Modeling radioactive pollution of atmosphere in region of the Volgodonsk atomic power station

Work is devoted to development of economic difference schemes for mathematical modeling radionuclide pollution in an atmosphere. The distribution of Kr-85 activity from a point source is calculated in view of influence of a relief on transport of a radioactive cloud. The data received as a result of modeling and computational experiments allow analyzing ecological safety of normal working mode and design-basis accident of the Volgodonsk atomic power station.
