Keywords:gas entrainment, CFD analysis, fast reactor

CFD analysis has been performed for unsteady hollow vortexes which move on liquid free surface and lead to gas entrainment. The gas entrainment conditions were compared with experimental results. As a result, it was found that the evaluation method for the gas entrainment from the moving vortexes indicates rather conservative results.
