On Friday March 11th 2011 at 2:46 pm, Japan’s Eastern coast was hit with an earthquake of a 9.0 magnitude. Following the quake, an 18 foot tsunami was triggered causing the pre existing damage to be even more sever. The tsunami caused the AC power to disable in 3 of the plants, which kept the cooling system from working. As a result, hydrogen in the exploded in the fuel rods which stated the release of the large amounts of radioactive material into the surrounding area.The quake and tsunami alone caused 15,893 people to lose their lives. Not only did this devastate the country when it happened, but the disaster is still affecting not only Japan, but surrounding areas, such as the Pacific ocean and parts of the U.S.
On March 11, 2011, Japan was hit by an earthquake and a tsunami resulting in 15,894 confirmed deaths, with 2,556 people missing. This was the fourth strongest earthquake to hit in recent years with a magnitude of 9.1 (“Damage Station Police” ). However, this was not the only disaster to have struck Japan, the combination of the earthquake and tsunami led to the meltdown of a power plant in, Tōhoku region, Japan. This event became known as the Fukushima Daiichi nuclear disaster. Nuclear meltdowns has contributed harm to many environments by radioactive leaks, soil contamination, and radiation exposure.
A huge earthquake with size of 8.9 has struck the northeastern coast of Japan on March 11, 2011. It was the fourth greatest in present recorded history. The few minutes of earthquake trigged massive tsunami, as high as thirty meters destroying 500 kilometers of Japan northeastern coast. Effect of the earthquake and tsunami incited a nuclear disaster in one of the few nuclear power plants along the eastern coast—Fukushima Daiichi, had and worked by the Tokyo Electric Power Company (TEPCO). The Fukushima Daiichi plant consolidated six nuclear reactors, three of which were in operation, with the rest encountering routine upkeep. All reactors close down successfully immediately imitating the
On March 11, 2011, a 9.0 magnitude earthquake damaged a large portion of the eastern coast of Japan and formed a tsunami that caused nuclear reactors to become unstable. These three nuclear reactors that became unstable, made an already devastated place turn into a very hazardous place to be. The tsunami alone did insurmountable damage to the buildings on the east coast, this also resulted in thousands of people’s deaths. The tsunami blocked multiple roads and highways, cut off water and electricity for millions of households, and created an unfortunate situation for the Fukushima Daiichi Nuclear Plants. The nuclear power plants and the tsunami created a national crisis in Japan
This paper will address how the Fukushima Nuclear Power plant violated the following NSPE Canons of Engineering Ethics: holding the paramount of safety, health, and welfare of the public, and avoiding deceptive acts. The misjudgment and underperformance by the engineers during the 2011 Tohoku Earthquake caused a large uproar of rejection towards nuclear power in Japan, which could have been prevented if the engineers had not misconducted before the events.
Chemical accidents can happen anywhere, and anytime. That is one of the reason it is very important to be safe and cautions when you are working in the lab area. Regardless of what supplies you might be using that day. Not too long ago there was a major nuclear accident that took place on March 11, 2011 in Japan. It was known as the Fukushima accident.
Fukushima was the second worst nuclear disaster in the history of the world. Contamination can spread through air, dust, trash, wildlife, and of course water. TEPCO reported that around 300 tons of contaminated water had leaked in to the ocean. By April 15, 2011 radiation levels were 6500 times the legal limit. Cod and pollock are important because of their global demand. Cod has tested positive for radiation contamination more than once since the disaster, not only in the Fukushima area, but in many other areas too. 70% of domestic product comes from the Pacific Ocean. This has led to a lot of negative information circulating through Japanese society and a shortage of positive information (or at least an indifference to it). Negative
The destruction of the Fukushima Daiichi nuclear power plant in March 2011, caused by an earthquake and subsequent tsunami, resulted in massive radioactive contamination of the Japanese mainland. In November 2011, the Japanese Science Ministry reported that long-lived radioactive cesium had contaminated 11,580 square miles of the land surface of Japan. Approximately 4,500 square miles – an area almost the size of Connecticut – was found to have radiation levels that exceeded Japan’s allowable exposure rate of 1 mSV (millisievert) per year. For perspective, 1 mSV is equivalent to 100 milliRem, which is the standard unit of dose used here at the shipyard. In a normal background radiation field, an individual is exposed to .02 milliRem/hr dose. Studies of the disaster have identified design changes, response actions and other safety improvements that could have reduced the amount of radioactivity released from the plant. As a result, nuclear plant safety requirements around the world have been reexamined, including here in the United States.
This caused reactors 1 through 3 to go into a meltdown and it created a situation where Japan was on the brink of a major environmental disaster. To fully understand the different events there will be a focus on: factors that caused the meltdown, why this did not impact the other three reactors, the consequences, who is responsible and how these incidents can be prevented in the future. Together, these elements will highlight the underlying effects of this disaster and its impact on the region. ("Fukushima Accident")
The article I have chose to read and write about is, Impact of the Fukushima accident on marine life, five years later. In the article it is stated that about five years ago the largest single release of human-made radioactive discharge to the marine environment resulted from an accident at the Fukushima Daiichi Nuclear Power Plant in Japan. The article states that approximately eighty percent of the fallout happened over the Pacific ocean. The article then discusses how a new study explores the environmental consequences in the marine environment of the accident. Lastly the article outlines the status of the current research about the impact of the fallout on plant and animal life and what remains to be done as the radioactivity continues to spread.
The earthquake made the nuclear leak, and the nuclear leak not only affected the human activities, but also affected the environment as well. The nuclear radiation affects the soil and the sea around the station. Many fish died and the sea was polluted.
Lastly, a look into the effects Fukushima has played in our atmosphere. A study published December 29th, 2014 by the Proceedings of the National Academy of Sciences confirmed that wind from ocean currents carried radiation all the way from Japan to the United States. The radiation is in the water vapors that make up our clouds, resulting in tainted precipitation. The radioactive fallout was and is being carried throughout the atmosphere. The transportation from the atmospheric effects is the umbrella over every other
Fukushima catastrophic is a warning to the world about the hazards of nuclear power and contained lessons for the other governments who plan new generation of nuclear power stations. First lesson is the full disclosure on potential risks and share creditable information with the public. Furthermore,
On 11th March 2011 Fukushima, Japan was struck by a 9.1 magnitude earthquake which initiated a tsunami, as well as the damage of the Fukushima Daiichi Nuclear Reactor, creating a nuclear disaster. Japan is located at a plate boundary region, which makes earthquakes a common occurrence. From this Fukushima suffered from environmental impacts such as the contamination of food, health conditions such as thyroid damage as well as an impact on the economy that put Japan into even more debt. Since the disaster, Fukushima has undergone 128 more Earthquakes, indicating that the area in which Fukushima is located is prone to more future Earthquakes. Although these earthquakes cannot be predicted, technology such that assist in the Dilatancy Theory may help to determine if an earthquake is about to occur, through generalized patterns of activity. In the event of another earthquake systems like Earthquake Early Warning can help to alert citizens that may be in danger, to ensure that the number of fatalities is lower than Fukushima.
