ABSTRACT:
In the manufacture of nuclear fuel tubes spent etching solutions containing nitric acid, zirconium, and hydrofluoric acid are produced as waste. A serial treatment process is employed to recover the zirconium and to restore the solution to the desired acid concentration. These processes include solvent extraction for zirconium removal and aqueous removal using evaporation or distillation.
