The European Union has selected a Westinghouse-led consortium to develop and deliver “a secure, fully European nuclear fuel supply” for Russian-designed VVER reactors in the EU and Ukraine, the U.S.-based firm announced last week.

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.

Westinghouse Electric Company has signed a contract extension with EDF Energy to supply fuel for the United Kingdom’s advanced gas-cooled reactor (AGR) fleet, the American firm announced yesterday.

Ultra Safe Nuclear (USNC) announced on June 21 that it has selected the city of Gadsden, Ala., to host a $232 million MMR assembly plant. Modules for the company’s high-temperature, gas-cooled and TRISO-fueled microreactor, dubbed the Micro-Modular Reactor (MMR), would be manufactured, assembled, and tested at the “highly automated facility” once it is in operation.

Centrus Energy announced yesterday that it has received Nuclear Regulatory Commission approval to introduce uranium hexafluoride into its 16-machine centrifuge cascade in Piketon, Ohio, following operational readiness reviews by the NRC. Centrus says it “remains on track to begin production of high-assay low-enriched uranium (HALEU) by the end of 2023.” The announcement follows a series of inspections at the American Centrifuge site in April 2023.

The Department of Energy released two draft requests for proposals to acquire high-assay low-enriched uranium (HALEU)—one covering enrichment services that could include the production of between 5 and 145 metric tons of HALEU during a 10-year performance period, and another for deconverting that HALEU from uranium hexafluoride (UF₆) gas to metal or oxide forms in preparation for fuel fabrication. The DOE also issued a notice of intent to fulfill its National Environmental Policy Act (NEPA) obligations for the HALEU Availability Program by launching the scoping process for an environmental impact statement; that notice was published in the Federal Register on June 5.

McMorris Rodgers

The House Energy and Commerce Committee has advanced a bill to the chamber’s floor that, with certain exceptions, would ban the import of low-enriched uranium from Russia into the United States. Introduced in February by the E&C Committee’s chair, Cathy McMorris Rodgers (R., Wash.), the Prohibiting Russian Uranium Imports Act (H.R. 1042) was approved in a (slightly) bipartisan 29–21 vote on May 24.

The legislation would start banning Russian uranium 90 days after its enactment but would also allow the Department of Energy to issue waivers should the DOE determine (1) that there is no alternate source of low-enriched uranium available to keep a U.S. nuclear reactor in operation or (2) that importing Russian uranium is in the national interest.

Framatome is prepared to manufacture a novel molybdenum-uranium (U-Mo) fuel to extend the life and safe operation of the Forschungsreaktor München II (FRM II) research reactor in Germany. A new fuel supply—one that uses uranium enriched to less than 20 percent U-235—means the FRM II can continue to supply neutrons to industry and the scientific community. The fuel is “Europe’s low-enriched fuel with the highest density ever realized for research reactor operations,” according to Framatome’s April 27 announcement.

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.)

A civil nuclear fuel security agreement between the five nuclear leaders of the G7—announced on April 16 on the sidelines of the G7 Ministers’ Meeting on Climate, Energy and Environment in Sapporo, Japan—establishes cooperation between Canada, France, Japan, the United Kingdom, and the United States to flatten Russia’s influence in the global nuclear fuel supply chain.

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).

Canadian firms Cameco and Bruce Power have announced a 10-year extension of their long-term exclusive nuclear fuel supply arrangements, securing power generation from the eight-unit 6,507-MWe Bruce nuclear plant through 2040.

The Department of Energy reported on March 30 that the Savannah River Site’s H Canyon facility recently initiated actions to recycle a small amount of used high-enriched uranium (HEU). SRS is a 310-square-mile DOE site in South Carolina.

The HEU, which is currently stored at the site’s H Area, will be downblended in a few years into high-assay low-enriched uranium (HALEU), which will help to provide fuel for advanced nuclear reactors in the United States.

The DOE has a brief video available with graphic information about HALEU.

Westinghouse has signed an agreement with ČEZ, owner and operator of the Czech Republic’s nuclear power plants, to supply VVER-440 fuel assemblies to the Dukovany facility, the American firm announced March 29. Fuel deliveries will commence in 2024, replacing Russia’s TVEL fuel, with an anticipated term of seven years. One of the Czech Republic’s two nuclear power plants, Dukovany houses four Russian-supplied VVER-440/V213 reactors.

Westinghouse Electric Company announced on March 14 that the Nuclear Regulatory Commission has approved the use of the company’s Advanced Doped Pellet Technology (ADOPT) fuel pellets in U.S. pressurized water reactors. That approval brings the company closer to loading lead test assemblies containing ADOPT accident tolerant fuel pellets in Unit 2 of Southern Nuclear’s Vogtle plant.

Manchin

Barrasso

A bipartisan group in the Senate is making another attempt to ban Russian uranium with the introduction of S. 763, the Reduce Russian Uranium Imports Act, after similar legislation introduced in the previous Congress just under one year ago by Sen. John Barrasso (R., Wyo.) failed to advance.

Debuting March 9, the new bill is sponsored by Barrasso and Sens. Joe Manchin (D., W.Va.), Jim Risch (R., Idaho), Martin Heinrich (D., N.M.), Cynthia Lummis (R., Wyo.), Chris Coons (D., Del.), and Roger Marshall (R., Kan.). Specifically, S. 763 calls for prohibiting “the importation into the United States of unirradiated low-enriched uranium that is produced in the Russian Federation or by a Russian entity.”

Lightbridge Corporation, which is continuing to work closely with national laboratories on the manufacture and testing of its metallic fuel rod designs for light water reactors, just announced the results of an investigation on the casting process for molten uranium and zirconium with Pacific Northwest National Laboratory under the Department of Energy’s Gateway for Accelerated Innovation in Nuclear (GAIN) program.

Centrus Energy announced February 9 that it has finished assembling a cascade of uranium enrichment centrifuges and most of the associated support systems ahead of its contracted demonstration of high-assay low-enriched uranium (HALEU) production by the end of 2023. When the 16-machine cascade begins operating inside the Piketon, Ohio, American Centrifuge Plant, which has room for 11,520 machines, it will be the first new U.S.-technology based enrichment plant to begin production in 70 years.

The Nuclear Regulatory Commission recently presented its proposed 30-month licensing review timeline of TRISO-X’s planned fuel fabrication facility at the project’s first-ever public meeting in Oak Ridge, Tenn.

TRISO-X, a subsidiary of X-energy, has requested a 40-year license to possess and use special nuclear material to manufacture advanced fuel. The facility would be the first-ever commercial-scale fuel fabrication plant focused on using high-assay low-enriched uranium (HALEU).

Westinghouse Electric and Framatome have signed agreements with Kozloduy NPP—the eponymous operator of Bulgaria’s only nuclear power facility—to fabricate and deliver fuel for the site’s two operating reactors. Westinghouse will provide the fuel for Unit 5 under a 10-year contract inked on December 22, while Framatome will supply Unit 6 under a December 30 preliminary deal. First deliveries of fuel from Westinghouse and Framatome are expected in 2024 and 2025, respectively.

The two agreements, according to the Bulgarian News Agency, “are part of an effort to diversify energy supplies to Bulgaria and do away with the country’s dependence on Russian energy resources.” In November, the Bulgarian National Assembly approved 156–47 a resolution tasking the country’s Council of Ministers with licensing non-Russian nuclear fuel for Kozloduy.
