1. Abstract
The earthquake which took place on March 11, 20111 in the Tohuku District, Japan triggered a massive tsunami which eventually caused a nuclear power plant outbreak. The tsunami, 14-metres in height struck the Fukushima Daiichi nuclear plant, which is located in the towns of Okuma and Futaba in the Fukushima Prefecture. This resulted in loss of power to the reactors of Units 1, 2 and 3.Along with this damage, the cooling system failed to work and there were hydrogen explosions which ended in damaging the nuclear plant. The damages also include extensive release of radioactive substances into our atmosphere and our earth. This accident certainly did loads of damages to Japan and its people. There are lots of theories regarding

These turbines are linked together and there is a long shaft connecting them to the generator. Electricity is produced by the generator, which is transferred to a transformer, which increases the electrical power. In the reactor’s core, nuclear fission creates heat and then the cooling water boils, creating steam. After the steam is used to operate a turbine, it flows into condensers which are below the low pressure turbines.Here, the steam is cooled off and changes form into water. Using pumps, the water is pumped in to the reactor vessel. Inside the reactor’s core, the water cools off the fuel fabrications by pumps operated with electrical power. In case of emergency, and the plant losses electric power supply, water is supplied by other set of pumps, operated by diesel generators.

2.3 Impact of the Fukushima nuclear disaster The Fukushima nuclear disaster was the worst accident of a nuclear plant since the Chernobyl incident in 1986.Japan was in a grave shock as it involved matter of life and death. The impact of this accident can be seen in various ways to Japan and its people. Here are the various forms of the impact.

2.3.1 Society The Japanese society was tremendously affected by this disaster. Those who were living within 20 km radius from the plant, government agencies told them to evacuate hours after the accident. People within the radius of 25 -30 km was initially told to stay indoors and not to
