Gas entrainment (GE) at free surface is one of the significant issues for the design of Japan Sodium Cooled Fast Reactor. In the previous study, authors confirmed that GE did not occur under the conditions of the rated operating mode of the reactor. In the present study, water experiments were performed using the large-scaled partial model of the reactor upper plenum to simulate the startup operation of the reactor where the sodium level was lower than in the rated condition. The onset condition of GE was detected by the visualization of the free surface. Vertical velocity distributions were also measured in order to qualify the mechanism of GE. As a result, it was confirmed that GE did not occur in the startup condition of the reactor.
