(57) Abstract:
(EN): The present invention provides a disposal container for spent nuclear fuel. The disposal container includes: a metal container (11) in which spent nuclear fuel can be loaded; a ceramic member (20) disposed on the outer surface of the metal container (11); and a polymer member (30) disposed on the outer surface of the ceramic member (20). The present invention provides a disposal container for spent nuclear fuel, which has excellent corrosion resistance and durability, and excellent adhesion between dissimilar materials of metal, ceramic, and polymer, and can improve ease of handling and workability of the container.
(FR): La présente invention concerne un conteneur d'élimination de combustible nucléaire irradié. Le conteneur d'élimination comprend : un conteneur métallique (11) dans lequel un combustible nucléaire irradié peut être chargé ; un élément céramique (20) disposé sur la surface externe du conteneur métallique (11) ; et un élément polymère (30) disposé sur la surface externe de l'élément céramique (20). La présente invention concerne un conteneur d'élimination de combustible nucléaire irradié, qui présente d'excellentes propriétés de résistance à la corrosion, de durabilité, et d'adhérence entre différents types de matériaux tels que le métal, la céramique et le polymère, et qui peut faciliter la manipulation et l'utilisation du conteneur.
