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.
Nuclear fuel is made of solid pellets that contain enriched uranium. These small, ceramic-like pellets create a tremendous amount of energy when used in a nuclear power plant. For example, one pellet has an amount of energy equivalent to almost one ton of coal.The pellets are sealed in tubes of a strong corrosion-and heat-resistant metal alloy.o understand how nuclear fuel generates electricity, think about how other power plants work. When electricity is generated at coal-fired plants, coal is burned to produce heat to make steam. At nuclear power plants, fission within the fuel pellets creates the heat used to make steam to turn turbines.
