TRANSPORT PROCESS MODELING ASSUMING CHEMICAL INTERACTIONS IN THE GERA SOFTWARE

The paper considers a transport model with geochemical couplings implemented in the GeRa software. It evaluates the scope of application typical for such models focused on the safety assessment of nuclear facilities. The paper presents a few typical case studies to demonstrate the accountability of different chemical processes: ion exchange, surface complexation, dissolution and mineral phase precipitation. It overviews some typical radionuclide transport problems with an account taken of sorption, as well as the one of concrete decalcifi ation.

Keywords: geochemical modeling, radionuclide transport, software systems, seepage, radioactive waste.
