Abstract | A storage apparatus is provided for dry storage of radioactive nuclear waste. The storage apparatus comprises a sealed canister containing the radioactive nuclear waste and an outer ventilated metal storage overpack (VMSO). The VMSO has a plurality of vents to enable ambient air flow through the VMSO and around the canister to thereby dissipate heat from the canister. The VMSO has a side wall having an inner metal layer and one or more sets of alternating layers. Each set includes a neutron absorbing layer adjacent to another metal layer so that neutron absorbing and metal layers alternate throughout the side wall.
Cette invention concerne un appareil de stockage conçu pour stocker à sec des déchets nucléaires radioactifs. L'appareil de stockage comprend une cartouche scellée contenant les déchets nucléaires radioactifs et un chemisage externe de stockage métallique aéré (VMSO). Le chemisage de stockage métallique aéré a une pluralité d'évents pour permettre un écoulement d'air ambiant à travers le chemisage de stockage métallique aéré et autour de la cartouche de sorte à dissiper la chaleur provenant de la cartouche. Le chemisage de stockage métallique aéré a une paroi latérale ayant une couche métallique interne et un ou plusieurs ensembles de couches alternées. Chaque ensemble comprend une couche absorbant les neutrons adjacente à une autre couche métallique de sorte que les couches absorbant les neutrons et les couches métalliques s'alternent sur toute la paroi latérale. |
