Mobility of plutonium is strongly affected by its oxidation state and surrounding environmental parameters in subsurface environment. Especially, the presence of Soil Organic Matter is known to make a significant effect on sorption and migration of plutonium. In this study, the behavior of plutonium is quantitatively examined using PHREEQC-2 thermodynamic modeling codes with verified set of experimental data. The contribution of individual soil component also is evaluated by numerical simulation using component additive approach.
