An inverse problem has been known as a method to identify the cause on the basis of consequent observation and mathematical investigation. In recent years, the advancement of computer technology and numerical algorithms has stimulated this field of methodology. This leads to that an inverse problem is being noted as a new area of apllied physics and engineering. In this review, several inverse problems dealt in the nuclear engineering are presented together with the updated topics on this problem.

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.

【課題】地上の起伏とか樹木の有無のような測定場所の状況に影響されず、地上付近の空間線量を高精度に測定できる方法及びそのための装置を提供すること。 【解決手段】測定ポイントデータと、計算ポイントデータを取得し、上空からの放射線測定用に導き出した、空気による減衰、土壌散乱による減衰、森林による減衰のパラメータを考慮して、それぞれの測定ポイントと計算ポイント毎に検出確率を計算し、算出した検出確率値を用いてML-EM法の手法に則り、繰り返し計算を実施して放射線強度値を求め、算出した放射線強度値を用いて、空間線量換算係数により空間線量率に換算する。
