chernobyl - A huge shell of stainless steel and concrete will Tuesday its final position on the Chernobyl nuclear power plant. The colossus of 165 meters long, 260 meters wide and 110 meters high, looks like a huge airplane hangar large and could easily accommodate the Parisian cathedral Notre Dame. It should occur in the next century that radiation from reactor 4 of the disaster center to escape.
A meltdown of the Chernobyl plant in 1986 caused the biggest nuclear disaster in history. Emergency rate was then made a concrete shell, but that is beginning to show cracks and crumbling. After the disaster event was less than 5 per cent of the radioactivity in the central free; Experts suggest that there are about 200 tons of enriched uranium lies at the crash site.
The casing could not because of radiation directly to be built around the central but is constructed nearby. The Dutch company Mammoet is responsible for the transportation of the 35 000-ton colossus about 330 meters from the construction site for the nuclear power plant. The casing is therefore built on 116 so-called sled shoes, each of which can carry a weight of 703 tonnes and sliding on Teflon job. The sleeve is the largest manmade object that moves over land.
The casing is designed to withstand extreme heat of fire and the cold Ukrainian winter, as well as earthquakes and tornadoes with winds of 330 kilometers per hour.
Inside the envelope is with huge robotic arms, a big drill, a betonverpulveraar and a vacuum of 10 tons of work in the coming decades with the decommissioning of the plant.
The new insulation NPP definitely cost 2.1 billion euros. For which funding was needed foreign aid.\n \n \n advertisement
At the nuclear power plant disaster 600. 000 people were exposed to high radiation. The World Health Organization estimates that 4,000 people therefore are deceased or will die. The same applies to an estimated 5,000 people from the remaining infected areas, where 6.9 million people attended.
