In April 1986, a nuclear disaster caused the evacuation of approximately 200,000 people from the cities of Chernobyl and Pripyat. Twenty-seven years later, there are still inhabitants of Chernobyl, though Pripyat, a city closer to the site of the accident, is reportedly uninhabited. Due to the large scale of this event, some may not wish to believe that this disaster was not intentional, but many sources indicate otherwise. Some will be surprised to learn that the Chernobyl disaster was caused by a safety test. In actuality, there was concern that if there was a power outage, the core of the reactor would overheat and allow tons of radioactive material to escape into the atmosphere. There were several safety features to prevent this, but they were almost all controlled electronically. So, in order to test the safety of the machine, the operators brought the reactor to almost half power and shut down one of the turbo generators, as only one was needed. The mistake was, arguably, in shutting down the emergency core cooling system, or the ECCS. Its purpose was to shut down and cool a reactor during crisis conditions. However, operators were worried it would inject coolants into the extremely hot reactor and damage it, so they went against international safety laws to keep it disengaged during the safety test. As the test went on, the operators shut down yet another safety feature in order to lower the level of power. It was dropped down to a dangerous level, but the operators were told to keep the experiment running. Later, orders came through to disable the safety feature that sensed when water levels were too high. Eventually, this caused a situation in which the operators were required to shut the reactor down, but fearing the l... ... middle of paper ... ...., n.d. Web. 1 Jan. 2014. Deadly Secret- Russia.

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
Imagine working with radioactive materials in a secret camp, and the government not telling you that this material is harmful to your body. In the book Plutopia: Nuclear Families, Atomic Cities, and the Great Soviet and American Plutonium Disasters by Kate Brown, she takes her readers on a journey to expose what happened in the first two cities that started producing plutonium. Brown is an Associate Professor of History at the University of Maryland, Baltimore County. She has won a handful of prizes, such as the American Historical Association’s George Louis Beer Prize for the Best Book in International European History, and was also a 2009 Guggenheim Fellow. Brown wrote this book by looking through hundreds of archives and interviews with people, the evidence she found brought light to how this important history of the Cold War left a nuclear imprint on the world today.
In 1917 a young female right out of high school started working at a radium factory in Orange, New Jersey. The job was mixing water, glue and radium powder for the task of painting watch dials, aircraft switches, and instrument dials. The paint is newly inventive and cool so without hesitation she paints her nails and lips with her friends all the while not knowing that this paint that is making them radiant, is slowly killing them. This was the life of Grace Fryer. Today there are trepidations on the topic of radiation from fears of nuclear fallout, meltdowns, or acts of terrorism. This uneasiness is a result of events over the past one hundred years showing the dangers of radiation. Although most accidents today leading to death from radiation poisoning occur from human error or faults in equipment, the incident involving the now named "radium girls" transpired from lack of public awareness and safety laws.

...d them to end the war with Japan. But not only did they create bombs, but they also found a new way to power the spreading cities of America. Also, even though many knew the power of a nuclear bomb, they couldn’t have predicted the lasting effects on the land and the people. So within this scientific experiment we have learned that nuclear radiation can cause genetic mutations, the formation of cataracts, leukemia, and a shortened life (Document I).
Chernobyl (chĬrnō´byēl) is the 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. Included in the release were radioactive elements with a half-life of 16 million years. Yet, we humans cannot defe...
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.
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...

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

The energy industry is beginning to change. In today’s modern world, governments across the globe are shifting their focuses from traditional sources of power, like the burning coal and oil, to the more complex and scientific nuclear power supply. This relatively new system uses powerful fuel sources and produces little to no emissions while outputting enough energy to fulfill the world’s power needs (Community Science, n.d.). But while nuclear power seems to be a perfect energy source, no power production system is without faults, and nuclear reactors are no exception, with their flaws manifesting in the form of safety. Nuclear reactors employ complex systems involving pressure and heat. If any of these systems dysfunctions, the reactor can leak or even explode releasing tons of highly radioactive elements into the environment. Anyone who works at or near a nuclear reactor is constantly in danger of being exposed to a nuclear incident similar to the ones that occurred at the Chernobyl and Fukushima Daiichi plants. These major accidents along with the unresolved problems with the design and function of nuclear reactors, as well as the economic and health issues that nuclear reactors present serve to show that nuclear energy sources are not worth the service that they provide and are too dangerous to routinely use.
Although boundary crossing often yields enlightening results that lead to progression, it is necessary to mention that there are times it can lead to disaster or disorder. In regards to the events at Chernobyl, the ambition of the engineers involved is commendable, yet they disregarded safety protocols that could have protected the world from such a devastating accident. To articulate this, Blackwell describes, in a darkly comedic
