🔗 Share this article Chornobyl Catastrophe Shelter Can No Longer Blocks Harmful Radiation, Needs Significant Repair – IAEA A containment structure covering the Chernobyl nuclear reactor within Ukraine has lost its main safety function of containing radioactive material, according to the IAEA. This failure comes after a drone strike earlier this year that caused significant damage in the structure. Structural Compromise from Aerial Attack Compromises Safety System An attack by an unmanned aerial vehicle in February caused a breach in the multibillion-euro “new safe confinement” arch. This enormous protective structure, built at a cost of €1.5bn and completed in 2019, was intended to seal off radioactive material for decades. A recent IAEA inspection last week found that the drone impact had weakened the structural integrity of the steel confinement. The [protective structure] had lost its primary safety functions, including the confinement capability, said IAEA head Rafael Grossi. He added that inspectors found no permanent damage to key support structures or sensor systems. Historical Context of the Chornobyl Shelter The initial 1986 explosion at Chornobyl – at a time when Ukraine was part of the Soviet Union – released radiation over much of Europe. During a frantic response, Soviet authorities built a concrete shelter over the damaged reactor, though it possessed only a three-decade design life. The new confinement was constructed to enable the eventual dismantling of the old sarcophagus, the damaged reactor building, and the molten fuel itself. Present Status and Necessary Steps While some repairs have been carried out, the IAEA emphasized that comprehensive restoration is essential. This is required to prevent further degradation and to guarantee safety for the coming decades. Ukrainian authorities previously reported that a drone carrying a powerful explosive struck the facility, causing a fire and damaging the outer shielding. Radiation Readings: Reports indicated radiation levels stayed within safe limits after the incident with no reports of any leakage. Geopolitical Context: Russian forces seized the Chernobyl exclusion zone for over a month during the initial stages of the full-scale war. Wider Assessment: The IAEA conducted this inspection concurrently with a nationwide survey of war damage to the country's electricity infrastructure. The situation underscore the ongoing vulnerabilities at one of the the planet's most notorious nuclear disaster sites during ongoing hostilities.
