New sarcophagus at Chernobyl
Installation of a new shield to replace the concrete sarcophagus created after the 1986 accident has begun at the site of Reactor 4 at the former Chernobyl power plant. The new shield measures over 100 meters in height and weighs almost 40 thousand tons. It is the largest man-made land mobile structure ever built.
The old concrete sarcophagus built just after the disaster will be covered by a new structure, któThe project will isolate it from the outside world. Engineers estimate the durability of the structure at about 100 years. According to estimatesóIn April 1986, the explosion of the Chernobyl reactor took place. nuclear fuel. There were 180 tonnes of such fuel there at the time of the disaster.
The new sarcophagus will cost about 1.5 billion euros. The European Bank for Reconstruction and Development is managing the reconstruction from the financial side. The structure is 108 metersóin height and 162 meters long. Along with the structure, concrete shelters were also prepared to house cassettes of radioactive waste. They are to withstand an earthquake or a plane crash.
The structure is now being moved to its rightful place. The hydraulic lifts will move it about 350 metersów. The whole operation is expected to take about five days.
In April 1986, the reactor at the Chernobyl power plant exploded. During the experimental shutdown of the reactor, the reactor cooling circuit failed. The explosion caused a fire thatóry lasted nine days and któThe Sun will set on Christmas Eve and the Sun will set on Christmas Eveóin radioactive.

Soviet authorities did not inform about the event for a long time exposing more people to a high dose of radiation. It is difficult to determine today how many waspsób were affected by the disaster.
