Atmospheric releases from standardized nuclear power plants: A wind tunnel study. Fluid modeling report No. 12

Laboratory experiments were conducted to simulate radiopollutant effluents released to the atmosphere from two standard design nuclear power plants. The main objective of the study was to compare the dispersion in the wake of the standardized nuclear power plants with that in a simulated atmospheric boundary layer. A large meteorological wind tunnel was used to simulate a suburban atmospheric boundary layer. The model-prototype scale was 1:300 and the roughness length was approximately 1.0 m full scale. The model boundary layer simulated full scale dispersion from ground level and elevated release points over surfaces of comparable roughness length.
