Abstract

Process of treatment or regeneration of an aqueous solution of spent fuel of nuclear reactors and of separation of the fission products, characterized in that said solution is subjected to an extraction in a single cycle with an organic solvent, in the presence of an aqueous salification agent for producing an aqueous stream of extract containing uranium and when molds a fission product chosen from ruthenium, and zirconium and niobium; said aqueous extract stream being dehydrated to obtain anhydrous solids and said solids fluorinated to obtain the corresponding fluorides; and by the relatively low boiling point uranium fluoride separation of the relatively high boiling point fluoride from the fission product.
