The Three Mile Island Meltdown

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

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)

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.

This caused reactors 1 through 3 to go into a meltdown and it created a situation where Japan was on the brink of a major environmental disaster. To fully understand the different events there will be a focus on: factors that caused the meltdown, why this did not impact the other three reactors, the consequences, who is responsible and how these incidents can be prevented in the future. Together, these elements will highlight the underlying effects of this disaster and its impact on the region. ("Fukushima Accident")

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 disaster took place on April 1986, and was caused by inexperienced staff. When the power plant had to undergo a special test, to make sure that sufficient amount of cooling water would be supplied to the reactor in case of a power outage. However, the test had been delayed, because the national grid required the power output more than the expected time. Hence, the test was postponed after midnight where the night shift had to come. The night shift had little experience about such a test as most of them were electrical engineers rather than nuclear. On the other hand, the night shift had to perform the test before the grid needed the power again, otherwise they would have all been fined or fired. Consequently, lead to an unnecessary pressure on the personnel, which in turn increased the probability of making incorrect

That accident was at urban centre in 1986. consistent with the report two-handed down in 2000 by the global organisation X c. Committee on the consequences of Atomic Radiation, twenty eight employees died within the initial 3 months when the incident, nineteen died between 1987 and 2004 of varied causes not essentially related to radiation

The Chernobyl accident was a disastrous nuclear event that happened on 26th April 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The Chernobyl disaster is classified as a level 7 event according to the International Nuclear Event Scale (only two events have been classified this high in the past) and has caused damages that consist of the cost of 500,000 workers and 18 billion rubles, 31 deaths according to the Soviet casualty count (this is still being disputed) and between 4000-27000 affected future deaths due to radiation exposure [G1].

Located next to the small town of Pripyat, in the Ukraine, stands the Chernobyl Nuclear Power Plant. During the morning hours on April 26, 1986, operators within Reactor Four of the nuclear plant began a test to determine how long turbines would spin to supply power to the main pumps following a loss of electrical power. Operators gradually began decreasing the power of Reactor Four. The reactor became unstable, continuing to decrease in power on its own. In an effort to prevent the reactor from completely shutting down, operators withdrew a large percentage of the control rods, allowing power to rise. Afraid the automatic shutdown systems would SCRAM, or instantly shut down the reactor, operators disengaged the emergency shutdown systems. It was then that an uncontrollable power surge, causing an increase in heat, led Reactor Four to spike beyond its full operating power. Plant operators made an

Three Mile Island Nuclear Power Station is on an island that is located about 10 miles from the town of Harrisburg, Pennsylvania.The plant housed two nuclear reactors, Unit 1 and Unit 2.Now there is only one that

Daniel Torres 8B Language Arts April 12, 2016 Chernobyl Tragedy Going from a peaceful and lovely town to a disastrous ghost town with scary mutations. The chernobyl disaster was just a reminder of how horrible consequences nuclear power can have. 26 of April 1986, in the Chernobyl Nuclear Power Plant near the city of Pripyat the tragedy started and many people died. This disaster was the worst nuclear power plant disaster ever in human history in terms of casualties.

Countless nuclear power plant accidents have been occurring quite frequently since its invention. Some accidents have even been underestimated,

On 11 March 2011 in Japan, the Fukushima nuclear power plant was seriously damaged by an earthquake and the radioactive substances were leaked to the surrounding. Local people had to evacuate away and up till now they are living under threat.

During the 1970s, Americans were brought together after the death of the King of Rock and Roll and the release of the one of the greatest movies, Star Wars, but a historical disaster was yet to come. On March 28,1979, located on the Susquehanna River, in the state of Pennsylvania, one of the worst nuclear accidents occurred. One of the two water reactors had failed to close, allowing cooling water containing radiation to seep out. Although there were no reported injuries or deaths, several safety precautions were taken in many other areas of nuclear plants.

The earthquake made the nuclear leak, and the nuclear leak not only affected the human activities, but also affected the environment as well. The nuclear radiation affects the soil and the sea around the station. Many fish died and the sea was polluted.
