Abstract

By using a simulator based on SCDAP/RELAP5/MOD3.1 computer code, the core damage progression and theeffectiveness of preventive and mitigation measures are analyzed with the anticipated transients without scram （ATWS） sequences caused by the loss of main feed water （LOFW）, the loss of off-site power （LOOP） and uncontrolled rod cluster control assembly （RCCA） bank withdrawal, combined with the failure of reactor control and protection system in Qinshan Nuclear Power Plant （NPP） unit1.
