This paper presents work done to improve the representation in European decision support tools of physico-chemical forms of radiocontaminants released to the atmosphere from a major nuclear power plant accident. The task is to accommodate those types of scenarios where fuel particles are at play. A methodology with associated parameters has been developed to improve modelling of the aerodynamic particle characteristics, and resultant deposition relations on different surface types, as well as estimates of resultant post-deposition environmental contaminant mobility/forced decontamination.
Key words: NPP accident / emergency / decision support / atmospheric release / aerosols
