摘要
基于发生函数法对反应堆净化系统进行多状态可靠性分析,求取了净化系统的可靠性和其处于不同性能水平的概率,很好地反映了其系统的不同性能水平与系统可靠性之间的关系。同时考虑了共因退化和共因失效的影响。与传统的只考虑部件处于二元状态的系统可靠性分析相比较,该方法更贴合实际,具有很强的实用性。
The multi-state reliability of reactor purification system was analyzed based on the universal generating function（UGF）.The reliability of the purification system and the probability of the system at different performance levels were obtained.The results could well reflect the relationship between the system＇s performance and reliability.Meanwhile,the effect of common cause degradation and common cause failure（CCF） were taken into account.The results indicate that this approach is more practical compared to the traditional approach only considering the dual-state component.
