On April 26 , 1986 the explosion occurred at Unit 4 of the Chernobyl Nuclear Power Plant (in Ukraine (then officially the Ukrainian SSR)) , which completely destroyed the reactor. It was a catastrophic nuclear accident. The accident is considered as the largest of its kind in the history of nuclear power , both on the estimated number of dead and injured people and economic damage.
The staff had to test and check : whether the turbines will work out the necessary amount of a residual energy to fuel a special cooling system in case of a sudden power outage , and whether such a system withstand disruptions to an emergency power .
The interruption of the experiment was not allowed , that is why all the safety systems were disabled in advance. In order for experiment to be in a maximum safe conditions , it was necessary to reduce the overall power level of the reactor until at least twenty-five percent. It was found that the capacity of the reactor fell far below one percent . Workers began to slowly disperse the reactor to return it to its previous working state , but the power has increased dramatically after thirty seconds.
And because all emergency systems were disconnected , it was impossible to stop the chain reaction . This led the worst nuclear power plant accident in history. An explosion and fire released large quantities of radioactive particles into the atmosphere. Radioactive material was launched over 8 kilometers into the sky . Only four percent of the reactor’s radioactive material reached the atmosphere , but it was still more than was released by the two atomic bombs dropped on Japan.

« ‘Chernobyl is a word we would all like to erase from our memory,’ said US Secretary General Kofi Annan in a foreword to the report. ‘But,’ he added, ‘more than 7 million of our fellow
human beings do not have the luxury of forgetting. They are still suffering, every day, as a result of what happened.’ The exact number of Chernobyl victims may never be known, he said, but 3 million children require treatment and ‘many will die prematurely’. »

- Energy is an invaluable resource for most of the world. The capabilities we have with this power is astounding, but with this power must come the respect of its handling. During the cold war in soviet Russia, the Chernobyl nuclear power plant was providing the resources of energy throughout the area. On April 26, 1986, the decisions made by Deputy chief engineer Dyatlov and his night staff will bring about one of the worst nuclear incidents in human history. The Chernobyl disaster was the “result of a flawed reactor design that was operated with inadequately trained personnel” and “the resulting lack of any safety culture” (World Nuclear Association)....

- The Chernobyl Nuclear Power Plant On the 25th and 26th of April, 1986, the Chernobyl Nuclear power plant exploded, the explosion held such force that the fireball blew off the concrete roof of the reactor. The Chernobyl power plant is located in Ukraine, 80 miles north of Kiev. The power plant held four reactors, the accident occurred whist the number four reactor was being tested and numerous safety procedures were ignored.... [tags: Papers]

- On April 26, 1986 the entire world’s view of nuclear energy changed forever (Nave Chernobyl, n.d., para. 4). This was because on that day there was a massive explosion at the Chernobyl nuclear plant in Ukraine (part of the USSR at the time). Science can be applied to this event to explain why the plant exploded in the first place. Science can be used to look at how the plant was designed to work versus how it worked at the time of explosion. This event had massive health effects on nearby humans as well as animals and plants in the area.... [tags: radiation, disaster, nuclear power]

- Ralston Hall Mindy Townsend ENGL 1010 8:00 15 October, 2014 The Environmental Impact of Nuclear Power Plant Nuclear power plants do not belong in our world today due the major safety concerns they provide. The topic of nuclear energy has been discussed for the past fifty years; for the longest time, it was an unknown power with untapped capabilities one could only dream of. It was not until the 1940 's that scientist got a better grasp of the technology, and unlocked its potential. Unfortunately, this discovery was not a good thing at the time because nuclear technology was solely used to develop atomic bombs.... [tags: Nuclear power, Chernobyl disaster]

- Since You’ve Been Gone... What went wrong During a routine test on April 26, 1986, reactor number 4 at the Chernobyl Nuclear Power Plant experienced a power surge that triggered an emergency shutdown. The attempt to manage the surge in power and the alarming increase in the core’s temperature caused an even larger power surge. Heat and power output continued to rise until the water used to cool the reactor vaporized, generating massive amounts of pressure. The first explosion caused by the steam inside the reactor was enough to send the 4-million-pound lid of the reactor assembly through the roof of the building....

- After Hiroshima and Nagasaki the world believed that the threat of a nuclear disaster was over. Much to their disarray, Chernobyl proved to be the greatest nuclear disaster to befall upon the earth, with its effects ten times as severe as those in Japan. However, Chernobyl was directly caused by human incompetence as the engineers involved failed to report and analyze the errors evident in the reactors design and safety protocols. This catastrophe will become the precedent for engineers to learn and build upon their mistakes in communication and cooperation The disaster occurred on April 26, 1986 at the Chernobyl Nuclear Power Facility in Pripyat, Ukraine....

- Chernobyl is a name that many people around the world are familiar with. It is the name of the power plant that experienced what is considered to be the worst nuclear power accident in history. The plant is located near the city of Pripyat, Ukraine, which was then a part of the Soviet Union. The Soviet controlled power plant, which provided electricity for much of the northern part of Ukraine, consisted of four nuclear reactors. During an experimental test in one of the reactors, a terrible accident happened that would go on to affect much of Europe.... [tags: Chernobyl disaster, Nuclear power, Nuclear safety]

- The Chernobyl nuclear accident was an accident that had many repercussions and caused many to doubt nuclear power across the world. Chernobyl was caused by many events that lead to the eventually melt down of one of the reactors. There have been many studies on why the Chernobyl nuclear power plant melted down. Some say it was from design flaws with the RBMK reactor. Others say it was due to lack of employee training and lack of knowledge on how to safely and properly run the plant. And also it may have been because there was a lack of safety measures implemented and those that were, were not properly followed.... [tags: Nuclear power, Chernobyl disaster, RBMK]

- "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.... [tags: Chernobyl disaster, Nuclear power, Nuclear safety]

- The lasting effects of Chernobyl The effects of the nuclear disaster that occurred at the Chernobyl Nuclear Power Plant in Pripyat, Soviet Union are still experienced today even though more than thirty years have passed since the event. The event is known as “Chernobyl” and has gone down in history as one of the worst nuclear disasters to have ever occurred. (Hjelmgaard) Approximately 120,000 people lived within a 30- km radius but the radioactive release spread causing even more people to continue to experience effects in the present day....
