摘要： The invention relates to a method for co-precipitation (or simultaneous preparation) of at least one actinide in oxidation state (IV) with at least one actinide in oxidation state (III), in which a mixed solution of actinide(s) in oxidation state (IV) and actinide(s) in oxidation state (III) is prepared with addition of either a mono-charged cation which stabilises the oxidation states in the mixture, or a mono-charged cation with no stabilizing role for the oxidation states in the mixture and a solution containing oxalate ions is added to said mixture of actinides to produce a co-precipitation, or simultaneous precipitation of said actinides of oxidation state (IV) and (III) and a fraction of the mono-charged cation. According to another embodiment, a mixed solution of actinide(s) in oxidation state (IV) and actinide(s) in oxidation state (III) is prepared and a solution containing oxalate ions and a mono-charged cation is added to said mixture of actinides to produce the co-precipitation. The invention further relates to mixed actinide compounds from calcination of the precipitate above. Said mixed compounds such as oxides, carbides or nitrides are particularly of use in the production of nuclear fuel, for the production of transmutation targets or for the stable storage of nuclear material.

摘要： The invention concerns a method and a device for oxidising one or several actinides stabilised in reduced form by one or several anti-nitrous agents in concentrated nitric solution. The method consists in subjecting the actinide nitric solution to electrolysis in at least one anode compartment so as to selectively oxidise at least part of said solution anti-nitrous agent to obtain a first solution; subjecting a concentrated nitric acid solution to electrolysis in at least a cathode compartment of said electrolyser so as to form nitrous acid in said solution to obtain a second solution; mixing said first and second solutions.

摘要： Niobium (V) and tantalum (V) halides are converted to Nb₂O₅ and Ta₂O₅ that are free of detectable levels of halide in a two step process. In the first step, the metal halide is reacted with an alcohol and with a replacement species, such as ammonia, which reacts with the halide. This produces a metal alkoxide which is soluble and a halide salt of the replacement species which is insoluble in the alcohol and precipitates. After physically separating the alkoxide in alcohol solution from the precipitate, in a second step, the metal alkoxide is hydrolyzed with purified water to produce the oxide.
