Abstract
To be able to design a smaller unit of a nuclear power plant, the containment 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 detachably connected steel dome (16) provides access to the riser (1) for refuelling.
