Abstract
La présente invention concerne un procédé de traitement des filtrats radioactifs. Le filtrat radioactif obtenu avec le procédé AUC est introduit dans une cellule d'électrolyse 1 contenant une solution de nitrate d'ammonium en ébullition, où il se dissocie. La vapeur d'eau, le CO2 et le NH3 qui se forment, évacués par la conduite 33, sont réintroduits dans le cycle du procédé AUC. Les composants radioactifs précités sont captés dans un filtre 5 et réintroduits dans le cycle de production. Utilisation de ce procédé pour récupérer les produits de décomposition du NO3 NH4 en éliminant les risques d'explosion de celui-ci.
