If we needed more proof that this is a “nuclear week”—in the words of Energy Secretary Jennifer Granholm on Wednesday, as she announced small modular reactor funding while celebrating tech company investments in advanced reactors—the Department of Energy came through late yesterday when, just nine days after announcing six contracts for high-assay low-enriched uranium (HALEU) deconversion, it announced four contracts for HALEU enrichment services worth up to $2.7 billion. Those contracts are going to Centrus Energy’s American Centrifuge Operating subsidiary, General Matter, Orano Federal Services, and Urenco USA’s Louisiana Energy Services.

Uranium enricher Urenco welcomed representatives from the International Atomic Energy Agency to an August 19 event to mark the creation of an IAEA Centre of Excellence for Safeguards and Non-Proliferation at its Capenhurst, England, site. Representatives of the three nations with ownership stakes in Urenco—the United Kingdom, the Netherlands, and Germany—were joined by representatives from the United States, where Urenco also operates an enrichment plant. Urenco expects the new center to be fully operational in 2025.

The U.K. government this week announced a $245 million (£196 million) award to help Urenco build Europe’s first advanced reactor fuel manufacturing plant, which will be located in northwest England at the company’s Capenhurst site. Urenco, which is part-owned by the U.K. government, will cofund the project.

With all that is happening in the industry these days, the nuclear fuel supply chain is still a hot topic. The Russian assault in Ukraine continues to upend the “where” and “how” of attaining nuclear fuel—and it has also motivated U.S. legislators to act.

Two years into the Russian war with Ukraine, things are different. The Inflation Reduction Act was passed in 2022, authorizing $700 million in funding to support production of high-­assay low-enriched uranium in the United States. Meanwhile, the Department of Energy this January issued a $500 million request for proposals to stimulate new HALEU production. The Emergency National Security Supplemental Appropriations Act of 2024 includes $2.7 billion in funding for new uranium enrichment production. This funding was diverted from the Civil Nuclear Credits program and will only be released if there is a ban on importing Russian uranium into the United States—which could happen by the time this column is published, as legislation that bans Russian uranium has passed the House as of this writing and is headed for the Senate. Also being considered is legislation that would sanction Russian uranium. Alternatively, the Biden-Harris administration may choose to ban Russian uranium without legislation in order to obtain access to the $2.7 billion in funding.

The United States has an ambitious goal: to establish a high-assay low enriched-uranium advanced nuclear fuel supply chain, revive the once thriving nuclear fuel market for low-enriched uranium in the nation, and “reestablish U.S. leadership in nuclear energy more broadly.” Making a success of that could have impacts beyond the nuclear sector. According to the Department of Energy’s Office of Nuclear Energy, “Expanding domestic LEU and HALEU enrichment production will be essential for fueling the clean energy required to bring down emissions in all sectors of the economy—including in hard-to-abate sectors such as manufacturing and industrial—while delivering high paying jobs to communities across the country.”

On March 26, Silex Systems Ltd. announced that Global Laser Enrichment’s test loop pilot demonstration facility and operational safety programs have been reviewed by the Nuclear Regulatory Commission and approved for loading uranium hexafluoride feed material in preparation for the next phase of GLE’s enrichment technology demonstration in the second quarter of 2024.

Almost two-thirds of 14- to 18-year-olds in the United Kingdom would consider a career in nuclear if they knew more about it, according to a new report, Nuclear Energy: Young People’s Views on Nuclear Energy and Careers in the Nuclear Sector, from the British Science Association (BSA).

About the report: The report was conducted as part of the BSA’s Future Forum program and was funded by Urenco, an international supplier of uranium enrichment services and fuel cycle products, as part of its commitment to education and skills development.

The report centered around an initial survey of 1,000 14- to 18-year-olds in England, Scotland, and Wales, with two follow-up workshops that were attended by 39 young people, providing the opportunity for more detailed responses.

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.

The front end of the fuel cycle is getting a lot of attention lately—and it needs it. The war in Ukraine has disrupted the global supply chain for many products, nuclear fuel being one. Several countries have determined that they no longer want to rely on nuclear fuel from Russia. This can be anything from fabricated fuel including uranium, conversion, and enrichment to just enrichment.

Since the Cold War, Russia has been a major supplier of nuclear fuel to the West. Replacing Russia as the main supplier will take both time and money—a fact that has become even more clear as the small modular reactor community grows, and with it, the demand for high-assay low-enriched uranium (HALEU) for fuel.

The American Nuclear Society has been highlighting the immediacy of the fuel supply problem—which will become a crisis without immediate action—for years. In 2021, ANS wrote to Congress, urging swift action. This year, Nuclear News and ANS’s Nuclear Newswire have run a three-part series by energy writer and consultant Matt Wald on the domestic nuclear fuel shortage. The first article, “On the verge of a crisis: The U.S. nuclear fuel Gordian knot,” was published on Newswire on April 14; the second, “The U.S. nuclear fuel Gordian knot: From global supplier to vulnerable customer,” on May 19. The final piece of the series, “The U.S. nuclear fuel Gordian knot: The uncertain path forward,” was posted on September 1.

In the last few weeks of 2021, when it was clear that the Russian invasion of Ukraine had put this country’s uranium fuel supply in jeopardy, nuclear energy advocates lobbied hard to attach provisions to various pieces of “must-pass” legislation—such as the National Defense Appropriations Act (NDAA), the Ukraine Supplemental Appropriations Act, the Infrastructure Investment and Jobs Act, and the CHIPS and Science Act—to have the government get the ball rolling on new domestic uranium fuel production capacity. Four times they thought they had succeeded, that Congress was going to allocate enough money to start the United States on the road to a secure supply of reactor fuel, including the higher-enriched fuel needed for advanced reactors.

The U.K. government has announced its intention to provide a loan guarantee of £192 million (about $244 million) to enable Britain-based Urenco to supply Ukraine’s nuclear operator Energoatom with uranium enrichment services. (Urenco has been a supplier to Energoatom since 2009.) The loan is to be made through UK Export Finance, the nation’s export credit agency.

According to the August 23 announcement, the added support will “strengthen Ukraine’s energy security and further isolate Putin by helping the country maintain its independence from Russian nuclear fuel.” Once provided, the additional funds will boost the United Kingdom’s total nonmilitary assistance to Ukraine to nearly £5 billion (about $6.4 billion), the government stated.

The announcement came as Grant Shapps, U.K. secretary of state for energy security and net zero, visited Kyiv to meet with senior government ministers and leading energy figures—including Energoatom president Petro Kotin and Ukraine’s deputy prime minister Oleksandr Kubrakov and energy minister German Galushchenko—to discuss British support for Ukraine’s eventual recovery.

Promising a “massive revival of nuclear power,” the U.K. government yesterday officially launched Great British Nuclear—an “arms-length” governmental body established to help ramp up the nation’s nuclear capacity to as much as 24 GW by 2050. Alongside, the U.K. announced a GBN-managed small modular reactor competition.

Urenco announced July 6 that it will expand enrichment capacity at its U.S. site in Eunice, N.M.—known as UUSA—by adding new centrifuge cascades to increase capacity by about 700 metric tons of separative work units per year, or a 15 percent increase, with the first new cascades coming on line in 2025.

This article is the second in a series about the domestic nuclear fuel crisis. The first in the series, “‘On the verge of a crisis’: The U.S. nuclear fuel Gordian knot,” was published on Nuclear Newswire on April 14, 2023.

Once upon a time, enrichment was a government monopoly—at least outside the Soviet bloc. But the United States, eager to get out of the field, was convinced that the private sector could do it better. Now, the West is dependent on the Soviets’ successors and is facing an uncertain supply, a complication of the Russian invasion of Ukraine.

Slowly, a consensus is growing that dependence on imports is a bad idea. Some experts also say that upsets like the 2011 Tōhoku earthquake and tsunami, and the collapse of natural gas prices due to fracking, show that the market is too prone to shocks for private companies to navigate without support. One of the architects of the U.S. government’s exit from the enrichment game is now voicing second thoughts. And belatedly—shortly after the first anniversary of the beginning of the Russian invasion—five Western countries, including the United States, announced that they have to get more deeply involved in the fuel supply chain, but didn’t say precisely how.

Canada’s Cameco and U.K.-based Urenco last week jointly announced the signing of agreements to become part of a Westinghouse-led fuel supply chain for Bulgaria’s Kozloduy nuclear power plant. (Also included in the partnership is Uranium Asset Management.)

The naturalist John Muir is widely quoted as saying, “When we try to pick out anything by itself, we find it hitched to everything else in the Universe.” While he was speaking of ecology, he might as well have been talking about nuclear fuel.

At the moment, by most accounts, nuclear fuel is in crisis for a lot of reasons that weave together like a Gordian knot. Today, despite decades of assertions from nuclear energy supporters that the supply of uranium is secure and will last much longer than fossil fuels, the West is in a blind alley. We find ourselves in conflict with Russia with ominous implications for uranium, for which Russia holds about a 14 percent share of the global market, and for two processes that prepare uranium for fabrication into reactor fuel: conversion (for which Russia has a 27 percent share) and enrichment (a 39 percent share).

Whether commercial demand for high-assay low-enriched uranium (HALEU) fuel ultimately falls at the high or low end of divergent forecasts, one thing is certain: the United States is not ready to meet demand, because it currently has no domestic HALEU enrichment capacity. But conversations happening now could help build the commercial HALEU enrichment infrastructure needed to support advanced reactor deployments. At the 2022 American Nuclear Society Winter Meeting, representatives from three potential HALEU enrichers, the government, and industry met to discuss their timelines and challenges during “Got Fuel? Progress Toward Establishing a Domestic US HALEU Supply,” a November 15 executive session cosponsored by the Nuclear Nonproliferation Policy Division and the Fuel Cycle and Waste Management Division.

The nuclear industry leaders assembled in Washington, D.C., last week to discuss small modular reactor supply chains agreed that lost generation capacity from the expected retirement of hundreds or thousands of coal power plants over the next decade—a cliff, in one panelist’s words—represents an opportunity that developers of SMRs and advanced reactors are competing to meet.

“I think in total 80 projects are ongoing,” said Boris Schucht, panel moderator and chief executive officer of Urenco Group, as he opened the forum. “Of course not all of them will win, and we will discuss today what is needed so that they can be successful.”

For years, pressure has been building for a commercial path to a stable supply of high-assay low-enriched uranium (HALEU)—deemed essential for the deployment of advanced power reactors—but advanced reactor developers and enrichment companies are still watching and waiting. In contrast, the uranium spot price soared after Sprott Physical Uranium Trust, a Canadian investment fund formed in July, began buying up U3O8 supplies, causing the price to increase over 60 percent, topping $50 per pound for the first time since 2012. Fueled by growing acknowledgment that nuclear power is a necessary part of a clean energy future, uranium is the focus of attention from Wall Street to Capitol Hill.

To nuclear fuel suppliers, today’s operating reactors represent a defined customer base with predictable demands. Utilities must order their next fuel reload far in advance of an outage; enrichers and fabricators work to fill those orders. Adapting such a highly optimized supply chain to accommodate new products—fuels with new materials, claddings, and higher enrichments and burnups—will require alignment between all parties involved to meet the associated research, enrichment, manufacturing, regulatory, transportation, and operating experience needs.

That was the consensus during “Current Accident Tolerant Fuel Environment,” a technical session held on March 9 during the Nuclear Regulatory Commission's four-day Regulatory Information Conference (RIC, March 8-11). The session was chaired by NRC Chairman Christopher Hanson, who was taking part in his first RIC as a member of the commission.
