Abstract

L'invention concerne un procédé de récupération de matières combustibles à partir d'assemblages combustibles nucléaires irradiés. Le dit procédé consiste à mettre la gaine des éléments d'un assemblage combustible nucléaire irradié en contact avec un agent de fragilisation qui réagit avec le métal de la gaine, de manière à le fragiliser, puis à désagréger ladite gaine fragilisée. Application à la récupération d'un combustible nucléaire à partir d'assemblages combustibles irradiés.
