Ishikawa, Nobuyuki; Chikazawa, Yoshitaka ; Morohoshi, Kyoichi*; Yamamoto, Hiroaki*

In the case of severe accident with core damaged events, the measurement of position and quantity of relocated damaged fuel is desirable to understand the progression of accident. In this report, the estimation method for measuring the position and quantity of damaged fuel based on the comparison between the results of the neutron flux analysis and neutron flux measurement is proposed.
