In terms of improving the safety of LWRs, it is important to reproduce and evaluate the behavior of the melting core as a liquid jet when it falls into a shallow pool during the severe accident. JAEA has developed numerical simulation codes that can reproduce the behavior and has conducted experiments by using the 3D-LIF method for the validation. As a part of the experiment, we have investigated the effect of the liquid film structure on fragmentation amount based on the observation result of the changes of fragments amount and the structure. In this work, we estimated fragmentation time of the individual fragments by using the experimental data, calculated volume of fragments at the time and estimated fragmentation amount.
