Abstract

The safety analysis on LOVA is among the last task left in ITER R & D. On the assumption of LOVA after ICE, it is corollary that activated dusts are under wet condition. The transport behavior of dust under the wet condition is not known well in comparison with dry case even in the conventional engineering systems. Moreover, in the case of LOVA after ICE a shock wave is assumed to generate in the vacuum vessel. The purpose of this experimental study is to investigate the dust behavior under the wet condition including the interaction between shock wave and dust by supposition of LOVA. In this experiment, entrainment ratio and adhesion ratio of dust are measured and discussed. Thereby we understood the behavior of dust in the wet condition and report it.
