TO THE NECESSITY OF TAKING INTO ACCOUNT THE DISPOSAL’S STRUCTURE WHILST FAR FIELD WASTE INPUT MODELING

Radionuclides from radioactive waste disposal in Nizhnekansky Rock Massif modeling is considered on the repository scale which allows for taking into account the structure of proposed facility. 3D numerical flow and transport model is developed using the GeRa code. The contaminant release across the model’s border is analyzed and the importance of repository construction features detailed consideration for dynamics of contaminant release into the far field is demonstrated.

 

Key words: nuclear waste disposal, mathematical modeling, geomigration.
