In this beginning of year, 37 tons of EDF spent fuels were treated, with the aim of their recycling. The UP2 800 plant is at present in operation and the UP3 plant is in the shutdown.
(1)The fission products (ultimate residues of spent fuel) are incorporated in heated glass to approximately 1100°C. The whole is poured in stainless steel containers. The fission products are an integral part of stable, compact and resistant glass. This process is called vitrification.
(2)The compacted waste corresponds to the metallic structures of spent fuels, which once compacted, allow to divide by 5 the volume of the ultimate waste.
