摘　　要：为实现海上核动力装置的三维热工水力特性模拟,对运行培训、事故诊断、安全分析等提供技术支持,本研究基于PANTHER程序,开发了一维/三维运动附加力模型、三维运动坐标计算模型、三维非惯性坐标系运动计算模型、输入/输出(IO)集成交互模块,并集成于RINSIM仿真平台,实现了参数实时交互及运动条件在线切换,并基于两环路单相自然循环试验装置完成了对比测试验证。验证结果表明,各海洋运动条件下计算结果满足物理规律,与实验值计算误差在5%以下,证明了程序计算结果的可靠性。本研究开发的海洋条件三维热工水力系统分析程序能够用于海上核动力装置的三维热工水力特性仿真。To realize the simulation for three-dimensional thermal hydraulic characteristics of offshore nuclear power plants and provide technical support for operation training,accident diagnosis and safety analysis,this study,based on the PANTHER code,has developed the 1D/3D additional force model,the 3D motion coordinate calculation model,the 3D non-inertial coordinate system motion calculation model and the IO integrated interaction module,which are integrated into the RINSIM simulation platform.Real-time interaction of parameters and on-line switching of motion conditions are realized,and the comparative test verification is completed based on the two-loop single-phase natural circulation test device.The verification results show that the calculation results of each motion condition meet the physical laws,and the calculation error with the experimental value is below 5%,which proves the reliability of the code calculation results under the condition of marine motion.Therefore,the 3D thermal-hydraulic system analysis code developed in this study can be used to simulate the 3D thermal-hydraulic characteristics of offshore nuclear power plants.
