Overview
Standard Nuclear produces high-assay low-enriched uranium (HALEU) fuel for advanced reactors and small modular reactors (SMRs). Domestic HALEU supply is a bottleneck for next-gen nuclear deployment; Standard Nuclear builds enrichment and fuel fabrication capacity in the US. The company raised $42M seed in June 2025 led by Decisive Point with a16z participation, then $140M Series A in January 2026.
Why Standard Nuclear is interesting
American Dynamism nuclear fuels bet — seed to $140M Series A in six months scaling domestic HALEU output for SMRs.

Standard Nuclear develops HALEU production facilities and fuel fabrication for advanced reactor designs requiring higher enrichment than traditional LWR fuel.
- Fuel supply for SMR and microreactor developers
- Domestic HALEU enrichment capacity
- Advanced reactor demonstration programs
- Energy security and nuclear fuel independence
