Nuclear reactor with a reactor core enclosed in a waterfilled core vessel, the core vessel being connected to an inlet and an outlet for cooling water, comprising at least one hydraulic connection between the outlet and at least one heat exchanger, at least one hydraulic connection between the inlet and said heat exchanger, a re-circulation pump (17) for transporting cooling water through said reactor core, and lower and upper density locks (5,6) for said core vessel, said core vessel and said reactor core being enclosed in a containment space 10,11 which is filled and pressurzied with a neutron absorbing aqueous solution. To be able to design a smaller unit of nuclear power plant, according to the invention, the containment vessel 10,11 of pre-stressed concrete has been made in the form of a bottle. In this way, a "conventional" pump with a shaft packing and a dry motor can be used by locating the motor, for driving the pump for circulation of the process water, in a sealed, detachably connected steel dome 16. When being removed, the steel dome 16 provides access to the riser 1 for refuelling. |
