Three Mile Island in Harrisburg, Pennsylvania, contained the most serious commercial nuclear accident in U.S. history. The events that followed taught the U.S. a lesson learned about nuclear power and the damage it can cause. The Three Mile accident paved the way for reforms in the way nuclear power plants were operated and regulated. the location of the island, the accident, the meltdown, the aftermath, and the media circus were all critical points in the lessons learned. The location of Three Mile Island is in the Susquehanna RIver, some ten miles southeast of Harrisburg, Pennsylvania. The station is located on eight hundred and fourteen acres on an island surrounded by farmland. The Three Mile Island Nuclear Generating Station…show more content…
The electrical failure caused the operator to not know that the valve was still open, which led to cooling water pouring out of the valve and caused the reactor core to overheat. As a result of all of these things, the instruments that the operators read to know what was happening provided confusing information. The operators could not tell how much coolant was in the reactor core because they didn't have an instrument to show that, but instead had to guess on how much coolant there was. As the alarms and warning lights went off, the operators didn't realize that the plant was having an accident with the coolant level. The tubes holding the nuclear fuel began to melt since they became over heated which also caused fuel pellets to melt. Even though this was the most dangerous kind of nuclear accident, the radiation did not reach outside of the containment building nor did it release out into the environment. There were no immediate injuries or deaths reported from the raditation to the faculty workers. There was a report that got out to the news that there was a meltdown of one of the reactor cores. According to the U.S. Nuclear Regulatory Commissions independent Rogovin Commission Report, the reactor was about half an hour away from an irreversible meltdown as it was described in the movie The China Syndrome. This movie came out just days before the near meltdown happened and was about the same things that happened on Three
