Abstract
Reconditioning ammonium nitrate-containing radioactive filtrates as produced in AUC or AU Pu C process by feeding preheated filtrate into the cathode chamber of an electrolysis cell containing boiling ammonium nitrate solution. The filtrate is brought to the boiling temperature with the assistance of the joulean heat of the electrolysis current. Ammonium carbonate and free NH.sub.3 in the filtrate are given off as gaseous CO.sub.2 and NH.sub.3 and steam and electrolytically formed NH.sub.3. The uranium and/or plutonium originally in solution as carbonate complexes is precipitated and separated by continuous circulation of the cell contents through a filter as well as electrolytically at the cathode.
