Early the morning of April 26, 1986, the nuclear reactor at the fourth unit of the U.I.Lenin power station at Chernobyl exploded. This blast made history. The nuclear accident in Chernobyl was the worst in the world. Knowing how the accident happened, why people were not aware of it, and the results of the accident, can help to prove the thesis. The chain of events leading to disaster began on the morning of April 25, 1986. Unit Number 4 was scheduled to be taken out of service for routine maintenance. The plant=s electrical engineers wanted to conduct a test to figure out how long the turbine-generators would continue to produce electricity to run the water pumps necessary to cool the reactor after the normal electrical supply had been interrupted. At one A.M., the reactor=s power level was lowered to prepare for the test. Then, over the next twenty-four hours, technicians systematically disconnected power regulation and emergency cooling systems that would have automatically shut the reactor down and interfered with the
test. Finally, at 1:23 on the morning of April 26, 1986, they halted the flow of steam to the turbine. Almost immediately, the cooling pumps slowed, diminishing the flow of cooling water to the reactor core, triggering an uncontrolled chain reaction. Reactor Number 4 exploded. There were two blasts, three seconds apart. A deadly plume of radioactive material shot into the air (Nardo 58). It seems that this happened very quickly. There was almost no time to react. One thing occurred after another within the same minute. Imagining what was going through the minds of people who were there is hard. They were probably really afraid and wanted to get out of there as fast as possible. It is probably hard to think during a disaster like this. A person does not know what to do. Should they panic and run, or should they stay calm and try to deal with the problem. A person could go insane just thinking of what to do. Soviet leaders had known enough about the disaster when it happened. They could have treated it as a major crisis and
