Inverse problems in nuclear engineering; Old but new approach for bottleneck removal

Itagaki, Masafumi*; Kurihara, Kenichi

Nihon Genshiryoku Gakkai-Shi, 44(12), p.873 - 878, 2002/12

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.

The Simulation of temperature distribution in 1F Unit 3 by using CFD method

Kaku, Eiji*; Okamoto, Koji*; Kondo, Masahiro*; Ozdemir, E.*; Shiba, Tomoki*; Sato, Ikken

no journal, , 

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.
