The most severe postulated events (called bounding case) should be considered for effective evaluation of system design in nuclear power plants. In this article the most severe case for evaluation of core catcher design is discussed. Among the most important boundaries for mitigation of severe accident effects, core catcher is the last one. Severe accidents are divided into two categories: Low Pressure (LP) and High Pressure (HP). From the core catcher point of view, HP accidents are more severe because the corium is evacuated to the core catcher at a higher pressure, and the possibility of failure is increased. Among the HP severe accidents, the most severe cases belong to the Station Black Out (SBO) and Loss of Offsite Power (LOOP). After Fukushima Daiichi accident, most of the publis... view more»
