Abstract

La présente invention concerne la désactivation en toute sécurité de réfrigérants métalliques liquides, tels que les métaux alcalins, utilisés dans des systèmes de réacteurs nucléaires, et leur mise sous forme d'un déchet solide jetable. Le métal (10) alcalin est dissout dans un liquide (14) ammoniacal, tel que l'ammoniac liquide anhydre, afin de former un mélange réactionnel comprenant des cations de métal alcalin et des électrons solvatés. Un agent (16) de précipitation qui s'ionise dans l'ammoniac liquide est introduit dans le mélange réactionnel afin de se combiner avec les cations de métal alcalin et/ou les électrons solvatés et former ainsi un sel de métal alcalin précipitant. En outre, il est possible de dissoudre le métal alcalin solide restant dans le système réfrigérant, après vidange initiale de ce métal, par circulation de liquide ammoniacal dans le système réfrigérant. La récupération de l'ammoniac liquide contenant le métal alcalin dissout est suivie de l'addition d'un agent de précipitation ionisable afin de former un sel de métal alcalin.
