Through a review of experimental works on steam explosions and consideration on the uncertainty in the methodology for plant scale analysis of each stage of the phenomena, it was identified that the molten jet breakup process in premixing has an important uncertainty caused by lack of experimental knowledge. Based on this perspective, an experimental work are under planning at Japan Atomic Energy Research Institute (JAERI), in which the premixing stage of steam explosions in a deep water pool is modeled by high temperature oxide melts. The melt material and the scale of the experiment was discussed in terms of the simulation capability of the jet breakup mechanism in a plant scale phenomena. Materials and geometrical scale which are considered adequate were found.
