Description

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 not engender rod ejection accident. The hydraulic control rod driving system has inherent safety and reliability
