Solid drainage material for the emergency collection pit.
The ceramic foam removes the water and steam and melts in connection with expanded silicic acid when it comes into contact with liquid metal on the surface in order to prevent the metal penetrating it. The ceramic foam separates water from liquid metal and therefore rules out the danger of a physical explosion. The animation shows a real water test in the cell of an emergency collection pit with ceramic foam.
