🔗 Share this article Chornobyl Disaster Containment Structure Can No Longer Blocks Harmful Radiation, Needs Significant Restoration – International Atomic Energy Agency A containment structure encasing the Chornobyl reactor core within Ukraine has lost its primary function of containing radioactive material, as announced by the IAEA. This failure follows a drone strike in February that caused significant damage in the protective shell. Damage from Drone Strike Compromises Containment Structure An attack by an unmanned aerial vehicle in the second month of the year severely damaged the multibillion-euro “New Safe Confinement” arch. This enormous protective structure, constructed for €1.5bn with work finishing in 2019, was intended to seal off radioactive material over the long term. A recent IAEA inspection last week confirmed that the strike had degraded the structural integrity of the steel arch. The containment arch's main safety functions, such as confinement, are no longer operational, said IAEA head Rafael Grossi. He added that inspectors found no permanent damage to key support structures or monitoring systems. Background Context of the Chornobyl Containment The initial 1986 disaster at Chornobyl – which occurred when Ukraine was part of the Soviet Union – released radioactive fallout across Europe. In a hurried response, Soviet engineers built a concrete “sarcophagus” over the damaged reactor, but it had a three-decade design life. The New Safe Confinement was erected to allow for the future dismantling of the original structure, the destroyed reactor hall, and the melted nuclear fuel within. Present Status and Required Actions Although limited repairs have been carried out, the IAEA emphasized that comprehensive restoration is absolutely necessary. This is needed to stop additional deterioration and to guarantee long-term nuclear safety. Ukrainian authorities previously reported that a drone armed with a high-explosive warhead hit the facility, causing a fire and compromising the outer shielding. Radiation Levels: Authorities confirmed background radiation remained within safe limits following the attack with no reports of any leakage. Conflict Background: Moscow's troops occupied the Chernobyl exclusion zone for more than 30 days during the initial phase of the 2022 invasion. Broader Inspection: The IAEA conducted this inspection concurrently with a country-wide assessment of conflict-related damage to the country's electricity infrastructure. These developments highlight the persistent risks at one of the world's most notorious nuclear disaster sites amid continued hostilities.
