Advanced Atmospheric Dispersion Modelling and Probabilistic Consequence Analysis for Radiation Protection Purposes in Germany
Currently within the licensing procedure of nuclear facilities in Germany, atmospheric dispersion calculations are still predominantly based on the simple Gaussian plume approach. Advanced model systems consisting of a diagnostic flow model together with a Lagrangian particle simulation model, as e.g. described in a guideline of the German Association of Engineers (VDI 3945 part 3)1, have less restrictions with respect to terrain effects, source configuration and nonstationary conditions.
