Transcript of Chernobyl Nuclear Disaster

A group of operators were experimenting in order to find out how long the turbines could continue to produce sufficient energy if they cut the power plant.

Chernobyl didn't have the computers which will shut the reactor down automatically if something goes wrong.
The causes of the Chernobyl Nuclear Disaster
The effects of the Chernobyl Nuclear disaster.
Basic information about the Chernobyl Nuclear Disaster.
The Chernobyl Nuclear Disaster took place on the 26th of April 1986.

The Chernobyl Nuclear Disaster took place at Pripyat, Ukraine.

The Chernobyl Nuclear Disaster is one of only two level 7 incidents on the International Nuclear Event Scale.
The responses to the Chernobyl Nuclear Disaster
135,000 people were evacuated between the 27th April ans 31st May 1986.
35,000 firemen tried to find it.
3 scientists dove into a radioactive pool to remove a valve. they all died bu prevented an explosion far greater.
Benefits are still being paid to 7 million people affected by the Chernobyl Nuclear disaster.
Chernobyl Nuclear Disaster
Animals like Wolves mutated, while others died.
800,000 people suffered radiation exposure, causing 56 direct deaths.
The radiation made a fireman's eye to change from brown to blue.
There are expected to be 100,000 fatal cancer victims.
Fishermen were unable to sell fish and earn money because the fish were contaminated.

Chernobyl Today
The region today is widely known as one of the world's most unique wildlife sanctuaries. Thriving populations of wolves, deer, lynx, beaver, eagles, boar, elk, bears and other animals have been documented in the dense woodlands that now surround the silent plant. Only a handful of radiation effects, such as stunted trees growing in the zone of highest radiation and animals with high levels of cesium-137 in their bodies, are known to occur.

But that's not to suggest that the area has returned to normal, or will at any point in the near future. Because of the long-lived radiation in the region surrounding the former Chernobyl Nuclear Power Plant, the area won't be safe for human habitation for at least 20,000 years.
Additional facts about the Chernobyl Nuclear Disaster
It is one of only two Level 7 incident on the International Nuclear Event Scale.
Belarus received 70% of the contamination from Chernobyl.
Nuclear rain from the Chernobyl disaster fell as far away as Ireland.
Benefits are still being paid to 7 million people affected by the Chernobyl disaster.
Around 97% of the radioactive material from the Chernobyl plant remains in a crumbling sarcophagus (coffin).
Basic Information about Nuclear Energy
Nuclear energy works in a similar way to fossil fuels burning stations except it is a chain reaction inside a reactor that makes the heat instead. the reactor uses Uranium rods as fuel, and heat is generated by nuclear fission. neutrons smash into the nucleus of the Uranium atoms, which split roughly in half and release energy in the form of heat. Carbon dioxide gas is pumped through the reactor to take the heat away, and the hot gas heats water to make steam. the steam turns the turbines which turn the generators. Modern nuclear power stations use the same type of turbines and generators as conventional power stations.

Although nuclear energy produces a lot of energy from little fuel and doesn't contribute to the greenhouse effect, it can be dangerous because the small amount of waste it produces has to be sealed and buried for many years to allow the radio activity to die away, otherwise the radiation could kill everyone.
The three very brave people.
By the sixth day, when the Soviet authorities required three men to step forward, all were aware of the risk. According to Grigori Medvedev, author of The Truth About Chernobyl, a group of soldiers were briefed on the stakes if the valves were not turned, the water not drained. There was also a degree of bribery. While they were unlikely to survive, their families would be richly rewarded...Three men volunteered: Alexei Ananenko, an engineer who knew the location of the valves, and two soldiers, Valeri Bezpalov and Boris Baranov. The trio suited up and entered the radioactive waters of the flooded chamber. All three returned to the surface suffering severe radiation poisoning, but were pleased to see their colleagues jump with joy at the news that the valves were now open. Over the next day 20,000 tonnes of radioactive water was pumped out, and a subsequent report revealed that had this not been done, a thermal explosion would have taken place. The men's reward, like those others who died at Chernobyl, was to be buried in lead coffins, the lids soldered shut.but if you think about it... the fact that they are highly radioactive does mean that bacteria and parasites wont be able to survive inside the box... meaning that the three bodys would be momafide for millions of years... if you want to think it in some positive
