Abstract
For the safety design of a Fast Breeder Reactor (FBR), Post Accident Heat Removal (PAHR) is required when a hypothetical Core Disruptive Accident (CDA) occurs. In PAHR, it is necessary to understand the interaction between molten core material and coolant m order to estimate whether the molten material jet is completely solidified by the coolant. The objective of the present study is to clarify the dominant factors of the fragmentation behavior on the jet breakup. In this study, we inject molten material and transparent fluid into coolant at free fall speed. The jet breakup and fragmentation behavior of the molten material and the transparent liquid are observed with a high speed video camera. In addition, we simulate liquid jet using the lattice Boltzmann method m order to investigate the jet breakup and the fragmentation behavior, which are difficult to be visualized or measured in the experiment.
