ABSTRACT:
The device includes a corium collector arranged below the vessel of the reactor, with circulation channels for cooling the collector and the corium. These channels are connected to a water feed and cooling-fluid removal circuit including a water storage tank, a tank for collecting fluid removed from the channels and a steam ejector which receives steam from the cooling fluid originating from the collection tank and sucks water from the storage tank and injects the water into the channels.
