摘　　要：针对大型民用核动力船舶的安全性问题,应用层次分析方法对民用船舶核动力装置的二回路系统进行故障分析,以此为其运行安全性提供理论依据和技术支撑。通过建立一个基于研究目标的多层次递阶结构模型对民用核动力船舶二回路系统进行故障分析及风险评估,确定对二回路系统影响最大的指标参数。研究结果表明:二回路系统中汽动给水泵系统、电动给水泵系统、主给水流量控制系统和高压给水加热器系统为风险较大的关键因素。Considering the safety issues of the civil nuclear-powered ship operation,the analytic hierarchy process（ AHP） was used for fault analysis of the second loop system of the civil marine nuclear power plant,which provided a theoretical basis and technical support for the safety operation of civil nuclear powered ships. The greatest impact indicator parameters on the system failure were found through fault analysis and risk assessment for the structural model of the second loop system that was established using AHP. The result showed that the steam feed water pump system,motor-driven feed water pump system,main control system of feed-water flow,and high-pressure feed-water heater system are the key risk factors in the second loop system.
