A Numerical Study of Atmospheric Dispersion in the Area of Nuclear Power Plant Dayawan
大亚湾核电站厂址区域大气扩散研究

A dynamic diagnostic model based on hydrostatic equilibrium was applied to simulate meteorological fields in the area of Nuclear Power Plant Dayawan, dynamic and thermal effects of non-homogeneous underlying surface upon wind field were investigated Numerical experiment shows that, this model can simulate basic characteristics and variation rules of local terrain-induced circulation very well With simulated meteorological fields, tempo-spatial distribution of pollutant and its deposition amount were studied by using Monte Carlo model for multiple sources Simulated results assert that, Monte Carlo model for multiple sources can simulate non-homogeneity and non-stability of atmospheric parameters under influences of land-sea and mountain-valley circulation
