Abstract

Il est divulgué une pastille de combustible nucléaire à base de dioxyde d'uranium qui comprend des microcellules métalliques ayant simultanément une grande capacité de protection pour les produits de fission et une grande conductivité thermique, agencées dans la pastille de combustible nucléaire pour piéger les produits de fission, de manière à empêcher l'extraction des produits de fission dans des conditions de fonctionnement normal et à réduire la température d'un combustible nucléaire pour améliorer les performances du combustible nucléaire, uniquement pour empêcher l'extraction des produits de fission radioactifs dans l'environnement dans des conditions d'accident afin d'améliorer la stabilité de la pastille de combustible nucléaire. Sa méthode de fabrication est également divulguée.
