Numerical modelling of the radioactive pollution in case of NPP accident
Description
A model for long-range transport and diffusion of pollutants is briefly described. The model is adapted for evaluation of the radioactive pollution concentrations in case of NPP's accident. This is a Lagrangian- Eulerian model, which uses only standard meteorological information: the temperature at surface and 850 h Pa level and the wind at 850 h Pa. The model could be applied for a large spectrum of problems. As an illustration of its possibilities a numerical simulation of the Chernobyl accident is carried out. The results show the fields of concentrations of Cs-137 for a 7-day period from the beginning of the accident and for the territory, covering a large part of Europe. (author)
