Abstract
The calculational model of ICARE2 V2mode2.3 has been built for Qinshan Nuclear Power Plant and the simulation of early core degradation of SBLOCA with station blackout has been performed. The calculation results show that the core starts damage from 4 560s and the whole process of early core degradation is relatively fast due to poor core cooling conditions. The analysis of early core degradation is only valid up to around 7 900s.
