核电机组二回路热力系统是核电站热经济性的集中体现，对核电机组二回路热力系统进行热力性能计算与分析是核电机组设计和运行中的重要课题。以某典型AP1000机组为例，基于Eclipse开发平台，运用Java语言开发出AP1000核电机组二回路主要设备及系统的离线性能计算与分析软件。通过该软件不仅能够快速直接地完成案例机组在设计工况和变工况下详细的热力计算分析，还可对机组主要热力参数变化时各项性能指标的变化进行快速计算；同时还可建立案例机组的性能档案列表与参数变化图。

The secondary loop of nuclear power plant can well represent the thermal economy performance.The thermal performance calculation and analysis of the secondary loop in nuclear power unit is an important issue in the design and operation of the nuclear power unit.With a typical AP1000 unit as the research object and based on Eclipse,this paper develops AP1000 off-line performance calculating software by using Java language.The software can not only complete the detailed thermal calculation analysis of the case unit under design conditions and variable working conditions quickly and directly,but also calculate the changes of various performance indexes when the main thermal parameters of the unit change quickly.At the same time,it is also possible to create a performance list and parameter change diagram of the case unit through the above calculation and analysis.
