operations manufacturing site in Texas. According to a May 11 joint news release, the SMR plant will provide the Seadrift site with power and heat as the site’s existing energy and steam assets near the end of their operational lives.

Dow and X-energy announced today that they have signed a joint development agreement (JDA) to demonstrate the first grid-scale advanced nuclear reactor at an industrial site in North America within a decade. As part of the agreement, Dow is now a subawardee under X-energy’s Advanced Reactor Demonstration Program (ARDP) Cooperative Agreement with the Department of Energy.

The Nuclear Regulatory Commission recently presented its proposed 30-month licensing review timeline of TRISO-X’s planned fuel fabrication facility at the project’s first-ever public meeting in Oak Ridge, Tenn.
TRISO-X, a subsidiary of X-energy, has requested a 40-year license to possess and use special nuclear material to manufacture advanced fuel. The facility would be the first-ever commercial-scale fuel fabrication plant focused on using high-assay low-enriched uranium (HALEU).

The Department of Energy’s commitment to breaking down market barriers with initiatives, programs, and access to facilities is making it simpler and more efficient than ever for industry to partner with national laboratories. It is especially timely, as the country continues to face evolving security, economic, and clean energy challenges. Partnering opportunities via the DOE’s Cooperative Research and Development Agreements (CRADAs) and Strategic Partnership Projects (SPPs) are particularly prevalent in the commercial nuclear community and have seen a tremendous amount of funding and support dedicated to advancing the development, demonstration, and deployment of new reactor technologies.

Global Nuclear Fuel–Americas (GNF-A) and TerraPower announced their plans to build a Natrium fuel fabrication facility next to GNF-A’s existing fuel plant near Wilmington, N.C, on October 21. While more than 50 years of fuel fabrication at the site have supported the boiling water reactor designs of GE (GNF-A’s majority owner) and GE Hitachi Nuclear Energy (GEH), the Natrium Fuel Facility will produce metallic high-assay low-enriched uranium (HALEU) fuel for the sodium fast reactor—Natrium—that TerraPower is developing with GEH.

Another piece of the plan for meeting the urgent need for high-assay low-enriched uranium (HALEU) to fuel advanced reactor deployments fell into place when the Department of Energy held an Industry Day on October 14. Attendees were asked how soon they could deliver 25 metric tons per year of HALEU enriched in the United States from newly mined uranium. Offtake contracts for six or more years of HALEU production at that rate could be used to stock a DOE-owned HALEU bank to “support [HALEU] availability for civilian domestic research, development, demonstration, and commercial use.”

Leaders of X-energy and its TRISO-X subsidiary gathered on October 13 to break ground at the site of what X-energy bills as “North America’s first commercial-scale advanced nuclear fuel facility” in Oak Ridge, Tenn. X-energy expects the TRISO-X Fuel Fabrication Facility (TF3) to create more than 400 jobs and to be commissioned and operational by 2025.
