Description

Modelisation of liquid-liquid extraction systems used in nuclear industry allows the forecasting of chemical repartition in organic and aqueous phase and also adaptation of known processes to new conditions. After a brief review of the PUREX process extraction of nitric acid, uranyl nitrate and palladium nitrate are examined

Abstract (French)

La modelisation des systemes d'extraction liquide-liquide utilises dans l'industrie nucleaire permet de prevoir la repartition des especes chimiques dans les phases aqueuse et organique, donc de choisir des conditions optimales de separation. D'autre part, elle permet l'adaptation de procedes existants a de nouvelles conditions. Apres une breve revue du procede PUREX, on examine l'extraction de l'acide nitrique, du nitrate d'uranyle et de nitrate de palladium
