ABSTRACT:
A passive "core catcher" is provided for preventing the escape of radiation in the unlikely event of a major failure of a nuclear reactor by melt-down of the core. The "core-catcher" structure includes a narrow vertically downwardly extending isolation tube, and aligned narrow heat-exchange structure forming a chilled wall crucible in which the molten uranium oxide forms a container for itself including a "frozen" or solid layer of uranium oxide adjacent the heat exchanger wall. A passive cooling system may include a water tower adjacent the above-ground reactor structure, which dissipates heat from the core-catcher heat exchanger, and from within the above-ground reactor structure by a second local heat exchanger.
