Major step in unique engineering project as Chernobyl arch slides into place

One of the most ambitious projects in the history of engineering passes a major milestone today as the arch shielding radioactive waste caused by the 1986 Chernobyl nuclear power station accident has started sliding into place. Chernobyl’s New Safe Confinement (NSC) is the largest moveable land-based structure ever built, with a span of 257 metres, a length of 162 metres, a height of 108 metres and a total weight of 36,000 tonnes equipped.
