THE WORST NUCLEAR DISASTER,THE CHERNOBYL DISASTER OF 1986..

The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine which was under the direct jurisdiction
of the central authorities in Moscow.

An explosion and fire released large
quantities of radioactive
contamination into the atmosphere,
which spread over much of Western USSR and Europe.

It is widely
considered to have been the worst nuclear power plant accident in history, and is one of only two
classified as a level 7 event on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster).

The battle to contain the contamination and avert a
greater catastrophe ultimately
involved over 500,000 workers and
cost an estimated 18 billion rubles, crippling the Soviet economy.

The disaster began during a systems
test on Saturday, 26 April 1986 at
reactor number four of the Chernobyl
plant, which is near the city of Prypiat.

There was a sudden power output surge, and when an
emergency shutdown was attempted,
a more extreme spike in power output
occurred, which led to a reactor vessel
rupture and a series of explosions.

These events exposed the graphite moderator of the reactor to air, causing it to ignite.

The resulting fire sent a plume of highly radioactive
smoke fallout into the atmosphere and over an extensive geographical area,
including Pripyat. The plume drifted
over large parts of the western Soviet Union and Europe.

From 1986 to 2000, 350,400 people were
evacuated and resettled from the most
severely contaminated areas of Belarus, Russia, and Ukraine.

The accident raised concerns about
the safety of the Soviet nuclear power industry, as well as nuclear power in
general..
Well,excessive pushing for forceful growth is
always a double sided sword,isnt it...?
