Nuclear power is energy which is produced with the use of a controlled nuclear reaction. Many nations use nuclear power plants to generate electricity for both civilian and military use, and some nations also utilize this type of energy to run parts of their naval fleets, especially submarines.
How Nuclear Energy Plants Work. As with coal, oil, or gas-fueled plants, nuclear power plants use heat and steam to generate power. Nuclear energy is created from the splitting of uranium atoms in a process called fission. Fission releases energy that can be used to make steam, and the steam is used to power a turbine to generate electricity.
