Description

Aerosol natural deposition model of gravitational sedimentation, diffusionphoresis, inertial impaction and thermophoresis are established based on integrated safety analysis model for 600 MW pressurized water reactor. Typical severe accidents are chosen, and natural deposition phenomenon of fission product aerosol is analyzed. Additionally, gravitational sedimentation model of MELCOR is coupled into integrated safety analysis model, and fraction of gravitational sedimentation is compared. The results show that gravitational sedimentation is the most important deposition mechanism, and deposition effect of gravitational sedimentation model in this paper is stronger than MELCOR.
