Abstract

L'invention a trait à un procédé de préparation d'une composition comprenant de l'uranium et au moins un élément choisi parmi le plutonium, au moins un actinide mineur et des mélanges de ceux-ci, une partie au moins de l'uranium étant sous forme d'octaoxyde de triuranium U3O8 comprenant une étape de traitement thermique d'au moins un complexe de coordination comprenant de l'uranium et au moins un élément choisi parmi le plutonium, au moins un actinide mineur et des mélanges de ceux-ci dans des conditions suffisantes pour obtenir une formation d'octaoxyde de triuranium U3O8. Utilisation de la composition obtenue pour la réalisation d'un combustible nucléaire à base d'une solution solide d'oxyde d'uranium et d'au moins un élément choisi parmi le plutonium, le thorium, au moins un actinide mineur et des mélanges de ceux-ci.
