Radioactive waste disposal process geological structure for the waste disposal

Creators

Description

The process described here consists to carry out the two phases of storage operation (intermediate and definitive) of radioactive wastes (especially the vitrified ones) in a geological dispositif (horizontal shafts) at an adequate deepness but suitable for a natural convection ventilation with fresh air from the land surface and moved only with the calorific heat released by the burried radioactive wastes when the radioactive decay has reached the adequate level, the shafts are totally and definitely occluded

Abstract (French)

Le procede objet de l'invention consiste a effectuer les deux operations de stockage interimaire et de depot definitif de dechets radioactifs, notamment vitrifies, dans une installation geologique a pronfondeur suffisante et neanmoins apte a etre ventilee par convection naturelle d'air frais provenant de la surface du sol et mis en mouvement uniquement par l'energie calorifique liberee par les dechets radioactifs enfouis dans le sol. Lorsque la decroissance radioactive a atteint le taux souhaite, on obture le site completement et de facon definitive
