A containment structure encasing the Chernobyl reactor core in Ukraine has lost its primary safety function of blocking radiation, as announced by the International Atomic Energy Agency (IAEA). This failure follows a drone strike earlier this year that caused significant damage in the protective shell.
An attack by an unmanned aerial vehicle in the second month of the year severely damaged the multibillion-euro “New Safe Confinement” arch. This massive shield, built at a cost of €1.5bn and completed in 2019, was intended to contain radiation over the long term. A recent IAEA inspection last week confirmed that the drone impact had weakened the integrity of the steel arch.
The containment arch's main safety functions, such as confinement, are no longer operational, said IAEA director general Rafael Grossi. He added that inspectors found no permanent damage to key support structures or monitoring systems.
The original 1986 explosion at the Chernobyl plant – at a time when Ukraine was part of the Soviet Union – released radiation across Europe. In a hurried containment effort, Soviet engineers constructed a concrete shelter over the damaged reactor, but it had a 30-year lifespan. The New Safe Confinement was erected to enable the eventual decommissioning of the old sarcophagus, the damaged reactor building, and the molten fuel itself.
Although limited repair work has been done, the IAEA emphasized that comprehensive restoration is essential. This is needed to stop additional deterioration and to ensure long-term nuclear safety. Officials in Ukraine previously reported that a unmanned aircraft armed with a high-explosive warhead struck the facility, causing a fire and compromising the outer shielding.
These developments underscore the persistent risks at one of the world's most infamous nuclear disaster sites during ongoing armed conflict.
