nuclear energy energy that can be liberated by changes in the nucleus of an atom (as by fission of a heavy nucleus or by fusion of light nuclei into heavier ones with accompanying loss of mass).
Share. By Andrew Zimmerman Jones. Definition: Nuclear fusion is a nuclear reaction in which two light nuclei (such as hydrogen) combine to form a heavier nuclei (such as helium). The process releases excess binding energy from the reaction, based upon the binding energies of the atoms involved in the process.hare. By Andrew Zimmerman Jones.
