Abstract

L'invention concerne un type perfectionné de matériau écran anti-radiations ainsi que des typess systèmes de stockage de matériaux radioactifs à base de ce matériau. Le matériau de protection "PYRUC", à base d'un composé d'uranium pyrolitique, est formé, de préférence, par traitement thermique et/ou sous pression d'un matériau précurseur comprenant des microsphères d'un composé d'uranium, tel que le dioxyde ou le carbure d'uranium, et d'un liant approprié. Le matériau de protection PYRUC offre une protection contre les rayonnements, des caractéristiques thermiques, une facilité d'utilisation accrues et se caractérise par un coût réduit par rapport à d'autres matériaux de protection. Le matériau de protection peut être utilisé pour fabriquer des systèmes de confinement, des porte-conteneurs, des structures de protection et des zones de stockage confinées, systèmes qui peuvent tous être utilisés pour le stockage de déchets radioactifs. Le système de protection préféré se présente sous la forme d'un conteneur pour le stockage, le transport et l'évacuation de déchets radioactifs. En outre, l'invention concerne également des procédés perfectionnés de préparation de microsphères de dioxyde et de carbure d'uranium destinées à être utilisées dans les matériaux de protection contre les rayonnements.
