    1464316 Processing radioactive waste COMMISSARIAT A L'ENERGIE ATOMIQUE 20 Feb 1975 [28 Feb 1974] 7175/75 Heading G6R Radioactive waste and glass pieces are continuously fed to a kiln where they are mixed and heated as they pass through the kiln, so that the radioactive waste gradually becomes incorporated by deposition on the glass pieces. As shown, glass pieces are introduced at 8 and liquid radioactive waste at 14 into heated rotating stainless steel drum 3 which is slightly inclined to the horizontal. The temperature at the inlet may be 120‹ C. and at the outlet 400‹ C. The mixture leaves at 25 and passes to a melting furnace to form a vitreous mass incorporating the radioactive material and suitable for storage.

    to the output of the calciner, where the temperature is.
    A homogeneous mixture comes out of the calciner, which is a piece of glass covered with burnt radioactive waste. This mixture is emitted by gravity from the calciner and is fed into the smelter of a glass melter.
    : Due to the mobility of the layer of the mixture obtained, no calamines are formed in the calciner, which are capable of clogging it, it is not necessary to use mechanical means for cleaning the calciner, which will show the performance of the method for preparing the charge.
