[1A17] Assessment of dust dispersion data for future safety analysis of Fukushima Daiichi fuel debris retrieval
(15) Simulations to evaluate the effects of casing shape and cutting conditions on the dust dispersion behavior
Keywords:dust, dispersion behaivor, particle tracking method
We have developed a simulation method for the dust dispersion behavior on the basis of the particle tracking method, and confirmed that simulation results are in good agreement with experimental ones. The dispersion ratio of the dust from debris in Fukushima site depends on various parameters, e. g., measurement positions or cutting conditions. In this study, we calculated the dispersion ratio in the large and small casings and under the different cutting conditions to discuss effects of such parameters.
