Fukushima Nuclear Meltdown 2011
Introduction
The Fukushima nuclear meltdown disaster on 11 March 2011 was an aftermath of the magnitude 9.0 Tohoku earthquake and the subsequent tsunami. The equipment failures in the power plant led to discharge of radioactive substance into the seawater and atmosphere. It is the biggest nuclear accident since the Chernobyl disaster in 1986. This paper analyze the causes and explain the consequence of the disaster, follow by the ethical issue which arises from the accident and finally draw a conclusion.
Findings
As mentioned in the investigation report carried out by the National Diet of Japan[1] found that on March 11, 2011, the East Japan Earthquake(Tohoku) rated in magnitude 9.0 triggered an extremely serious

It is definitely a manmade disaster that could be foreseen and avoided as mentioned in one of the article from Time magazine[2] The root causes of the disaster were due to the regulatory and operational system of the company. From the report[1], it is found that the regulators and the company have noticed the potential hazard that a total loss of power at the plant might arise if there are tsunami hitting at a certain level. But the company kept on neglecting such imaginable possibility of an enormous tsunami. According to the Wall Street Journal[3], the cooling systems in the reactors 1-4 with older design, as the backup diesel generators and electrical-switching equipment were housed in lightly shielded turbine buildings that were easily flooded by tsunami. Meanwhile, there were organizational problems within the company TEPCO as mentioned in the report[1]. During the accident, the company didn’t plan measure for the Isolation Condenser(IC) agency, also there were no manual or any training procedure. The series of operational problems led to the consequential damage and meltdown of fuel rod and lastly triggered extensive explosion which released substantial amount of radioactive material to the …show more content…
Which mean that the plant had to be built near the sea. In the phrase of construction. Engineers has observed that the site is vulnerable to tsunami even with seawall, but due to the cheaper cost to use seawater cooling, the company continued with the project. The engineer violated HKIE code of ethic [6], engineers should ethically urged to stop the projects that are not safe, no matter what stress on them. Thus, they should call the halt to the project even the company put pressure on them in order to prevent the serious consequences.
Conclusion
This paper has discussed the causes and the ethical issue arise from the Fukushima Nuclear Disaster. After analysis, it is believed that the accident is ‘manmade’ catastrophe that can be foreseen and prevented rather than a natural disaster. The root cause of the disaster was due to the faulty regulatory and operational system of the company TEPCO. The accident also remind engineer should pay attention to ethical issue in workplace. Finally, the Fukushima nuclear tragedy let people began to reconsider nuclear energy’s
The nuclear radiation after will be confined to the space of the facility and not escape and harm the people or environment outside. After contemplating Mitch’s decision, I have come to the conclusion that Mitch’s idea was the best one under those
In chapter four of the novel Wormwood Forest by Mary Mycio, Mycio explains the aftermath of the Chernobyl nuclear reaction, and how it had changed the ecosystem drastically. Chernobyl was a nuclear power plant in Pripyat, Ukraine that was operational during the time of the Cold War. This power plant had a sudden power surge in its reactor Unit 4, which resulted in a devastating incident. This caused large amounts of radioactive materials to be released into the air, and causing a level seven nuclear disaster, the highest level possible. After reading this chapter, it made me consider the bombs dropped on Nagasaki and Hiroshima 70 years ago, and the level seven nuclear disaster in Fukushima, Japan.
The discovery of nuclear energy was one of Japan’s greatest technological advances for renewable energy. Through nuclear fission, Japan was able to provide for its energy needs. However, on March 2011, a 9.0 magnitude earthquake and a tsunami hit the Fukushima Daiichi Nuclear Plant, causing a huge meltdown and devastating Japan. In Evan Osnos’s “The Fallout,” the writer offers an anecdote from first-hand accounts of Japanese individuals who reveal the chaos through their experience. Osnos uses imagery to exemplify the cold tone of the article.
Modulus: 1X Earth Science Name: Leroy (CHAN CHUNG YIU) Staff member in charge: Tim Dempster ID:2183820C Title: The April 1906 San Francisco Earthquake Introduction On April 18th, 1906, one of the worst natural disasters happened in the US history. This first major disaster which is recorded in human history with photography, has a 7.8 magnitude(USGS,2013).A subduction of the Pacific plates pulled into the San Andreas plates with the north-west direction, causing a 400 km(ECSC) rupture line. Huge energy is radiated out of the epicenter which was just 2 miles of west San Francisco, the intensity of the shaking nearly wiped out most of the buildings and structures with a duration of 110s(ECSC), affected around 370,000 square meters(NZH,1906).
The Atomic Bomb in WWII Unethical Dilemma Leonardo McCormick Adventist University of Health Sciences The Atomic Bomb In WWII Unethical Dilemma As all aspects of life-threatening situations can become an unethical dilemma which are then discussed. In order to make a statement we must always be mindful to set aside our personal bias when presenting such materials.
Boxing Day Tsunami Tsunami is defined as a high long wave caused by an earthquake, volcano or a meteor and waves that spot grow larger and larger. How it builds up? Before a tsunami the earthquake happens and the waves grow up to one hundred feet tall. During the tsunami, the waves hit shallow waters and destroy anything in its way. After a tsunami, a large wall of water follows behind it and takes many objects with it back to the ocean.
The article, “Surviving the Tsunami” demonstrates how students Aki Kawasaki, Kana Sasaki, and Fumiya Akasaka persevered through the Japanese Tsunami and how it affected them. The text details that the town of Tokyo, Japan was hit by an earthquake, followed by a devastating tsunami. Aki, Kana, and Fumiya along with other students and a handful of teachers were desperately trying to escape, and made it out alive. They were among the lucky, as their families were safe.
On May 22, 1960, at 9:11 GMT, an earthquake occurred off the coast of South Central Chile, triggering a Pacific-wide tsunami that had a surface-wave magnitude of 8.6, an epicenter of 39.5° S, 74.5° W, and a focal depth of 33 km. May 22 was a day to remember for the people who survived and had to live with the pain forever The tsunami generated in southern Chile and affected Hawaii, Japan, the Philippines, eastern New Zealand, Southeast Australia, and the Aleutian Islands in Alaska. The first waves were less than half a meter high, but three hours later, many oscillations of about 1.5 meters occurred. The source of this earthquake in 1960 extended over a distance of about 1,100 kilometers along the southern Chilean coast.
A tsunami is a series of great sea waves caused by an underwater earthquake, landslide or volcanic eruption. A tsunami is a series of many waves known as wave trains. A tsunami can also be generated by a giant meteor. Most tsunamis are known to be formed by underwater earthquakes.
The Chernobyl Disaster of 1986 The Chernobyl disaster of 1986 was the largest and most catastrophic nuclear explosion in history. It severely effected out environment, people, atmosphere, and animals. Chernobyl caused hundreds of thousands of injuries and deaths, and to think we brought it upon ourselves. Chernobyl use to be a thriving city with many people.
The 2011 Tōhoku earthquake and tsunami caused an immensely colossal number of displaced people. The number of the evacuees, as of 26 January 2012, was 341,411. Some earthquake survivors died in the shelters or in the process of voidance. Many shelters struggled to aliment evacuees and were not medically sufficiently equipped. Quandaries in stabilizing the Fukushima I plant have hardened postures to nuclear potency.
1. Thesis Title Nuclear energy: it's efficiency sufficient to justify danger? 2. Thesis Description Thesis statement: Although nuclear energy has been proposed as a solution for our energy requirements it is not reliable because of issues regarding safety, nuclear waste storage. It is possible in a medium-long period of time to replace it with renewable energies.
Solid progress was being made at the Fukushima Daiichi Nuclear Power in decommissioning the plant and reducing the accumulation of contaminated water. To support the IAEA’s Peaceful Uses Initiatives, Japan has contributed $25 million to be donated across the next five years. More recently, Japan has disbursed from the Initiative’s contributions about $1.2 million to support the IAEA’s regional technical cooperation projects in Africa, Latin America, the Caribbean and Asia-Pacific. Japan encourages the international community to further support the Agency’s activities in the peaceful uses of nuclear science and technology. In addition, in order to reach the goal of safe nuclear energy use, all reactors should comply with safety-related upgrades and should be replaced in case of failure to suffice to the given standards.
While he was CEO, he was promised and highlighted with the signal that the company is seriously concerned on safety. However, during his appointed, he ignored this problem due to cost cutting and aftermath, it was one of the point engaged in this disaster. Secondly, he should have a clear instructor or policy to junior level but he did not have. He did not get it straight to give them clear mission how to
The Tohoku Earthquake was the most powerful earthquake recorded to have hit Japan. The earthquake was a magnitude 9.0 off the coasts of Japan that occurred at 2:46pm on Friday 11 March 2011, which triggered a powerful tsunami that reached the height up to 10.4 meters. A Japanese National Police Agency reported 15,889 deaths, 6,152 injured, and 2,601 people missing, 127,290 buildings totally collapse, 272,788 buildings half collapse, and another 747,989 buildings partially damaged. The Tohoku earthquake and tsunami caused severe structural damage in northeastern Japan, including heavy damage to roads, railways and dams, not to mention fires in many areas. It was the toughest and the most difficult crisis in Japan after the World War 2 leaving
