The Pros And Cons Of Gulf Oil Spill

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.

In 2010, BP’s Deepwater Horizon rig exploded, causing millions of barrels of crude oil to be leaked out into the Gulf of Mexico. The extensive oil spill created a lot of pollution and far-reaching effects on the tourism industry. The resultant damage to marine wildlife such as fish will continue to be felt for many years to come. Weeks after the event, and while it was still in progress, the Deep Water Horizon oil spill was being discussed as a disaster that will impact global economies, markets, and mining policies. The potential consequences included structural shifts in energy policy, insurance marketplaces and risk assessment, and financial liabilities to be incurred by BP. The law that affected the operation of BP’s business was the Clean Water Act, which regulates the discharge of pollutants in US’s waters (EPA, 2008). Following the oil spill, regulations have been put in place to regulate oil drilling operations. The Obama administration proposed new regulations on offshore oil and gas drilling. The regulation focused on oil and gas drilling companies to use stronger blowout Preventers that have the capability to close an offshore well in case a drilling breach occurred accidentally.

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.

Metropolitan Edison Company: Victor Stello(nuclear engineer for the plant), Jack Herbein (nuclear engineer for the plant; discussed the issue with the press and basically lied and said that everything was controlled and there was no real danger), Ed Hauser (went into the reactor to check the actual amount of radiation inside of the reactor; result was shocking=100rem/hr, coolant water was not clear and was actually yellow and fizzing with 1250rem), Roger Mattson (another nuclear engineer who butted heads with Victor Stello over how to handle the situation in the plant)

On April 20th 2010 an explosion on an oil ridge of the coast of the Gulf of Mexico, was the cause of the greatest environmental disaster in history of the United States. This explosion took the lives of eleven men who were working on the ridge, and also ruptured an oil line, which dumped more than 4.9 million barrels of oil into the Gulf of Mexico. This oil spill significantly affected the wildlife of the gulf coast, killing hundreds of fishes, birds, and reptile that call the gulf coast home. The spill also affected global supply chain for major industries.

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

At four o’clock in the morning, on March 28th, 1979, reactor two at the Three Mile Island nuclear power plant overheated due to a cooling pipe that was mistakenly closed. After a series of mechanical and human errors, reactor two partially melted down. To release pressure in the chamber radioactive gasses had to be released into the atmosphere. Residents of nearby town Londonderry, Pennsylvania, were not evacuated as they were never exposed to unsafe levels of radiation. It was not for hours after the incident at the power plant had been of concern that the mayor of Londonderry was alerted. Citizens of Londonderry and the nearby areas were unaware of evacuation and contingency

The Exxon Valdez oil spill was the largest oil spill in U.S history. It was a catastrophic disaster that the U.S swore to learn from. Twenty two years later as the prevention procedures became complacent, the Deepwater Horizon explosion made us re-examine our procedures as a nation. The Deepwater Horizon explosion is now the second worst oil spill in the world following the Gulf War Oil Spill in Kuwait in 1991. The U.S used similar techniques to clean the water as the Exxon Valdez clean up, however nothing could have prepared us for 210 million tons of oil and an 80 square mile “kill-zone”. To better understand how a disaster such as an oil spill affects an essentially untouched environment, the Exxon Valdez spill is an almost perfect

“Why I Still Support Nuclear Power, Even After Fukushima” written by William Tucker, nuclear energy is still the best option for the contemporary society we live in today. Tucker goes on to explicate “The events in Japan have confirmed many of the critics’ worst predictions” (Tucker 228). Tucker then examines two other nuclear accidents, Three Mile Island, & Chernobyl. Tucker acknowledges that there is still a very serious threat of contamination that is widespread. Then he gives some facts to show that the other industries have had bad accidents also. In one incident 130 people were killed in a natural gas accident that occurred in Cleveland in 1944, the accident leveled a whole neighborhood. Tucker

The e Deepwater Horizon oil spill at the Macondo well began on April 20, 2010, in the Gulf of Mexico on the BP-operated Macondo Prospect. An explosion on the Deepwater Horizon drilling rig on 20 April 2010 killed 11 people and caused almost 5 million barrels of oil to flow into the Gulf of Mexico. The spill covered 68,000 square miles of land and sea and triggered a response effort involving the use of nearly 2 million gallons of dispersant chemicals (Pallardy). Considered the largest accidental marine oil spill in history, the Deepwater Horizon oil spill (DHOS) resulted in widespread environmental and economic damage, the exact nature of which is only beginning to be understood (Shultz 59). This paper will address the causes of this unmitigated ecological disaster and discuss steps that need to be taken to prevent a similar disaster from occurring again.

Many critics argue that due to the Three Mile Island nuclear incident that occurred March 28, 1979, in Pennsylvania resulted in a reactor meltdown, with no casualties due to a combination of equipment failure and a lack of operators understanding what to do to a faulty reactor. This incident has put the majority public to have safety concerns over not only the operators working in the plants but also the civilians in the surrounding area. Yet since the accident, the United States formed the National Academy for Nuclear Training to improve training the Institute of Nuclear Power Operations which reviews and accredits nuclear utilities’ training programs for all key positions at each plant. In addition, nuclear energy plants have proven the ability to produce clean electricity without greenhouse gas emissions and the reliability due to its increased efficiency and increased power output.

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.
