Nuclear power stations generate electricity by using nuclear reactions, typically through a process called fission. In fission, the nucleus of an atom, usually uranium-235 or plutonium-239, splits into smaller parts, releasing a large amount of energy in the form of heat. This heat is used to produce steam, which drives turbines connected to generators, ultimately producing electricity. These power stations are designed with multiple safety systems to prevent accidents and contain radiation. While they produce low greenhouse gas emissions during operation, concerns about radioactive waste management and the potential for nuclear accidents, such as the Chernobyl disaster or Fukushima Daiichi incident, remain significant issues in the energy debate.
