Abstract
The present disclosure relates to a method for dehalogenation and vitrification of radioactive metal halide wastes. The dehalogenation method of radioactive metal halide wastes includes the following steps: mixing the radioactive metal halide wastes with oxalic acid, and performing a thermal treatment to remove halogens from the radioactive metal halide wastes. The vitrification method includes a following step: immobilizing the dehalogenated wastes treated by the dehalogenation method of radioactive metal halide wastes into a vitrified form by adding glass additives. The benefits of the method for dehalogenation and vitrification of radioactive metal halide wastes provided by the present disclosure include not only low dehalogenation temperature, high dehalogenation efficiency and high waste loading in the vitrified form, but also no new substances introduced after dehalogenation, which is easy to be integrated with the existing vitrification process. Therefore, the present disclosure shows a promising application.
