Abstract

Process for the recovery and purification of spent nuclear fuels, in which the used nuclear fuels are dissolved first with the aid of a solvent and then the materials are obtained from the solution by extraction, characterized in that the nuclear fuel, in ground form, preferably ground, in a solution tank, which works continuously, it is taken to form a solution and the materials, which are in the solution, are continuously separated from the solution in an extraction column composed of mixing centrifuges.
