中文摘要: |
物理过程失效的研究对于非能动系统来说是十分重要的,目前重要抽样的蒙卡方法应用最广.但是该方法寻找设计点时要依赖于一次二阶矩法,还要对参数标准正态化,本文提出的基于自适应原理的蒙卡方法,可以避免上述不足.以245 MW海水淡化堆非能动系统为研究对象,同时应用自适应蒙卡方法和目前其它方法研究其非能动系统的物理失效概率,最后分析各方法在非能动系统上的适用性,研究表明基于自适应原理的蒙卡方法计算结果更佳,该方法不仅寻找设计点较简便,而且对抽样效率、计算误差等方面都有较好改善. |
英文摘要: |
Adaptive monte carlo method can avoid the short comings of first-order and second-moment methods when searching for design point,such as the standardization of the parameters.This paper takes the passive system of nuclear desalination reactor for example,calculating the physical process failure probability of it using four methods,and then make acomparation.Finally,through analyzing the sensitivity of all the critical parameters related to the passive systems,we found that the uncertainty of trip water level,reactor power and the pipe resistance coefficient are most important to the reliability of the passive systems. |
