Beschreibung
Zusammenfassung:	An integral pressurized water reactor (PWR) includes a cylindrical pressure vessel, a cylindrical central riser disposed coaxially inside the cylindrical pressure vessel wherein a downcomer annulus is defined between the cylindrical central riser and the cylindrical pressure vessel, a nuclear core comprising a fissile material, and a steam generator disposed in the downcomer annulus. A reactor coolant pump (RCP) includes a jet pump disposed in the downcomer annulus above or below the steam generator, and a hydraulic pump configured to pump primary coolant into a nozzle of the jet pump. The hydraulic pump includes an electric motor mounted externally on the pressure vessel.
