Who makes this assembly
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Fabricator capability is recorded against reactor type and model line, not against named units — utilities do not publish fuel contracts.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.
