摘要: 将THERMIX/BLAST程序嵌入至vPower仿真平台,开发球床模块式高温气冷堆示范电厂(HTR-PM)工程模拟机。在该工程模拟机上进行双堆冷启动过程和双堆正常冷停堆过程的模拟仿真,分析2种工况中反应堆功率、氦气流量、蒸汽发生器出入口参数及汽轮机入口蒸汽参数等关键参数的变化趋势,总结双堆冷启动过程和双堆正常冷停堆过程的运行特点。结果表明,2个反应堆在运行过程中互相影响,二回路参数变化是2个反应堆耦合的结果。

Abstract: An engineering simulator of HTR-PM is developed by embedding THERMIX code into the vPower simulation platform.The double reactor cold start-up and shutdown processes are simulated on the engineering simulator,to analyze the changing of the critical data such as the reactor power,helium mass flow,inlet/outlet parameters of steam generator and inlet vapor parameters of turbine in these two conditions.The operation features of the double reactor cold start-up and shutdown processes are summarized.The results show that the two reactors influence each other during the operation and the parameter changes in the secondary loop are the combined results from two reactors.
