In order to take out fuel debris, it is necessary to grasp thermal properties and mechanical characteristics of debris. In this study, a eutectic composition of Al 2 O 3 / ZrO 2 containing voids is prepared from among compounds which may be generated by reaction of fuel debris and concrete, and the porosity is determined by the thermal properties of the eutectic composition and the mechanical properties Evaluate how it affects the characteristic.
