The integrity of concrete structures in nuclear power plants has risen as a major issue in recent years. This is due to the needs to assess the safety of structures after the accident at the Fukushima Daiichi Nuclear Power Station for decommissioning process. In order to be able to assess the current state of concrete structures, understanding degradation mechanism and developing appropriate test methods for on-site application are required. For that reason, this study primarily focuses on the effect of high temperatures aimed to enhance the knowledge of degradation mechanism due to thermal exposure.
