Sep 09, 2026, 06:49 ET Agreement adds another domestic, U.S.-origin source of HALEU to support commercial and national security deployments of Radiant's Kaleidos microreactors Adds another HALEU customer to Centrus' backlog and includes prepayments to Centrus that advance its build-out of domestic enrichment capacity BETHESDA, Md., Sept. 9, 2026 /PRNewswire/ - Centrus Energy Corp. [NYSE: LEU] ("Centrus"), a trusted supplier of nuclear fuel and services, and Radiant, a leading developer of transportable plug-in ready nuclear microreactors, today announced a definitive multi-year contract to supply high-assay, low-enriched uranium (HALEU) fuel needed to deploy multiple Kaleidos microreactors. Under the agreement, Centrus will begin delivering HALEU before the end of the decade, adding another domestic source of fuel to support commercial scale-up of Radiant's Kaleidos fleet. The contract further strengthens Centrus' position as a leading fuel supplier for next generation nuclear technologies while expanding its role in the emerging microreactor market. The agreement includes Radiant prepayments to Centrus to support its domestic commercial enrichment capacity program. For Radiant, the contract adds another domestic source of HALEU as the company moves from its first Kaleidos test toward commercial and national security deployments, reinforcing the fuel supply it continues to build in parallel with the reactor itself. "The contract with Radiant marks another important step in building the domestic fuel supply chain needed to support the next generation of nuclear energy," said Amir Vexler, President and Chief Executive Officer of Centrus. "By expanding our work to include innovative microreactor developers like Radiant, we are strengthening the U.S.-based fuel supply network. This will help ensure that emerging nuclear technologies have access to the reliable fuel they need to reach commercialization and meet growing demand for clean, secure, and dependable energy." "You can't deploy nuclear reactors without fuel, so we have approached our fuel supply the same way we have approached the reactor: build it in parallel, and don't depend on any single path," said Dr. Rita Baranwal, Chief Nuclear Officer of Radiant. "This agreement gives Kaleidos a continued source of HALEU for commercial and national security applications and removes one of the biggest constraints facing advanced nuclear deployment. We're securing the fuel supply chain alongside the reactor so that when Kaleidos is ready to deploy at scale, the infrastructure behind it is ready too." Because Centrus' technology is U.S.-origin and relies upon a U.S. manufacturing supply chain, the enrichment that Centrus provides to Radiant will be "unobligated" - meaning that it can be used for national security applications. Centrus' AC100 centrifuge design is the only deployment-ready U.S.-origin technology available for unobligated enrichment today. Radiant is developing transportable microreactors designed to provide reliable power for remote locations, data centers, defense applications, and/or other commercial and industrial uses, representing a broad potential market for Centrus' domestic HALEU supply. About Centrus Centrus Energy is a trusted American supplier of nuclear fuel and services for the nuclear power industry, helping meet the growing need for clean, affordable, carbon-free energy. Since 1998, the Company has provided its utility customers with more than 1,850 reactor years of fuel, which is equivalent to more than 7 billion tons of coal.

The Army just put A price on five nuclear microreactors for U.S. Bases. The Army just put a price on its plan to install nuclear microreactors at five military bases across the eastern U.S. - $2.2 billion. The payout flows to five nuclear energy players, including BWX Technologies and Westinghouse Government. Microreactors can be a thousand times smaller than conventional reactors, with correspondingly small footprints that lend themselves to factory assembly, delivery by truck or air, and flexible deployment. They're part of the Trump administration's push to quench surging electricity demand, much of it AI-driven, with nuclear power. How This Uranium Enrichment Technology Aims To Solve The Nuclear Fuel Bottleneck For Big Tech AI data centers require 24/7 power, a demand only nuclear energy can meet. But the industry faces a major hurdle: fuel supply. LIS Technologies CEO Jay Yu breaks down the shift toward domestic uranium enrichment and the roadmap to securing America's energy future. How This Uranium Enrichment Technology Aims To Solve The Nuclear Fuel Bottleneck For Big Tech See All Videos Microreactors are a category of especially petite small modular reactors (SMRs), defined by the Energy Information Administration as ranging from 1 to 20 megawatts of output. The low end of that range is enough to power hundreds of homes at peak demand. None of these development-stage reactors is yet ready for commercial use or military deployment. BWX, Westinghouse land contracts. BWX Technologies (BWXT) is the sole publicly traded vendor selected by the Army. It's set to design and deploy a microreactor for Kentucky's Fort Campbell. Westinghouse Government - a unit of Westinghouse Electric, a joint venture owned by Brookfield Renewable Partners (BEP) and Cameco Corp. (CCJ) - is slated to do the same for New York's Fort Drum. BWX traded close to 1% lower Monday afternoon. Shares are down 12% year to date, after rallying 54% in 2025. Cameco stock shed more than 2%, narrowing its 2026 gain to just under 7%. It rocketed 78% in 2025. Private firms Radiant Industries, General Atomics Electromagnetic Systems and Antares Nuclear will develop units in Georgia, Texas and North Carolina. Each vendor is contracted to design, own, deploy and operate their respective microreactors. They're also responsible for handling nuclear waste disposal within two years, the New York Times reports.

None operate commercially in the U.S. to date. There are dozens of SMRs in various stages of development and deployment across the U.S. "With the private sector funding expected along with these government dollars, the Army expects more than 20 total nuclear microreactors will be built and operated across Department of War installations," the military said in a statement. Microreactors: opportunities and challenges. Microreactors rely on nuclear fission to generate heat and turn turbines with steam. Their primary perk is modularity, which means developers can build and ship them, while buyers could stack modules as needed to meet rising energy demand. The extra small reactors are "(price-competitive) with technologies with similar scale and application," according to a 2021 review published in the journal Progress in Nuclear Energy. But microreactors still yield radioactive waste and face strict regulatory hurdles. Specifically, the availability of the specialized HALEU fuel remains a critical bottleneck for the technology. The Army expects to secure enough high-assay low-enriched uranium (HALEU) for about 20 microreactors, a spokesperson told the New York Times. Beyond that, the Energy Department is attempting to kick-start a domestic supply chain for the fuel through purchase agreements. Follow Harriet Weber on LinkedIn and Bluesky.

Radiant wins $750M contract from US Army to deliver energy independence to US military bases. Janus program advances national security and resilient energy to support defense installations August 26, 2026 EL SEGUNDO, Calif. - August 26, 2026 - Radiant, the company building the world's only plug-in ready, transportable commercial nuclear microreactors, today announced that the U.S. Army, in partnership with the Defense Innovation Unit (DIU), has executed a binding agreement totaling up to $750 million dollars to develop and deploy 15 Kaleidos nuclear microreactors through the Army's Janus Program. Radiant's award is one of the largest contracts ever issued by DIU across their portfolio, and the largest award within the Janus Program. "The U.S. Army is a savvy customer. They have the world's top nuclear experts and know what to look for in a partner," said Tori Shivanandan, President and Chief Operating Officer of Radiant. "The numbers tell the story. This award shows confidence in Radiant's product and ability to manufacture, deploy, and safely operate nuclear microreactors for the American military. We thank Dr. Waksman and Director Owen West for their leadership. This program will build a stronger and more resilient America while accelerating our operational excellence." The contract accelerates Radiant's customer deployment of nuclear microreactors at scale. Radiant will manufacture a fleet of factory-built, fully transportable reactors capable of delivering reliable, independent power for military installations and other critical national security missions. "The Army was very thoughtful in designing the Janus Program to capitalize on the complementary strengths of the government and private sector. They got it exactly right,"" said Mike Starrett, Chief Commercial Officer at Radiant. "Through Janus, Radiant will deploy 15 reactors by 2030, identical in design to the units serving our commercial customers. Operating on military installations first gives us the reliability track record to unlock commercial deployments, and the resulting, much larger commercial volume drives down costs, letting the Government buy at scale for less. It's a powerful accelerant for Radiant, made possible only through Janus." The Army launched the Janus Program to strengthen the energy resilience of military installations and mission-critical infrastructure. Radiant was chosen after extensive evaluation of reactor design, technical maturity, manufacturing readiness, deployment strategy, and commercial viability. Radiant's 15 microreactors will enable the Army to deploy nuclear power across multiple locations. In tandem, the operational data acquired through the Program will accelerate commercial deployments across a global footprint of commercial customers. "The Janus Program is about transitioning from designs and experiments to reliable commercial hardware which secures our energy independence," said Dr. Jeff Waksman, Principal Deputy Assistant Secretary of the Army for Installations, Energy and Environment. "The Janus Program vendors were selected through a deeply rigorous evaluation on technical, financial, and organizational capabilities conducted by an all-star panel of dozens of experts from across the nation. We look forward to working alongside each team as they proceed toward successfully completing the rigorous technical milestones we've agreed upon." Kaleidos is a 1-megawatt nuclear microreactor, transportable by land, sea, or air and deployed directly at customer sites. Plug-in ready, each reactor provides up to five years of power before refueling and is engineered with a 20-year operating life cycle. Unlike permanently installed nuclear facilities that require long lead times and site-specific construction, Kaleidos provides energy in a box. It requires no cooling water, and it is not a "hole-in-the-ground" reactor. The reactor arrives as a sealed, fueled unit that can be plugged in immediately. Additional units can be added or relocated as energy requirements evolve. Radiant manages fueling, refueling, and spent-fuel storage at its own facilities, allowing customer sites to return to greenfield condition, within two years or less after a unit is removed. Customer sites never have onsite spent fuel storage. Radiant's Kaleidos reactor is undergoing the country's most rigorous test campaign at the Idaho National Laboratory DOME facility, which was updated for small modular reactor testing in 2026. Following a competitive selection process, the Department of Energy awarded Radiant exclusive access to the facility for a full year. Kaleidos is undergoing the industry's only full-scale, full-power, extended duration reactor test- using the same reactor design and custom spec'd fresh fuel that will be used for customers deployments. Beyond reactor development, Radiant is standing up the entire vertically integrated industrial capability required to manufacture, fuel, deploy, and service its products. Radiant is already under construction on its 300,000-square-foot R-50 manufacturing, fueling and storage campus in Oak Ridge, Tennessee. The company will fuel its own reactors and control every step of production through end-to-end ownership of the supply chain. The Janus award builds on Radiant's previous selection by the Department of the Air Force and DIU to develop and operate Kaleidos microreactors at Buckley Space Force Base in Colorado. These government deployments will further validate Kaleidos in real-world operating environments, advancing the product and demonstrating its readiness for commercial deployment. Radiant has already signed an agreement with Equinix for 20 Kaleidos units and continues to advance commercial opportunities across data centers, advanced manufacturing, critical infrastructure and other commercial applications. Radiant is decentralizing the grid, 1-megawatt at a time, and converting the grid to backup power to save money for its customers. About Radiant Radiant is a leading developer of advanced nuclear technologies focused on delivering reliable, resilient, and scalable energy solutions that are transportable by land, sea and air. Radiant is committed to enabling a new generation of nuclear applications for commercial, industrial, and defense customers. Media Contact Agnes Gomes-Koizumi

U.S. Army awards $2.2 billion to build nuclear microreactors. Aug 27, 2026 Modified date: Aug 27, 2026 Key Points * The U.S. Army selected five companies, including Westinghouse and Radiant, to build nuclear microreactors at five bases under its $2.2 billion Janus Program. * Radiant's $750 million award, the largest of the five, covers 15 microreactors beginning with a three-unit installation at Fort Benning. The U.S. Army has selected five companies to build and operate nuclear microreactors at military installations across the country, awarding up to $2.2 billion in combined funding under its Janus Program, the Army announced. Westinghouse Government Services will supply its eVinci microreactor to Fort Drum, New York. Antares Nuclear will build at Fort Bragg, North Carolina. BWXT Advanced Technologies is set for Fort Campbell, Kentucky. General Atomics Electromagnetic Systems will deliver to Fort Hood, Texas. Radiant Industries will build at Fort Benning, Georgia. The Janus Program is run in partnership with the Department of War Innovation Unit and is intended to move advanced microreactor technology beyond test programs and into sustained operation at defense installations, according to the Army. - ADVERTISEMENT - CONTINUE READING BELOW - Discover more Access Premium News U.S. Air Force Join Air Force "Reliable energy is fundamental to mission assurance, operational readiness and national security," said Rich Rademacher, President of Westinghouse Government Services. "The selection of the eVinci microreactor for the Janus Project highlights the important role advanced nuclear technology can play in providing resilient, long-duration power to the warfighter." "The Janus Program is about transitioning from designs and experiments to reliable commercial hardware which secures our energy independence," said Dr. Jeff Waksman, Principal Deputy Assistant Secretary of the Army for Installations, Energy and Environment. "The Janus Program vendors were selected through a deeply rigorous evaluation on technical, financial, and organizational capabilities conducted by an All-Star panel of dozens of experts from across the nation." The eVinci is a heat-pipe reactor Westinghouse says is designed to provide continuous electricity for eight years without refueling. The planned microreactors across the five installations will generate under 20 megawatts of electricity each and occupy less than five acres of land, according to the Army. Radiant disclosed the largest agreement among the five vendors: up to $750 million to deploy 15 factory-built, 1-megawatt Kaleidos microreactors by 2030, beginning with a three-unit installation at Fort Benning. Radiant's Kaleidos reactor is transportable by land, sea or air and is designed to be deployed directly at customer sites, according to the company. "The Army's $750 million award shows confidence in Radiant's product and ability to manufacture, deploy and safely operate nuclear microreactors for the American military," said Tori Shivanandan, president and chief operating officer of Radiant. None of the planned reactors will use highly enriched, weapons-grade uranium, according to Waksman. The Janus Program follows the Pentagon's 2022 Project Pele initiative, which developed a portable 40-ton reactor capable of generating 1 to 5 megawatts of power. Army officials said the current program is funded for five years, with a target of having at least one microreactor producing usable electricity at an installation by September 30, 2028. The five sites selected represent the first tranche of installations under Janus, with Army officials anticipating that additional private investment from the companies could bring the total number of microreactors across all installations to more than 20. The push into military nuclear power comes as private companies increasingly move into a fuel-cycle sector long dominated by government programs. Christo Liebenberg, co-founder of uranium enrichment company LIS Technologies, told The Defence Blog in March that domestic enrichment capacity sits at the center of both civilian and defense nuclear infrastructure, and that private firms can move faster than institutional programs in developing fuel supply for smaller reactors built for remote or secure military installations.
