Description

The in-situ experiment on the colloids and radionuclide retardation (CRR experiment) in the Grimsel Test Site in Switzerland was performed, as the international research program managed by NAGRA, Switzerland. This paper presents the modeling results of the CRR experiment by numerical code COLFRAC which describes colloid-facilitated solute transport in fractured media. Moreover, we estimated effects of microorganism as a colloid on radionuclide migration by using the COLFRAC code. The results indicated that the migration of radionuclide is enhanced when radionuclide is captured in the microorganism, and the migration of radionuclide significantly depends on concentration of microbes.
