Keywords:Low Level Radioactive waste, Radionuclide, Radioactive concentration, Near surface disposal, Safety assessment

In order to set the radioactivity of radionuclides in the low-level radioactive waste for study on near surface disposal, we improved technique to evaluate the radioactivity in consideration of the element composition of the structural materials and fuel in the reactor and the nuclide behavior, reflecting the latest disposal results and the analysis of element in the structural materials in the reactor.
