Zusammenfassung:	PROBLEM TO BE SOLVED: To contrive the rationalization of the power source system of a nuclear reactor pressure vessel incorporated recirculation pump, and the cost reduction of a nuclear plant construction. SOLUTION: A first recirculation pump 4 having a function utilizing only motor torque recirculating the coolant 3 of the reactor core 2 of a nuclear reactor pressure vessel 1 as a drive source, a second recirculation pump 5 having a function utilizing the motor torque and steam turbine torque as a drive source, a pump power source device for supplying electricity to the first and second recirculation pumps 4, 5, a first cooling system for cooling the pump power source device, and a second cooling system for operating and cooling the motor part of the second recirculation pump and a driving steam turbine, are provided.
