The United Kingdom’s Department for Energy Security and Net Zero announced plans on January 7 to invest £300 million (about $383 million) to build a high-assay low-enriched uranium (HALEU) enrichment facility in northwest England. The goal? To “end Russia’s reign as the only commercial producer of HALEU.” Britain is now the first European country to declare that it will begin HALEU enrichment in a bid for supply chain security.

The Department of Energy issued a final request for proposals (RFP) on January 9 for uranium enrichment services to help establish a commercial domestic supply of high-assay low-enriched uranium (HALEU) to fuel a potential fleet of advanced reactors. Without HALEU, advanced reactors will not be able to proceed past the demonstration stage. And given the investments of capital and time required to license and build a nuclear power plant—even a smaller, more efficient advanced reactor—eliminating fuel uncertainty could be what a utility needs to invest in new construction.

Investors continue to be bullish on uranium, according to a number of recent news reports. Stockhead recently trumpeted, “Uranium has started 2024 the same way it ended 2023—like a bull in a china shop. Spot prices are now agonizingly close to US$100/lb for the first time since 2008, with term pricing not far behind.” Similarly, Mining.com noted, “The spot price of uranium continues to rise, boosted by pledges to triple nuclear power by mid-century, supply hiccups from producers such as Cameco . . . , and the looming threat of a ban on Russian exports to the West.”

Leaders of five nations that collectively represent 50 percent of the world’s uranium conversion and enrichment capacity—the United States, Canada, Japan, France, and the United Kingdom—are making a habit of meeting on the sidelines of global climate talks to pledge their commitment to securing the nuclear fuel supply chain. On December 7 at the Net Zero Nuclear Summit—an event held in Dubai, United Arab Emirates, during the UN Climate Change Conference, or COP28—representatives of those nations announced plans to “mobilize at least $4.2 billion” in government and private investment in enrichment and conversion capacity. The commitment expands on an initial civil nuclear fuel security agreement that the so-called Sapporo 5 reached in April 2023, when they met (as now, on the sidelines) during a G7 Ministers’ Meeting on Climate, Energy, and Environment in Sapporo, Japan.

Nuclear fuel companies Lightbridge Corporation and Centrus Energy have announced a contract to conduct a front-end engineering and design (FEED) study to add a dedicated Lightbridge Pilot Fuel Fabrication Facility (LPFFF) at Centrus’s American Centrifuge Plant in Piketon, Ohio.

Lightbridge chief executive officer Seth Grae and Centrus CEO Daniel Poneman inked the agreement yesterday at the COP28 conference, currently underway in the United Arab Emirates.

The FEED study, according to the joint announcement, will identify infrastructure and licensing requirements as well as the estimated cost and construction schedule for the LPFFF. Centrus’s wholly owned subsidiary, American Centrifuge Operating, will lead the study, which is expected to be completed sometime next year.

At the World Nuclear Exhibition in Paris this week, Ontario Power Generation announced contracts with Canadian, French, and U.S. companies to ensure a fuel supply for the first of four GE Hitachi Nuclear Energy BWRX-300 small modular reactors planned for deployment at OPG’s Darlington nuclear power plant.

TerraPower and Uranium Energy announced today that they have signed a memorandum of understanding to “explore the potential supply of uranium” for TerraPower’s demonstration reactor in Kemmerer, Wyo.

Framatome Inc. and Ultra Safe Nuclear Corp. (USNC) signed an agreement on November 28 at the World Nuclear Exhibition in Paris, France, establishing a joint venture to manufacture nuclear fuel for USNC’s gas-cooled microreactor and other advanced reactor designs. Working together, the companies plan to produce commercial quantities of TRISO fuel particles and USNC’s proprietary Fully Ceramic Microencapsulated (FCM) fuel, which contains TRISO fuel particles within a ceramic fuel pellet.

The Department of Energy plans to award one or more contracts to deconvert high-assay low-enriched uranium (HALEU) from its post-enrichment gaseous uranium hexafluoride (UF₆) state to other chemical forms, such as metal or oxide. The DOE’s final request for proposals (RFP) for deconversion services was issued November 28 as one part of the agency’s effort—under the HALEU Availability Program—to establish a reliable domestic supply of advanced reactor fuel. The DOE will store the deconverted material until it is required by a fuel fabricator or other end user.

Researchers at Idaho National Laboratory in early 2023 manufactured commercial-grade high-assay low-enriched uranium (HALEU) fuel pellets to the specifications of a General Electric accident tolerant fuel design, INL announced November 21. A team working at INL’s Experimental Fuels Facility at the Material and Fuels Complex fabricated about two dozen uranium dioxide pellets using HALEU enriched up to 15 percent U-235.

Centrus Energy and the Department of Energy announced November 7 that Centrus has produced 20 kilograms of HALEU at the DOE-owned American Centrifuge Plant in Piketon, Ohio, satisfying Phase One of a DOE contract to stand up and operate 16 advanced centrifuges. Centrus will now move on to Phase Two of the contract, which requires a full year of HALEU production at a rate of 900 kilograms per year.

Just a few hours after a new Speaker of the House of Representatives was elected on October 25, the White House sent a list of funding priorities for “critical domestic needs” to Congress for consideration as legislators restart the stalled annual appropriations process. Those priorities include $2.2 billion for low-enriched uranium (LEU) and high-assay low-enriched uranium (HALEU) enrichment capabilities. And to ensure that investment in domestic HALEU enrichment pays off, the White House is also calling for a long-term ban on enriched uranium from Russia.

Westinghouse has signed a contract with Rolls-Royce SMR to develop a fuel design for the British firm’s small modular reactor program, the companies announced last week.

The design work, to be undertaken in the United Kingdom and the United States, will include associated core components and will be based on an existing Westinghouse pressurized water reactor fuel assembly design.

American Centrifuge Operating (ACO), a subsidiary of Centrus Energy, has started enriching uranium hexafluoride gas to high-assay low-enriched uranium (HALEU) levels at the Department of Energy’s enrichment facility in Piketon, Ohio, the DOE announced October 11. The HALEU will be used to help fuel the initial cores of two demonstration reactors awarded under DOE’s Advanced Reactor Demonstration Program and will also support fuel qualification and the testing of other new advanced reactor designs.

Penn State’s Radiation Science and Engineering Center (RSEC) has received the first new TRIGA fuel shipped to the United States since 2012, the university announced on September 28. The fuel reached University Park, Pa., on September 27 and is destined for RSEC’s Breazeale Reactor, the nation’s longest continuously operating university research reactor.

Southern Nuclear last Friday announced that its Vogtle Unit 2 reactor has become the first U.S. commercial reactor to be authorized by the Nuclear Regulatory Commission to use accident tolerant fuel exceeding 5 percent uranium-235 enrichment.

The Nuclear Regulatory Commission is requesting comments on the regulatory basis for a proposed rule for light water reactor fuel designs featuring high-assay low-enriched uranium (HALEU), including accident tolerant fuel (ATF) designs, and on draft guidance for the environmental evaluation of ATFs containing uranium enriched up to 8 percent U-235. Some of the HALEU feedstock for those LWR fuels and for advanced reactor fuels could be produced within the first Category II fuel facility licensed by the NRC—Centrus Energy’s American Centrifuge Plant in Piketon, Ohio. On September 21, the NRC approved the start of enrichment operations in the plant’s modest 16-machine HALEU demonstration cascade.

As a student, I had the opportunity to tour Urenco USA in Eunice, N.M.—the only commercially operated uranium enrichment facility in the United States. Seeing a fuel cycle facility for the first time and learning about the centrifugal technology used to separate U-235 from U-238 was enriching (pun intended). In the nuclear utility sector, where I am currently working as a core design engineer, the focus is on creating safe, reliable, carbon-free nuclear energy; too often, however, we miss out on other key players in the nuclear fuel cycle.

As a visiting student, I listened to the introductions, the tour guides, the operators, and the engineers at Urenco, and I was hooked. It was so different from what I learned in college about commercial reactors. I was so fascinated with how Urenco operated and their role in the nuclear industry that I started my career there in 2016. The company did an incredible job educating their personnel not only on their processes but also on the work of other fuel cycle facilities (mining, conversion, and fabrication, to name a few).

For decades, more energy has meant more fuel: fossil fuels.

But nuclear fuel—unlike coal, oil, or even natural uranium—is a feat of engineering, not a commodity extracted from the earth. Now, “more” means more engineering—to boost uranium density or to close the fuel cycle.

Multiple market forces on nuclear fuel have arisen seemingly at the same time since the Russian war in Ukraine started. Accident tolerant fuels (ATF), lead test rods, and lead test assemblies have had their first shot in real operating conditions, in recent cycles. But the popularity of their so-called accident tolerance has nothing to do with accidents, since any practical nuclear professional knows that the safety of nuclear energy is already higher than that of any other electricity generation source. The popularity comes down to fuel performance. Are we on the cusp of a revolution in nuclear fuel performance under the guise of accident tolerance?
