Abstract:
A pressurized water reactor (PWR) includes a vertical cylindrical pressure vessel having a lower portion containing a nuclear reactor core and a vessel head defining an integral pressurizer. A reactor coolant pump (RCP) mounted on the vessel head includes an impeller inside the pressure vessel, a pump motor outside the pressure vessel, and a vertical drive shaft connecting the motor and impeller. The drive shaft does not pass through the integral pressurizer. The drive shaft passes through a vessel penetration of the pressure vessel that is at least large enough for the impeller to pass through.

Claim (Index 1):
A method comprising:\n installing a reactor coolant pump comprising a pump motor, a driveshaft, an impeller, and a mounting flange on a pressurized water reactor (PWR) comprising a pressure vessel and a nuclear reactor core disposed in the pressure vessel, the installing including:\n pre-assembling the pump motor, the driveshaft, the impeller, and the mounting flange outside of the pressure vessel to form a pump assembly as a unit disposed outside of the pressure vessel in which the pump motor is connected with the impeller by the driveshaft, \n inserting the impeller and the driveshaft of the pump assembly through an opening of the pressure vessel while the pump motor remains outside of the pressure vessel, and \n securing the flange of the pump assembly to an outside of the pressure vessel to mount the pump assembly on the pressure vessel, \n wherein the inserting and securing mounts the pump assembly on the pressure vessel with the drive shaft of the pump assembly oriented vertically.
