Bang, crash boooommm!!!! It came from reactor 4. No one thought it was coming. But when it did …. Wait wait, wait, I’m getting ahead of myself, let's go back to the start of all of this. First I’m going to tell you how a nuclear power plant works. How one of the greatest nuclear disasters this world has ever seen happened, and how someone was able to survive this great nuclear disaster known as Chernobyl. I myself think that to everybody at that time was shocked and surprised that something like that could happen, because there had been nothing on that scale before.
How does a nuclear power plant work? Okay let's start out with the basics of how a nuclear power works. You have a nuclear reactor, tubes that carry superheated radioactive

April 26, 1986, it was a beautiful warm evening with a clear night sky. The government had demanded the plant run some diagnostics on reactor 4. They wanted to see if the reactor could run on low power and see if the reactor could sustain power under the stress of making power for a pump. At 1:20 am the testing began, shortly after the test started the generator could not handle the extra stress, it began to heat rapidly, they tried to insert the uranium control rods with graphite tips to help slow down the process, but it caused power levels to rise dramatically instead of lowering the fission reaction. So the water had heated so rapidly, causing the steam pressure to build, that it had blown up the tanks on the roof and causing the roof to collapse. Then it blew the 30,000 metric ton cap off of the reactor. Following the explosions, tons of radioactive dust was shot into the atmosphere. That radioactive dust set into motion the devastation that affected workers and townspeople, those effects can still be seen to this …show more content…
He was supervising the testing of reactor 4 when he noticed things going horribly wrong. All of the monitoring equipment went to Defcon 5, alarms began sounding ,the workers began retreating to the bunkers. Sasha was in the doorway of the control room making sure his coworkers got into the safety of the bunker. Sasha and other workers did not make it to the bunker before the reactor blew at 1:23 am, 3 minutes after the testing began. After the explosion Sasha went to look for his co-workers who didn’t make it to the bunker, he saw 2 vaporized bodies by the reactor, one of them being his colleague Khodemchuk. First responders began showing up to the scene shortly after the explosion. Firefighters tried to battle the flames and fire, they were unable to get the fire under control for 10 days. By 6 am Sasha Yuvchenko could no longer walk, he started to vomit uncontrollably and his skin started to turn violet black. He went the hospital and he was sent straight to Moscow with 128 other people with radiation poisoning. The right side of his body where he had leaned up against the doorway to the control room had the most exposure to radiation. He had microsurgery in Berlin and later had to have part of his arm amputated. He spent 3 years in hospital having multiple surgeries and therapies, with some bumps along the way. The Right side of his body was covered
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,”
Many of them were human impacts. One impact for example was that from the years 1963–1979, the number of reactors under construction globally increased every year except 1971 and 1978. However, following the event, the number of reactors under construction in the U.S. declined every year from 1980–1998. This was of course encouraged by the accident. Many reactors were even cancelled. 57 nuclear reactors were cancelled from 1980-1984. The world still has a lot of nuclear reactors because of this accident though. Even though it was a turning point, it made us more aware of the dangers and then we could build safer and more modified power
The Meltdown happened at 1:23 AM, beginning a fire that scattered vast amounts of radioactive materials into the air. The measure of radioactive material discharged was 400 times more than the sum the nuclear bombing of Hiroshima discharged. The aftermath was being recognized in all parts of Europe, especially some parts in Asia.
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...
As soon as “Little boy” made contact with the ground everything was destroyed and the impact made a burning bright white flash which incinerated people to either walls or the ground. This light, black rain, ionized radiation, and much more ended up making the air 300,000 degrees Celsius. “ Only the skeletons of a few buildings made from reinforced concrete survived” (George Feldman 409). After the big blast was over, it seemed like the worst had passed, but then it started to rain black radiated water. It contaminated food, water, and the air. People who consumed this got radiation poisoning and died with families left to dread their losses within the last
Nuclear energy is produced during the process named nuclear fission or nuclear fusion. The development of nuclear energy started in the 20th century and there is now worldwide recognition for using nuclear energy. Popular countries that operates nuclear power are United States, France, Japan, and Russia, the nuclear energy generates up to 6% of the world’s electricity supplies. Even though the energy is mostly used by many countries, but it may causes side effect to the living things in the environment. (WNA, 2012)
"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.
Nuclear power has grown to be a big percentage of the world’s energy. As of January 18, 2013 in 31 countries 437 nuclear power plant units with an installed electric net capacity of about 372 GW are in operation and 68 plants with an installed capacity of 65 GW are in 15 countries under construction. As of end 2011 the total electricity production since 1951 amounts to 69,760 billion kWh. The cumulative operating experience amounted to 15, 15,080 years by end of 2012. (European Nuclear Society) The change that nuclear power has brought to the world has led to benefits in today’s energy’s usage.
To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”). This chain reaction produces massive amounts of heat. Nuclear reactors take advantage of this heat by pumping water into the reactor, which in turn produces steam. The steam then becomes pressurized through a pipeline and exits into a turbine (“How do Nuclear”). The pressurized steam causes the turbine blades to spin, producing power which is linked to a generator for use in the main power lines. When the steam passes the turbine blades, it goes past cooled pipes and condensates (“How do Nuclear”). After the condensation process is finished and the steam reverts back to water, it is pumped into the reactor again, thus completing the process of producing nuclear-based power.
mental degradation. The mass production of goods, in manufacturing industries, more so has led to a lot of pollutants being released into the atmosphere. These pollutants continue to degrade the environment. There are several forms of pollutions that continue to be heavily experienced as a result of the activities of Multi-National Corporations. The two most adverse types of pollution are water pollution and air pollution. They affect a lot of the systems that are in play.
Imagine that you are reading a fictional book, you have been reading it for hours and the main character dies. You have become so invested with the book and so you begin to cry, but why would you feel so emotionally impacted if the character is fictional. Fiction seems to have the ability to impact different aspects of our lives and bring up various emotions even when we know that it fictional. Fiction can influence individuals to behave and feel certain ways, when we read books or watch films we gain emotions and build attachments to characters.
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.
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)
Nuclear power, the use of exothermic nuclear processes to produce an enormous amount of electricity and heat for domestic, medical, military and industrial purposes i.e. “By the end of 2012 2346.3 kilowatt hours (KWh) of electricity was generated by nuclear reactors around the world” (International atomic energy agency Vienna, 2013, p.13). However, with that been said it is evident that the process of generating electricity from a nuclear reactor has numerous health and environmental safety issues.
