%X 核反应堆非能动系统参数敏感性分析是系统可靠性不确定性分析的重要组成部分。相关系数在刻画系统物理过程的成功准则参数敏感性方面存在缺陷，针对此问题提出迭代法，其综合了输入参数与成功准则的相关系数、偏相关系数以及输入参数之间的相关系数三方面信息，通过实例验证方法的正确性和实用性。迭代法适合分析参数对成功准则的偏相关性，能识别出更为精确的敏感参数，为进一步提高非能动系统物理过程的可靠性提供参考依据。</br>Parameter sensitivity analysis of nuclear reactor passive system is the main part of uncertainty analysis for passive system reliability. There are drawbacks for correlation coefficient to describe the parameter sensitivity of success criteria of passive system physical progress. So an iterative method was proposed, the method took account of correlation coefficient and partial correlation coefficient for input parameters, success criteria and correlation coefficient between parameters comprehensively, and the validity and practicability of the method were verified by a specific case. It is suitable for iterative method to analyze partial correlation of success criteria, to recognize more accurate sensitivity parameters and to provide reference for improving reliability of passive system physical process.
