Actinide is first startup to produce high-assay low-enriched uranium (HALEU)

Startup Actinide has become the first company to produce high-assay low-enriched uranium (HALEU) using proprietary calutron technology. This development offers a potential domestic alternative to traditional centrifuge enrichment for advanced nuclear reactors.
Why it matters
HALEU is a critical fuel for next-generation nuclear reactors, and domestic production is currently a significant bottleneck for the energy industry.
