Forced vibration tests were conducted for determining the mechanism of vibrational phenomena regarding the overflow of water during an earthquake by means of applying a visualization method to a scaled two-dimensional sliced model of a spent fuel storage pool containing submerged blocks. Findings clarified through the tests are as follows: (1) The forced vibration is conducted with the blocks placed in a row in submerged position. the damping factors of the sloshing modes show obvious increase, and consequently submerged blocks are effective in reducing the wave height comparing to the case without blocks. (2) Submerged blocks reduce sloshing very effectively. while they share large forces produced by sloshing phenomenon. (3) The installation of water restraint plates at both end walls is found to be very effective in reducing sloshing.
