Characteristics and disposal cases of associated radioactive waste residues in China
Abstract
The associated radioactive waste residue has characteristics of long half-life of nuclides, wide range of radioactive levels, and so on. There are many industries involved in associated radioactive waste in China with wide sources, large types and quantities, hence restrict the healthy development of the industry. This study aims to propose effective safety disposal measures suitable for the complex physical and chemical properties of such waste residues, large differences in regional distribution and disposal status. Through comparison and analysis with hazardous waste, medium and low level radioactive waste, uranium mining and smelting waste, the technical support for the regulatory concept of associated radioactive waste residue was provided. The current disposal methods, design requirements, applicable scenarios, advantages-disadvantages and application examples of this kind of waste residue were systematically introduced, and the disposal strategies of associated radioactive waste residue were suggested. Meanwhile, a typical case of a regional disposal site project was taken as example, the characteristics of the project and waste residue were deeply analyzed, and the countermeasures were given to provide reference for relevant disposal work. Finally, based on above work, some suggestions are put forward to promote the final disposal of associated radioactive waste residue in China.
