HALEU

Over nearly five decades, nuclear waste has been treated as an intractable problem, locked in dry casks, relegated to repositories that are slow to materialize, and generally viewed as a costly liability

The U.S. Department of Energy (DOE) has unveiled three more companies to which it will allocate high-assay low-enriched uranium (HALEU) under conditional commitments in a bid to support advanced reactor development and domestic fuel production. The Aug. 26 announcement marks the second round of allocations under DOE’s HALEU Availability Program but it links to two […]

Advanced nuclear firm Aalo Atomics has secured new capital and regulatory backing to complete construction of its 10-MWe Aalo-X reactor at Idaho National Laboratory (INL). The project, recently selected under the Department of Energy’s (DOE’s) new Nuclear Reactor Pilot Program, will demonstrate cold criticality by July 2026 in an unusually aggressive federal milestone for advanced […]

Nuclear power has emerged as a linchpin for U.S. goals for energy and national security. The nuclear sector has a long history of bipartisan support in the federal government.

Centrus Energy has produced and delivered 900 kilograms (kg) of High-Assay, Low-Enriched Uranium (HALEU) to the U.S. Department of Energy (DOE), completing Phase II of its pioneering enrichment contract with the agency. The shipment marks the first significant domestic production of HALEU—a specialized fuel required for many advanced reactors now under development—and stands as a […]

The U.S. Department of Energy (DOE) is inviting private-sector nuclear developers to submit proposals for experiments and demonstrations using its Microreactor Application Research Validation and Evaluation (MARVEL) project. The first-of-its-kind operational test bed for advanced microreactor technologies is now 90% through its final design phase, with key components already under fabrication. Idaho National Laboratory (INL), […]

Advanced nuclear developer Oklo announced it has successfully completed borehole drilling for site characterization work at its Idaho National Laboratory (INL) site, marking a pivotal milestone as the company progresses toward constructing its first commercial Aurora Powerhouse—a liquid sodium–cooled fast reactor designed for scalable deployment. The standard nuclear project development step, involved “drilling of several […]

A company working to mass produce portable nuclear microreactors said its has accepted its selection by the U.S. Dept. of Energy (DOE) to receive high-assay low-enriched uranium (HALEU) fuel for the first test of Kaleidos, the group’s reactor design.

In a critical step aimed at bolstering advanced reactor development and their domestic nuclear fuel readiness, the U.S. Department of Energy (DOE) has issued its first round of allocations for high-assay low-enriched uranium (HALEU) under its HALEU Availability Program to five American nuclear developers. On April 9, the DOE said it made conditional commitments to […]

Advanced reactor developer X-energy and global materials science company Dow have submitted a construction permit application (CPA) to the U.S. Nuclear Regulatory Commission (NRC) for a first-of-its-kind small modular reactor (SMR) project at Dow’s Union Carbide Corp. (UCC) Seadrift Operations in Calhoun County, Texas. The filing marks a major step forward for the much-watched commercial-scale […]
