Enrichment
3–5% U-235
Who makes this assembly
- TVEL Fuel Company VVER fuel assemblies
- Westinghouse Electric Company VVER-compatible fuel assemblies
Supply position
Finland runs 2 operating units on VVER (hexagonal) fuel. 2 fabricators are documented for it. No documented fabricator is based in Finland. Country exposure
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.
Fabricator capability is recorded against reactor type and model line, not against named units,
utilities do not publish fuel contracts. See the fuel chain.
