Abstract
Prediction of the behavior of radioactive aerosol particles in a containment is of importance for the assessment of
the consequences of nuclear power plant severe accidents because most radioactive air pollutants are emitted as aerosol
particles upon severe accident. The performance of engineering safety features (ESFs) is also influenced by the
characteristics of the aerosol particles. In this article, the characteristics of aerosol particles in reactor containments
reported by previous studies were reviewed. The results of the experiments for postulated accidents in test reactors, for
aerosol behavior analysis using artificial test aerosols, and for ESF performance evaluation were summarized. The
summary of this article will be of use in designing and performance-evaluating ESFs.
