In this paper, after a critical review on QRA uncertainties connected to consequence modeling, we consider an hazardous release of hydrochloric acid following an accidental loss of containment of a tank truck. After the source term characterization, we made a comparison of consequence results among different integral approaches, providing modeling for the combination of all physical phenomena involved after the release. The applicative phase of this work, representing its main appeal, is the validation of the simulation results against field data sets in the near field, directly collected during emergency response activities. Quantitative conclusions are drawn about the cross-check validation performed. At last, we provide some numerical examples on the proper model choice for atmospheric dispersion studies, depending on their main purpose.

Abstract

In this paper, after a critical review on QRA uncertainties connected to consequence modeling, we consider an hazardous release of hydrochloric acid following an accidental loss of containment of a tank truck. After the source term characterization, we made a comparison of consequence results among different integral approaches, providing modeling for the combination of all physical phenomena involved after the release. The applicative phase of this work, representing its main appeal, is the validation of the simulation results against field data sets in the near field, directly collected during emergency response activities. Quantitative conclusions are drawn about the cross-check validation performed. At last, we provide some numerical examples on the proper model choice for atmospheric dispersion studies, depending on their main purpose.
