X-energy has announced that its wholly owned subsidiary, TRISO-X, plans to build the TRISO-X Fuel Fabrication Facility, dubbed TF3, at the Horizon Center Industrial Park in Oak Ridge, Tenn. X-energy has produced kilogram quantities of fuel at its pilot plant at Oak Ridge National Laboratory through a public-private partnership.

The commercial plant will use high-assay low-enriched uranium (HALEU) to produce TRISO particles, which are fabricated into fuel forms, including the spherical graphite “pebbles” needed to fuel the company’s Xe-100 high-temperature gas reactor. Site preparation and construction are expected to get underway in 2022, and commissioning and start-up are scheduled for as early as 2025, according to X-energy.

ANS webinar looked at building domestic HALEU production capacity

March 16, 2022, 12:00PMANS News

The United States must ramp up the domestic production of high-assay low-enriched uranium (HALEU), the panelists agreed during a March 11 members-only webinar held amid heightened concerns about energy security following Russia’s invasion of Ukraine, and the day after Congress approved $45 million for the HALEU Availability Program for fiscal year 2022.

John Starkey, ANS director of public policy, moderated the webinar, which featured panelists Scott Kopple, senior director of government relations at BWX Technologies; Everett Redmond, senior technical advisor at the Nuclear Energy Institute; Benjamin Reinke, senior director of corporate strategy and advisor to the CEO at X-energy; Patrick White, project manager at the Nuclear Innovation Alliance (NIA); and Brad Williams, a member of the Senate Energy and Natural Resources Committee staff.

A recording of the webinar is available to ANS members.

The need for a metallic nuclear fuels qualification plan

February 4, 2022, 3:13PMNuclear NewsHank Hogan, Steven Hayes, Nicolas Woolstenhulme, and Colby Jensen

Positioning nuclear power to combat climate change requires the rollout of advanced reactors to replace carbon-­emitting power generation. That necessity, and its urgency, is reflected in recent budget proposals for the Department of Energy’s Office of Nuclear Energy. Part of that proposed funding focuses on deploying new fuel technologies.

Metallic fuels, which are alloys of fissionable material, offer several advantages, including more fuel-­efficient reactors with a double or greater fuel burnup than the oxide fuels found in light water reactors. Fuel fabrication is also more cost-­effective with metallic fuels than with oxide fuels. Furthermore, much of the research and development effort needed to qualify these metallic fuels has been done.

Advanced reactors: Now comes the hard part

January 28, 2022, 2:26PMNuclear NewsMatthew L. Wald

Designing a reactor is complicated but building one may be harder. Even companies that have had lots of practice haven’t always done it well. And all the power reactors in service today were built by companies that had years of experience in other kinds of big steam-electric power plants. In contrast, some of the creative new designs now moving toward commercialization come from start-ups that have never built anything at all. How should they prepare?
