Updated daily from the US reactor status feed. The NRC publishes a power
percentage only, with no reason for a reduction, so a unit at 0% may be refuelling, in a planned
outage or tripped. See outages.

Uranium dioxide pellets in zirconium-alloy cladding
Enrichment
3–5% U-235
Who makes this assembly
- Framatome BWR fuel assemblies
- Global Nuclear Fuel BWR fuel assemblies
- Westinghouse Electric Company BWR fuel assemblies
Supply position
United States runs 31 operating units on BWR fuel. 3 fabricators are documented for it. Global Nuclear Fuel and Westinghouse Electric Company are based in United States. 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utilities do not publish fuel contracts.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.
