For the retrieval of the PCV fuel debris, it has been required to obtain comprehensive fuel debris characteristics. In this study, the effects of the difference of accident scenarios on the characteristics of fuel debris are reported by carrying out both the corium simulant spreading experiment and the arc-melting experiments.
