Nuclear energy is the energy that is stored in the nucleus (nucleus is another word for center or core) of an atom. The sun and other stars produce energy from nuclear energy. Nuclear energy is used to produce electrical energy in nuclear power plants. Nuclear energy is a concentrated form of energy. When the nucleus of an atom splits apart, a lot on energy is released.
