A brief visit to the
Westinghouse Nuclear web site may help you avoid speculation. Westinghouse employs several hundred engineers in Windsor Connecticut and hundreds more in Monroeville Pennsylvania. Westinghouse has spent a fortune in research and development. The plant owners do not pay a 'royalty' to Westinghouse, GE, B&W or CE. The utilities purchase fuel contracts from the reactor vendors who have design information on all of the plants they built giving reactor vendors a competitive advantage in those situations. It is rare, but not unheard of, for a utility to sign fuel contracts with one of the reactor vendors different from the one that supplied the NSSS.
