🔗 Share this article Chornobyl Disaster Containment Structure Can No Longer Blocks Radiation, Needs Significant Repair – IAEA The protective shield covering the Chornobyl nuclear reactor in Ukraine has lost its primary safety function of containing radioactive material, according to the IAEA. This failure follows a drone attack in February that blew a hole in the structure. Structural Compromise from Aerial Attack Compromises Containment System An attack by an unmanned aerial vehicle in February caused a breach in the so-called “New Safe Confinement” arch. This enormous protective structure, constructed for €1.5bn with work finishing in 2019, was designed to contain radiation over the long term. An IAEA assessment mission found that the strike had degraded the structural integrity of the steel arch. The [protective structure] had lost its primary safety functions, including the confinement capability, stated IAEA head Rafael Grossi. He added that the mission confirmed no permanent damage to key support structures or monitoring systems. Background Context of the Chornobyl Containment The original 1986 explosion at the Chernobyl plant – which occurred when Ukraine was a republic within the Soviet Union – spewed radioactive fallout over much of Europe. During a frantic response, Soviet authorities constructed a concrete shelter over the ruined reactor, but it had a 30-year lifespan. The New Safe Confinement was constructed to enable the eventual dismantling of the original structure, the destroyed reactor hall, and the molten fuel itself. Present Status and Required Actions Although limited repair work has been done, the IAEA emphasized that comprehensive restoration is absolutely necessary. This is needed to prevent further degradation and to ensure safety for the coming decades. Ukrainian authorities had stated that a unmanned aircraft carrying a high-explosive warhead hit the facility, causing a fire and damaging the protective cladding. Radiation Readings: Reports indicated radiation levels remained normal and stable after the incident with no indication of any leakage. Geopolitical Context: Russian forces seized the Chernobyl exclusion zone for over a month in the early stages of the full-scale war. Broader Inspection: The IAEA conducted this inspection alongside a country-wide assessment of war damage to Ukraine's power substations. The situation highlight the persistent risks at one of the world's most infamous nuclear disaster sites amid ongoing armed conflict.
