| 摘 要： | 以压水堆严重事故最佳估算程序RELAP/SCDAPSIM/MOD3.4为核心软件，以假想的小型压水堆为研究对象，建立了1个径向3通道、轴向10节块的核反应堆严重事故计算模型，研究了完全丧失电源初因事件引发的严重事故过程，并对事故停堆后蒸汽发生器给水持续300s的缓解措施进行了分析。计算结果表明：蒸汽发生器辅助给水对于延迟事故进程，缓解事故后果具有重要作用。

| Abstract: | With the use of best estimate computer code RELAP/SCDAPSIM/MOD3.4 of pressure water reactor severe accident,a three-channel along radial and ten-nodal along axis nuclear reactor severe accident calculation model was established based on a hypothetical small PWR.The severe accident induced by total loss of power supply was studied,and mitigation measure with 300 s continuation of the steam generator auxiliary feedwater was analyzed.The calculation results show that the steam generator auxiliary feedwater plays an important part in delaying core melt progression and mitigating severe accident consequences. |

| Keywords: | small PWR severe accident total loss of power supply steam generator auxiliary feedwater |
