Abstract:  An Aerosol Test Facility (ATF) has been set-up at Radiological Safety Division (RSD), Indira Gandhi Center for Atomic Research (IGCAR), Kalpakkam, for the aerosol studies on fast reactor safety. In order to measure the Mass Median Diameter (MMD) of the aerosols in real time, a laser based instrument MASTERSIZER (M/s MALVERN, UK) is used. Mastersizer is provided with a liquid flow cell and a powder spray unit which are useful for the off-line measurement. For the real time measurement, an aerosol flow cell is designed and fabricated. It is integrated with the MASTERSIZER and the aerosol chamber of ATF. Aerosols are drawn through the aerosol flow cell whose optical windows are aligned with the laser path of MASTERSIZER. In this paper, the details and the performance test results of the aerosol flow cell are presented. Performance test of the aerosol flow cell is carried out with polystyrene latex particles of diameter 2.799 ┬Ám and methylene blue aerosols. Sodium oxide aerosols are generated and injected into the aerosol chamber, and the time evolution of MMD of sodium oxide aerosols has been studied.
