摘要： The present invention includes a casing 11 and a rotary mechanism provided with an impeller 12 and an output shaft 13a that come into contact with primary cooling helium containing radioactive nuclides passing through the casing 11. The impeller 12 and the output shaft 13a of the rotary mechanism are composed of an Ni-base alloy doped with an element having a lower lattice diffusion coefficient than Ni. This can prevent radioactive nuclides from deeply diffusing into a material constituting a rotor or a rotor shaft that come into contact with coolant containing radioactive nuclides, thereby reducing the cost of maintenance.

摘要： 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 internal 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 internal pressurizer. A central riser may be disposed concentrically inside the pressure vessel, and the RCP impels primary coolant downward into a downcomer annulus between the central riser and the pressure vessel. A steam generator may be disposed in the downcomer annulus and spaced apart from with the impeller by an outlet plenum. A manway may access the outlet plenum so tube plugging can be performed on the steam generator via access through the manway without removing the RCP.

摘要： The invention relates to a pump that includes: a chamber (4) for heat-transport fluid flow; a pump wheel (10) which is placed entirely in the flow chamber (4) and which comprises a hub (40); a shaft (14) for rotating the pump wheel (10), having an axial end section (12) rigidly connected to the pump wheel (10) and fitted in the hub (40) of the pump wheel (10); a motor for rotating the shaft (14) about the axis thereof; and means for causing a coolant for cooling the drive shaft (14) to flow, at a temperature lower than that of the heat-transport fluid, along the drive shaft (14). Said pump also includes a shield (120) for protecting the pump wheel (10) against a coolant leak along an outer peripheral surface (48) of the hub (40) of said pump wheel (10), said protective shield (120) being attached to the pump wheel (10).

摘要： The present invention relates to an internal pump.
A water pass hole (33) through which inner and outer peripheries of a stretch tube (24) are communicated with each other, is formed in a portion of the stretch tube corresponding to a joint between and end face of a nozzle section (14a) of a motor case (14) and an end face of a diffuser (13), so that high temperature reactor water in a pressure vessel (1) entering through the joint between the end face of the nozzle section (14a) of the motor case and the end face of the diffuser (13) is made to merge into purge water so as to be returned into the pressure vessel (1) again.
