Timelapse shows shield being put over Chernobyl reactor
An explosion in the Chernobyl nuclear power station in 1986 demolished reactor No. 4 and spread radioactive waste across large swathes of Ukraine, Belarus, Russia and other nearby countries.Now, a New Safe Confinement container has begun the process of sliding over the reactor. Once the process is completed, the new structure will enable the eventual dismantling of the aged shelter and radioactive waste. The new container was said to be the largest moveable land-based structure ever built, according to the European Bank for Reconstruction and Development, which oversaw the project. The 354ft-tall arch-shaped structure has a minimum lifespan of 100 years and is made up of 36,000 tonnes of prefabricated metal.
