Analysis of mitigation capability of high-pressure safety injection system to SBO accident for PWR
Description
Taking a typical three-loop PWR as the reference plant and using the best estimate computer code RELAP/SCDAPSIM /MOD3.2, a representative three loops PWR severe accident calculation model is established and station blackout (SBO) induced core melt progression is analyzed. The mitigation capability of high-pressure safety injection system to severe accident is studied. The sensitivity calculation results show that the severe accident management strategy of bleed-and-feed cooling when the core outlet temperature reaches to 920 K can prevent the core damage effectively and the reactor core can achieve a long term safe stable state.
