In the characterization of the fuel debris generated by the accident at the Fukushima Daiichi Nuclear Power Plant (1F), analytical techniques corresponding to various chemical states are required in addition to the fact that the debris is usually a multi-component system. Therefore, we will construct a multi-scale analysis platform from millimeter to nanometer-scale by using advanced synchrotron radiation analysis technology and the latest electron microscope technology, and by linking these technologies with laboratory analysis like SEM. Furthermore, we will apply these techniques to the thermodynamic analysis of the U-Fe-O system and the development of new ceramic waste materials, which are being studied in this project, to confirm and evaluate their performance, and to further improve them in collaboration with the project. In this presentation, we will report on the plan and current progress of this research.
