Chernobyl Nuclear Power Plant sarcophagus

The containment structure consists of an arched metal shell that rests on massive concrete foundations and completely encloses the damaged reactor block. The construction features a rail system that allows maintenance work, along with systems to monitor and control conditions inside.

After the accident in 1986, a first cover was built in less than seven months to stop the immediate release of radiation. The current shell was slid over the old construction in 2016 and is designed to provide protection for at least a century.

Scientists from different countries work inside today, monitoring radiation levels and conducting research that provides long-term insights into nuclear safety. This international cooperation is visible in the daily work of teams who collaborate on one of the biggest technical challenges of our time.

Visitors can view the exterior from a safe distance, while guided tours through the zone offer explanations about the technical details and safety measures. Access to the site requires special permits and compliance with strict radiation protection protocols.

The shell moves on special rails and was first assembled next to the old sarcophagus before being pushed into its final position using hydraulic systems. This construction method allowed workers to significantly reduce exposure to radiation during the building process.
