By the time the operator noticed, and try to shutdown the reactor, it was already under an extremely unstable condition. A wrong and weird design of the control rod caused a sudden increase of power when they were inserted into the reactor. The interaction between hot fuel and cold water caused the fuel to break down and with the steam and increase of pressure. It results to the reactor’s destruction. The image is took back when the Chernobyl nuclear power plant exploded. Large amount of steam spread through the core and caused steam explosion, and released the fission and radioactive product to the atmosphere. Few seconds later, another second explosion released broken parts from fuel channel and hot graphite. There are two workers died because of the explosion. The graphite and fuel started fire, and eventually caused the main release of radioactivity to the environment. When the explosion happened, two radionuclides, cesium 137 and iodine 131 were released. As we said, the two type of radioactivity would cause an effect on the human health. (World Nuclear Association, 2015) It was happened on 26 April, 1986, and the fire continued for ten days.

The first bomb dropped in Hiroshima was called Little Boy, and it was mainly made out of isotope U-235. Once there were enough U-235, the scientist used a gun-type design. (Atomic Heritage Foundation, n.d) The bomb was dropped on 8:15 in the morning, exploded above Hiroshima about 2,000 feet. This bomb was basically equal to 12- 15,000 tons of TNT. (History, n.d) After three days, on August 9, American bomber drop another bomb at Nagashima, and killed nearly 39,000 people.
