🔗 Share this article Chornobyl Disaster Shelter No Longer Blocks Radiation, Needs Major Repair – International Atomic Energy Agency The containment structure covering the Chernobyl reactor core in Ukraine can no longer perform its primary function of blocking radiation, according to the IAEA. This loss of function comes after a drone strike in February that caused significant damage in the structure. Damage from Drone Strike Degrades Safety Structure A drone strike in February severely damaged the so-called “new safe confinement” structure. This enormous protective structure, constructed for €1.5bn and completed in 2019, was designed to contain radiation for decades. A recent IAEA assessment mission confirmed 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, stated IAEA director general Rafael Grossi. He added that inspectors found no permanent damage to its load-bearing structures or sensor systems. Historical Context of the Chornobyl Containment The initial 1986 explosion at Chornobyl – which occurred when Ukraine was part of the USSR – spewed radiation across Europe. During a frantic containment effort, Soviet authorities built a concrete shelter over the damaged reactor, but it had a three-decade design life. The New Safe Confinement was constructed to allow for the future dismantling of the old sarcophagus, the destroyed reactor hall, and the melted nuclear fuel itself. Present Status and Required Steps Although limited repairs have been carried out, the IAEA stressed that a full-scale repair effort is essential. This is needed to prevent further degradation and to ensure long-term nuclear safety. Ukrainian authorities previously reported that a unmanned aircraft carrying a powerful explosive hit the facility, causing a fire and damaging the protective cladding. Radiation Levels: Authorities confirmed background radiation stayed within safe limits after the incident with no indication of any leakage. Geopolitical Context: Russian forces seized the Chornobyl site for over a month during the initial phase of the 2022 invasion. Wider Assessment: The IAEA conducted this inspection alongside a nationwide survey of conflict-related damage to Ukraine's power substations. The situation underscore the ongoing vulnerabilities at one of the the planet's most notorious nuclear disaster sites during continued hostilities.
