Abstract
The article presents the results of a simulation of the TOSQAN (France) and CSE (USA) experiments on the capture of aerosol fission product simulators by droplets of the spray system using the MAVR-TA code. The calculation results are well-correlated with experimental data. The main mechanisms for capturing aerosol particles by sprayed droplets under conditions of beyond-design-basis accidents are described. Analytical calculations were carried out to study the effect of aerosol particle density on the efficiency of particle removal. According to the performed calculations, the density of aerosol particles has a significant impact on their removal from the atmosphere of the containment.
