Process to transport carbon from a zone to another one, by means of a carrier fluid acting inside a closed system, particularly for the reprocessing of nuclear fuel elements having a graphite

Image Number 2 for United States Patent #3984519.

A method is disclosed for eliminating carbon from nuclear fuel elements in the reprocessing thereof in a closed system wherein such carbon is caused to combine with hydrogen to form methane in an attack zone, and the methane is then caused to flow from the attack zone to a regeneration zone where it is cracked into carbon and hydrogen.
