Description

technical field [0001] The invention belongs to the technical field of nuclear power control, and in particular relates to a control rod driving system based on vibration detection of a coolant pump. Background technique [0002] The control rod is made of materials that are easy to absorb neutrons such as boron and cadmium. There is a mechanical device outside the nuclear reaction pressure vessel to manipulate the control rod. When the control rod is fully inserted into the reaction center, it can absorb a large number of neutrons to prevent the fission chain. During the reaction, if the control rod is pulled out a little, the reactor starts to run, and the speed of the chain reaction reaches a certain stable value; if you want to increase the energy released by the reactor, you only need to pull out the control rod a little more, so that the absorbed medium Fewer neutrons, and more neutrons are involved in the fission reaction. [0003] In the prior art, the systems discl...
