Abstract
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.
Claims4
In the reprocessing of nuclear fuel elements which contain carbon in addition to active material, the method of eliminating carbon therefrom which comprises transporting said carbon from a first zone containing said nuclear fuel elements to a second zone in a closed system by causing said carbon to combine with hydrogen to form methane in said first zone, causing said methane to flow from the first zone to the second zone, and then cracking said methane into carbon and hydrogen in said second zone.
