Outline of Final Research Achievements |
This study aims to establish analysis method to estimate released energy and radiation dose in the case of criticality accident of meltdown core. It was shown that it is possible to perform kinetic analysis when there are some fuel debris regions in different condition in the core by the use of newly developed code. A method was established to estimate the increase of released energy and radiation dose when fuel debris exists around the fuel debris which becomes critical.
