This paper presents the results of visibilitization experiment which is carried out to measure the pressure rise and to observe the wave propagations when the explosion occurs in the model of nuclear fuel cycle facility (NFCF). Numerical simulation is also performed to compare the phenomena in NFCF. NFCF is modeled as the closed space in these experiment and simulations. As a result, it is confirmed that the explosion which occurs in closed space is reflected in the complexity at the walls and interfered mutually with progressing waves. It is observed that the pressure rise repeatedly at the corner in the rooms.
