Abstract

Cette invention se rapporte à un conteneur ayant une capacité d'au moins 0,05 cm3 environ, qui comporte un récipient en céramique (6b) ayant une épaisseur de paroi d'au moins 2,5 cm, ce conteneur étant fabriqué par un procédé de cuisson aux micro-ondes. Un système de confinement est également présenté pour les matériaux ou les déchets dangereux, ce système comportant: (a) un récipient en céramique cylindrique, hélipsoïdal ou sphérique (6b), ayant une épaisseur de paroi d'au moins 2,5 cm, des fibres de renforcement optionnelles dans ces parois; et (b) un couvercle en céramique (6a) ayant une épaisseur d'au moins 2,5 cm, des fibres de renforcement optionnelles, ce couvercle en céramique pouvant être joint sans couture et de façon non poreuse au récipient (7) par micro-ondes, après que les matériaux ou les déchets dangereux ont été placés dans le récipient. Une couche intermédiaire en matériau de blindage nucléaire (8) entourant le premier système de confinement et au moins un système de confinement en céramique additionnel (12a) entourant ladite couche intermédiaire sont également prévus pour des matériaux ou des déchets nucléaires.
