The fire and explosion accident happened at the bituminization demonstration facility of Power Reactor and Nuclear Fuel Development Corporation (PNC) of Japan on March 11, 1997. To elucidate smoke generation and clogging mechanism of ventilation filters under burning of bitumen/salt mixture in the PNC facility, small-scale simulation experiments were performed. The mock mixtures were prepared by referring to the composition of the real liquid waste and were burnt by heating. The burning behavior of the mixture was observed and the filter pressure drop, which was caused by loading smoke, was measured. Moreover, mass energy and smoke release rate as direct source term from the burnt mixture and the empirical equation, which could represent the relationship between the pressure drop and burnt mass, were determined by comparing between the calculation results based on a one-dimensional thermofluid analysis code CELVA-1D, and the experimental results.
