Study of Jet Behavior Under SGTR Accident Conditions With Simulant Experiment
Steam Generator Tube Rupture(SGTR)accident is one of the severe events in the Lead-cooled Fast Reactor(LFR).Under SGTR accident conditions,the secondary loop coolant water comes into direct contact with the high temperature molten Lead-Bismuth Eutectic alloy(LBE)in the primary loop,resulting in a vigorous interaction.To further investigate the injection behavior of water jets in molten LBE,an experimental platform for visualizing the two-phase flow of liquid jets was designed and constructed in this study,and a series of simulant experiments were carried out.In this study,the evolution of jet flow patterns in boiling(including flashing jets)and non-boiling conditions was first investigated.The effect of injection rate on the maximum injection depth was also quantitatively analyzed.At last,based on the experimental data,the Froude number theory was applied to analyze the injection velocity and the maximum injection depth under non-boiling conditions,and a dimensionless semi-empirical relationship was obtained.
