The story of how a massive arched shelter was slid into place over the Chernobyl nuclear disaster site in Ukraine. The inside story of a unique engineering feat at the site of the world's worst nuclear disaster, as technicians move an enormous roof over the still irradiated remains of the plant's No 4 reactor.
