摘　　要：基于对核动力装置稳压器安全阀系统功能及任务剖面的分析,建立了基本可靠性框图和任务可靠性框图,并采用普通概率法得到了相应的可靠性数学模型。该可靠性模型为下一步进行故障模式、影响及危害性分析(FMECA)和可靠性分配提供依据。Based on the analysis of the function and mission profile of the pressurizer safety valve in nuclear power facilities, the basic reliability diagrams and the mission reliability diagrams were developed, and the reliability mathematical models were derived with the universal probabilistic method. The reliability modeling work is essential to the failure modes, effect and criticality analysis （FMECA） and reliability allocation.
