Use of post test analysis for the characterization of aerosol in the storm (simplified tests on resuspension mechanisms) project.
The STORM (Simplified Tests on Resuspension Mechanisms) Project was deisgned to study aerosol transport phenomena in reactor components during severe accidents, allowing representative experiments under prototypical conditions to be performed. In these particular experiments, aerosol deposition and resuspension in a 5m-long stainless steel tube were studied. The two aerosols selected for the experiments were the insoluble SnO2 and a mixture of SnO2 with the hygroscopic CsOH. The first part of the programme, with only solid aerosols (SnO2) was complted with success, but post-test analysis was required before proceeding to the second part, with the use of SnO2/CsOH mixtures. The analysis of material from the experiments involved the use of an highly sensitive energy-dispersive x-ray fluorescence (EDXRF) spectrometer, as well as a light microscope with magnification lenses of up to x1500. As was expected, the particle size decreased from stage to stage of the eight-stage series of impactors and filters in the tube.
