3-D numerical modelling of mud and radionuclide transport in the Chernobyl Cooling Pond and Dnieper - Boog Estuary

The 3-D model THREETOX, that includes modules of hydrodynamics, sediment and pollutant transport, was developed to simulate the radionuclide fate in a deep stratified water body. This paper describes the methodology and results of simulation of the radionuclide transport and fate in the cooling pond of the Chernobyl Nuclear Power Plant and in the Dnieper – Boog Estuary. The analysis of the efficiency of the chosen sediment transport model is based on the use of radionuclides from the Chernobyl accident as tracer.
