PROCESS FOR THE PREPARATION OF URANIUM OXIDE POWDER (S), AT LEAST ONE MINOR ACTINIDE AND POSSIBLE PLUTONIUM ACTINIDE |
| abstract |
The invention relates to a method for preparing a powder based on oxide (s) comprising uranium, at least one minor actinide and optionally plutonium comprising the following steps: a) a step of adding at least one monomer to an aqueous solution comprising nitrate ions and comprising uranium, at least one minor actinide and optionally plutonium, said monomer comprising at least one ethylenic group and at least one polar group capable of forming hydrogen bonds ; b) a step of obtaining a gel trapping said aqueous solution by polymerization of the monomer or monomers added in a); c) a step of obtaining a xerogel comprising uranium nitrates, at least one minor actinide and optionally plutonium by dehydration of the gel obtained in b); d) a step of obtaining said powder by heat treatment of the xerogel obtained in c). |
