The level of pollution concentration to the archaeological site Viminacium caused by the stack of Kostolac B power plant is analyzed using CFD software. The wind is directed from the stack toward Viminacium-Archaeological Site, Therma and Viminacium - Museum. Three different meteorological conditions resulting in fanning, fumigating and looping plume are modelled. The temperature gradient as the most important factor defining the conditions of the atmosphere is included through the appropriate boundary conditions. It is shown that concentrations of the pollutants on the objects of Viminacium are very low. It can be attributed to the stack height and high temperature of the smoke at its exit. It also indicates that other sources of pollution such as open ash dumps and acid rain should be checked.
