Common Cause Failures Analysis of PWR Purification System Based on GO Methodology

College of Naval Architecture and Power, Naval University of Engineering, Wuhan, 430033, China

摘要: 应用GO法分析了共因失效对压水堆净化系统可靠性的影响。采用GO法的运算法则,求出净化系统状态概率表达式,并根据GO法的共因失效的算法计算出共因失效对系统不可用度的贡献。结果表明,共因失效对压水堆净化系统可靠性有很大影响。

Abstract: GO methodology was applied to analyze the reliability of PWR purification system with common cause failures.The expression of purification system state probability was derived under the algo-rithm of GO methodology and the contribution to system unavailability caused by common cause failures was calculated in the way GO methodology dealing with it.The results show that the common cause failures greatly affect the reliability of PWR purification system.
