In this study aiming at contribution for safe decommissioning of Fukushima-Daiichi NPP, CFD (Computational Fluid Dynamics) method was applied and temperature distribution of Unit 3 was reproduced. This temperature distribution was then compared with the measured data obtained by TEPCO so that debris distribution can be estimated. Combined application of optimized tools and CFD method to resolve inverse problem determining best suited thermal balance within the containment vessel is a characteristic of this study.
