Russia’s state nuclear construction company Atomstroyexport has finished concreting the outer containment dome for the Kursk 2-1 nuclear power unit under construction in western Russia.
Atomstroyexport said the move marks the final stage of building the containment structure, which protects the reactor systems from “external influences”.
The company said the outer containment took 206 days to complete with the dome requiring about 4,000 cubic metres of concrete alone.
