"Next to a crumbling nuclear reactor destroyed in an explosion 30 years ago, an unprecedented project in the history of modern engineering is being built. When it’s completed, the New Safe Confinement, or NSC, will be the largest movable object built on land, according to the European Bank for Reconstruction and Development, or EBRD. When an explosion tore through Chernobyl’s No. 4 reactor on April 26, 1986, near Pripyat, Ukraine, more than 30 people died and countless others have died from radiation symptoms since, according to the International Atomic Energy Agency and the World Health Organization. The Ukraine government evacuated some 135,000 people from the area and the 19-mile exclusion zone around the plant will re-main uninhabitable for decades."
