Chernobyl Nuclear Disaster

Chernobyl Nuclear Disaster, (Reuters) – Japan should not expect a repeat of the Chernobyl nuclear disaster after an explosion blew the roof of one of its nuclear plants that had been shaken in a massive earthquake, according to experts on Saturday.

Northern Japan Daiichi reactor 1 of the capital Tokyo began leaking radiation after the 8.9 magnitude earthquake triggered a tsunami and quickly sparked fears of a nuclear disaster.
But experts say the images of mist over the plant suggested that small amounts of radiation were expelled as part of measures to ensure its stability, away from radioactive clouds from Chernobyl who vomits when he exploded in 1986.

“The explosion at the No. 1 generator of nuclear power plant in Fukushima, Japan, which took place today, will not be a repeat of the Chernobyl nuclear disaster,” said Valeriy Hlyhalo, deputy director of the center Chernobyl nuclear safety.

The nuclear emergency in Japan following the massive earthquake disaster recalled 25 years ago at the Chernobyl nuclear power plant in Ukraine, so far the worst nuclear accident in the history of plants.

In the early morning of April 26, a combination of technical and human errors at Chernobyl led to a series of explosions followed by fire and meltdown, releasing huge quantities of deadly radioactive materials in the atmosphere.

The accident occurred during a test of the cooling system of pressurized water plant building Soviet, with unpredictable factors that contribute to a chain reaction of events, beginning with a sudden surge in reactor number four.

Engineers tried to stop the power surge with an emergency stop, but in doing so helped contribute to a further increase in reactor temperature and a number of explosions and fire.

Contrary to the Western nuclear plants, Chernobyl did not containment around the reactor drive, so that in a fire that followed the fallout has been sent into the atmosphere.

Southeast winds carried most of the radioactive particles in neighboring Belarus, but in the weeks that followed, radioactive emissions were also conducted in the East, Western and Northern Europe.

The area around the factory was evacuated in the middle of radioactive contamination and a region of 30 km around the station remains closed to this day. Over 2 million people were evacuated from the area, some, 000 of them permanently.

Once the Soviet government realized the magnitude of the disaster and saw that the envelope open reactor continued to emit radioactive particles into the environment, it has sent soldiers and emergency workers to build common containment around the reactor break provision.

About 1 million workers and 500,000 soldiers were involved in the construction of containment. Although they were sent for only a few minutes at a time, workers were subjected to massive doses of radioactive contamination. Many fell sick and died in subsequent years.

Estimates of the number of victims of the Chernobyl disaster vary. By official accounts, there were direct deaths among the reactor staff and emergency workers.

But the World Health Organization two decades after the accident estimated the death toll at, 000 to, 000. Opponents of nuclear power claim the real figure is over 100,000.
