The structure, which is estimated at EUR 1.5 billion, weighs 36,000 tonnes, it's the largest of this kind in the world.
The arch is designed to create a leak-tight barrier to contain radioactive substances for at least the next 100 years.
It was developed by Joint Venture NOVARKA. On November 14, the company started the process of the installation of the arch.
NOVARKA, a 50/50 joint venture formed by VINCI CONSTRUCTION and BOUYGUES TRAVAUX PUBLICS, is currently building the New Safe Confinement over the Unit 4 reactor in Chornobyl, which exploded on April 26, 1986.
