Fuel form
not established for this unit's type
Enrichment
not established HALEU dependency
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utilities do not publish fuel contracts.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.
