IAEA: Chernobyl Shelter Has Lost Containment, Demands Urgent Overhaul

An on-site IAEA team is inspecting Ukraine’s power substations this week to shore up nuclear safety as repeated strikes strain the grid.

Overview

  • The IAEA says Chernobyl’s protective structure lost its primary safety functions after a February drone strike, including its ability to contain radioactive material.
  • Radiation readings remain stable and key supports and monitoring systems are intact, but the agency warns only a timely, comprehensive restoration can ensure long-term safety.
  • The IAEA recommends moisture control, expanded corrosion monitoring, and upgraded automatic surveillance, and it is seeking international backing for the work.
  • EBRD-supported temporary repairs are planned in 2026 to reinforce containment and pave the way for full restoration once conditions allow.
  • Ukraine reported a large overnight barrage of 653 drones and 51 missiles targeting energy assets, while U.S.–Ukraine peace talks in Florida continue as envoy Steve Witkoff says progress depends on Kremlin engagement.
