Keywords:PIV measurement , gas entrainment, Sodium-cooled Fast Reactor

The PIV measurement was performed for unsteady hollow vortexes which move on liquid free surface and lead to gas entrainment. It was found that the gas entrainment occurrence condition and the flow velocity profile around the hollow vortexes leading to the gas entrainment.
