摘　　要：建立了秦山二期核电厂ICARE2程序堆芯计算模型,分析了小破口失水加全厂断电事故的堆芯熔化进程。计算结果表明,堆芯在3 923 s开始破坏,在4 284 s时发生移位并逐渐形成熔渣,4 951 s时堆芯内的一个流道完全堵塞,计算结束时,约产生了66 000 kg固态熔渣和9 000 kg液态熔渣。The calculation model of Qinshan phaselINPP has been built and the analysis of SBLOCA plus station blackout for core meltdown has been performed by using ICARE2 code. The calculation results show that the core starts damage from 3 923 s, starts dislocation from 4 284 s and the channel is completely blocked at 4 951 s. There are about 66 000 kg solid debris and 9 000 kg liquid debris are produced at the end of the calculation.
