A huge sarcophagus is being built at the Chernobyl nuclear power plant. When the work is finished in 2015, the great arch structure will be taken to the existing "Shelter" on rails and fixed over it. During the first stage of assembly works about 5000 tons of steel was lifted at the height of twenty two meters (72 ft).
When fully assembled the sarcophagus dimensions are 257 x 164 x 110 meters (843 x 538 x 361 ft). Its total weigh is going to be about 20 000 tons.
