On April 1986, Soviet's Union Chernobyl nuclear plant exploded letting out a massive amount of radiation that would debate of all Russian citizens for hundreds of years to come. At exactly 1:21 am. on April, 1986 inChernobyl, a city near the Pripiat River the No. 4 reactor exploded and released thirty to forty times the radiation of the Nagasaki and Hiroshima bombing. The exact causes of the explosion are not known , however scientists and researchers, under thorough investigation, have uncovered possible causes to the explosion.1 The main reason why the explosion occurred was that, the operators of the plant were attempting to conduct an experiment with the emergency cooling system turned off, they made six fatal errors which sealed everyone's fate. Soviet officials clamed that if the technicians, would have avoided at least one of those mistakes, then the plant could have been saved.
The technicians began the test one day before the explosion. They started reducing the reactor's power level so they could run the turbine experiment. However in order for the plant to run at lower power they had to turn off the automatic control system, which powered all emergency limitations that the plant should make in case it goes out of control. Turning of the cooling system was an unnecessary action and though it did not cause the explosion, it made the consequences more fatal. Just then the operator's receive a call from the local grid controller in Kiev, who needed the power and asked the technicians to stop lowering it, at what they obeyed. Once that was done the reactor was running with out the cooling system , which was a very serious mistake. At 11:10 p.m. the grid controller said he no longer needed the power, and the operators returned to reducing the power. At twenty minutes past midnight the operators forgot to set the regulator properly, it was the second fatal error. Because of the incorrect regulator settings the reactor's power crashed to 30 MW from...
