Abstract

Procédé pour permettre la récupération des actinides contenus dans des solutions résiduaires de carbonate de sodium contenant ces produits avec des produits de dégradation radiolytique et hydrolytique provenant d'agents d'extraction organophosphorés neutres eux-mêmes utilisés pour le retraitement de combustibles de réacteurs nucléaires irradiés. On acidifie la solution résiduaire par un acide minéral, formant ainsi une solution d'alimentation qu'on met en contact avec un agent d'extraction organique fortement polaire non miscible à l'eau qui extrait sélectivement les produits de dégradation, après quoi on sépare l'agent d'extraction chargé et la solution d'alimentation d'où l'on peut récupérer les actinides par simple évaporation.
