Nuclear Fission is a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy.

 Nuclear Fission: Basics |
 Controlled Nuclear Fission |
"To maintain a sustained controlled reaction, for every 2 or 3 neutrons released, only one must be allowed to strike another uranium nucleus. If this ratio is less than one then the reaction will die out; if it is greater than one it will grow uncontrolled (an atomic explosion). Nuclear reactions are controlled by a neutron-absorbing material, such as graphite. "1 |
