In denitration process of FBR fuel cycle, the mixed oxides (MOX) fuel powder is reproduced from spent fuel with microwave heating direct denitration method. Although this method is possible to produce high quality pellet fuel, flushing phenomenon from a vessel sometimes occurs. So it is necessary to prevent the occurrence of the flushing for safety production of MOX powder. Consequently, the objective of the present study is to investigate the mechanism of flushing. For detailed observation of boiling behavior, the experimental apparatus which radiates microwave and high speed video camera were used. In order to reveal the influence of particles as bubble nucleus to the flushing, water with nylon particles and water without nylon particles were compared. As a result, it became clear that the particles affect the appearance of flushing.
