摘　　要：在非能动安全功能可靠性方法(RMPS)框架下,对某型核动力装置非能动余热排出系统原理性试验系统的热工水力可靠性(TH-R)进行评估,并对影响系统可靠性的不确定性参数进行敏感性分析。相关结论有助于从可靠性角度增强对该非能动余热排出系统热工水力过程不确定性的认识,可用于指导系统的设计优化及运行管理。Under the framework of RMPS （Reliability Methods for Passive Safety Functions）, thermal-hydraulic reliability （TH-R） of an experimental facility is evaluated, and sensitivity analysis is applied for uncertainty parameters which has effects on the TH-R of the passive systems. Related conclusions contribute to understand the uncertainty of the thermal hydraulic processes of the passive residual system from the view of reliability. Results of reliability and sensitivity analysis can be used to guide the system optimal design and operation management.
