Advanced reactors and SMR programs consuming HALEU — TerraPower, X-energy, Kairos, Oklo and fleet demand
Centrus Energy and Radiant have finalized a multi-year HALEU supply contract for Radiant's Kaleidos microreactors, with deliveries starting before the end of the decade. The agreement includes crucial prepayments to support Centrus's domestic capacity expansion.
A massive $10 billion investment is planned for the Oak Ridge site to build a comprehensive advanced nuclear supply chain, including enrichment, fuel fabrication, and recycling.
Radiant is developing the 1-megawatt Kaleidos gas-cooled microreactor, designed for remote locations and defense applications. The reactor's unique design requires HALEU to achieve higher power density and a five-year operational core life without refueling.
Radiant Industries has signed a multi-year HALEU supply agreement with Centrus Energy to fuel its Kaleidos microreactors. The deal supports both commercial and national security applications ahead of 2030.
Urenco is building a dedicated HALEU facility in the UK targeting 10 metric tonnes annually, while X-energy secures additional DOE funding to deploy its Xe-100 reactors utilizing TRISO-X fuel.
Centrus Energy and Radiant have signed a multi-year HALEU supply contract to fuel Radiant's transportable Kaleidos microreactors, with deliveries expected by the end of the decade.
The U.S. Army's Janus microreactor program and TerraPower's Natrium reactor highlight the rapidly growing demand for HALEU, prompting significant investments in new production capacities across the U.S. and the UK.
The U.S. Army allocates up to $2.2 billion for the Janus microreactor program, selecting five companies and installations to achieve operational electricity by 2028.
Radiant has partnered with Centrus Energy to secure a domestic HALEU supply chain for its Kaleidos microreactors, featuring a five-year refueling cycle.
NANO Nuclear Energy and Enveniam have signed an MOU to collaborate on HALEU transportation, microreactor deployment, and domestic fuel supply. The partnership aims to commercialize advanced microreactors for energy-intensive applications.
Multiple advanced reactor developers, including Antares Nuclear, Valar Atomics, Oklo, and Deployable Energy, have achieved zero-power fuelled criticality. These milestones were supported by the DOE's Nuclear Energy Launch Pad initiative.
Driven by the explosive electricity demand from AI and data centers, companies like X-Energy and Oklo are developing advanced small modular reactors and fuel recycling services to meet commercial-scale energy needs.
