US reactor vendors: GE still alive; Westinghouse and CE are now Toshiba assets; B&W now Areva

The former nuclear division of Westinghouse Electric, which had already absorbed Combustion Engineering, has been purchased by Toshiba. So, with Westinghouse, Toshiba gains two of the four companies that built the existing complex of American reactors. A third company, the commercial nuclear division of Babcock & Wilcox, is now in the hands of Areva, a French-German consortium. The fourth company is General Electric, which is trying to sell a newly designed reactor.
