Fuel

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.

The Nuclear Regulatory Commission has accepted an application from X-energy's fuel subsidiary, TRISO-X LLC, for a proposed TRISO-X Fuel Fabrication Facility (TF3) in Oak Ridge, Tenn., X-energy announced last week. A 30-month review schedule has been developed by the NRC that would be completed by June 2025, assuming TRISO-X provides sufficient responses to expected requests for additional information (RAIs) within 30 to 60 days of their issuance. On December 16, the NRC announced that it would seek public input on the scope of its environmental review and environmental impact statement for the application and published a notice in the Federal Register.

TerraPower, the advanced nuclear company backed by Bill Gates, announced last week that the start date for its Natrium reactor has been pushed back. As Russia is currently the only commercial source of the high-assay low- enriched uranium (HALEU) the plant requires, the company faces a lack of fuel availability. TerraPower originally planned to use Russian fuel to get its demonstration reactor up and running by 2028, but Russia’s invasion of Ukraine has dashed those plans.

Kairos Power has signed an agreement to produce TRISO fuel pebbles for the Hermes demonstration reactor at Los Alamos National Laboratory's Low Enriched Fuel Fabrication Facility (LEFFF) in New Mexico. Hermes is being deployed in Oak Ridge, Tennessee. The agreement was announced last week.

The Department of Energy’s Office of Nuclear Energy announced December 7 that its new HALEU Consortium is open for membership. And not just from U.S. enrichers, fuel fabricators, and others working in the front-end fuel cycle, but from “any U.S. entity, association, and government organization involved in the nuclear fuel cycle,” and—at the DOE’s discretion—“organizations whose facilities are in ally or partner nations.” The HALEU Consortium will essentially serve as an information clearinghouse to meet DOE-NE’s ongoing needs for firm supply and demand data as it supports the development of a commercial domestic high-assay low-enriched uranium (HALEU) infrastructure to fuel advanced reactors. The consortium is open for business almost one full year after the DOE first requested public input on its structure.

Centrus Energy confirmed on December 1 that its wholly owned subsidiary American Centrifuge Operating signed a contract with the Department of Energy, which was first announced on November 10, to complete and operate a demo-scale high-assay low-enriched uranium (HALEU) gaseous centrifuge cascade.

The Nuclear Regulatory Commission has conducted a special inspection at the University of Texas’s TRIGA Mark II nuclear research reactor in Austin to evaluate the use of improper fuel. The inspection was ordered following a notification from the University of Texas—Austin to the NRC that the research reactor had been operating for several months with two fuel elements that were not licensed for the reactor.

Consolidated Uranium plans to acquire Virginia Energy Resources, which owns Virginia Uranium and the Coles Hill Uranium Project, an undeveloped uranium deposit that sits under about 3,000 acres of land in south central Virginia. The state’s General Assembly has maintained a moratorium on uranium mining since 1982 that was upheld in the courts as recently as 2020, but Consolidated Uranium sees reason for “confidence that the moratorium on developing uranium projects in the state may ultimately be overcome,” and appears content to settle in for a wait.
