Abstract
Procédé pour l'élimination de déchets synthétiques pulvérulents et radioactifs, qui, séché, sont, dans un malaxeur, mélangés à une masse thermoplastique puis, par une ouverture de sortie du malaxeur, déversés dans un récipient de stockage définitif, les gaz ou les vapeurs étant extraits des dômes de dégazage. Les déchets séchés et fluides sont, par un mouvement mécanique, amenés au malaxeur 10 par un tube de dosage placé dans le dôme de dégazage 18 le plus proche de l'ouverture de sortie 13 et le tube de dosage est au moins momentanément soumis à l'action d'un gaz de balayage dirigé vers le malaxeur 10. Ce procédé est en particulier destiné aux déchets synthétiques constitués par des matériaux filtrants utilisés dans les installations nucléaires.
