Uranium reactors are facilities that use uranium as fuel to generate energy through a process called nuclear fission. In this process, the nucleus of a uranium atom splits into smaller parts, releasing a significant amount of heat. This heat is used to produce steam, which drives turbines to generate electricity. These reactors are a key component of nuclear power plants, which provide a substantial portion of the world's electricity. Safety measures and containment structures are essential to prevent the release of radioactive materials, ensuring that the operation of uranium reactors is conducted safely and efficiently.
