Description

Technical field: [0001] The invention belongs to the technical field of radioactive material processing equipment, and relates to a radioactive organic waste processing device, which can safely and effectively convert organic components in radioactive organic waste into inorganic components. Background technique: [0002] During the operation of nuclear power plants, a large amount of organic radioactive waste containing 137Cs and 60Co will be produced, including waste engine oil, waste lubricating oil, waste resin and sludge. These organic radioactive wastes are not only radioactive, but also difficult to deal with. Among them, the treatment of radioactive waste resin It is the most difficult. One is that the waste resin enriches the radionuclide with a specific activity of 106-1013Bq / kg; the other is that the waste resin belongs to combustible radioactive organic matter containing sulfur and nitrogen, and incineration will produce corrosive and polluting Radioactive aeroso...
