According to internal investigations of Fukushima Daiichi NPP Unit-2 and 3, shield plugs has been reported to be highly contaminated by a large amount of cesium. However, the mechanism is not well understood, and the cesium behavior cannot be reproduced by SAMPSON analysis so far. In the present study, the contamination mechanism will be investigated based on SAMPSON analysis with aerosol resuspension model.
