Abstract
Fourneau destiné à réduire le volume de pièces usées ayant été irradiées. Une couche tampon 75 revêtant le fond de la cuve 51 du fourneau comporte une surface supérieure 75b dans laquelle est réalisée une cavité 76 dans laquelle les déchets radio-actifs subissent la fusion. Ces déchets tombent dans cette cavité par un cylindre guide 80 dans ladite cavité et cette couche tampon évite les dégâts pouvant être causés à la cuve par le choc pouvant être produit par les pièces arrivant en chute libre. Application par exemple à la réduction en grenaille ou en petits lingots de pièces ou de revêtements inutilisables provenant de centrales nucléaires.Furnace intended to reduce the volume of worn parts having been irradiated. A buffer layer 75 coating the bottom of the vessel 51 of the furnace comprises an upper surface 75b in which is formed a cavity 76 in which the radioactive waste undergoes fusion. This waste falls into this cavity through a guide cylinder 80 in said cavity and this buffer layer prevents damage that may be caused to the tank by the impact that may be produced by the pieces arriving in free fall. Application for example to the reduction into shot or into small ingots of unusable parts or coatings coming from nuclear power plants.
