The accident raised already heightened concerns about fission reactors worldwide, and while most concern was focused on those of the same unusual design, hundreds of disparate nuclear reactor proposals, including those under construction at Chernobyl, reactors numbers 5 and 6, were eventually cancelled.
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 ...
Initially, the Soviet Union's toll of deaths directly caused by the Chernobyl disaster included only the two Chernobyl Nuclear Power Plant workers killed in the immediate aftermath of the explosion of the plant's reactor. However, by late 1986, Soviet officials updated the official count to 30, reflecting the deaths of 28 additional plant ...
Estimated number of deaths from the Chernobyl nuclear disaster A map showing caesium-137 contamination in the Chornobyl area in 1996. The Chernobyl disaster of 26 April 1986 triggered the release of radioactive contamination into the atmosphere in the form of both particulate and gaseous radioisotopes.
Originally named the Chernobyl Nuclear Power Plant of V. I. Lenin [b], the plant was commissioned in phases with the four reactors entering commercial operation between 1978 and 1984. In 1986, in what became known as the Chernobyl disaster , reactor No. 4 suffered a catastrophic explosion and meltdown; as a result of this, the power plant is ...
The world's first nuclear reactor meltdown was the NRX reactor at Chalk River Laboratories, Ontario, Canada in 1952. [22] The worst nuclear accident to date is the Chernobyl disaster which occurred in 1986 in the Ukrainian SSR, now Ukraine.

Bridge of Death (Pripyat) in Ukraine, a road bridge over a railway line, between the town of Prypiat and the Chernobyl Nuclear Power Plant, where there were unsubstantiated claims of deaths from radiation during the Chernobyl disaster. The explosion destroyed the Chernobyl 4 reactor, killing 30 operators and firemen within three months and ...
