Le système de conteneurs (3) selon l'invention comprend un premier conteneur (1) et un deuxième conteneur (2). Le premier conteneur (1) entoure au moins partiellement le deuxième conteneur (2) de sorte que les deux conteneurs (1, 2) sont au moins partiellement emboîtés l'un dans l'autre, le deuxième conteneur (2) contient un matériau radioactif et/ou toxique et un espace intermédiaire (4) dans lequel une matière de charge (5) peut être coulée et durcie est ménagé entre le premier conteneur (1) et le deuxième conteneur (2). L'invention fournit ainsi un système de conteneurs pour le stockage intermédiaire ou définitif de déchets radioactifs et/ou toxiques qui est apte à isoler les déchets radioactifs et/ou toxiques ou à assurer le blindage, tout en garantissant une récupération à long terme.
