Now, the three examples, Chernobyl, Fukushima, Three mile islands, show the effect of the nuclear accident. Each has different causes, but the damages were terrible. Chernobyl Disaster Brief Description On April26, 1986, the nuclear power plant was exploded in Chernobyl, Ukraine. At 1:23 AM, while everyone were sleeping, Reactor #4 exploded, and 40 hours later, all the city residence were forcefully moved to other cities, and they never return to their home. The Chernobyl disaster is ranked the worst nuclear accident. The Chernobyl nuclear power plant was ran by the Soviet Union central nuclear energy corporation. (International Atomic Energy Agency-IAEA, 2005) Causes There are two possible causes. The first one is that the operator’s error. The turbine was exploded while it was testing, and the operator ignored the rules and regulations. The operator turned off the technical protection systems, and all the safety barriers. It was happened, because of insufficient education and training, and it caused the lack of knowledge of nuclear reactor. He just ignored the steps of test, and chose the dangerous short cut to finish the test quickly. The other possible cause is incorrect operating instructions and design. This argument announced in 1992. Both possible causes were lobbied from different groups. And Soviet Union did not offer enough data; therefore still the exact cause is veiled. (IAEA, 2005) Damage The biggest damage is the radiation exposal to the people. 530,000 local recovery workers were exposed the radiation, the effective dose is same as fifty years of natural radiation exposure (IAEA, 1996). 31 nuclear power staffs and emergency workers were died by direct effect, and the Chernobyl Forum anticipates the total num... ... middle of paper ... ...d out the leakage a year later. Another cause of the disaster is that government ignored the chance of tsunami. Scientists warned about the dangerousness of tsunami, and advised them to build more protection to tsunami threatening. However, the government did not consider the advise (IAEA, 2011) Damage The radiation released through ground, air and sea. Around 20 kilo meters of regions from the nuclear power plants was contaminated , and the residents 20 to 30 km from the nuclear power plant were asked to leave the region. The polluted coolant goes to the Pacific Ocean, which is very dangerous, because human being is the placed at the top on the food chain, therefore, the fish consumption may result the cancer. Pacific Ocean is the biggest fishery in the world, and Japan’s fish consumption per person is highest in the world (Mccurry, 2014). Effect of the disaster
The engineers in Visit Sunny Chernobyl created a new frontier past the safety zone because they want to test the limits of the reactor. What the scientists didn’t account for is that fact that the reactors already had the potential of a dangerous chain reaction. (Blackwell 6) Consequently, their boundary destroying led to catastrophic consequences and the total annihilation of a land area because of massive radiation. Blackwell thought Chernobyl was so horrific he expressed that no one should visit without a “working understanding of radiation and how it’s measured” (Blackwell 7). These are some horrific consequences that followed from surpassing the
...r. Iodine 131, another radioactive element, can dilute very quickly in the air, but if it is deposited on grass eaten by cows, the cows then re-concentrate it in their milk. Absorbed into the body's thyroid gland in a concentrated dose, Iodine 131 can cause cancer. In the Chernobyl disaster, the biggest health effect has been cases of thyroid cancer especially in children living near the nuclear plant. Therefore, because of the Chernobyl disaster we know to test the grass, soil, and milk for radiation. Also, an evacuation of the Chernobyl area was not ordered until over 24 hours after the incident. Japanese authorities evacuated 200,000 people from the area of Fukushima within hours of the initial alert. From the mistakes and magnitude of the disaster at Chernobyl, the world learned how to better deal with the long and short term effect of a Nuclear Fallout.
On April 26th, 1986, operators at the Chernobyl Power Plant in Chernobyl, Ukraine, ran what they thought to be a routine safety test. But fate was not on the side of these operators. Without warning, reactor #4 became unstable, as it had been operating at a low power for a possible shutdown and the reactor’s design caused it to be unsafe at this level of power. Internal temperatures rose. Attempts to cool the system produced the opposite effect. Instantly, the nuclear core surged with power. At 1:23 p.m., the reactor exploded. The first blast ripped off the reactor's steel roof. The second blast released a large plume of radiation into the sky. Flames engulfed the building. For ten long days, fire fighters and power plant workers attempted to overcome the inferno. Thirty-one of them died of radiation poisoning. Chernobyl was the worst nuclear disaster in history. It unleashed radiation hundreds of times greater than the atomic bombs exploded over Japan during World War II. [1]
In April 1986, The Chernobyl Nuclear Reactor melted down and virtually exploded releasing a huge quantity of radiation, covering the western region of the Soviet Union in nuclear fallout. The Soviet Government immediately had to evacuate the civilians in the now contaminated areas around Chernobyl. The entire city of Pripyat numbering about 45000 people were evacuated and relocated the very next day after the explosion. “By 14 May, some 116,000 people that had been living within a 30-kilometre radius had been evacuated and later relocated” (World Nuclear Association). All in all, numbers into the millions were affected by the Chernobyl reactor explosion, whether it was direct contact with high doses of radiation as one of the 1000 firefighters who were first on the scene to the children of men who worked and lived in the city of Pripyat. Thousands to hundreds of thousands of people evacuated never see their homes again and unknowingly leaving the wasteland to return to its natural state.
Hopefully, with accurate analysis and innovation, my research will teach the world of its past so this disaster doesn’t occur in the future. B - Summary of Evidence Chernobyl (chrn byl) is an uninhibited city in north Ukraine, near the Belarus boundary, on the Pripyat River. Ten miles to the north, in the town of Pripyat, is the Chernobyl nuclear powerstation, site of the worst nuclear reactor disaster in history ("Chernobyl", Columbia Encyclopedia). To specify, on April 26, 1986, Unit Four of the Chernobyl nuclear reactor exploded in Ukraine, injuring human immune systems and the genetic structure of cells, contaminating soils and waterways. Nearly 7 tons of irradiated reactor fuel was released into the environment—roughly 340 million curies.
"Chernobyl" is a nuclear reactor accident occurred in the Chernobyl nuclear power plant in Ukraine. The accident was by far the most serious nuclear disaster. It pollutes the many areas around and increases the incidence of cancer around the inhabitants. Since the Chernobyl accident, the Soviet Union suffered a heavy blow disaster, while enhancing the worldwide nuclear power industry for safety concerns, and slowed the progress of a series of nuclear power engineering. Disaster occurs mainly due to the failure of the reactor design, and employee carelessness and violation of the rules. The response to the disaster was also not adequately handled and this increased casualties, but lacking of information and the government reluctant to recognize
The original INSAG report stated that the main cause for the disaster was the workers failing to perform operational procedures properly. However, a later revision on that report established that the actual cause was attributed more to the reactor design. This change does not diminish the fact that training and safety practices of the workers created issues leading up to the disaster. Both the training and safety issues are rooted in the fact that the workers were not properly informed in certain key areas including operational regulations and basic nuclear physics. By not providing this knowledge, the management failed to establish a safety culture for the workers [13]. Safety culture is a term used to describe how an organization views and prioritizes safety in its work [14]. This lack of a safety culture stems from a “lack of adequate training of the operators, inadequate permanent operating procedures, lack of enforcement of the rules and incomplete and imprecise instructions for this [...] low power test” [15]. This disregard for safety began to show itself even before the test ...
I. (Gain Attention and Interest): March 11, 2011. 2:45 pm. Operations at the Fukushima Daiichi Nuclear Power Plant continued as usual. At 2:46 pm a massive 9.0 earthquake strikes the island of Japan. All nuclear reactors on the island shut down automatically as a response to the earthquake. At Fukushima, emergency procedures are automatically enabled to shut down reactors and cool spent nuclear fuel before it melts-down in a catastrophic explosion. The situation seems under control, emergency diesel generators located in the basement of the plant activate and workers breathe a sigh of relief that the reactors are stabilizing. Then 41 minutes later at 3:27 pm the unthinkable occurs. As workers monitored the situation from within the plant, citizens from the adjacent town ran from the coastline as a 49 foot tsunami approached. The tsunami came swiftly and flooded the coastline situated Fukushima plant. Emergency generators were destroyed and cooling systems failed. Within hours, a chain of events led to an explosion of reactor 1 of the plant. One by one in the subsequent days reactors 2, and 3 suffered similar fates as explosions destroyed containment cases and the structures surrounding the reactors (Fukushima Accident). Intense amount...
Every since the industrial revolution, society has moved to jobs, factories, manufacturing goods and products, and larger cities. This process called industrialization is when an economy modifies its way of living from an agriculture based living to the production of merchandise in factories. The manual labor that is required for farm work is replaced with mass production on assembly lines. Andrew Blackwell visits this idea of industrialization in Visit Sunny Chernobyl but to a higher extent. Blackwell states “today that society is an industrial one, resource hungry and plant-spanning, growing so inefficiently large, we believe that it is disrupting its own host… It’s not just about living sustainably. It’s about being able to live with ourselves,”
Chernobyl is the only nuclear meltdown to have people die as a result of radiation leakage and radiation poisoning.

While the early warning saved thousands of people, the Japan’s Meteorological Agency underestimated this earthquake as the subduction zone of Japan should not produce the magnitude 9.0 quake (Oskin, 2013a). The Tohoku Earthquake and its tsunami approximately killed 16 thousand people, injured 6 thousand people and around 3 thousand people were missing. Most people died from drowning. Around 300 thousand buildings, 4000 roads, 78 bridges, and many more were affected by the earthquake, tsunami, and fires from leaking oils and gas. Electricity, telecommunication, and railways were severely damaged. The debris of 25 million tons was generated and carried out to the sea by water (BBC News, 2012). The country’s authorities estimated more than 309 billion US dollars of damages. Landslides occurred in Miyagi and liquefaction in Chiba, Tokyo, Odaiba, and Urayasu (USGS, 2013). Furthermore, the tsunami destroyed protective tsunami seawalls. Approximately 217 square miles of Japan covered in water (Oskin,
Chernobyl is one of the most environmental catastrophic events in history. The event has caused many environmental problems that will never be able to be recovered, inclduding the fauna, vegetation, and ground waters; however surprisingly there has been a change in the last years including the sightings of many animals thats habitats were destroyed from the event. Chernobyl nuclear disaster was the worst nuclear accident in the world, and is one of only two listed as a level 7 event, which is the highest number, the other being Fukushima Daiichi nuclear disaster. The disaster began when two completely untrained scientists did a test on one of the reactors, during the test the power surged causing a flame to ignite to radioactive material, eventually causing the meltdown. Over 200 million people were evacuated from Pripyat. The explosion itself only killed a few people but the long-term effect of the radiation has killed over 300,000 people including 200,000 firefighters, who put there life on the line to contain the radiation.
There was a multitude of causes of the disaster in Japan. The first cause was a 9.0 magnitude earthquake that occurred off the coast of Japan. Japan is located in “The Ring of Fire,” an area in the Pacific Ocean that has multiple faults and earthquakes (Pedersen 13). Tectonic plates shifted off the North Pacific coast of Japan and created a massive earthquake. The next cause was a thirty-three foot wall of water that swept over cities and farmland in Japan (Branigan 2). Martin Fackler, a journalist, stated, “The quake churned up a devastating tsunami” (Fackler 3). The tsunami reached speeds of 497 miles per hour while approaching Japan (Fackler 3). The third and final reason of the disaster was that the cooling systems at multiple nuclear power plants failed. At Fukushima, a nuclear power plant in Sendai, Japan, the radioactive rods began to overheat due to the absence of water, which cools it. Explosions occurred at three of the reactors, which spewed radiation into the air (“Comparing nuclear power plant crises”). In conclusion, the earthquake, tsunami, and nuclear power plant issues were the causes of the disaster in Japan, but they also had a myriad of effects.
