The Chernobyl Forum predicts an eventual death toll of up to 4,000 among those exposed to the highest radiation levels (200,000 emergency workers, 116,000 evacuees, and 270,000 residents of the most contaminated areas), including around 50 emergency workers who died shortly after the accident, 15 children who died of thyroid cancer, and a ...
The Elephant's Foot is a mass of black corium with many layers, resembling tree bark and glass. It was formed during the Chernobyl disaster of April 1986 from a lava-like mixture of molten core material that had escaped the reactor enclosure, materials from the reactor itself, and structural components of the plant such as concrete and metal.

The largest known amounts of corium were formed during the Chernobyl disaster. [15] The molten mass of reactor core dripped under the reactor vessel and now is solidified in forms of stalactites, stalagmites, and lava flows; the best-known formation is the "Elephant's Foot", located under the bottom of the reactor in a Steam Distribution Corridor.
Nikolai Fomin was the chief engineer of the Chernobyl Nuclear Power Plant at the time of the disaster in 1986. He arrived at the control room of reactor 4 at 4:30 a.m., about three hours after the initial explosion. He ordered the operators to keep pumping water into the reactor core, hoping to cool it down and prevent a meltdown.
The Chernobyl disaster was a catastrophic nuclear disaster that occurred in the early hours of 26 April 1986, at the Chernobyl Nuclear Power Plant in Soviet Ukraine.The accident occurred when Reactor Number 4 exploded and destroyed most of the reactor building, spreading debris and radioactive material across the surrounding area, and over the following days and weeks, most of mainland Europe ...
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.
Vasily Ivanovich Ignatenko (Ukrainian: Василь Іванович Ігнатенко; Belarusian: Васіль Іванавіч Ігнаценка; Russian: Василий Иванович Игнатенко; 13 March 1961 – 13 May 1986) was a Soviet firefighter who was among the first responders to the Chernobyl disaster.
As the RBMK reactor core is very tall (about 7 m (23 ft 0 in)), the cost and difficulty of building a heavy containment structure prevented the building of additional emergency containment structures for pipes on top of the reactor core. In the Chernobyl accident, the pressure rose to levels high enough to blow the top off the reactor, breaking ...
