Abstract
On chauffe à environ 95 degrés C, à travers un chauffe-eau électrique instantané 1, la solution de départ en libérant ainsi CO2 et NH3 , puis, à 50-55 degrés C et avec accélération par la présence de germes cristallins, on fait précipiter en 3, à partir de la solution restante, sous amenée de NH3 , air et H2 O2 , les composés d'uranium (2 NH 4 F.UO4 ) qu'elle renferme et on les oxyde par vapeur d'eau en U3 O8 sans fluor dans un four 6 à 800 degrés C. L'invention intéresse particulièrement le retraitement de l'uranium usagé.
