Study of the Nuclear Disaster of Chernobyl The worst accident in the history of this nuclear power generation occurred on the morning of April 26, 1986. It was at the Chernobyl (Ukraine) nuclear power station in the Soviet Union. At 1:32AM Lieutenant Colonel Leonid Telyatnikov received a telephone call and was told that there was a fire at the nuclear power plant. There were many reasons their plant had backfired. These reasons included human error and poor plant design due to the cold war.
The disaster has had a prolonged effect to environmental and health fields. The total damaged of “The Chernobyl Disaster” is unknown and remain in the process to be accounted for. “The Chernobyl Disaster” had a multitude of chronological variables which led to the mishap. These variables manifested in conjunction to the preparation and execution of a mandatory test on one of Chernobyl's reactors. The horrific execution kindled the catastrophic situation on numerous factors.
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
On April 26, 1986 a nuclear explosion at the Chernobyl Nuclear Power Plant in present day Ukraine caused catastrophic damage. A systems test at a reactor took a turn for the worst when there was a sudden surge of power. Unskilled worker attempted a shutdown but only caused an even greater spike in the power surge. A reactor vessel ruptured and a succession of explosions followed. A total of thirty operators and firemen were killed in a short amount of time.
The explosions and the threat of a radiation leak are troubling, and Japanese engineers and scientists are doing everything humanly possible to contain the situation. (Turk & Bensel, 2011) Additionally, we also learned about the Chernobyl an accident that occurred on April 26, 1986, at the Chernobyl Nuclear Power Plant in the Ukrainian SSR resulting in the release of large quantities of radioactive contamination into the atmosphere.

Some of the radiation spread across northern Europe and into Great Britain. Soviet statements indicated that 31 people died because of the accident, but the number of radiation-caused deaths is still unknown. The same deadly radiation that was present in this explosion is also present in spent fuels. This presents special problems in the handling, storage, and disposal of the depleted uranium. When nuclear fuel is first loaded into a reactor, 238U and 235U are present.
Chernobyl was a result of a reactor design that was not properly operated. The nuclear release occurred while shutting off the power for turbine testing. The reactors were known to be unstable at low levels of power. Two explosions caused the graphite moderator to catch fire, burning for 9 days and releasing all the nuclear power plant's Xenon, half the iodine and cesium and 3-5% of all remaining radioactive material. The radioactive dust particle was carried by wind throughout bordering Ukrainian countries.
The meltdown of Chernobyl's fourth reactor was the result of a series of errors in the reactor design, operations, and a failure to follow established safety protocols. These human errors resulted in more than 400 times the radioactivity of the Hiroshima nuclear bomb being released into the environment (Salge & Milling, 2006). This caused a massive economic, environmental, and human toll to the region. Improved reactor design and proper adherence to safety procedures could have prevented this disaster. The Chernobyl disaster was caused by two part human error.
Some say the explosion was a consequence of the , 1986 a test was run on a reactor at the Chernobyl 4 power plant. An operator went to shut down the reactor but couldn’t because it was in an extremely unstable condition. The unique design of the control rods in the reactor caused a dramatic power surge when they were put into the reactor. When the very hot fuel and the coolant came together it caused a rapid production of steam and increased the pressure in the reactor. The characteristics of the reactor were very sensitive.
Chernobyl is one of the most environmental catastrophic events in history. The event has caused many environmental problems that will never be able to be recovered, inclduding the fauna, vegetation, and ground waters; however surprisingly there has been a change in the last years including the sightings of many animals thats habitats were destroyed from the event. Chernobyl nuclear disaster was the worst nuclear accident in the world, and is one of only two listed as a level 7 event, which is the highest number, the other being Fukushima Daiichi nuclear disaster. The disaster began when two completely untrained scientists did a test on one of the reactors, during the test the power surged causing a flame to ignite to radioactive material, eventually causing the meltdown. Over 200 million people were evacuated from Pripyat.
