Change record

What changed

  • Centrus and Antares announced a definitive multi-year HALEU supply contract on September 17, including Antares prepayments intended to support expanded U.S. enrichment capacity.
  • Urenco said on September 15 that its Capenhurst advanced-fuels plan targets commercial-scale HALEU production by 2031.
  • The announcements are demand and capacity-build evidence; they do not establish current commercial HALEU abundance.

Public interpretation

Why it matters

Contracted demand is becoming more concrete while major incremental enrichment capacity remains a multi-year build, reinforcing the need to track qualification, funding and delivery milestones separately.
