The uranium fission is most common in nuclear power generation, namely uranium-235 is used as nuclear fuel, 2-3 free neutrons are emitted after thermal neutrons bombard uranium-235 atomic nuclei, and the fission reaction can be continuously carried out after the neutrons strike other uranium-235 atomic nuclei, namely the chain type nuclear fission reaction. Scientists have developed methods for controlling the rate of fission reactions in the nuclear chain by absorbing neutrons based on their principles: the control rod is made of materials which can easily absorb neutrons such as boron, cadmium and the like, and the fuel consumption is compensated and the reaction rate is adjusted by adjusting the depth of the control rod inserted into the nuclear fuel, so that the reaction is kept stable, or the reaction is stopped when necessary: if the energy needs to be increased, only a proper amount of control rods need to be drawn out, namely the insertion depth is reduced, so that the absorbed neutrons are reduced, and more neutrons participate in the fission reaction; if the chain type nuclear fission reaction needs to be stopped, the control rod is only required to be completely inserted into the nuclear fission reaction center to absorb most neutrons.
