A nuclear power plant captures the energy created by the fission of the nuclei of uranium atoms and uses the generated energy to boil water. The boiled water creates steam that spins a series of turbines as it rises. As each turbine spins, it generates power that is sent into the power grid. Choose the correct sequence to fill in the blanks below. The uranium atoms contain __________ energy. The heat from their fission increases the __________ energy of the water. The spinning of the turbines is __________ energy that then generates __________ energy used in people’s homes.
