🔗 Share this article Chornobyl Disaster Containment Structure Can No Longer Blocks Harmful Radiation, Requires Major Repair – IAEA The containment structure encasing the Chernobyl nuclear reactor within Ukraine has lost its primary function of containing radioactive material, according to the IAEA. This loss of function follows a drone strike earlier this year that caused significant damage in the protective shell. Structural Compromise from Drone Strike Compromises Safety System A drone strike in the second month of the year caused a breach in the so-called “new safe confinement” arch. This massive shield, constructed for €1.5bn with work finishing in 2019, was intended to contain radiation over the long term. A recent IAEA inspection last week found that the drone impact had weakened the integrity of the steel arch. The [protective structure] had lost its primary safety functions, including the confinement capability, said IAEA director general Rafael Grossi. He added that the mission confirmed no lasting harm to key support structures or monitoring systems. Historical Context of the Chernobyl Shelter The original 1986 explosion at Chornobyl – at a time when Ukraine was part of the USSR – released radiation over much of Europe. During a frantic containment effort, Soviet authorities constructed a concrete shelter over the ruined reactor, but it had a three-decade design life. The New Safe Confinement was constructed to allow for the eventual decommissioning of the original structure, the damaged reactor building, and the molten fuel within. Present Status and Necessary Steps Although limited repairs have been carried out, agency officials stressed that comprehensive restoration is absolutely necessary. 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 hit the plant, causing a fire and damaging the outer shielding. Radiation Levels: Authorities confirmed radiation levels remained normal and stable following the attack with no indication of any leakage. Geopolitical Context: Moscow's troops seized the Chornobyl site for more than 30 days in the early phase of the 2022 invasion. Broader Inspection: The IAEA carried out this review concurrently with a country-wide assessment of war damage to Ukraine's power substations. These developments highlight the persistent risks at one of the the planet's most notorious nuclear disaster sites amid continued armed conflict.
