On some levels, the accident that became known as TMI Three Mile Island was a wake-up call and an expensive learning opportunity for both the nuclear industry and the society it was attempting to serve.

A B Stratofortress carrying two Mark 39 nuclear bombs broke up in mid-air, dropping its nuclear payload in the process.

A brief history of the Three Mile Island nuclear plant known for reactor accident - ABC News

Eight fatalities and more than 30 people were over-exposed to radiation. The crisis is generally regarded as the moment in which the Cold War came closest to turning into a nuclear conflict [60] and is also the first documented instance of mutual assured destruction MAD being discussed as a determining factor in a major international arms agreement.

Wood River Junction criticality accident. Resulted in 1 fatality The KC was completely destroyed when its fuel load ignited, killing all four crew members. The BG broke apart, killing three of the seven crew members aboard. The non-nuclear explosives in two of the weapons detonated upon impact with the ground, resulting in the contamination of a 2-square-kilometer acre 0.

The aircraft was carrying four hydrogen bombs when a cabin fire forced the crew to abandon the aircraft. Six crew members ejected safely, but one who did not have an ejection seat was killed while trying to bail out.

The bomber crashed onto sea ice in Greenlandcausing the nuclear payload to rupture and disperse, which resulted in widespread radioactive contamination. Soviet submarine K reactor near meltdown.

On August 27, an uncontrolled increase of the reactor's power occurred following work to upgrade the vessel. One of the reactors started up automatically when the control rods were raised to a higher position.

Power increased to 18 times its normal amount, while pressure and temperature levels in the reactor increased to four times the normal amount. The automatic start-up of the reactor was caused by the incorrect installation of the control rod electrical cables and by operator error.

Radiation levels aboard the vessel deteriorated.

The China Syndrome

Plutonium solution was poured into a cylindrical container with dangerous geometry. One person died, another took a high dose of radiation and radiation sickness, after which he had two legs and his right arm amputated.

Lucens reactor in Switzerland undergoes partial core meltdown leading to massive radioactive contamination of a cavern. Columbus radiotherapy accident, 10 fatalities, 88 injuries from cobalt source. Anatoli Bugorski was working on Uthe largest Soviet particle acceleratorwhen he accidentally exposed his head directly to the proton beam.

He survived, despite suffering some long-term damage. Over 1, tons of radioactive mill waste and millions of gallons of mine effluent flowed into the Puerco Riverand contaminants traveled downstream. Ina small capsule containing highly radioactive caesium was found inside the concrete wall of an apartment building.

The accident was detected only after the residents called in a health physicist.

The chain of events during the Three Mile Island accident

Houston radiotherapy accident, 7 fatalities. Radiation accident in Moroccoeight fatalities from overexposure to radiation from a lost iridium source. Fernald Feed Materials Production Center gained notoriety when it was learned that the plant was releasing millions of pounds of uranium dust into the atmosphere, causing major radioactive contamination of the surrounding areas.

That same year, employee Dave Bocks, a year-old pipefitter, disappeared during the facility's graveyard shift and was later reported missing.

Eventually, his remains were discovered inside a uranium processing furnace located in Plant 6. Soviet submarine K accident. Ten fatalities and 49 other people suffered radiation injuries. Soviet submarine K reactor almost had a meltdown.

Sergei Preminin died after he manually lowered the control rods, and stopped the explosion. The submarine sank three days later.Jun 21,  · Plant Diagram; The Three Mile Island Unit 2 reactor, near Middletown, Pa., partially melted down on March 28, 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.

Mar 28,  · Watch video · Three Mile Island is the site of a nuclear power plant in south central Pennsylvania. In March , a series of mechanical and human errors at the plant caused the worst commercial nuclear. The Three Mile Island accident occurred on March 28, , in reactor number 2 of Three Mile Island Nuclear Generating Station (TMI-2) in Dauphin County, Pennsylvania, near Harrisburg.

It was the most significant accident in U.S. commercial nuclear power plant history. [2]Location: Four Mile Island, Dauphin County, Pennsylvania. The most serious of these was the Three Mile Island accident in Davis-Besse Nuclear Power Plant has been the source of two of the top five most dangerous nuclear incidents in the United States since Relatively few accidents have involved fatalities.

During this period of heightened discussion about the future of nuclear power, it has been tempting to draw parallels with the Three Mile Island accident in the United States. As with Fukushima, Three Mile Island instigated a major public conversation about nuclear safety. Three Mile Island, the Pennsylvania nuclear power plant that was the site of the worst commercial nuclear power accident in the United States 38 years ago, will close in unless it receives a state bailout, parent company Exelon Corp.
