Classical Gaussian approach in the form of hybrid puff-plume segmented model SGPM is introduced for simulation of pollution dissemination in the atmosphere. The ingestion pathway is modeled dynamically. The system architecture consists of the inner kernel designated for deterministic calculations and outer probabilistic shell, which ensures application of probabilistic approach in the consequence assessment. Propagation of uncertainties through the model towards the output values of interest is realized through the multiple recalling procedure of the inner kernel, which is optimized for such intensive Monte Carlo (MC) computations. cav_un_auth*0271370 Probability Safety Assessment 2011 Wilmington, NC 13.03.2011-17.03.2011 US 2012 JF http://hdl.handle.net/11104/0006398 2011 cav_un_epca*0358450 International Topical Meeting on Probability Safety Assessment and Analysis 978-1-61782-847-8 1 12 Wilmington American Nuclear Society 2011
