[1F12] Study for Evaluation of Spreading Behavior of Molten Core Free Fall under Dry Condition

*Yuta Watanabe1, Yasunori Yamamoto1, Tomomasa Ito1 (1. Hokkaido University Graduate School of Engineering)

Keywords:Moltern core, Moltern metal, Free fall, Spreading behavior

In order to accurately predict the progress of debris cooling and MCCI during core melting, the impact of falling

It is necessary to properly evaluate the spreading behavior of debris in consideration. In this study, the

The purpose is to acquire basic data necessary to evaluate the spread behavior of

The experiment was conducted using a simulated substance. As the mimic substance, water, glycerin and metal which can ignore the influence of coagulation were used.
