Abstract
The paper describes a numerical scheme implemented in the GeRa code to solve the problem of radionuclide transport in porous medium taking into account radioactive decay chains. It is based on a scheme of splitting by physical processes and the use of separate modules for solving transport and radioactive decay chain problems. Verification of the numerical scheme was performed using an analytical solution for a specific case of the problem formulation in a homogeneous porous medium. The study explores the error introduced into the numerical solution by the use of the splitting scheme. The study provides recommendations regarding the selection of appropriate parameters for the numerical scheme to calculate the transport of nuclide chains with different sorption properties.
