Reactor-agnostic TRISO fuel manufacturing at industrial scale

NuclearMaterialsEnergy
What they build

The product

Industrial-scale production of TRISO (TRistructural ISOtropic) fuel particles and advanced nuclear ceramics — the high-temperature, accident-tolerant fuel form required by most advanced reactor designs (X-energy Xe-100, Kairos KP-FHR, USNC, microreactors). Operates a campus at 200 Europia Ave, Oak Ridge, TN, and was the first company conditionally chosen for a DOE-authorized fuel fabrication facility under the Advanced Nuclear Fuel Line Pilot.

Why it matters

The thesis

TRISO supply is the binding constraint for most US advanced reactor deployments. Standard Nuclear is an Andreessen-Horowitz / Decisive Point-backed bet on becoming the reactor-agnostic merchant TRISO supplier — the 'TSMC of advanced nuclear fuel.' Their $42M seed (Jun 2025) plus $140M Series A (Dec 2025) and partnership with SHINE on fuel recycling make them a critical chokepoint to watch.
