The Chernobyl site with its monumental arch Pharaonic will be completed next month. Three years after its launch.
Then this building rail will be drawn to cover the reactor No. 4, the one that exploded in 1986. This waterproof cover 110 meters high and 165 long should allow dismantling work.
An arch built by French Bouygues and Vinci, which does not eliminate all risks:
"The exclusion zone is not going to be decontaminated because it will always be storage of nuclear waste here," recalls Vince Novak, director of nuclear safety at the European Bank for Construction and Development (EBRD).
After the disaster, the Russians had hastily constructed a concrete sarcophagus to contain the radiation. It is cracked today. The dome should prevent radioactive leaks for 100 years.
"The ark protect the sarcophagus where there are a lot of toxic nuclear waste, explains Volodymyr Verbytskyi engineer. But it will not be possible to live here before 300 years. "
Once the arch resting on the reactor, it will break the old coffin to collect the contaminated materials. Probably with robots. But according to experts
this could take place in a hundred years only.
"The construction of the structure is going to be completed on time, says our correspondent in Ukraine euronews. The biggest problem that's after. When it will take years in moving radioactive elements found in the reactor 4. At the moment the technical solution still seems far away. "
