Installation for vitrification of liquid radioactive wastes, cooled discharged unit and cooled induction melter for the installation

An installation for vitrification of liquid radioactive wastes comprising

• a vessel for receiving a dosed portion of homogeneous liquid radioactive wastes and collecting concentrated homogeneous liquid radioactive wastes, the vessel being linked to a collector of liquid radioactive wastes and having first and second inputs and an output,
• an evaporator having an input, provided with a gate and coupled to said output of said vessel to receive radioactive wastes, and having a first output coupled to second input of said vessel to receive radioactive wastes, and a second output,
• a separator for separating droplets of liquid from the steam-gaseous mixture, having an input connected to said second output of said evaporator, and having an output,
• a condenser for condensing steam having an input coupled to said output of said separator, and an output for the discharge of a condensate,
• a mixer provided with a means for mixing components, having an input provided with a gate and connected to said output of said vessel to receive concentrated homogeneous liquid radioactive wastes, a second input, third input and output,
• a doser of vitrification agent additives, having an output coupled to said second input of said mixer,
• a doser of heterogeneous liquid radioactive wastes, connected by its output to said third input of said mixer,
• a vessel-accumulator provided with a means for homogenization of components, having an input coupled to said output of said mixer and an output,
• a vortex apparatus serving to process a mixture of liquid radioactive wastes in a vortex layer, having an input connected to said output of said vessel-accumulator, and an output provided with a doser,
• a water-cooled induction melter with a movable inductor, having a first input connected to said output of said doser of the vortex apparatus, a second input, a first output for discharge of obtained melt of vitrified radioactive wastes and a second output for discharge of waste gases,
• a means for filtering waste gas having successively mounted coarse filters and fine filters, having an input connected to said second output of said melter, and an output,
