Three Mile Island Photo: United States Department of Energy In March ofan undersea earthquake sent tsunamis thundering across Japan, killing nearly 20, people and creating the most expensive natural disaster in history. Among the casualities was the Fukushima Daiichi Nuclear Power Plant, which was almost completely submerged by the tsunamis; an unprecedented event. Power was lost obviouslycooling systems stopped, and the net result was a complete meltdown of three of the plant's reactor cores.
The events that followed taught the U. The Three Mile accident paved the way for reforms in the way nuclear power plants were operated and regulated. The station is located on eight hundred and fourteen acres on an island surrounded by farmland. The second generator, also known as TMI-2, is the one that failed during the accident.
Even though the accident occurredthe island still created energy plentiful amounts of engergy for Pennsylvania. The island is concreted now, but produced 6. The island was hardly known to anyone until the accident occurred which brought up many concerns of health and safety problems.
Many people today still do not know where the island was and what its purpose was. Three Mile Island produced a significant source of energy for Pennsylvania and surrounding areas whenever it was running. On an early morning of March 28,around 4: The generator became really hot because the water supply that cools down the generator was shutoff.
This caused pressure in the primary system to increase and in order for the pressure not to get to excessive, the pilot-operated relief valve opened up. 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 tubes holding the nuclear fuel began to melt since they became over heated which also caused fuel pellets to melt.
Negative Aspects Of Nuclear Power Plants. Print Reference this. Disclaimer: As witnessed in the Three Mile Island disaster, when uranium is not properly cooled it can reach temperatures high enough to allow it to melt through it’s container causing the possible release of radioactive material into the environment. If you are the. Nov 27, · Meltdown At Three Mile Island (Nothing Compared to Fukushima). Nuclear Meltdown Near Los Angeles - Duration: Disaster at Chernobyl Discovery Channel (). The accident at the Three Mile Island Unit 2 nuclear power plant near Middleton, Pennsylvania, on March 28, , was the most serious in U.S. commercial nuclear power plant operating history. Even though it led to no deaths or injuries to plant workers or members of the near by community, it did.
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. 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 Mile Island. Reports indicate that ninety percent of the reactor core was damaged and fifty-two percent of it had meltded down.
The containment building and several other locations around the plant were contaminated. Officials were able to save the reactor from a complete meltdown by restoring enough coolant to the reactor core.
As a result, the number two reactor was shutdown permanently and the first reactor was shutdown but resumed operation in The aftermath of the Three Mile Island accident was what made everything so intense.
The accident showed people how groups of people under lots of stress, react and make decisions from under it. Many people think that the accident went so far because operators made incorrect decisions because of the large amounts of information that was given to the during the accident.
The equipment that was used at the plant was also used at other power plants and were shutdown due to the accident. The cleanup for the accident took almost a decade because of the radiation that got out in the containment building where the reactor core was at.
It took nearly six years before a power plant tried to get permission to build another nuclear plant or have another reactor put at one of the plants already built.The Three Mile Island Disaster: An Organizational Communication Study Essay - The accident at the Three Mile Island Unit 2 nuclear power plant near Middleton, Pennsylvania, on March 28, , was the most serious in U.S.

Tokaimura Criticality Accident Based on activation products in coins from houses near the plant boundary and about m from the reaction, it was estimated that some mSv of neutron radiation would have been received by any occupants over the full period of the criticality.
