Application of the sorting technology for decommissioned radioactive waste in an urban radioactive waste repository / 中国辐射卫生

ABSTRACT

Objective To establish a radioactive waste sorting process. Methods According to the current laws, regulations, standards, waste minimization requirements, and domestic good practices, the non-radioactive waste and radioactive waste were distinguished, and the radioactive waste was further sorted according to the different subsequent disposal methods of radioactive waste. The precautions for each step of the sorting process were described in detail. Results This process has been used in sorting decommissioned radioactive waste in an urban waste repository and achieved good results. Approximately 83 tons of radioactive waste and 1173 waste radioactive sources were sorted. Conclusion Good radioactive waste sorting technology can not only distinguish between radioactive and non-radioactive waste, but also facilitate the subsequent disposal of radioactive waste, which minimizes radioactive waste and protects staff and the environment.
