WebWhat Is Nuclear Fission? When the nucleus of an atom splits into lighter nuclei through a nuclear reaction the process is termed as nuclear fission. This decay can be natural spontaneous splitting by radioactive decay, or can actually be simulated in a lab by achieving necessary conditions (bombarding with neutrinos). http://hyperphysics.phy-astr.gsu.edu/hbase/NucEne/U235chn.html
