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…show more content…
This would have perhaps managed to contain the situation and less consequence would have incurred. There was also the case of certain parties which had failed to follow the chain of command. The prime minister’s office did not announce a state of emergency in the short time after the accident. The designed emergency response was for the emergency response unit to be the medium of communication between the prime minister’s office and the plant operator,TEPCO.This is to ensure that the prime minister’s office is well-informed regarding the situation.But in this case, the prime minister’s office communicated directly with TEPCO and the Fukushima Daiichi power plant. This clearly shows the incompetence of the authorities to follow the procedures. 2.2 Industrial process and operation Fukushima Daichi Nuclear Power Plant consists of six nuclear reactors and the types are the boiling water reactors (BWR). These reactors are light water reactors and they were all designed by General Electric (GE).These reactors have a total of 4.7 GW in power to drive the electrical generators. Reactors for units 1, 2 and 6 were supplied by GE whereas units 3 and 5 were supplied by Toshiba and Hitachi supplied the unit 4. 2.2.1 Working Principle of BWR The BWR’s working principles is as such, the reactors heats the water, which then
