| titleOfInvention | High temperature melt processing systems and methods for flammable and non-combustible radioactive waste |
| abstract | The present invention relates to a process for separating middle and lower flammable and nonflammable radioactive wastes generated from nuclear power plants and radioisotopes using engines and separately performing high temperature melting treatment suitable for them, The present invention relates to a system and a method for treating radioactive waste comprising a molten processing apparatus and an evacuation processing apparatus.n n n In the present invention, the combustible radioactive waste is pyrolyzed and calcined in a pyrolysis furnace, and then the calcined product is melted at high temperature together with borosilicate glass using an induction current-heated electric furnace to vitrify the organic material, thereby innovatively depressurizing and treating the radionuclide . The glassy solid formed at this time is very stable and environmentally friendly. The non-combustible radioactive waste can be melted at a high temperature using a plasma melting furnace to completely break down a trace amount of organic matter, stabilize the inorganic component, and confine the radionuclide in the slag. The slack sediments generated at this time are also very strong and stable and environmentally friendly.n n n Currently, the methods used for the treatment of medium and low level radioactive waste worldwide are vitrification of flammable wastes or treatment in one high temperature melting furnace without distinguishing between flammable and nonflammable. When organics and minerals are mixed in waste, they form stable molten In addition, there is a possibility that some radioactive nuclides may leak out even when the melt is disposed of at the repository, and secondary wastes are generated in the exhaust treatment system generated during the melting process.n n n In the present invention, the exhaust treatment apparatus for treating flammable, non-combustible radioactive waste in each of the furnaces and for treating the gas generated during the high-temperature melting safely treats the exhaust gas generated in the high-temperature furnace. The flammable and nonflammable radioactive secondary wastes generated in the exhaust gas treatment system are again an outstanding radioactive waste treatment system in which secondary wastes are not generated at all due to the high-temperature melting treatment in the melting furnace. |
