The purpose of this study is to grasp the efficiency of thermal control regarding steel plate by using water discharge system. The experiments were carried out by using the radiation panel at BRI. The specimen, that is steel plate in this paper, is one size (Height: 1000[mm]; Width: 500[mm]; Thickness: 5[mm]). The experimental conditions have changed the water supply rate gushed from water discharge equipment and the heat flux rate from radiation panel to steel plate and so on. As the results of experiments, the following tendencies were acquired; the character of water film relates to Reynolds number, the temperature rise of specimen (steel and water) is clearly decreased by effect of water film and the efficiency of thermal control becomes higher so that the water supply rate increases.
