摘　　要：利用200MW低温核供热堆水力控制棒驱动系统的1∶1实验台架模拟系统失压工况,进行控制棒步升、步降、开阀落棒及关泵开阀落棒实验,并与正常工况下的提棒、落棒的实验结果进行比较。实验结果表明:在系统失压工况下,控制棒能正常提棒、落棒;模拟系统失压工况下的弹棒,系统压力与压力壳压力具有瞬时跟随特性,未出现控制棒弹棒事故。对实验的失压速率和事故分析得到的失压速率进行了比较,验证了系统具有良好的安全性和可靠性。Through simulating depressurization condition, the experiments are carried out by the 1:1 experiment loop of hydraulic control rod driving system for 200 MW nuclear heating reactor. The experimental results of step-up, step-down and scram in normal condition and depressurization condition indicate that control rod can step-up, step-down and scram normally in depressurization condition. The rod ejection experiment in depressurization condition also is carried out. The result indicates that the system pressure will follow the pressure of the pressure vessel instantaneously and the control rod can't engender rod ejection accident. The hydraulic control rod driving system has inherent safety and reliability.
