How a nuclear plant works

A nuclear power plant creates energy that turns water into steam. The steam turns a turbine that is connected to a generator that produces electricity. Meanwhile, the steam is converted back to water and returned to the reactor core. Inside the reactor core are fuel rod contains pellets of uranium dioxide. Nuclear fission occurs inside the fuel rods, releasing thermal energy that turns the water into steam. To prevent overheating, control rods are inserted into the reactor core.
