ABSTRACT:
A pipe loop arrangement for the closed primary system of a nuclear reactor. The heated reactor coolant flows through a horizontally positioned hot leg pipe while the return flow cooled reactor coolant flows through a cold leg pipe concentrically mounted within the hot leg pipe. A bell-mounted suction port and the high pressure discharge port of the reactor coolant pump are located within an outlet chamber with the steam generator. A transition piece slip fitted to an opening within the reactor vessel outlet flange connects the cold leg pipe to the inlet to the nuclear core. A flow shroud surrounding the pump discharge connects the pump discharge to the cold leg pipe, forms a volute for the pump discharge and separates the outlet chamber from the inlet chamber of the steam generator.
