Initially Mayak was dumping high-level radioactive waste into a nearby river, which flowed to the river Ob, flowing farther down to the Arctic Ocean. The Kyshtym disaster was a radiation contamination disaster on 29 September 1957, in Mayak, a nuclear plant in Russia (then a part of the Soviet Union).It measured as a Level 6 disaster on the International Nuclear Event Scale (the Chernobyl disaster and the Fukushima disaster are the only accidents listed as more serious than this one). The disaster released more radioactive contamination than the 1986 Chernobyl disaster and further contaminated the already heavily polluted area. Estimated 200 possible cancer fatalities: 6 October 10, 1957: Sellafield aka Windscale fire, Cumberland, United Kingdom A second reactor on the site is also shut down and the site decontaminated. Timelines help us to place films in their historical setting and to observe how films are related to social, political and technological contexts. This paper presents an overview of the nuclear accident that occurred at the Mayak Production Association (PA) in the Russian Federation on 29 September 1957, often referred to as 'Kyshtym Accident', when 20 MCi (740 PBq) of radionuclides were released by a chemical explosion in a radioactive waste storage tank. The disaster shot a plume of highly radioactive materials into the atmosphere and made it necessary to evacuate nearly 340,000 people from the surrounding regions. ... > Kyshtym accident 1957. Despite the classification, the incident is said to be much less severe than Chernobyl, and officials insist there is only a minimal risk to public health. Next Post: Kyshtym Nuclear Power Plant Disaster.

And, there's not even basic containment going on at Fukishima. The Chernobyl tragedy: Beginning. More recent epidemiological studies suggest that around 49 to 55 cancer deaths among riverside residents can be associated to radiation exposure. Because of the high level of radioactivity, the waste was heating itself through decay heat (though a chain reaction was not possible). Make educational timelines or create a timeline for your company website. A powerful tsunami generated by a magnitude-9.0 earthquake out at sea slams into the Fukushima Daiichi nuclear power plant, damaging four of six reactors at the site.

Kyshtym Nuclear Disaster Occurs In Secret On September 29, a hastily stored tank of nuclear waste exploded in the Russian town Ozyorsk, the original site of the Soviet nuclear weapons program. Originally classified as INES Level 5, the severity was raised to INES Level 7 on 12 April 2011 when a new estimate suggested higher levels of radiation than previously thought had leaked from the plant. [23] The Soviet government in 1968 disguised the EURT area by creating the East Ural Nature Reserve, which prohibited any unauthorised access to the affected area. But very few are aware of what happened at Kyshtym in 1957 due to the fact that the horrific nuclear disaster that occured there was covered up by the Soviet Union for years, and facts about what happened there were never released to the world until the Soviet Union collapsed in the early 1990's. [26][27] The incident has been speculated as partially inspiring the Russian science fiction novel Roadside Picnic. The second was at full capacity when two malfunctions occurred: first there was a release of radioactive water, then radioactive gas was detected on the perimeter. A tank at a uranium and plutonium factory inside the plant explodes, resulting in radioactivity being dispersed into the atmosphere contaminating an area of over 120 sq km (INES Level 4). A storage facility for liquid nuclear waste was added around 1953. The Kyshtym disaster is not the only reason that Chelyabinsk is so contaminated. The chemical explosion produced an aerosol plume that attained an altitude of some 1000 meters and resulted in wide ranging dispersal of ejected radioactive material. Mayak, a major plutonium-producing site in Russia, was also the site of one of the worst nuclear disasters of all time.

Nuclear power plant accidents: Number three reactor of the Fukushima nuclear plant is seen burning after a blast following an earthquake and tsunami Photograph: Ho/DigitalGlobe [18] Medvedev's description of the disaster in the New Scientist was initially derided by Western nuclear industry sources, but the core of his story was soon confirmed by Professor Lev Tumerman, former head of the Biophysics Laboratory at the Engelhardt Institute of Molecular Biology in Moscow. On September 29th of 1957, the cooling system for one of the waste storage tanks failed, causing evaporation of the tank's cooling liquid and combustion of the tank's 70 to 80 tons of radioactive waste. After World War II, the Soviet Union lagged behind the United States in the development of nuclear weapons, so it started a rapid research and development program to produce a sufficient amount of weapons-grade uranium and plutonium. Timetoast's free timeline maker lets you create timelines online. [20] This would include the effects of all radioactive releases into the river, 98% of which happened long before the 1957 accident, but it would not include the effects of the airborne plume that was carried north-east.
