This paper will address how the Fukushima Nuclear Power plant violated the following NSPE Canons of Engineering Ethics: holding the paramount of safety, health, and welfare of the public, and avoiding deceptive acts. The misjudgment and underperformance by the engineers during the 2011 Tohoku Earthquake caused a large uproar of

The Three Mile Island Accident When someone thinks of problems plaguing the world, nuclear energy is not the first thing that comes to peoples minds these days.[1]Nuclear power was once deemed the new energy of the future.[2]However, numerous nuclear power plant accidents around the world put a damper on that notion.The United States considers itself one of the most technologically advanced countries in the world, but 103 nuclear reactors currently operating within her borders, one was bound to fail sometime or another.[3]

There have been lots of nuclear accident around the world. One of the accident that had a major impact on the world was the Chernobyl disaster. The disaster took place on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The disaster was caused by a reaction explosion induced by design faults and staff application errors. The accident took place in the course of scheduled tests to check the power supply mode in the event of external sources loss. Even after 10 days, explosions and ejections of radioactive substances continued. The release of radiation and radioactive substance polluted the places within 30 km of Chernobyl, and those areas have been closed for a long period of

Three Mile Island Three Mile Island is a nuclear power plant, and nuclear energy is energy in the nucleus (core) of an atom. They use nuclear energy to provide electricity for the U.S. Nuclear energy can be good and it also could be bad ways that it can be

Summary The Fukushima disaster was caused by an earthquake and its following tsunami which caused a failure in the backup systems (World Nuclear Association, 2016). The tsunami knocked out the generators that powered the cooldown processes for three of the Fukushima power plants which caused the radiation leaks and other complications. Consequentially, the disaster was initially classified as a level 5 on the INES scale. Further investigation after the disaster was under control changed it to a level 7 disaster, the highest level on the INES scale. The estimated radioactive releases were about one tenth of Chernobyl, the worst nuclear disaster in history.

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

Three Mile Island 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.

Sl-1: America's First Nuclear Disaster Describe the Incident and Identify Toxic Materials On January 3, 1961 at 9:01 PM the United States experienced what any believe the be the first nuclear reactor accident in world history (Adams, 1996). The US Army had commissioned a small reactor prototype to be built in the Idaho desert that surround Idaho Falls. They believed that they were isolated enough that they could conduct experiments with a small reactor that would mimic the conditions of the site they wished to have the reactor on while also allowing for a safety zone for the people in the nearby town. The reactor was a small three rod affair that did not have the shielding or the safety measures that would come in response to this accident (Stacy, 2000, 144).

The nuclear disaster in Fukushima occurred at fourteen forty six, Japanese time. The disaster occurred because a major magnitude nine earthquake struck North Eastern Japan and a fifteen meter high tsunami also struck the power plant (Grimston). There were eleven overall reactors that were effected by the earthquake and tsunami. Nine of the reactors cooling systems continued to work after the natural disasters occurred, but reactors one, two and three of the Fukushima Daiichi plant were terribly damaged and could not cool down the fission process. This is what lead to the one, two and three reactors to melt, causing the most detrimental damage to the global community (Grimston). Critics of the disasters say that Daiichi was not up to global nuclear safety standards because the wall the protected the plant was only stable against six meter tall tsunami waves, not the massive

Each year, enormous quantities of radioactive waste are created during the nuclear fuel process, including 2,000 metric tons of high-level radioactive waste and 12 million cubic feet of low-level radioactive waste in the U.S. alone. More than 58,000 metric tons of highly radioactive spent fuel already has accumulated at reactor sites around the U.S. for which there currently is no permanent repository. Even if Yucca Mountain is licensed, the Department of Energy has stated that it would not open before 2017. In 1979, the United States had its own disaster following an accident at the Three Mile Island Nuclear Reactor in Pennsylvania.In avoiding such accidents the industry has been very successful. In over 16,000 cumulative reactor years of

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.

     Three Mile Island was a three month old nuclear power plant located in southeast Pennsylvania. On March 28, 1979, a series of mechanical and human errors led to above-normal levels of radioactive gas being released

On March 11, 2011, Fukushima, Japan; a nuclear powered town, 250 km from Tokyo, was struck with two natural disasters. These further led to three nuclear reactors emptying highly radioactive substances.

The Effects of the Chernobyl Accident on International Actions Concerning Nuclear Power Early in the morning of April 27, 1986, the world experienced its largest nuclear disaster ever (Gould 40). While violating safety protocol during a test, Reactor 4 at the Chernobyl power plant was placed in a severely unstable state, and in a matter of seconds the reactor output shot up to 120 times the rated output (Flavin 8). The resulting steam explosion tossed aside the reactor’s 1,000 ton concrete covering and released radioactive particles up to one and a half miles into the sky (Gould 38). The explosion and resulting fires caused 31 immediate deaths and over a thousand injuries, including radiation poisoning (Flavin 5). After the
