In a stunning feat of engineering, Chernobyl's exploded reactor unit four has now been safely enclosed by the world's largest land-based moving structure. The 36,000-ton New Safe Confinement arch covers the old hastily constructed steel and concrete sarcophagus that was built in 1986 as an emergency measure. The new structure will prevent the escape of still-prevalent deadly radiation over the next century.
Work on the arched structure has been underway in earnest for about 15 years. Because radiation levels immediately above and around the damaged reactor remain extremely high, the massive shelter was assembled on the neighbouring property and carefully pulled into position in a multi-day operation. The European Bank for Reconstruction and Development — which released a dramatic video of the big move — has said that work to environmentally transform Chernobyl is on track for November 2017 completion.
A ceremony to celebrate this major milestone was held on Tuesday. Over 40 countries have donated to the $2.1 billion USD hangar-like project, which is designed to withstand extreme temperatures, corrosion and tornadoes. With the new casement successfully installed, dismantling of the reactor's remains can be safely performed.
A 2,600-square-kilometre exclusion zone was created in northern Ukraine, completely enveloping the workers' town of Pripyat, after the cataclysmic nuclear disaster 30 years ago. The stuck-in-time town and its decayed aesthetic have attracted droves of tourists, who are escorted to and from the area by official tour guides.
