摘要
反应堆安全注射系统是包含复杂操作时序的动态系统,本文研究了应用GO-FLOW方法对其进行可靠性分析,导出了能将GO-FLOW用于含两种失效模式的可修部件状态概率计算的可靠性参数等效模型,并验证了模型的正确性。给出了实际算例,结果表明,GO-FLOW方法是对含时序问题的动态系统进行可靠性分析的有效工具,本文导出的可靠性参数等效模型提高了GO-FLOW对多状态问题的分析能力。
The safety injection system in nuclear reactor can be regarded as a dynamic system which contains complex operation sequences. The application of GO-FLOW methodology was studied to the reliability analysis on the safety injection system in this paper. A equivalent calculating model of reliability parameter, which can be used to calculate the state probability of the repairable component containing two-failure style, was put forwarded, and the validation of the calculating model was also discussed. A practical calculating example was presented, and it shows that the GO-FLOW is an effective tool in reliability analysis of dynamic system containing complex time sequence problem, and its ability in dealing with the multi-state problem is improved by the equivalent calculating model of reliability parameter.
