A method and arrangement for containing the core melt flowing from a nuclear reactor into a core catcher below the core wherein the core melt is permitted to gradually penetrate layers of a core catcher materials of inorganic reactor soluble oxides or salts disposed in the core catcher which core catcher materials are dissolved by the oxidic part of the core melt, and the molten solution, after solidification and after being cooled down to a temperature at which hydrogen generating reactions do not take place, is leached with water and rinsed out of the core catcher without the need for humans to be present in the reactor containment and to be exposed to radiation.
A core catcher arranged in a reactor containment below a nuclear reactor for containing the core melt flowing from the core of the nuclear reactor during a reactor core melt-down accident, said core catcher comprising:
