A nuclear power plant is a facility that generates electricity using nuclear reactions. It primarily relies on the process of nuclear fission, where the nucleus of an atom, usually uranium, is split into smaller parts, releasing a significant amount of energy. This energy is used to heat water, producing steam that drives turbines connected to generators. The main components of a nuclear power plant include the reactor, where fission occurs, and the cooling system, which helps manage the heat produced. Safety measures are crucial in these plants to prevent accidents and protect the environment, ensuring that operations are conducted safely and efficiently.
