The installation of the confinement arch for the damaged Chernobyl reactor is a milestone in the work to ensure the safe management of the site.
The scale of this 25,000-ton structure, which is 108 meters high and 162 meters long, is unprecedented; it was built by Bouygues and Vinci, which are part of the Novarka consortium.
Work will need to continue until the end of 2017 in order to make the structure operational so that the old containment structure can be dismantled and the site can be decontaminated.
The work at the Chernobyl site is financed by international funds established on the initiative of the G7 and managed by the EBRD. France is the second largest donor, with a contribution of €178 million.
