Title (EN) CONTAINMENT CASK FOR DRUM CONTAINING RADIOACTIVE HAZARDOUS WASTE
(FR) CHÂTEAU DE CONFINEMENT POUR FÛT CONTENANT DES DÉCHETS RADIOACTIFS DANGEREUX
Abstract:
(EN) A containment cask for safely transporting and storing radioactive hazardous waste in a dry air environment. The cask comprises a single drum containing the radioactive hazardous waste, a sealed and shielded containment vessel containing the drum, and an outer container. The outer container can be in the form of an outer shield vessel (OSV) made from iron to provide further shielding. This outer container is appropriate for a drum having higher activity waste. The outer container can also be in the form of an overpack assembly that adds protection for atmospheric hazards, but adds little in terms of shielding. This outer container is appropriate for a drum having lower activity waste.
(FR) La présente invention concerne un château de confinement conçu pour transporter et stocker en toute sécurité des déchets radioactifs dangereux dans un environnement à air sec. Le château comprend un seul fût contenant les déchets radioactifs dangereux, une cuve de confinement étanche et blindée contenant le fût et un conteneur externe. Le conteneur externe peut se présenter sous la forme d'une cuve blindée externe (OSV) en fer destinée à assurer un blindage supplémentaire. Ce conteneur externe est approprié pour un fût contenant des déchets à haute activité. Le conteneur externe peut également se présenter sous la forme d'un ensemble de suremballage qui renforce la protection contre les risques atmosphériques mais est peu efficace en termes de blindage. Ce conteneur externe est approprié pour un fût contenant des déchets à faible activité.
