Sodium Aerosol Studies for Fast Reactor Safety

Generation and characterization of sodium aerosols contribute significantly towards safety studies of fast reactors and it is useful to assess the environmental source term. The characterization include both chemical and physical characteristics of sodium aerosols that are generated in the case of release of hot sodium into the atmosphere and causing sodium fire which causes dense sodium fumes. In IGCAR, an aerosol test facility, having 1 m3 volume with controlled humidity for carrying out physical and chemical characteristics of sodium aerosols, is in operation. In this paper the suspended mass concentration of sodium aerosols inside the closed environment (inside the aerosol chamber) and its theoretical predictions are presented. The experimental results are used for the theoretical determination of suspended mass concentration of sodium aerosols inside RCB in the case of CDA, using HAARM code and these results are also presented.
