“…Thermal-hydraulic analysis of loss-of-coolant, emergency-core cooling and severe-core damage designed by Japanese Atomic Energy Research Institute, aims to predict the progression of the core in severe accident conditions of LWRs (Abe et al, 1986;Abe, 1990;Hashimoto and Soda, 1991;Ishikawa et al, 2002).
