X-energy, DOW to collaborate on SMR deployment

August 9, 2022, 12:27PMNuclear News

Small modular reactor developer X-energy and materials science giant Dow this morning announced the signing of a letter of intent aimed at deploying X-energy’s Xe-100 reactor technology at one of Dow’s U.S. Gulf Coast facilities. The companies expect the SMR plant, which would provide power and process heat to the Dow facility, to be operational by approximately 2030.

Dow is the first manufacturer to declare its intention to develop SMR technology options and intends to take a minority equity stake in X-energy, according to the announcement.

News of the collaboration broke at the American Nuclear Society’s Utility Working Conference and Vendor Technology Expo, being held through August 10 at Marco Island, Fla.

U.K. nuclear services company Cavendish Nuclear has signed a memorandum of understanding with U.S. reactor and fuel-design engineering firm X-energy to act as its deployment partner for high-temperature, gas-cooled reactors (HTGRs) in the United Kingdom.

Headquartered in Rockville, Md., X-energy is the developer of the Xe-100, an 80-MWe reactor with a modular design permitting it to be scaled into a “four-pack” 320-MWe power plant. As a pebble bed HTGR, the Xe-100 would use TRISO particles encased in graphite pebbles as the fuel and helium as the coolant.

According to a May 11 joint statement from the companies, development and deployment of HTGRs in the United Kingdom would support an increase in the nation’s energy security, contribute toward the government’s net-zero-by-2050 commitment, and create considerable opportunities for the U.K. nuclear supply chain.

The Department of Defense’s Strategic Capabilities Office (SCO) on April 13 released a record of decision (ROD) for Project Pele, a program intended to design and build a mobile microreactor at Idaho National Laboratory. The ROD for Project Pele is based on a final environmental impact statement (EIS) published in February. The designs submitted by the two candidate vendors—BWXT Advanced Technologies and X-energy—both fit the parameters analyzed in the final EIS.

The University of Illinois at Urbana-Champaign formed a partnership with Ultra Safe Nuclear Corporation to deploy an advanced research reactor on campus, based on a microreactor design that improves upon well-established high-temperature, gas-cooled reactor (HTGR) technology. Unlike traditional research reactors, our focus at UIUC is not on a laboratory tool to study radiation interactions with matter, or even on the production of radioisotopes. Instead, we will build a research, education, and training facility intended to help advanced reactor technology become a widely deployable, marketable, economic, safe, and reliable option for a clean energy future. If successful, the USNC-designed Micro Modular Reactor (MMR)a would operate on UIUC’s campus with the capability to advance critical and enabling technologies required for advanced reactors to realize their full potential, while educating and training the workforce as a key step toward delivering on the technology’s promise. Microreactors can become a transformative distributed energy technology and revolutionize energy infrastructure worldwide.

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.

NN Asks: What fuels your commitment to nuclear technology?

February 8, 2022, 12:00PMNuclear NewsKelly Hartless

When I came to work at BWX Technologies immediately after getting my degree in chemical engineering from the University of Virginia, I was amazed to see how nuclear energy could be harnessed to both power and protect our country. Since then, I’ve come to see that nuclear energy can do even more. The nuclear industry’s next tasks are to address climate change, propel us to other bodies in the solar system, and provide power when we arrive. Recently developed coated fuels are an enabling technology for these tasks.

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.

Nuclear thermal propulsion (NTP) is one technology that could propel a spacecraft to Mars and back, using thermal energy from a reactor to heat an onboard hydrogen propellant. While NTP is not a new concept, fuels and reactor concepts that can withstand the extremely high temperatures and corrosive conditions experienced in the engine during spaceflight are being designed now.

BWX Technologies announced on December 13 that it has delivered coated reactor fuels to NASA for testing in support of the Space Technology Mission Directorate’s NTP project. BWXT is developing two fuel forms that could support a reactor ground demonstration by the late 2020s, as well as a third, more advanced and energy-dense fuel for potential future evaluation. BWXT has produced a videoof workers processing fuel kernels in a glovebox.

Nuclear fuel considerations in the development of advanced reactors

December 8, 2021, 12:04PMNuclear NewsGary Mignogna


The world faces an urgent need to decarbonize and expand clean energy systems. Earlier this year, the United States announced goals to achieve a 100 percent clean electricity grid by 2035 and net-zero emissions across the entire economy by 2050. Today, nuclear energy plants provide more than 50 percent of the United States’ carbon-free energy. Existing plants, along with the advanced technologies currently being developed and demonstrated, are crucial to the United States’ and the world’s clean energy future.

Technologies such as advanced non-light water reactors, which have higher operating temperatures than today’s light water reactors, will be vital to meeting economy-wide decarbonization goals. For example, process heat applications and chemical and synthetic fuel production require higher temperatures and currently rely on fossil fuels. Advanced reactors are the only carbon-free technologies that can provide the high temperatures these processes need.
