On April 26, 1986 the worlds worst nuclear disaster happened just outside the town of Pripyat. Located not too far from the capital city Kiev, Ukraine. According to History.com, More than 70,000 people have suffered from the effects of this disaster. Along with much of the land (18 square miles) around that area will not be habitable for the next 150 years, forcing as many as 150,000 citizens to re-locate permanently. At the time of the explosion, Chernobyl was the largest and the oldest nuclear power plant in the world. With four 1,000 megawatt reactors, one reactor explosion and meltdown could affect hundreds, if not thousands of people. Still, the soviet government tried to cover it up or hide this from its own people, as well as the rest of the world. The Soviet Union initially reported the death of two individuals and requested advice for fight graphite fires. Even as Sweden was starting to pick up dangerous levels of radioactivity, the Soviet Union continued to not take responsibility and warn surrounding nations. It wasn't until years later that the full story is released to the public. “Workers at the plant were performing tests on the system. They shut off the emergency safety systems and the cooling system, against established regulations, in preparation for the tests. Even when the warning signs of dangerous overheating began to appear, the workers failed to stop the test. Xenon gases built up and at 1:23 a.m. the first explosion rocked the reactor. A total of three explosions eventually blew the 1,000-ton steel top right off of the reactor” (History). Failing to stop this test resulted in a ball of radioactive fire billowing into the sky, along with 1,000 ft. flames. The fire lasted for nearly 8 days.

For movies and shows, According to IMDb, the Chernobyl Diaries seems to be the most popular one which revolves around a group of college students who take a tour though Pripyat, only to be stalked and hunted by mysterious creatures. While literature, offers a variety of different titles such as the 1988 Marvel Comic The Meltdown which featured Wolverine and Havok. In conclusion the disaster of Chernobyl was a tragedy that cost thousands of lives. An has effected an entire region of that world. An it will be a very long time before everything will be back to normal there. However it has given us a chance to explore what went wrong, andto make sure it doesn't happen again. An not only that, but as a gamer, I love the S.T.A.L.K.E.R series, and doing this paper has made the games so much better.
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
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]
On April 11, 1950, at 9:38 PM, a B-29 took off from Kirtland Air Force Base (AFB) in Albuquerque, New Mexico. The aircraft was on a mission to deliver a Mark 4 nuclear weapon to the 509th Bomb Wing at Walker AFB in Roswell. The aircraft and its crew of 13 were only in flight for approximately three minutes when the plane crashed into a mountain on Monzano Base, Kirtland AFB. All 13 personnel were killed in the crash. Neither the bomb, nor the high explosive material, exploded from the impact. Some of the explosive material was scattered and burned in the gasoline fire that resulted from the impact. The bomb cas...

When the first bomb was made a site in Alamogordo, New Mexico was chosen as the testing ground. In order for the bomb to explode, all the nuclei of the several grams of Uranium would have to be split. A sphere of Uranium the size of a baseball would cause an explosion that equaled the strength of 15,000 to 20,000 tons of TNT. When the bomb had exploded there was a tower and the explosion had turned the asphalt around the tower into green sand, the sky was extremely bright and seconds after the explosion came a huge blast that sent unbelievable heat across the desert. Also, there was a huge mushroom cloud that reached the sub-stratosphere that was at an elevation of 41,000 feet. 10,000 feet away a soldier was of right off his feet by the force of the shock wave and another soldier stationed five miles away was temporarily blinded. The explosion was able to be herd 50 miles away.
"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.
In 1962, at 11:00:09 pm local time on July 8th, the United States detonated a thermonuclear warhead riding atop a Thor missile at 400 km above Johnston Island at a distance of 826 miles from Honolulu, Hawaii. That night was one that many on the Hawaii Islands would never forget (Berkhouse, 1962). Operation , as the test was code named by the U.S. military, caused the first damage in the United States from an electromagnetic pulse created by a nuclear detonation. Though the damage was not intended or planned, the 1.4-megaton weapon caused “the failure of street-lighting systems, tripping of circuit breakers, triggering of burglar alarms, and damage to a telecommunications relay facility.” (EMP Commission, 2004, p. 4)
Since the invention of nuclear weapons, there have been numerous nuclear accidents around the world. One particularly severe such accident was the Windscale fire. The Windscale fire is considered to have been the greatest nuclear accident in the history of the United Kingdom. It was rated a Level Five on the International Nuclear Event Scale. Quick action prevented most of the serious complications that could potentially have arisen from taking place, but it still may have led to upward of 200 cancer cases.
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.

As workers arrived to the plant around 08:00 h on 17 August 2009, there was no cause for immediate alarm. Of the ten turbines, nine of them were running with a tenth down for routine maintenance. Turbine two, however, was causing significant vibrations as its load varied with electricity demand. At 08:13 h, vibration of the turbine bearing reached a maximum and caused a catastrophic failure. The turbine cover shot up as the 1,000 t rotor shot off of its seat. The newly created hole in the structure allowed water to surge at a rate of 67,600 gal s-1 into the machinery hall and flood the levels below.2 The massive jet of water ripped apart the metal joists which held up the roof over turbines one, two and three. As the roof came down, water continued to flood the plant. Long after the automatic safety system should have been triggered, turbines seven and nine still operated at full speed, causing what were witnessed as large explosions in their vicinity as flooding reached their control panels.
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
