METHOD FOR PRODUCING OXYHALOGENIDE, AND / OR ACTINIDE OXIDE (S), AND / OR LANTANIDE (S) FROM A MEDIUM CONTAINING AT LEAST ONE ONE MELT SALT

摘要

1. A method of producing oxychloride and / or oxide of actinide (s) and / or lanthanide (s) from chloride of actinide (s) and / or lanthanide (s) present in a medium containing at least one molten salt such as chloride, said method comprises the step of bringing said chloride of actinide (s) and / or lanthanide (s) present in said medium containing at least one molten salt of a chloride type into contact with a moist inert gas. A method according to claim 1, characterized in that the molten salt of the chloride type is selected from alkali metal chlorides, alkaline earth metal chlorides and mixtures thereof. A method according to claim 1 or 2, characterized in that the medium containing at least one molten salt is a mixture of lithium chloride and calcium chloride. A method according to claim 1 or 2, characterized in that the inert gas is a noble gas. A method according to claim 1 or 2, characterized in that the inert gas is argon. A method according to claim 1 or 2, characterized in that the inert gas is nitrogen. A method according to claim 1 or 2, characterized in that the actinide (s) are selected from uranium, plutonium, thorium, minor actinides and mixtures thereof. A method according to claim 1 or 2, characterized in that the step of bringing into interaction is carried out by bubbling a moist inert gas in a medium containing at least one molten salt into which actinide (s) and / or lanthanide (s) chloride are introduced. . A method according to claim 1 or 2, comprising, before the step of bringing into interaction, the step of obtaining a medium containing at least one molten salt in which actinide (s) and / or lanthanide (s) chloride is present. The method according to claim 1 and�
