  1. Nuclear Fission By Julie Shooshanian & Liv Jaho

  2. What is nuclear fission? • The splitting of the nucleus into two pieces is known as nuclear fission. This often can produce photons in the form of gamma rays, free neutrons, as well as subatomic particles. Reactions on various elements may differ. For example, fission of heavy elements can release large amounts of electromagnetic radiation.

  3. What is it used for? • A use for nuclear fission is to produce energy for nuclear power. It also can drive the explosion of nuclear weapons. This is because certain substances known as nuclear fuels endure fission when hit by free neutrons. After this happens, it produces neutrons.

  4. What are fission reactors? • This is the most common type of nuclear reactor. Power reactors are meant to produce heat for nuclear power (nuclear submarine.) Research reactors are meant to produce neutrons or activate radioactive sources for research purposes. Breeder reactors are meant to produce nuclear fuels in large amounts from isotopes.

  5. History • In 1919, the first person to actually execute nuclear fission was Enrico Fermi. He did this by combining nitrogen and alpha particles from a radioactive material. He observed a photon being released with a higher energy than the alpha particle. • “The fundamental point in fabricating a chain reacting machine is of course to see to it that each fission produces a certain number of neutrons and some of these neutrons will again produce fission.” - Enrico Fermi
