Abstract

Ce procédé, pour le traitement des solutions contenant du nitrate d'ammonium, qui contiennent encore une faible quantité d'ions métalliques lourds U, Pu opère selon la figure et suivant le principe de l'électrolyse à contre-courant en effectuant une séparation spatiale des ions NH4 d'une part et des ions NO3 d'autre part, en chassant le NH 3 en 5 par augmentation de la température, en éliminant le NO3 sous forme de HNO3 4 ainsi que les ions métalliques lourds 7 qui se rassemblent, en vue d'un traitement ultérieur ou d'un recyclage. Utilisation de ce procédé pour supprimer les risques d'explosion inhérents au traitement des solutions de nitrate d'ammonium.
