Nuclear energy is created during a fission or fusion, and is typically used to generate electricity. Nuclear power plants use the fission or fusion reaction to create the nuclear energy, which generates heat. This heat the power plants use to transform the heat energy into electricity. Fission is where large nuclei are split into smaller nuclei. Fusion is where the small nuclei are put together to create large nuclei. These two reactions create nuclear energy.
