The first commercial nuclear power plants were constructed in 1950. The public was promised a non-polluting and resourceful type of energy. Although there are less than 500 nuclear power plants in the world, but many nuclear accidents have already been endangering civilian lives, such as the accidents in Three Mile Island, Chernobyl, and the most recent Fukushima Diichi. Nuclear energy may appear to be the ideal source of energy for the future. However, there are uncontrolled situations that cause the reactor into meltdown and lead to disaster. On March 11, 2011 Japan experienced an earthquake, which has become the most terrible and destructive in the history of this country. In term of geography, Japan is situated in the earthquake-prone area, on the junction of four plates: the Eurasian, Pacific, North American and Philippine. The Eurasian plate is slowly moving to the east, and three others – to the west, so their friction causes earthquakes. Japanese know about the danger based on their country geography, but they were not ready for this kind of disaster. A 9.0 magnitude earthquake struck at 2.46pm about 70km east of Tohoku at an offshore subduction zone, where two tectonic plates collide and one slides beneath the other. According to IBT news, Its centre was on the seafloor at a 24km depth, this earthquake was so powerful it shifted Earth on its axis of rotation. The energy released by the earthquake produced a huge tsunami, with waves up to 30ft beginning to hit the
