WebAug 25, 2024 · Control Rods. Nuclear reactors use control rods (Figure 25.8. 8) to control the fission rate of the nuclear fuel by adjusting the number of slow neutrons present to keep the rate of the chain reaction at a safe level. Control rods are made of boron, cadmium, hafnium, or other elements that are able to absorb neutrons. WebThe delayed-neutron emitters among the fission products increase the time between successive neutron generations in the chain reaction and make the control of the reaction easier to accomplish by the mechanical movement of the control rods. Fission reactors can be classified by the energy of the neutrons that propagate the chain reaction.
