Abstract
An improved pressurized water-cooled reactor system which includes a reactor core pressure vessel; coolant lines coupled to the pressure vessel; vertically arranged steam generators having the housings thereof coupled to the coolant lines; and coolant pumps associated with the steam generators and coupled to the coolant lines. Each of the pumps has a vertically arranged impeller portion driven by an electric motor for circulating coolant between the pressure vessel and tube sheet type heat exchangers in the steam generators, at least the impeller portion of each pump being disposed within a chamber associated with each steam generator which is communicative with the coolant lines. The vessel, the coolant lines and the steam generators including the impeller chamber are each individually encapsulated by rupture-proof safety housings (encasements) forming a protection system for the primary loop components.
