  • 4. Working Principle NUCLEAR CHAIN REACTIONS Fission Fusion Atom Bombs work on FISSION reaction
  • 5. NNUUCCLLEEAARR FFIISSSSIIOONN  Nuclear fission is the splitting of one heavy nucleus into two or more smaller nuclei, some sub-atomic particles, and energy.  A heavy nucleus is usually unstable due to many positive protons pushing apart.  Small changes of mass = huge changes in energy  When fission occurs:  Energy is produced.  Neutrons are released.
  • 6. Nuclear Fission A nuclear chain reaction May be triggered by a Single neutron.
  • 7. Nuclear fission is what occurs in nuclear power plants and atomic bombs
  • 8. First ATOM BOMB test  The first atomic explosion was conducted, as a test, at Alamogordo, New Mexico, on July 16, 1945.  The energy from the explosion was equivalent to that of 20,000 tons of TNT.  It was dropped for testing purposes only.  Maximum at 500 kilotons of TNT.
  • 9. Atom Bomb Types Little Boy WWII brought the first use of the atomic bomb for military action. The bomb, nicknamed “Little Boy,” was dropped on Hiroshima, Japan, on August 6th, 1945. Even though it was a smaller atomic bomb, it still managed to kill over 65,000 people, and injure almost 70,000. The total area of destruction was one mile in diameter.
