ＡＣ６００二次侧非能动应急堆芯余热排出系统实验装置是一座大型非能动安全系统实验研究装置。在设计上，它以热工水力模拟理论及模拟准则为依据，在保持原型系统主要热工水力现象和过程的前提下，对系统进行了必要的简化。本文介绍了该实验装置回路、电气、仪表及测控系统的设计原则和设计结果，以及第一阶段研究计划和内容。最后，根据调试和运行结果总结了设计特点和经验 AC600 secondary passive residual core reactor exhaust heat rejection system experimental device is a large non-active safety system experimental research device. In the design, based on the thermal hydraulic simulation theory and the simulation criterion, the system is simplified as necessary while keeping the main thermal hydraulic phenomena and processes of the prototype system. This article introduces the design principles and design results of the loop, the electrical, instrumentation and measurement and control system of the experimental device, as well as the first phase of the research plan and content. Finally, the design features and experience are summarized based on the results of commissioning and operation
