Abstract:
The invention relates to a method for preparing a fuel based on oxide, carbide, and/or oxycarbide comprising uranium and at least one actinide and/or lanthanide component, comprising the following steps: a step for preparing a load solution consisting in a nitric solution comprising said actinide and/or lanthanide in the form of actinide and/or lanthanide nitrates and uranium as a hydroxylated uranyl nitrate complex; a step for passing said solution over a cation exchange resin comprising carboxylic groups, with which the actinide and/or the lanthanide in cationic form and the uranium as uranyl remain bound to the resin; a heat treatment step of said resin so as to obtain said fuel.
