Abstract:In view of the aerosol resuspension caused by denudation in the containment,the experimental research was carried out on the basis of comparison with the thermal-hydraulic hydrogen aerosol iodine aerosol resuspension (THAI AR1) test method,and the influence of different factors such as humidity conditions,airflow velocity,and deposition surface state were systematically studied.The results show that the verification test results are in good agreement with THAI AR1 and the test method is feasible.The aerosol resuspension rate caused by denudation is much lower than that caused by erosion,and there is an order of magnitude difference.

Keywords:resuspension；denudation；humid conditions；airflow velocity；state of sedimentary surface
