On November 29, 2016, the official ceremony of New Safe Confinement (NSC) Arch installing in the design position took place.

To build NSC, 45 donor countries have joined efforts with Ukraine in a specially established fund administrated by EBRD and pledged more than 1.5 billion euros. In total, 10,000 employees from 40 countries, 5,000 of them Ukrainians, were involved in the project.
The ceremonial event was preceded by four years of the Arch structure construction, which was intended to cover Chornobyl Unit 4 destroyed as a result of the accident, and two dramatic weeks of NSC Arch construction sliding on the Shelter object. A huge structure weighing 36.2 thousand tons using the complex jacks system was moved along the special foundations for sliding 327 meters and installed in the design position.
