The Department of Energy released an anticipated request for proposals on June 27 for low-enriched uranium enrichment. “Today’s action will help spur the safe and responsible build-out of uranium enrichment capacity in the United States, promote diversity in the market, and provide a reliable supply of commercial nuclear fuel to support the energy security and resilience of the American people and domestic industries, free from Russian influence,” the DOE declared.

A subcommittee markup of the House energy and water fiscal year 2025 appropriations bill is scheduled for 8:30 a.m. (EDT) today. The appropriations package would fund energy and water development and related agencies through Sept. 30, 2025.

“I’m proud that [the bill] continues to build off the work of our FY 2024 bill to strengthen America’s strategic nuclear stockpile, revitalize our ability to enrich uranium domestically, invest in our long-term energy security, and maintain our country’s ports and inland waterways,” said Rep. Chuck Fleischmann (R., Tenn.), chair of the energy subcommittee.

Las Vegas, Nev. — The American Nuclear Society (ANS) issued the following statement during the 2024 ANS Annual Conference in Las Vegas:

“The American Nuclear Society applauds the Group of Seven (G7) leaders’ Apulia communiqué in its call for continued international cooperation in strengthening, expanding, and diversifying civil nuclear supply chains as the world deploys advanced reactors.

The technical session “HALEU and Nonproliferation” on Tuesday at the American Nuclear Society Annual Conference focused on why increased nuclear fuel enrichment comes with increased responsibility. Reactor designers are pursuing high-assay low-enriched uranium fuel for their advanced designs, and technical and policy questions surrounding nuclear nonproliferation will need to be addressed if the United States is to become a HALEU supplier.

As small modular reactor (SMR) and advanced reactor (AR) developers look to build out their supply chains, NAC International (NAC) offers these companies a wide range of products and services for the full range of their nuclear energy facilities.

TerraPower announced May 29 that it will work with Framatome North America to fund the high-assay low-enriched uranium (HALEU) metallization pilot plant that Framatome is building at its fuel fabrication facility in Richland, Wash. A successful demonstration of Framatome’s capability of converting enriched uranium oxide to HALEU metal will “support the development of the domestic HALEU supply chain,” both companies say.

On May 13, President Biden signed the Prohibiting Russian Uranium Imports Act, unlocking the $2.72 billion that Congress conditionally appropriated in March to increase production of low-enriched uranium (LEU) and high-assay low-enriched uranium (HALEU).

High-assay low-enriched uranium (HALEU) has emerged as a popular fuel choice for advanced small modular reactors due to its long power production periods before refueling. It is currently being pursued by TerraPower, X-energy, BWX Technologies, Kairos, Oklo, and other reactor companies. HALEU has a uranium-235 enrichment ranging from 5 percent to 20 percent, whereas traditional LWRs use low-enriched uranium fuel enriched up to 5 percent.

HALEU will provide power for longer durations, compared with traditional LWRs. But could it also provide an opportunity for more rapid proliferation, as is speculated in a 2023 National Academy of Sciences report on advanced nuclear reactors (nap.nationalacademies.org/catalog/26630/)?

If a nuclear proliferator conspires to divert fresh nuclear fuel for weapons production when it has not been used in a reactor, the effort required in separative work units (SWUs) to enrich U-235 from 5 percent to 90 percent and that required to enrich from 20 percent to 90 percent are both very small, compared with the effort required to enrich U-235 from its natural abundance to the initial 5 percent.

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.

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.

There have been significant changes in the outlook for the existing U.S. nuclear fleet in the last few years. In 2021, we were looking at the early closure of units and could not even think of license extension. Since then, the combination of the U.S. government recognizing the clean-air benefits of nuclear and the impact of the war in Ukraine has resulted in a lot of positive activity on Capitol Hill for nuclear.

Several pieces of legislation have been passed in support of nuclear as law- and policymakers have recognized the important role nuclear power can play in achieving the nation’s clean-air goals. New legislation also is supporting reducing reliance on Russia for uranium enrichment by supporting the domestic production of high-assay low-enriched uranium (HALEU).

The Civil Nuclear Credit (CNC) Program, which was part of the 2021 Infrastructure Investment and Jobs Act, included $6 billion to prevent premature retirement of existing zero-carbon nuclear plants. On January 17, the Department of Energy awarded Diablo Canyon $1.1 billion from the CNC Program to support continued operations of the plant.

New appropriations bills currently under review in the U.S. Congress include a significant funding boost for nuclear energy.

This week, ranking members of both the U.S. House and Senate released six fiscal year 2024 appropriations, including the Energy and Water Development and Related Agencies bill that has nuclear energy funding for FY 2024.

The Department of Energy yesterday announced a draft environmental impact statement (EIS) on HALEU Availability Program plans to purchase high-assay low-enriched uranium under 10-year contracts to seed the development of a sustainable commercial HALEU supply chain.

Wesoff

According to an admittedly informal and unscientific survey of people from online “nuclear affinity groups” conducted by Eric Wesoff, the editorial director for clean energy newsroom Canary Media, there is no consensus regarding when the next nuclear power plant will come on line in the United States. Wesoff recently reported that upon polling his nuclear-connected network on LinkedIn, X, and Reddit, he found that “the responses were all over the map.”

Nuclear renaissance? Wesoff was prompted to try his survey about the expected date for the next nuclear plant because “conditions are perfect for the American nuclear renaissance.” He cited strong support for the nuclear industry from the Department of Energy as well as from public opinion polls and online “influencers.” He thought therefore that he would find confident predictions for when the next new U.S. reactor would go on line. Instead, he found uncertainty and varied responses.

Crownhart

“I’ve got nuclear power on the brain this week.” So writes climate and energy reporter Casey Crownhart in a recent edition the Spark, the MIT Technology Review’s climate newsletter. In her article, Crownhart describes how, while she was conducting research on advanced nuclear energy for another article, she “went down some rabbit holes on . . . potential options for future nuclear plants” and has “reached new levels of obsession” about nuclear energy.

Nuclear primer: Crownhart’s article could serve as a primer for both basic nuclear and advanced nuclear technologies. She begins by discussing the “two absolutely essential pieces” of conventional nuclear power plants—namely, the enriched uranium fuel and the pressurized water cooling system—and explains that the cooling system “keeps the whole thing from getting too hot and causing problems.”

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 United Kingdom released plans yesterday for the biggest expansion of nuclear power in 70 years. Officials outlined Civil Nuclear: Roadmap to 2050 as an opportunity to improve the United Kingdom’s energy independence from foreign sources as it looks to build a new power station and invest in advanced nuclear fuel production.
