摘　　要：安全壳是核电厂实现放射性物质包容的最后一道屏障,安全壳条件失效概率是评价核电厂从堆芯熔化到安全壳失效整个阶段缓解系统的重要指标。本文探讨了安全壳条件失效概率的起源,对安全壳条件失效概率指标进行了解读,介绍了国内各先进压水堆核电堆型的安全壳条件失效概率的现状和主要贡献项并给出了相应的结论和建议。The containment is the last barrier to achieve radioactive products contained for nuclear power plants. Conditional containment failure probability（CCFP） is an important index for evaluating the performance of containment. The history of CCFP,the meaning of CCFP are discussed in this paper,and the current situation of the CCFP for some advanced PWR nuclear power plants in China is introduced. Finally,some conclusions and recommendations are given.
