🔗 Share this article Chornobyl Catastrophe Containment Structure Can No Longer Effectively Blocks Harmful Radiation, Requires Major Repair – IAEA The protective shield covering the Chernobyl nuclear reactor in Ukraine has lost its primary safety function of blocking radiation, as announced by the IAEA. This loss of function comes after a drone attack in February that caused significant damage in the structure. Damage from Drone Strike Compromises Safety Structure A drone strike in the second month of the year severely damaged the multibillion-euro “New Safe Confinement” structure. This massive shield, built at a cost of €1.5bn with work finishing in 2019, was intended to contain radiation over the long term. An IAEA assessment mission found that the strike had weakened the integrity of the steel confinement. 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 Chernobyl Containment The initial 1986 explosion at Chornobyl – which occurred when Ukraine was a republic within the USSR – spewed radioactive fallout over much of Europe. During a frantic response, Soviet authorities constructed a concrete “sarcophagus” over the damaged reactor, but it had a 30-year lifespan. The New Safe Confinement was constructed to allow for the future decommissioning of the old sarcophagus, the damaged reactor building, and the molten fuel itself. Present Status and Required Steps Although limited repair work has been done, the IAEA emphasized that comprehensive restoration is absolutely necessary. This is required to stop additional deterioration and to guarantee 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 protective cladding. Radiation Readings: Reports indicated background radiation stayed within safe limits following the attack with no indication of radiation leaks. Geopolitical Context: Moscow's troops occupied the Chernobyl exclusion zone for more than 30 days during the initial phase of the 2022 invasion. Wider Assessment: The agency conducted this review concurrently with a nationwide survey of conflict-related damage to Ukraine's electricity infrastructure. The situation underscore the ongoing vulnerabilities at one of the world's most notorious atomic accident locations amid continued armed conflict.
