Chernobyl & Fukushima Nuclear Disasters The Chernobyl & Fukushima nuclear disasters are similar in many ways, but yet so very different. Lets explore these two disasters, the events that took place, the amounts of radiation released, the effects on the people and the land, and how each disaster was handled then and still being handled now. Let’s first look at the similarities; both Chernobyl and Fukushima are the only two nuclear power disasters that are ranked as level seven events. The International Atomic Energy Agency has a scale for nuclear accidents and a level seven event is the direst rating. In both of these accidents the governments of each country underestimated the problem and in some cases are still underestimating the effects …show more content…
Studies are still being done at both sites and radioactive material is still being monitored. Now let’s look at the history, facts, and differences of both the Chernobyl and Fukushima nuclear disasters. Starting with the Chernobyl disaster, on April 26, 1986 a nuclear power plant in the Ukraine caused a major catastrophe for the nearby people. As plant workers were testing the reactor units, unit four was destroyed therefore releasing a number of unsafe radioactive material into the environment. People of the immediate radius were not the only people affected by this reactor unit explosion. As radioactive material was released into the air, the wind spread these materials all throughout parts of the Ukraine. Plant workers, emergency response teams and residents of the nearby areas were all at risk. Large amounts of …show more content…
Government resources have a lot to do with the clean up process of any nuclear disaster. The Soviet Union was in financial trouble during the Chernobyl disaster so vast amounts of contaminated land were left abandoned and the land is still that way today. At the time of the Fukushima disaster, Japan had the resources to clean up the contaminated land and to keep those evacuated housed in other places while the cleaning process is done. Although nuclear power is inexpensive, provides around the clock “base-load” power, and a low-carbon source of energy there is always going to be the threat of another nuclear disaster with radiation
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
The Hanford Nuclear Site, a highly radioactive site that contains two-thirds of the country's waste by volume. The site is known for making plutonium for the atomic bombs dropped on Japan in World War 2. We will be covering the activities within the Hanford Nuclear Site from the beginning to the present and the involvement of the United States government. The nuclear site has many mysteries and unanswered questions, but this is what is available. The activities within the Hanford Nuclear Site are a mystery, but the information released to the public is what is available.
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]
Countless engineering disasters have occurred in this world, many civilians lost their lives due to corrupted constructions. The most fatal and deadly engineering disaster that took place in our history was the Chernobyl disaster. The Chernobyl catastrophe was a nuclear setback that happened at the Chernobyl Nuclear Power Plant in on April 26, 1986. It is seen as the most recognizable terrible nuclear power plant cataclysm ever. A nuclear crisis in one of the reactors caused a fire that sent a cluster of radioactive consequence that on the long run spread all over Europe.
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.
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...
"The tops are leaping off the reactor lip" this was the first warning which the control room received before the destructive explosion in Chernobyl that occurred at 1:23 AM local time. Twenty three minute after the warning in the morning of 26 April 1989, the reactor exploded. The Chernobyl nuclear accident was an unexpected catastrophe that can happen in the history of producing nuclear power. International Atomic Energy Agency (IAEA) defined a nuclear accident as an accident that includes any activities that lead to the release of radioactive material and causes significant consequences. The location of Chernobyl city is in the north of Ukraine near the Belarus border. That nuclear accident happened when in reactor number 4 in the Chernobyl nuclear power in the Soviet Union exploded. Because of that extreme explosion, the radioactive emissions dispensed into the environment and caused immediate deaths, illnesses and many health problems. World Health Association (2013) reports that during the accident, one person died immediately and another one died in the hospital due to the harmful injuries he received. Health World Organization (WHO) (2006) also reports that a few weeks after the disaster 28 people died because of the Acute Radiation Sickness(ARS). The Chernobyl nuclear accident is one of the major disasters in the history of nuclear power which had many serious effects on humans and the environment.
As of 2013 the Island of Bikini was still determind to be unsafe to live on by the united states because of the radiation. So some things I learned about this operation it was the first to be broadcasted live to the american people. They used these test not only to see the effects but to also learn how to decontaimnate the radioactive material.
Chernobyl was the greatest nuclear disaster of the 20th century. On April 26th, 1986, one of four nuclear reactors located in the Soviet Union melted down and contaminated a vast area of Eastern Europe. The meltdown, a result of human error, lapsed safety precautions, and lack of a containment vessel, was barely contained by dropping sand and releasing huge amounts of deadly radioactive isotopes into the atmosphere. The resulting contamination killed or injured hundreds of thousands of people and devastated the environment. The affects of this accident are still being felt today and will be felt for generations to come.
One of the most significant environmentally damaging instances in history was the Chernobyl incident. In 1986, the Chernobyl Nuclear Plant in Ukraine exploded. It became one of the most significant disasters in the engineering community. There are different factors that contributed to the disaster. The personnel that were tasked with operating the plant were unqualified. The plant’s design was a complex one. The RBMK reactor was Soviet design, and the staff had not be acquainted with this particular design. As the operators performed tests on the reactor, they disabled the automatic shutdown mechanism. After the test, the attempt to shut down the reactor was unsuccessful as it was unstable. This is the immediate cause of the Chernobyl Accident. It later became the most significant nuclear disaster in the history of the
...sted for radioactive elements to find the levels at least 50 times greater than what would be considered natural radioactivity. Could this be proof of an ancient nuclear war in Mohenjo-Daro? Ancient astronaut theorists believe that it is.
Semipalatinsk Test Site happens to be one of the largest in the world and the largest one on the territory of the former Soviet Union, and, generated by hundreds of nuclear tests, it raised issues which require solutions. I will try to cover only a few facets of the problem
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...
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.
...ut. It was caused by a faulty design and poor observance of safety. Fukushima was also caused by a faulty design, considering the area it was built on was susceptible to tsunami. One of the reasons why the Bataan Nuclear Power Plant was closed was because of the strong public opinion against utilizing nuclear energy. If only the people were well informed and not prejudiced against building a plant that would help our economy and ease our poverty a little, then we would probably be a little more successful right now. Another reason is because of the area where the power plant was built—on an earthquake prone area near a volcanic formation, a threat to public health. Again, overall, with proper maintenance, engineering, and expertise, nuclear energy is a very good investment, especially for the Philippines which is in need of a cheap but beneficial source of energy.
