Abstract
The CERES platform developed by CEA to assess the atmospheric dispersion and the environmental impact has been coupled with the Model of Multiphase Cloud Chemistry (M2C2) developed by LaMP in order to take account of the chemical reactivity during dispersion. The method used consists to provide lookup tables of the concentration gradient issued by M2C2 to characterize the chemical reactivity in the atmosphere then correct each puff during atmospheric dispersion calculations. A case of NH3 release is presented and shows that NH3 concentration in the air is less important taking account of the chemical reactivity, NH3 undergoing photolysis and oxidation by radicals. Several tests are ongoing to validate the method and improvements have to be done to reduce approximations.
