Keywords:1F decommissioning, model debris, microstructure, mechanical property

In order to understand the property change and cracking behavior of 1F fuel debris occurred probably during the accident, clod shutdown period, and fuel debris retrieval period, the metallic debris which is composed of the reactor core component materials of zirconium (Zr), stainless steel (SUS), B4C was studied in this study. In this report, the model debris with different Zr/SUS ratios was prepared by high-frequency induction heating, followed by the microstructural characterization and mechanical property evaluation. The research progress about the acquisition of fundamental properties of each constituent phase such as hardness and Young’s modulus will be presented.
