Fuel chain for this unit
Fuel form
TRISO-coated particle fuel in pebbles or compacts
Enrichment
8–20% U-235, frequently HALEU HALEU dependency
Who makes this assembly
- BWX Technologies TRISO particle fuel
- X-energy TRISO particle fuel, HALEU enrichment
Upstream
Enriched fuel means this unit sits downstream of five conversion plants and four enrichment operators holding 88% of world capacity between the top three.
This design needs HALEU, enrichment above 5%. Western production is currently measured in hundreds of kilograms a year.
Fabricator capability is recorded against reactor type and model line, not against named units,
utilities do not publish fuel contracts. See the fuel chain.
