Two important factors that affect radionuclide transport in fractured rock media are matrix diffusion and matrix adsorption.In this study,we examined the influence of flow conditions on matrix diffusion and matrix adsorption in the fractured media.our study shows that the relative strength of fractured media.our study shows that the relative strength of fracture and matrix flow fraction configurations controls the effect of matrix diffusion and matrix adsorption on radionuclide transport.In a system dominated by fast fracture flow,the effect of matrix diffusion and matrix adsorption on radionuclide transport is minimal.On the other hand,in a system with less fracture dominated flow and strong fracture-matrix flow interactions,matrix diffusion and matrix adsorption plays a dominant role in retarding radionuclide movement in the fratured media.
