During a Fukushima Daiichi Nuclear Power Plant accident, volatile fission products (FPs) such as caesimu (Cs) and iodine (I) had been released from the nuclear fuels and caused environmental contamination and public exposure. However, the release mechanism has not been completely understood. In recent years, we are investigating the melted caesium iodine (CsI) behaviour on the nuclear fuel solid surface by using the sessile drop method, which is widely used for the measurement of surface energy, because the fuels solid surface could be the migration pathway when Cs and I are released. Here,we report the new findings about the melted caesium compounds behaviour on the ceramics solid surfaces including the uranium dioxide (UO2) and thorium dioxide (ThO2). The details of the experimental procedure and the results will be presented.
