摘　　要：针对核反应堆系统热工分析软件RELAP5存在的人机交互不友好的问题,本文开发了可视化交互式核动力系统模拟平台VITARS。VITARS在可视化用户操作界面的基础上,满足RELAP5模块化建模、计算运行控制、计算结果实时显示和多RELAP5耦合计算的功能需求,还具备一个反应堆控制逻辑计算系统。通过VITARS用户可在计算过程中对阀门开度、主泵转速等参数进行手动调节。另外,得益于普适性的数据交互接口,VITARS还可作为一个交互平台,具有与其他热工水力程序耦合的可行性。最后通过对岭澳核电站机组的稳态模拟验证了VITARS的计算准确性。RELAP5 is one of the most commonly used programs for reactor thermal hydraulic analysis. Due to the early developing time, RELAP5 does not have a friendly graphical user interface and interactive interface, resulting in the lack of human-computer interaction ability. In this work, the visual interactive simulation platform VITARS was developed by Java Script language based on Node.js framework. The origin RELAP5 was reformed then integrated into VITARS, and a bidirectional data communication pipe was established between RELAP5 process and VITARS process. In VITARS, a modeling module was developed, in which all the components in RELAP5 were abstracted into different pictograms and users could complete graphical modular modeling and parameter input for RELAP5 conveniently by stitching these pictograms, thus the use threshold of RELAP5 could be reduced. Due to the data communication pipe, VITARS could send control instructions to RELAP5 for pause, run, snapshot, terminate etc. The calculation results in RELAP5 could be displayed in VITARS as dynamic data meter or dynamic time-data curve in real time, and could be saved in VITARS for future viewing and extraction. In addition, a new signal logic computation system was developed in VITARS, in which more than forty kinds of signal logic computing components were built-in such as logical gate, proportional-integral, time delay integration, and flip-flop. As a data processing center for VITARS, the new signal logic computation system could read the thermal-hydraulic calculation results from RELAP5, user’s operation instruction etc., these data could be processed then distributed to RELAP5 to replace the thermal hydraulic boundary in time dependent component, adjustable equipment parameters or origin control data in the next time step, and could also be distributed to the data display system for real-time display. Therefore, with VITARS, complex proportion integration differentiation control system could be built for RELAP5, and user could adjust valve opening, pump spe
