Kawakami, Taira*; Sakurada, Keishi*; Sakashita, Hiroto*; Ono, Ayako ; Yoshida, Hiroyuki

The effect of height and density of accumulated particles on the critical heat flux was investigated on the heating surface, where the particles were accumulated, in order to investigate the cooling process of debris under the severe accident. The thermal-hydraulic behavior on the heating surface was visualized from the backsides of heating surface made of glass.
