IAEA Says Chernobyl’s Shelter Has Lost Confinement Function After Drone Strike

IAEA inspectors say the damaged arch no longer provides confinement, requiring urgent repairs.

Overview

  • The IAEA’s December assessment found the New Safe Confinement has lost primary safety functions, including its ability to contain radioactive material.
  • Only limited temporary fixes have been carried out since a February drone strike damaged the structure, the agency reported.
  • Inspectors said the main load‑bearing elements and monitoring systems remain in place, providing a basis for restoration work.
  • The IAEA called for specific technical upgrades, including improved humidity control, advanced corrosion monitoring, and an automated system to manage the reactor remains.
  • Additional temporary repairs supported by the EBRD are planned for 2026, with a permanent IAEA team on site as conflict‑related damage to regional substations complicates safety operations.
