What is Fission?
The splitting of a heavy atomic nucleus (such as uranium-235 or plutonium-239) into two lighter nuclei, releasing a large amount of energy and neutrons. Nuclear fission is the basis of nuclear power plants and atomic bombs. The released neutrons can trigger chain reactions.

The splitting of a heavy atomic nucleus (such as uranium-235 or plutonium-239) into two lighter nuclei, releasing a large amount of energy and neutrons. Nuclear fission is the basis of nuclear power plants and atomic bombs. The released neutrons can trigger chain reactions.
Nuclear fission is the energy source in nuclear power reactors (generating ~10% of world electricity), in naval propulsion, and in nuclear weapons. Fission products (I-131, Cs-137, Sr-90) are used in medicine and research but are also the primary radiological hazard in nuclear accidents.
Fission produces intense neutron and gamma radiation, extreme heat, and highly radioactive fission products. Reactors require multi-layered containment, active cooling, and passive safety systems. Nuclear weapons and criticality accidents are catastrophic. All fission work requires stringent nuclear…
