Globally, there have been at least 99 (civilian and military) recorded nuclear power plant accidents from 1952 to 2009 (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage, the amount the US federal government uses to define nuclear energy accidents that must be reported), totaling US$20.5 billion in property damages.
Fukushima nuclear disaster: 2011 March In 2018, 1 cancer death of a man who worked at the plant at the time of the accident was attributed to radiation exposure by a Japanese government panel. [8] [9] It has been suggested that 2,202 died as a result of the stresses of evacuation. [10] The overall death count as a result of the accident is ...
Large-scale nuclear meltdowns at civilian nuclear power plants include: [13] [62] the Three Mile Island accident in Pennsylvania, United States, in 1979. the Chernobyl disaster at Chernobyl Nuclear Power Plant, Ukraine, USSR, in 1986. the Fukushima Daiichi nuclear disaster following the earthquake and tsunami in Japan, March 2011.
The T-15 (or Tokamak-15) is a Russian (previously Soviet) nuclear fusion research reactor located at the Kurchatov Institute, which is based on the (Soviet-invented) tokamak design. [2] It was the first industrial prototype fusion reactor to use superconducting magnets to control the plasma . [ 3 ]
Erosion of the 150-millimetre-thick (5.9 in) carbon steel reactor head at Davis-Besse Nuclear Power Plant, in Oak Harbor, Ohio, USA, in 2002, caused by a persistent leak of borated water The Hanford Site, in Benton County, Washington, USA, represents two-thirds of America's high-level radioactive waste by volume.
Nuclear aspect: the damage must be related directly to nuclear operations or materials; the event should involve fissile material or a reactor, not merely (for example) having occurred at the site of a nuclear power plant. Primarily civilian: the nuclear operation/material must be principally for non-military purposes.
[13] The term "tokamak" was coined in 1957 [14] by Igor Golovin, a student of academician Igor Kurchatov.It originally sounded like "tokamag" ("токамаг") — an acronym of the words «toroidal chamber magnetic» («тороидальная камера магнитная»), but Natan Yavlinsky, the author of the first toroidal system, proposed replacing "-mag" with "-mak" for euphony. [15]
The Tokaimura nuclear accidents refer to two nuclear related incidents near the village of Tōkai, Ibaraki Prefecture, Japan. The first accident occurred on 11 March 1997, producing an explosion after an experimental batch of solidified nuclear waste caught fire at the Power Reactor and Nuclear Fuel Development Corporation (PNC) radioactive ...
