Nuclear power stations generate electricity by using nuclear reactions, typically through the process of nuclear fission. In this process, the nucleus of an atom, usually uranium, is split into smaller parts, releasing a significant amount of energy. This energy heats water to produce steam, which then drives turbines connected to generators. The main components of a nuclear power station include the reactor, where fission occurs, and the cooling system, which helps manage the heat produced. Safety measures are crucial in these facilities to prevent accidents and protect the environment, making them a topic of ongoing discussion in energy policy and environmental science.
