Thermodynamic analysis of the processes of plasma treatment of low-level radioactive waste in shaft furnaces

The thermodynamic aspects of the process of plasma treatment of radioactive waste in shaft furnaces were considered.

Description
Summary:The thermodynamic aspects of the process of plasma treatment of radioactive waste in shaft furnaces were considered. Thermodynamic simulation of the formation of pyrogas during plasma treatment of waste was carried using the example of “Piroliz” and “Pluton” pilot-commercial facilities for solid radioactive waste treatment. It was shown that the thermodynamic simulation method allows fairly adequately describing the changes in the composition of the pyrogas withdrawn from the shaft furnace at different waste treatment regimes. This offers a possibility of developing environmentally and economically viable technologies and small-sized low-cost facilities for plasma treatment of radioactive waste to be applied at currently operating nuclear power plants.
