The International Atomic Energy Agency (IAEA) inspection has determined that the protective arch of the Chernobyl Nuclear Power Plant no longer performs its key function of radiation protection.

Following an assessment, it was found that after a drone attack by Russia in February 2025, the metal structure of the sarcophagus over the fourth reactor sustained significant damage. This has led to the loss of its primary role – containing radioactive materials and preventing their release into the environment.
IAEA Conclusions on the Damage
IAEA Director General Rafael Grossi reported that the agency’s expert group confirmed the loss of key safety functions of the structure. However, no irreversible damage was recorded in the load-bearing elements of the building or in the monitoring systems that control radiation levels.
“It has been confirmed that the protective structure has lost its essential safety functions, including containment capability, but it was also found that no permanent damage was done to its load-bearing structures or monitoring systems.”
The Need for Comprehensive Restoration
According to Rafael Grossi, certain repair measures have already been carried out at the Chernobyl Nuclear Power Plant. At the same time, he emphasized that to prevent further deterioration and ensure long-term nuclear safety, a comprehensive restoration of the protective arch is necessary. The IAEA stresses the importance of such actions for maintaining environmental safety at the site and throughout the region.
