What Is Nuclear Fission? - Definition & Process The splitting of a nucleus into fragments is accompanied by a very large release of energy. Nuclear power plants use nuclear fission to generate power. The nuclei of uranium atoms, as well as the nuclei of other large atoms, can undergo nuclear fission naturally.

- Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. It is usually in a form of heavy metal, naturally occurring in most rocks, soil, and even in the ocean!

- Nuclear stability means that nucleus is stable meaning that it does not spontaneously emit any kind of radioactivity (radiation). On the other hand, if the nucleus is unstable (not stable), it has the tendency of emitting some kind of radiation, i.e., it is radioactive.

- Nuclear energy. The energy that is released during a nuclear reaction. Splitting atoms (fission) and fusing atoms (fusion) both release nuclear energy. Today's nuclear power plants use fission to produce energy, which allow them to generate electricity on a large scale. nuclear reactor produces electricity in much the same way other power plants do. Some form of energy creates heat, which turns water into steam. The pressure of the steam turns a generator, which produces electricity.

nuclear Usage The words nuclear and atomic mean the same thing when referring to weapons or to the making of power: We say nuclear (or atomic) weapons and nuclear (or atomic) energy. But in most scientific uses nuclear and atomic mean different things. Nuclear is used to refer to the nucleus of an atom, where the protons and neutrons are located. When a radioactive element gives off a neutron, for example, we call this a nuclear event.
