Ukraine's Ecology Ministry publishes video of giant arch sliding into its place
A massive, arch-shaped shield, called the New Safe Confinement (NSC), began sliding into its place to cover the site of the world's worst nuclear accident.
Ukraine's Ecology Ministry has published a video showing how the arch is moving to seal off Chornobyl's reactor Unit 4.
When the new shield is in place, work can begin to dismantle the concrete Soviet sarcophagus, hastily built some 30 years ago.
The arch, which is 275 meters wide by 108 meters tall, is being moved into place by a system of hydraulic jacks.
The European Bank for Reconstruction and Development (EBRD), which is financing the project, describes the arch as the largest moveable land-based structure ever built. The new cover cost about EUR 1.5 billion to construct.
