Dallas, TX, August 26 — Actinide , an advanced materials company that designs, builds, and operates its own isotope separation machines, has become the first startup in history to produce high-assay low-enriched uranium (HALEU). The enrichment was performed on the company's first-generation calutron, which, weeks earlier, was producing Actinide’s flagship commercial product: enriched ytterbium-176, delivered to Oklo Isotopes. There is no end-to-end domestic supply chain for HALEU-based fuel: the Department of Energy says that most advanced reactor designs require HALEU, yet there is currently zero available from domestic suppliers . While conventional centrifuge enrichment is able to produce enriched uranium hexafluoride gas, this still must be converted into solid form before fuel fabrication - a process for which the United States has zero commercial capacity .…
