摘要：

In order to solve the difficulties in processing low-level radioactive resin, and to improve the volume-reducing effect and stability of the waste body, we introduced a high temperature plasma molten method to pyrolyze the organic composition in resin and to melt the inorganic components. Aiming at spent ion exchange resin, we developed a cold experiment platform for plasma high-temperature incineration. Furthermore, we investigated the characteristic and simulated waste incineration, as well as the techniques involved in the process. The results indicate that the plasma high-temperature incineration technology can decompose the spent ion exchange resin completely, with a volume reducing factor up to 53.5 and a compressive strength of glass more than 74 MPa. The contamination of nitrogen oxides is 20~300 mg/m3 in off-gas, and that of sulfur dioxide is 0~95 mg/m3, which meet the requirements of the Pollution Control Standard for Hazardous Wastes Incineration. It is concluded that using plasma technology can achieve volume reduction and stabilization treatment of radioactive waste resin by having radioactive nuclide solidified in glass to stabilize the performances of solidified body.
