very low level waste; landfill; migration prediction
Based on the brief introduction to the characteristics of the site of a very low level waste landfill,the main parameters selected as well as the model for the prediction of radionuclide migration,this paper focused on the migration of 3 H,90 Sr in both aquifer flow water and flow aeration in the landfill.Through the simulated migration prediction and analysis,the migration pattern of 3 H,90 Sr in a specific site was revealed,which provided the basis for the safety assessment of a site.
