| 摘 要： | 钠火事故是钠冷快堆的典型和特有事故，且很可能是反应堆总风险的主要贡献因素之一。本文在介绍钠火事故特点的基础上，研究使用概率安全分析评价钠冷快堆钠火风险的方法。以中国实验快堆反应堆大厅钠火事故为实例，计算得到反应堆大厅钠火导致的堆芯损坏频率为1.19×10-8/(堆?年)。在此基础上进一步讨论目前钠火概率安全评价中尚需研究的关键问题。

| Abstract: | The sodium fire is a typical and distinctive hazard in sodium cooled fast reactor, which is probably one of the main contributors to the total reactor risks. In this paper, the methodology of fast reactor sodium fire risk assessment was studied, following the introduction of the sodium fire. The application of this technology in China Experimental Fast Reactor was explored, and the results show that the core damage frequency induced by the sodium fire in reactor hall is 1.19×10-8/(reactor?year). After that, several key problems which need to be further researched in the future during the process of sodium fire probabilistic safety assessment were discussed. |
