[3F06] Investigation on thermal deterioration of concreate in severe accident
Keywords:Concreate, Magnesia-Carbon brick, High temperature, Thermal deterioration, Void ratio
Development of small type of core catcher is needed. In this investigation, the thermal deterioration of concreate and Magnesia-Carbon brick was evaluated by the measurements of compressive strength, weight, and void ratio. As a result, both of concreate and Magnesia-Carbon brick lost its weight, volume, and strength mostly relate with heating temperature.
