Determination of Experimental Aerosols for Filtered Containment Venting System and Selection of Technical Parameter

In order to perform the aerosol removal efficiency tests of the containment filtered venting system, this paper focuses on the selection of the experimental aerosols for the research. Firstly, the characteristics of the aerosols in the containment are analyzed and the variation of the aerosol characteristics with time is calculated using several computational procedures. Then, on the basis of relevant research experiences of different countries and the special situation of this research, barium sulphate and titanium dioxide are finally selected as the experimental aerosols for this research with a mass median diameter of 1 micron, the system pressures of 1 to 6.5 bar, mass concentration of 50~900 mg/m³, geometric standard deviation of size distribution of 1~2.
