🔗 Share this article Chornobyl Catastrophe Shelter No Longer Effectively Blocks Harmful Radiation, Requires Significant Restoration – IAEA A containment structure encasing the Chornobyl reactor core in Ukraine has lost its primary safety function of containing radioactive material, according to the IAEA. This failure comes after a drone strike earlier this year that blew a hole in the structure. Structural Compromise from Drone Strike Compromises Containment System An attack by an unmanned aerial vehicle in the second month of the year severely damaged the multibillion-euro “new safe confinement” structure. This massive shield, constructed for €1.5bn and completed in 2019, was intended to seal off radioactive material for decades. A recent IAEA assessment mission found that the strike had weakened the integrity of the steel arch. The [protective structure] had lost its primary safety functions, including the confinement capability, said IAEA head Rafael Grossi. Grossi noted that inspectors found no lasting harm to key support structures or sensor systems. Background Context of the Chornobyl Containment The initial 1986 explosion at Chornobyl – at a time when Ukraine was a republic within the Soviet Union – spewed radiation over much of Europe. In a hurried response, Soviet engineers constructed a concrete shelter over the ruined reactor, but it had a 30-year lifespan. The New Safe Confinement was erected to enable the future decommissioning of the original structure, the damaged reactor building, and the melted nuclear fuel within. Present Status and Required Actions Although limited repairs have been carried out, agency officials emphasized that a full-scale repair effort is essential. This is required to stop additional deterioration and to ensure safety for the coming decades. Officials in Ukraine previously reported that a drone carrying a high-explosive warhead struck the facility, causing a fire and compromising the outer shielding. Radiation Levels: Authorities confirmed background radiation stayed normal and stable following the attack with no indication of any leakage. Conflict Background: Moscow's troops occupied the Chornobyl site for more than 30 days in the early phase of the 2022 invasion. Wider Assessment: The agency carried out this review alongside a country-wide assessment of conflict-related damage to the country's power substations. These developments highlight the persistent risks at one of the the planet's most infamous atomic accident locations during continued armed conflict.
