Title
(EN) METHOD FOR SEPARATING TRITIATED WATER FROM LIGHT WATER
(FR) PROCÉDÉ DE SÉPARATION D'EAU TRITIÉE ET D'EAU LÉGÈRE
(JA) トリチウム水の軽水からの分離方法
Abstract
(EN) Provided is a method for industrially separating tritiated water from light water, said method comprising, in the following order: a step in which, by adding heavy water to a liquid mixture containing tritiated water and light water, and, under conditions for forming a gas hydrate of the heavy water and/or of the tritiated water and conditions for maintaining the light water in a liquid state, forming a gas hydrate containing the tritiated water and the heavy water in a crystal structure, the tritiated water and the heavy water are removed from the light water; and a step in which, under conditions for forming a gas hydrate of the tritiated water and conditions for maintaining the heavy water in a liquid state, a liquid mixture, which is obtained by breaking down the structure of the gas hydrate containing the tritiated water and the heavy water and which contains the tritiated water and the heavy water, is made to form a gas hydrate containing the tritiated water in a crystal structure, such that the gas hydrate is separated from the heavy water, after which the tritiated water is collected from the heavy water by breaking down the structure of the gas hydrate containing the tritiated water.
(FR) L'invention concerne un procédé de séparation industrielle d'eau tritiée et d'eau légère, ledit procédé comprenant, dans l'ordre suivant : une étape dans laquelle, par l'ajout d'eau lourde à un mélange liquide contenant de l'eau tritiée et de l'eau légère et, dans des conditions permettant de former un hydrate de gaz de l'eau lourde et/ou de l'eau tritiée et des conditions permettant de maintenir l'eau légère dans un état liquide, la formation d'un hydrate de gaz contenant l'eau tritiée et l'eau lourde dans une structure cristalline, l'eau tritiée et l'eau lourde sont enlevées de l'eau légère; et une étape dans laquelle, dans des conditions permettant de former un hydrate de gaz de l'eau tritiée et des conditions permettant de maintenir l'eau lourde dans un état liquide, un mélange liquide, qui est obtenu par décomposition de la structure de l'hydrate de gaz contenant l'eau tritiée et l'eau lourde et qui contient l'eau tritiée et l'eau lourde, est amené à former un hydrate de gaz contenant l'eau tritiée dans une structure cristalline, de façon telle que l'hydrate de gaz est séparé de l'eau lourde, ce après quoi l'eau tritiée est récupérée à partir de l'eau lourde par décomposition de la structure de l'hydrate de gaz contenant l'eau tritiée.
(JA) 工業的にトリチウム水の軽水からの分離方法を提供する。 トリチウム水と軽水を含む混合液に、重水を添加し、重水及び/又はトリチウム水のガスハイドレートの形成条件下であって且つ軽水の液体状態を維持する条件下で、トリチウム水と重水とを結晶構造中に含むガスハイドレートを形成することにより、トリチウム水及び重水を軽水から除去する工程と、トリチウム水と重水とを含むガスハイドレート構造を壊して得られる、トリチウム水と重水を含む混合液を、トリチウム水のガスハイドレート形成条件下であって且つ重水の液体条件を維持する条件下で、トリチウム水を結晶構造中に含むガスハイドレートを形成して重水から分離した後、トリチウム水のガスハイドレート構造を壊して、トリチウム水を重水から収集する工程を、この順序で包含する。
