Control Rods. The nuclear chain reaction may be controlled using a device called a control rod. Control rods are made of materials which absorb neutrons. Thus, when a control rod is inserted into a nuclear reactor it reduces the number of free neutrons available to cause the uranium atoms to fission.
The difference is that nuclear plants do not burn anything. Instead, they use uranium fuel, consisting of solid ceramic pellets, to produce electricity through a process called fission. Nuclear power plants obtain the heat needed to produce steam through a physical process. This process, called fission, entails the splitting of atoms of uranium in a nuclear reactor. The uranium fuel consists of small, hard ceramic pellets that are packaged into long, vertical tubes.
