Hydrodynamic model of radionuclide dispersion during normal operation and accident of Bushehr nuclear power plant

Abstract Several numerical models have been developed to simulate the dispersion of radionuclides in the aqueous environments. In this research, the 2-dimensional depth averaged hydrodynamic model is applied to obtain the current components in a part of Persian Gulf taking into account the tidal effects. The hydrodynamic equations solved by a finite differential approach. In this model the time step is 5 s (totally for 3 days) and spatial step is 10 Km. From the mainstream in the study area, it is also found that the velocity of water in the central region and near Iran's shore lines is higher than the other places. Using the average value of the speed from hydrodynamic equation, the concentration of some radioactive elements is also obtained by CROM tool.
