Effects of hydrodynamic chromatography on colloid-facilitated migration of radionuclides in the fractured rock

摘要

The performance assessment of high level radioactive waste disposal has emphasized the role of colloids in the migration of radionuclides in the geosphere. Previous literature [Nagasaki S, Tanaka S, Suzuki A. fast transport of colloidal particles through quartz-packed columns. J. Nucl. Sci. Technol. 1975;30(11):1136] indicates that owing to hydrodynamic chromatography the colloids velocity may not be equal to that of groundwater.
