Validation, training and uncertainty study experiments for real-time atmospheric dispersion models

The objective of this project is to quantify and assess uncertainties likely to arise during nuclear accidents involving a near-site atmospheric dispersion scenarios. Full scale aerosol-plume dispersion experiments were performed over various types of terrain, for a variety of different atmospheric conditions, including nonidealized but realistic dispersion events occurring during transitional (time-changing) meteorology. The final results will consist of sets of 'Reference and Validation Data', applicable as case studies for real-time dispersion models, and will include experimental data suitable for training and evaluation relevant for nuclear accidental releases.
