[en] Nuclear Power International (NPI), a joint subsidiary of Framatome and Siemens was established in April 1989 to coordinate the development and marketing of a common PWR technology for the world market. Both parent companies command well proven PWR technology and can rely on experience gained with over 100 000MWe of nuclear capacity in operation, under construction or on order. The technology from each is being offered through NPI until the joint PWR technology which is under development, becomes available. NPI's experience to date is reviewed. (author)
