Three Mile Island Effect

This research paper discusses the Three Mile Island incident to include what started it, the results in the aftermath, and how it could have been prevented. The Three Mile Island Unit 2 (TMI-2) reactor, near Middletown, Pa., partially melted down on March 28, 1979. This was the most serious accident in U.S. commercial nuclear power plant operating history, although its small radioactive releases had no detectable health effects on plant workers or the public. Its aftermath brought about sweeping changes involving emergency response planning, reactor operator training, human factors engineering, radiation protection, and many other areas of nuclear power plant operations. It also caused the NRC (Nuclear Regulatory Commission) to tighten and

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.

This accident has been, by far the worst nuclear power plant accident within the borders of the United States.However, the studies conducted by governmental groups such as the Nuclear Regulatory Committee (NRC), the Environmental Protection Agency, the Department of Health, Department of Energy, and the State of Pennsylvania as well as numerous independent organizations have deemed that the accident at Three Mile Island had very little, if an at all, effects on the health of the communities surrounding the plant.[8]

As humans we want to have a good life, have a home, maybe a family and feel safe. With the advances in industry such as energy production we can have more luxuries which include heat, lights and running water. However, as technology gets bigger and better there will always be risks that can lead to catastrophic outcomes. Luckily for the United States; we did not have a disastrous outcome with a nuclear power plant such as the 1986’s Chernobyl Nuclear Power plant catastrophe, making, ”the Chernobyl disaster the only level 7 incident on the International Nuclear Event Scales (INES) making it the biggest man-made disaster of all time” (List 25, 2014) . Three Mile Island power plants is located near Middletown Pennsylvania. On March 28, 1979, the plant had a partial meltdown. Even though the Three Mile Island power plant incident did not have any adverse health effects, Three Mile Island had an impact on the nuclear industry development and politically in the United States.

On March 1979, in Harrisburg, Pennsylvania Three Mile Island there were misread gauges and poor decision that lead to the melting of the core reactor. But after the core melted

Radioactive waste/radiation and environmental causes and changes are the two main causes of safety hazards. Radiation is harmful because it can kill people or deform parts of their bodies and when having a baby, the baby can get deformed in the arms legs, or other body parts. This happened at Chernobyl were the reactor’s blew up and radiation got to pregnant women and their babies became deformed and people that were close or in the nuclear power plant died. Then also if you want to make the place livable again, you had to remove the radiation from the explosion and you would have to if it was a major explosion, remove the radiation from the site somewhere else so it wouldn’t spread to the other countries or states. One other thing is that terrorist want to blow up the nuclear power plants to cause the same destruction that happened at Chernobyl. Environmental causes and changes are a huge part in why we should shutdown Three Mile Island. Environmental causes are animals getting hurt because of what nuclear is power plants have to do to get uranium. Mining uranium is dangerous in many ways. Uranium produces radiation, so when mining it the radiation spreads into the forest where animals get contorted or they die. This also happens when the nuclear power plant takes about one billion gallons of water per day and marine or aquatic animals start to die because of the loss or drought of

On Wednesday, March 28, 1979, around 4 a.m., there was a failure in the water pumps at the Three Mile Island in Middletown, Pennsylvania. This led to a partial meltdown of a nuclear power plant. The Environmental Protection Agency (EPA), the Department of Health, Education and Welfare (now Health and Human Services), the Department of Energy, and the Commonwealth of Pennsylvania all conducted particular studies of the radiological consequences of the accident. Approximately two million people were estimated to have received an average of one millirem of radiation, and there was a maximum dose to a person who was at the site of 100 millirem (“Backgrounder”). To put this into perspective, an exposure from a single chest X-ray is two to six millirem (“Doses”). However, this put fear into the minds of politicians and others all across the country. What the people do not know, though, is nuclear is better. Instead of using fossil-fuels and wind power, America ought to switch to nuclear energy to power the country because it is safer, cleaner, less expensive, and more reliable than the current ways of producing energy

Three Mile Island Unit 2, located near Harrisburg, PA, had an automatic shutdown, even though the plant’s efficiency level rated about 100 percent. On March 28, 1979, one of the reactor pumps, used to supply cooling water, stopped operating, causing an automatic shutdown. This triggered an

Many of the same ineffectual workers that had worsened the incident, were mistakenly sharing conflicting data and misinformation with both government officials and the press. Rumors of deadly doses of radiation being released onto the public began to swirl as a byproduct of the confusion. Nearly 140,000 frantic citizens fled the area in the days that followed. State officials advised the remaining citizens to refrain from venturing outside of the home, and recommended farmers in the area to herd their livestock into shelter. The governor of Pennsylvania, Dick Thornburgh, even went far as to take the precautionary measure of issuing the evacuation of all pregnant women from the area. Without as much as single death or injury linked to the Three Mile Island incident, a petrified America became united under fear. In a matter of days, the seemingly visionary road leading to the age of nuclear power was entirely weathered away, and the people now wanted

On March 28, 1979 a series of mechanical, electrical, and human failures led to what has been described as the worst nuclear power plant accident in the history of the United States. News of the accident rocked the nation, and its effects were keenly felt by those who lived in the shadow of the great concrete towers of Three Mile Island.

The description of the three-mile island that is located in Dauphin County in Pennsylvania, which as a nuclear power plant. On March 28th, 1979, an accident occurred because of the failure of the core nuclear reactor. The mechanical failure by the human error, stopping the flow of water through the pumps that would have cooled down the heat generating process inside the core reactor and might have stopped this major hazardous incident from occurrence. Accordingly, the turbine generator and the nuclear reactor as stopped responding. However, prevention of the flow of water leads to building of excessive heat and steam because it was too high pressure for the reactor to sustain. Thus, the hazardous radioactive steam was

In Pennsylvania, the worst nuclear power plant accident in the United States occurred. Nuclear power plants generate a mass of electricity using steam generators. The plants are very controversial concerning their safety with the environment and its role with unstable reactants like uranium and plutonium. On March 12, 1979, someone at the Three Mile Island’s second reactor, or TMI-2 for short, left a relief valve wide open leading large amounts of nuclear reactant cooling to the main reactor. All of the coolant leaving TMI-2 was recognized by the control panel in the plant but was disregarded as a loss that typically happens. At first, the surrounding towns were told that the incident wasn’t anything of worry. But after a couple days

history took place on March 28, 1979 at the Three Mile Island plant in Pennsylvania. A cooling system failed, causing a partial meltdown, but a full meltdown was averted and there were no fatalities. However, despite the positive outcome and despite the passage of more than 30 years, the incident remains fresh in the minds of those who are old enough to remember it.

A huge part of why people oppose nuclear energy is because of the safety issues that come with nuclear reactors. The Hill is a news agency that has written an article on nuclear safety and the accidents that have recently happened. They also took a poll on how many Americans favor nuclear energy and how many favor it who live in cities with nuclear reactors. They state:

Three Mile Island nuclear plant is located in Pennsylvania, United State. The accident began on 28 March, 1979, a core meltdown in TMI-2 reactor. According to accident report, it was attributed by both human factors and mechanical failures: Something wrong happened in TMI-2’s secondary system, and resulted in a series of failures. The pilot-operated relief valve (PORV) automatically opened, but did not closed, which led coolant water to escape. The operator misread the situation and did not take proper actions in the first place due to inadequate training. The accident finally led to the release of about 2.5 million curies of radioactive gases, and 15 curies of radioiodine.
