To contribute to the decommissioning of Fukushima Daiichi Nuclear Power Station, analysis of the fuel debris obtained from the trial retrieval at Unit 2 is underway to characterize their properties. This series of presentations will report key findings from various analyses, including non-destructive analysis, solid analysis, and solution analysis. Initially, this presentation will outline the analytical plan; specifically, the elements and phases targeted for analysis will be detailed based on insights gained from previous analyses of U-bearing particles.
