Notes
INL confirms consortium membership. Standard Nuclear (Oak Ridge, TN roots; CEO Kurt Terrani) is a TRISO/HALEU fuel company — now public (ticker STDN) after a $140M Series A (Jan 2026). Membership acknowledged only via an X quote-post of INL's award announcement (2026-07-22, x.com/standardnuclear/status/2080027280445747677); no press release or newsroom item details its Prometheus role. Fuel-supply activity: TRISO supply agreements with Radiant (2026-08-20) and 'Antares Nuclear' (2026-08-27) — possible overlap with consortium partner Antares Industries is unverified; Oklo strategic alliance (2026-06-16); DOE Surplus Plutonium Utilization Program advanced negotiations (2026-06-03). Implied TRISO-manufacturing data role is not publicly stated; role remains null and confidence remains low.
