"In the middle of a vast exclusion zone in northern Ukraine, the world's largest land-based moving structure has been built to prevent deadly radiation spewing from the Chernobyl nuclear disaster site for the next 100 years.

On April 26, 1986, a botched test at the Soviet nuclear plant sent clouds of smouldering nuclear material across large swathes of Europe, forced over 50,000 people to evacuate and poisoned unknown numbers of workers involved in its clean-up.

A concrete sarcophagus was hastily built over the site of the stricken reactor to contain the worst of the radiation, but a more permanent solution has been in the works since late 2010."
