Nuclear power plants are a type of power plant that uses the process of nuclear fission to generate electricity.
They use nuclear reactors in combination with the Rankine cycle, where the heat generated by the reactor converts water into steam, which spins a turbine and a generator.
The nuclear reactor is a key component of a nuclear power plant, as it contains the fuel and its nuclear fission chain reaction, along with all of the nuclear waste products.
A chain reaction refers to a process in which neutrons released in fission reaction produces an additional fission reaction in at least one further nucleus. This nucleus, in turn, produces neutrons, and the process repeats. The process may be controlled like in nuclear power or uncontrolled as in nuclear weapons.
Uranium is the dominant nuclear fuel used in nuclear reactors, and its fission reactions produce the heat within a reactor. This heat is then transferred to the reactor's coolant, which provides steam to the turbine of the nuclear power plant.
