In 1997, the nations of the G7 agreed to pay to renovate the Shelter, but not for the reasons you think. The Shelter was in such poor condition that it had to be repaired before it could be replaced. Once it was fixed, the Shelter could be covered and safely torn down. That cover – an arch called the New Safe Confinement (NSC) – began construction in 2010 and was finally put into place today. The NSC took nearly seven years and 1.5 billion Euros to complete, and is designed to last 100 years. The arch was constructed alongside the reactor site, then all 36,000 tons of it had to be moved over 300 meters to cover the Shelter. Watch the accompanying timelapse video from the EBRD/Novarka to see the NSC being moved into place.
