"The project is aimed at the migration of long-lived radionuclides - transuranics of with high radiotoxicity (241Am) and some fission products (129I and 135Cs). The project is dealing with the experimental assessment of upward vertical and horizontal migration processes of the mentioned radionuclides in saturated conditions of soils and sediments and their modelling. Research activities in innovative ways are proposed as a part of this project, i.e., laboratory migration experiments of various designs with simultaneous evaluation of kinetic and thermodynamic aspects of processes with the aim of their quantification. Two classes of models (advection-dispersion and compartment) will be evaluated for this purpose from the point of view of their suitability and parametrical demand. The correlation of main parameters of soils and sediments with migration rates will be carried out and predictability of established models for different conditions will be assessed.
