FactoryRegistry lists 457 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced nuclear reactor steam supply systems, heat exchangers and condensers, pressurizers, components, and auxiliary equipment, in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
