Overview
- An IAEA inspection confirmed the New Safe Confinement has lost its primary safety functions, including the ability to confine radioactive material.
- The assessment found no permanent damage to load‑bearing structures or monitoring systems, and earlier checks reported stable radiation levels with no leaks after the February strike.
- Only limited temporary roof repairs have been completed, and the IAEA urged comprehensive restoration along with humidity control, enhanced corrosion monitoring, and upgrades to the original sarcophagus monitoring system.
- Additional temporary works to restore the shelter’s confinement function are planned in 2026 with support from the European Bank for Reconstruction and Development, with full restoration dependent on security conditions.
- IAEA experts are also evaluating the condition of more than ten electrical substations crucial to nuclear safety, with the mission continuing through December 12.
