Significant level of fuel debris was generated by the core meltdown in the Fukushima Daiichi nuclear disaster. In order to conduct defueling operations, understanding the properties of the fuel debris is of extreme importance. Fe2B is one of the various compounds in the fuel debris, which is considered to be formed through the reaction between the control rod material B4C and stainless steel. However, the previous reports for bulk Fe2B have been limited, which gave us the necessity of the additional study for that. In the present study, we have prepared a Fe2B bulk sample with 92.5 % theoretical density by sintering Fe2B powder. From this sample, we have comprehensively examined the thermal and mechanical properties of Fe2B by the measurement of thermal diffusivity, Vickers hardness and etc. Vickers hardness and fracture toughness were obtained to be 14.9 GPa and 3.11 MPa m0.5 in maximum, respectively.
