the invention concerns a method and a device for the disposal of a cation exchanger (3) contaminated with radioactive and inactive rations. The invention calls for the inactive cations which are not bivalent to be converted into anionic complexes and these complexes to be flushed out of the exchanger (3). Far this purpose, the cation exchanger (3) is connected to a feed line (4) for a complexing agent and to a discharge line (6).
L'invention concerne un procédé et un dispositif permettant d'éliminer un échangeur de cations (3) chargé en cations radioactifs et en cations inactifs. Il est prévu que les cations inactifs qui ne sont pas bivalents soient convertis en complexes anioniques et que ces complexes soient chassés hors de l'échangeur de cations (3). A cette fin, l'échangeur de cations (3) est raccordé à une conduite d'alimentation (4) pour agent complexant et à une conduite d'évacuation (6).
