1. Introduction
Domestic radioactive waste is generated by nuclear power plants, the Korea Atomic Energy Research Institute and KEPCO Nuclear Fuel Company. Each organization has different waste classification criteria. There is also no established integrated waste classification standard.
2. Classification of Domestic Agency
2.1 Korea Atomic Energy Research Institute
As for the Korea Atomic Energy Research Institute, the decommissioning waste due to decommissioning of research reactors NO. 1&2, and the low and intermediate-level radioactive waste, generated by the operation of High Flux Advanced Neutron Application Reactor (HANARO), account for the most. Korea Atomic Energy Research Institute Radioactive waste classification standards (Table 1) are classified into combustible, non-combustible, organic waste, and inorganic waste.

2.2 KEPCO Nuclear Fuel Company
KEPCO Nuclear Fuel produces the nuclear fuel used in nuclear power plants, and the nuclear production process generates radioactive waste. It is classified into 8 types of waste according to the solid waste management procedure as shown in Table 2.

2.3 Korea Hydro & Nuclear Power Company
The miscellaneous solids, generated in the Hanbit NPP of Korea Hydro & Nuclear Power Co., Ltd., are classified as shown in Table 3 in consideration of the physical properties, density and amount of the waste, and substances subject to restricted disposal.

3. Conclusion
This paper investigated the classification standards and treatment methods according to the characteristics of the radioactive substances handled by each agency. These classification and treatment methods can be applied to the database when the radioactive waste tracking system is implemented in the future. It is expected that more efficient and safe WTS can be constructed by integrating the radioactive waste generated by each institution into the integrated WTS database input and field application.
