Three Mile Island Case Study

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

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

his led to the melting of the fuel and a drastic increase in radioactivity within the reactor coolant.This also resulted in leaks in the coolant system, which led to small amounts of radiation escaping into the environment.[7]

Training should be given in such a way that hazardous situations can be avoided. For example: Lengthening of working day, removal of taking screening breaks etc for meeting deadlines should be avoided. You must ensure that the significant hazards are identified, and that the actual working practices are addressed and if need be, changed so as to reduce any risk. This is both the responsibility of the employer and employee, for example it is the employees responsibility to familiarise themselves with the hazards and risks in their workplace.

Nuclear power plants should not be built due to the biological effects it poses during a meltdown. Radiation is exposed to inhabitants during a meltdown but many people are not aware of the horrific effects. An example of this is explained in the article “Biological Effects on Radiation”. “The higher the radiation dose, the sooner the effects of radiation will appear…this syndrome was observed in many atomic bomb survivors in…1986 Chernobyl nuclear power plant accident…of these, 28 died within the first three months from their radiation injuries. Two more patients died during the first days…” (2012).

It is important to recognise the different responsibilities and approaches of a member of staff, the employer and others in the work setting. For example the employer is responsible to provide PPE and relevant health and safety training free of charge. It is then the responsibility of a staff member to use the PPE and to attend the training. So although the responsibilities are different they are also related and both need to work in order to ensure a high standard of health and safety. The employer provides as safe working environment, however if an accident or incident occurs it requires the efforts of both staff and sometimes others to report this to ensure measures are put into place to reduce any risk associated with the incident or accident. Another example of how health and safety has a linked responsibility can be shown through a member of staff ensuring they provide the relevant fire safety information/instructions to others. It is then the responsibility for others to follow these instructions.

The loudest objection raised by the anti-nuclear groups is that there is "no safe level of radiation." It is also the phoniest. The major sources of radiation are natural and ubiquitous: we are continuously bombarded with radiation from cosmic rays in the upper atmosphere and from naturally occurring radioactive elements in the earth. Compared with these background sources, the radiation from nuclear power plants is negligible.

Base on the census information, Queens and Brooklyn hold the most Chinese population in New York City. Over 70% of the populations are family households; 20% are under 17 years old and over 10% are over 65. Obviously, community church model is best fitting to serve these Chinese families. Between Queens and Brooklyn, there are few major universities in Queens and Long Island. Thus, it is easier to reach out college students in Queens. However, there are more low-income new immigrants residing in Brooklyn because of the less expensive housing comparing to Queens. It is easier to reach out to the grass-roots level there. For the younger and second generation of the Chinese immigrants’ families, they like to move to Long Island to get more space.

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

The Three Mile Island TMI-2 incident had a large impact on world history. It showed America their first glimpse of what can happen with nuclear power, it foreshadowed the Chernobyl incident eight years later, it decreased public opinion of nuclear power, and it increased safety standards for nuclear reactors across the world. Three Mile Island is a nuclear power plant in Southeastern Pennsylvania with two nuclear fission reactors. On March 28, 1979, reactor two suffered a partial core meltdown that caused a widespread radiation scare. Although negligible amounts of radiation actually escaped into the atmosphere, nearby towns were left deserted for a couple days until the media finally got the story straight and the government released an official

     The Three Mile Island accident took place in Middletown, Pennsylvania, on March 28, 1979. During this accident even though there was no meltdown, there was some radioactive gas that was let out into the air. As a result more than 50,000 people were evacuated from their homes (Levine 60-3). The Three Mile Island incident had a major impact on public opinion, the construction of nuclear plants, and the future of nuclear power.

I think Three Mile Island should stay open. Why you might ask, Well there are many reasons why TMI should stay open. This letter is going to explain the reasons why Three Mile Island should stay open. If you don’t know what TMI is it is a nuclear power plant owned by Exelon. Exelon wants to shut it down because they can not turn a profit at the site.

With any large energy producing facility there are risks. The truth is that accidents do happen at nuclear power plants and at other facilities all the time. An example of this was the accident at Three Mile Island in Pennsylvania where there was a partial meltdown in March 1979. More recently was the worst nuclear accident at Chernobyl. Statistical data for 1995, released by the International Atomic Energy Agency early in 1996, indicated that there were a total of 437 operational nuclear power stations in 31 countries with years of experience. Chernobyl was the only plant that injured the public. Thus, judging by the data, that is a good record for a source of energy.
