| Also Known As | Nuclear fission and fusion, atomic energy reactions, nuclear energy release |
What is Nuclear Fission?
The splitting of a heavy nucleus into two lighter nuclei with release of energy and neutrons. Fission of U-235 or Pu-239 is triggered by neutron absorption. The process releases enormous energy (Einstein's E=mc²) and is the basis of nuclear reactors and atomic weapons.

Nuclear fission: currently used in ~440 nuclear power reactors worldwide and in naval nuclear propulsion. Nuclear fusion: provides the energy of the sun and hydrogen bombs; ITER (International Thermonuclear Experimental Reactor) project aims to achieve net energy fusion for power generation. Both ar…
Nuclear fission: produces highly radioactive fission products, requires containment, cooling, and radiation shielding; accidents (Chernobyl, Fukushima) demonstrate catastrophic potential. Nuclear fusion: produces mostly neutrons and helium, far less radioactive waste; the plasma and magnetic systems…
