Chernobyl: One of the Greatest Accidents the World Would Learn From

1714 Words7 Pages
The world has seen numerous engineering disasters and from each one, has gained insight to better prepare for future calamities. However, it is very difficult to fully foresee how an accident might occur just by looking back to past disasters. In addition, it is even harder to prepare for something that hasn’t even happened before. The Chernobyl accident is a prime example of an event that couldn’t be fully prevented just by looking to past disasters or even predicting this exact accident. Psychological biases, as well as other contributing factors such as human factors, and design flaws made the Chernobyl accident a catastrophe that no one could have anticipated. The series of events that occurred on April 26th, 1986 at the Chernobyl…show more content…
One thing led to another, and the chemical reactions demolished the reactor building (Anerup). There were countless opportunities to stop the test before thing got out of hand. There were also as much signals as there were opportunities that, if taken into consideration, could have prevented this disaster. The disaster at Chernobyl didn’t transpire just from one factor but rather from several factors. One of the factors was a psychological bias, more specifically overconfidence. It made sense for the plant to run a test on the reactor; it’s a part of maintainability. However, they made a poor choice in shutting off the emergency core cooling system. They failed to think about what would happen if the test failed in such a way that it really needed the emergency core cooling system, which it ironically did. They were too confident in thinking that the test would go as planned. Similar tests were conducted in 1982, 1984, and 1985 all of which failed (CNN IReport). They felt that they could redeem themselves by running the test one more time in 1986. Most likely, this was a key motivation in making this test as successful as possible. Another factor was human factors, more specifically poorly conducted operation. It seemed as soon as one thing in the operation started to go wrong, it just started a chain reaction of poor decisions. The power of the reactor at the beginning of the test should have been “about 700-1000 MWt prior to shutdown, but possibly due to
