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 this accident’s cause, but it comes down to either natural disaster or man-made disaster. The effects of this accident were tremendous in the aspect of social, ecology, sociology and health hazards. There were steps taken to assist in resolving the issue .In future, to prevent this kind of accident from taking place, proper safety measures should be implemented along with higher level of knowledge in running a nuclear power plant. 2. Introduction
A massive earthquake with a magnitude 9.0 and convoying tsunami hit the Tohoku region in eastern Japan on March 11, 2011. It was then that the Fukushima Daiichi Nuclear Power Plant has been facing a calamity due to the power loss that resulted from the meltdown accidents. Three buildings which was housing nuclear reactors were entirely damaged from hydrogen explosions, and in one building, the nuclear reactions became out of control. The nuclear power plant is run by TEPCO. TEPCO is one of the leading companies in providing electrical power in Japan. They operate about one third of electricity in Japan. Nuclear usage is popular in Japan to produce electricity. It is relatively cheap as compared to using coal and fuel. The Fukushima nuclear plant has six Boiling Water Reactors (BWR) and these reactors were designed by General Electrics (GE). The problem was the tsunami had destroyed certain units of reactors; alternative power source and this caused the cooling system to fail. This report aims to look into the causes of the accident, whether it was naturally occurring or human made. Also there will be a brief description about industrial process and operations of the nuclear power plant. Next, will be the impact of the accident on Japan in certain aspects. Moreover, the actions taken by the corresponding authorities were also discussed. Finally, the effective preventive actions were discussed as well, to avoid this catastrophic disaster in future. This case study is essential in order for me to learn and know about the nuclear power and the consequences of it.
2.1 Case analysis
On March 11, 2011 Japan was hit with a catastrophic accident in the form of a tsunami with a magnitude of 9 and measuring 14 metre. Due to this, the Fukushima Daiichi nuclear power plant suffered leakage of radioactive substances into our atmosphere. Even though this accident was initiated by natural causes, the cause can’t be regarded as such. It was more of a man-made tragedy that had shocked the entire world. The regulating body and the operator for the nuclear plant were inefficient in performing their duties, which includes an assembly of errors and intractable neglect.
Japan is an earth quake and tsunami prone country which has a long history of this catastrophic events occurring. The authorities governing the nuclear power plant should have known that this will affect the safety level of the plant and appropriate actions should have been taken to ensure a minimal effect in the event that these disasters should happen. The administrative and governing authorities have failed to provide the basic security necessities by means of gauging the possibility of obliteration, organizing for containing collateral damage from such a disaster and...
