    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.
