PROCEDES DE PREPARATION D'UN OXALATE D'ACTINIDE(S) ET DE PREPARATION D'UN COMPOSE D'ACTINIDE(S)
摘要:
The invention relates to a method for preparing an oxalate of one or more actinides, including: precipitating said actinide or coprecipitating the actinides in the form of oxalate particles by contacting an aqueous solution containing the actinide(s) with an aqueous solution of oxalic acid or an oxalic acid salt; collecting the resulting oxalate particles; characterised in that the precipitation or coprecipitation is carried out in fluidised bed. The invention also relates to a method for preparing an oxide, carbide, or nitride actinide oxalate using said method. The invention can be used for processing and recycling nuclear fuel.
