This patent describes a nuclear reactor coolant pump for pumping reactor coolant fluid in a reactor coolant system. It comprises a casing defining an inlet nozzle for receiving a reactor coolant fluid, a converging spout outlet nozzle for discharging the reactor coolant fluid, and a passage interconnecting the inlet nozzle and the outlet nozzle through which the reactor coolant fluid can flow from the inlet nozzle to the outlet nozzle; a rotor extending axially through the casing and having an end disposed adjacent the passage defined by the casing; and an impeller mounted to the end of the rotor and disposed in communication with the passage, the impeller being rotatable with the rotor about an axis, the impeller being axially offset from the outlet nozzle for drawing fluid into the casing through the inlet nozzle and discharging fluid from the casing tangentially through the converging spout outlet nozzle after flow through the passage; the converging spout outlet nozzle being composed of first and second wall portions defined above and below an imaginary plane extending generally parallel to the rotation axis of the impeller, the first wall portion extending substantially tangentially to the casing and having a substantially semi-cylindrical shape, the second wall portion having a combined substantially semi-elliptical and semi-conical shape.
