The In the Soviet, The Chernobyl nuclear power plant

The world’s most awful civilian nuclear accident took place when a reactor
exploded at the Chernobyl power plant situated in Ukraine which was a part of
The Soviet Union back then. Today’s Byelorussian received 60% of the initial
radioactive wave .This radioactive cloud spread across most of the Europe. In the
Soviet, The Chernobyl nuclear power plant was considered the most advanced
facility of its time. On April 26th 1986, technicians prepared to
check the standby cooling system in the fourth reactor but this regular checkup
went extremely disastrous. A nuclear reactor is like a giant steam engine. A
massive amount of heat energy is created by the reaction of the uranium fuel
rods which is used to run huge turbines to generate electricity. To slow down the
reaction, control rods are inserted in between the uranium and it’s important
that the cooling water is pumped around the core to prevent any excessive heating
but as the test began almost all of the control rods were removed and the technicians
lost the control of the flow of coolants, and as the temperature rose
ridiculously it melted away the core. At 1:23 A.M. the fourth reactor exploded,
shooting 8 tons of radioactive debris into the air. 115, 000 people were
evacuated who were within 30
km radius from the nuclear plants. It took about 2 weeks,
15 days to be exact, to extinguish the fires inside. More than 50,000 civilian
and military personnel were recruited to deal with the accident and its aftereffects.
Within a few days 31 firefighters and plants workers were killed due to acute
exposure to radiation. The radioactive cloud was as toxic as 400 Hiroshima
atomic bomb explosions. The plant workers quickly built a concrete Sarcophagus
to enclose the entire reactor to prevent more spreading of radiation. Inside there
remain 200 tons of radioactive fuel. The plant still did not stop operating; in
fact the other three reactors were used to overcome power shortages in the
Ukraine. It wasn’t until the year 2000 that the Chernobyl Plant was completely
closed down. With the concrete sarcophagus disintegrating, the international
community began to build a new confinement structure for the fourth reactor. It
is 110 meters
tall, which is higher than the statue of liberty and with a width large enough
to fit a ship the size of a titanic. The cost of construction is projected to
be 3 Billion dollars. Construction is scheduled for completion in 2017. The massive
steel dome will slide over reactor number four. The confinement structure is
expected to last for at least 100 years.
