Nagasaki Atomic Bomb expanded the mainstream of atomic bomb and nuclear electric power

   The continuous photographs were captured immediately after the plutonium type atomic bomb exploded on 11:02 am on 9 August 1945 while the Nagasaki Atomic Bomb was dropped. Nuclear fission was a process in which unstable nuclei of plutonium (Pu) collapse are split to generate lighter elements. Just after explosive surrounding the atomic bomb ruptures, the center of plutonium is compressed at once, absorbing the neutrons released and chain reaction of nuclear fission at a stroke. The power of the nuclear fission corresponded to 22,000 tons as a TNT bomb. Repeated fission within the atmosphere and the ability to terminal destruction was estimated to be 35% for heat rays, 50% for blasts and 15% for radioactivity. Nuclear fission of Nagasaki Atomic Bomb remained 5 tons of Plutonium that the contaminated radioactivity was generated and sprayed into Nagasaki City. Spherical Fat-Man type with 32 tetrahedral lens which caused explosive waves to make the early explosion coincide with the arrival point of slow explosion. The coincidence strongly compress the central part of Plutonium was First developed and produce for the first time in the world. The most difficulty ,time and money was took during the Manhattan project. Atomic Bomb and nuclear electric power generation by Plutonium type were expanded into the mainstream in the world  at the most.
