Nuclear meltdown. A simulated animation of a core melt in a light-water reactor after a loss-of-coolant accident. After reaching an extremely high temperature, the nuclear fuel and accompanying cladding liquefies and flows to the bottom of the reactor pressure vessel. Three of the reactors at Fukushima I overheated because the cooling systems ...

A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. [ 6 ]
The Chernobyl disaster began on 26 April 1986 with the explosion of the No. 4 reactor of the Chernobyl Nuclear Power Plant near the city of Pripyat in northern Ukraine, near the Belarus border in the Soviet Union. [1] It is one of only two nuclear energy accidents rated at the maximum severity on the International Nuclear Event Scale, the other ...
The Three Mile Island accident was a partial nuclear meltdown of the Unit 2 reactor (TMI-2) of the Three Mile Island Nuclear Generating Station on the Susquehanna River in Londonderry Township, near Harrisburg, Pennsylvania. The reactor accident began at 4:00 a.m. on March 28, 1979, and released radioactive gases and radioactive iodine into the ...
The International Nuclear and Radiological Event Scale (INES) was introduced in 1990 [1] by the International Atomic Energy Agency (IAEA) in order to enable prompt communication of safety significant information in case of nuclear accidents. The scale is intended to be logarithmic, similar to the moment magnitude scale that is used to describe ...
The effects included "metallic taste, erythema, nausea, vomiting, diarrhea, hair loss, deaths of pets, farm and wild animals, and damage to plants." [ 16 ] Some local statistics showed dramatic one-year changes among the most vulnerable: "in Dauphin County, where the Three Mile Island plant is located, the 1979 death rate among infants under ...
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
