In order to verify the solidification path diagram [1] (Figure 1) created based on the data of debris samples collected at Tokyo Electric Power Company Holdings, Inc.'s Fukushima Daiichi Nuclear Power Plant (hereinafter referred to as 1F), We synthesized a simulated debris material using mixed powder pellet tets and reaction tests between UO2 pellets and metal samples.
