Résumé
Abstract

Le but d'un site de stockage profond est de pouvoir isoler les déchets radioactifs de l'homme et son milieu environnant. Si le processus d'isoler ces déchets est, pour une raison on une autre, interrompu, les substances radioactives devraient être retardeés. Le conteneur est l'une de plusieurs barrières qui fonctionnent de façon à isoler les déchets et dans le cas échéant retarder le transport des nuclides radioactifs. Pour les déchets de faibles et moyennes activités, quatre conteneurs standardisés en métal et en ciment sont selectionnés. Les combustibles usés sont placés dans un conteneur en fonte pour fournir une résistance mécanique, le tout sera en suite placé dans un conteneur en cuivre qui résiste à la corrosion. Le conteneur sera placé dans un stockage profond qui est en cours d'être sélectionné en Suède. Cet article est particulièrement centré sur la mise au point des conteneurs.

The purpose of a disposal is to isolate the radioactive waste from man and the environment. If the isolation is broken, the leakage and transport of radioactive substances must be retarded. The package is one of several barriers, used to achieve these two main functions. For short-lived, low and intermediate level waste four standard containers of steel and concrete are used. Spent fuel will be placed in a canister consisting of a pressure-bearing insert of cast nodular iron and an outer corrosion barrier of copper before it is deposited in a deep geological repository. In particular, the development of a high integrity copper canister for the isolation of spent nuclear fuel is described in this paper.
