Since 2008, we contribute to the creation of the new arched containment!


Novarka is a European Building and Public Works consortium led by the French companies Vinci and Bouygues.
The consortium is designing and building the new sarcophagus to cover the former reactor 4 of the Chernobyl nuclear plant destroyed in the 1986 disaster. The new structure will also cover the first sarcophagus made of steel-clad concrete and filled with 300,000 metric tons of sand, clay, lead and boron, which deteriorated very quickly.
This new arched confinement enclosure is made of an 18,000-metric ton metal frame, measuring 105 m in length with a width of 257 m. Supported by two concrete sleepers, the arch is assembled to the west of the reactor and will be slid over the top of the existing sarcophagus. Construction is was completed in 2017.

The primary goal of the enclosure is to confine radioactive matter and protect the existing object shelter against climate damage. Eventually, the enclosure will make it possible to carry out the dismantling operations for unit 4 at the Chernobyl plant.
IOTA Group has been involved in the NOVARKA project since 2008, managing the international mobility of consultants.
We also assist consultants with recruitment and technical support.

Currently, we have about forty IOTA team members on site.
