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.
High-level waste consists mainly of spent fuel rods from nuclear reactors. These power plants rely on nuclear fission to generate heat, and the fuel is made into rods that can be moved in and out of the reactor core to control the process.isposal. High-level waste is generally stored on site at nuclear power plants until a proper disposal site becomes available. During this initial storage period it is kept under at least 20 feet (6 meters) of water, which absorbs the radiation.
