The Chernobyl disaster began on 26 April 1986 with the explosion of the No. 4 reactor of the Chernobyl Nuclear Power Plant ... some big, some small enough to pick ...
Chernobyl disaster, 26 April 1986. Unsafe conditions during a test procedure resulted in a powerful steam explosion and fire that released a significant fraction of core material into the environment, resulting in an eventual death toll of 4,000–27,000.
The Elephant's Foot is the nickname given to the large mass of corium, composed of materials formed from molten concrete, sand, steel, uranium, and zirconium.The mass formed beneath Reactor 4 of the Chernobyl Nuclear Power Plant, near Pripyat, Ukraine, during the Chernobyl disaster of 26 April 1986, and is noted for its extreme radioactivity.
The Chernobyl Nuclear Power Plant [a] (ChNPP) is a nuclear power plant undergoing decommissioning.ChNPP is located near the abandoned city of Pripyat in northern Ukraine, 16.5 kilometres (10 mi) northwest of the city of Chernobyl, 16 kilometres (10 mi) from the Belarus–Ukraine border, and about 100 kilometres (62 mi) north of Kyiv.
Chernobyl was chosen as the site of Ukraine's first nuclear power plant in 1972, located 15 kilometres (9 mi) north of the city, which opened in 1977. Chernobyl was evacuated on 5 May 1986, nine days after a catastrophic nuclear disaster at the plant, which was the largest nuclear
The Abstract of the April 2006 International Agency for Research on Cancer report Estimates of the cancer burden in Europe from radioactive fallout from the Chernobyl accident stated "It is unlikely that the cancer burden from the largest radiological accident to date could be detected by monitoring national cancer statistics. Indeed, results ...
The Exclusion Zone was established on 2 May 1986 () soon after the Chernobyl disaster, when a Soviet government commission headed by Nikolai Ryzhkov [8]: 4 decided on a "rather arbitrary" [6]: 161 area of a 30-kilometre (19 mi) radius from Reactor 4 as the designated evacuation area. The 30 km Zone was initially divided into three subzones: the ...
This was followed by a steam explosion that exposed the fuel, a raging fire, and a core meltdown. The fire lasted for days to weeks, and there is controversy over whether it was the fuel burning, nuclear decay heating or whether the graphite moderator that made up most of the core was involved. See Chernobyl Disaster, Note 1, for more discussion.
