Supply position
United States runs 63 operating units on PWR (square-lattice) fuel. 6 fabricators are documented for it. Westinghouse Electric Company is 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utilities do not publish fuel contracts.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.
