Abstract
The Marcoule Vitrification Plant (so-called A.V.M.) operating since June 1978 is based on the French continuous technique and produces a glass through a calcination step, operated in a rotary kiln and a melting step in a metallic pot. The plant was designed for a maximum flow-rate of 36 1 h of fission products solution converted into 15 to 18 Kg/h of glass. Every day a container loaded with approximately 360 Kg of glass is sealed and externally decontaminated — then it is stored in a nearby air cooled disposal facility. The amaunvof the released radioactive materials is low; the liquid wastes are concentrated and fed back. The possible solid wastes are cut and put in containers for subsequent melting. During the one year of fully radioactive work, 132 m 3 of fission products solution have been vitrified producing 60 tons of glass. A similar plant devoted to the La Hague reprocessing plant is being designed and is scheduled to be in operation in 1985.
