本研究では福島第一原子力発電所の安全な廃炉に寄与すべく、数値流体力学(Computational Fluid Dynamics, CFD)を用いて3号機内部の温度分布を再現し、東京電力の測定結果と比較することでデブリの位置を推定する。最適化ツールとCFDを組み合わせることで格納容器内部の最適な熱バランスを求める逆問題を解いていることが本研究の特徴である。

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.
