🔗 Share this article Chornobyl Catastrophe Shelter No Longer Effectively Blocks Radiation, Needs Significant Restoration – International Atomic Energy Agency The containment structure encasing the Chornobyl reactor core in Ukraine can no longer perform its primary function of containing radioactive material, as announced by the IAEA. This failure follows a drone attack earlier this year that caused significant damage in the structure. Structural Compromise from Drone Strike Degrades Safety System A drone strike in the second month of the year caused a breach in the so-called “new safe confinement” arch. This enormous protective structure, constructed for €1.5bn and completed in 2019, was intended to contain radiation over the long term. A recent IAEA inspection last week confirmed that the drone impact had degraded the structural integrity of the steel arch. 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 lasting harm to key support structures or monitoring systems. Historical Context of the Chornobyl Shelter The original 1986 disaster at the Chernobyl plant – which occurred when Ukraine was a republic within the Soviet Union – released radiation across Europe. In a hurried response, Soviet authorities built a concrete shelter over the ruined reactor, but it had a three-decade design life. The New Safe Confinement was erected to enable the eventual dismantling of the original structure, the destroyed reactor hall, and the melted nuclear fuel within. Current Situation and Necessary Actions While some repair work has been done, the IAEA stressed that comprehensive restoration is essential. This is required to prevent further degradation and to ensure safety for the coming decades. Ukrainian authorities previously reported that a unmanned aircraft carrying a powerful explosive hit the facility, igniting a blaze and compromising the protective cladding. Radiation Readings: Authorities confirmed radiation levels remained normal and stable following the attack with no indication of any leakage. Conflict Background: Russian forces occupied the Chornobyl site for over a month in the early phase of the 2022 invasion. Broader Inspection: The IAEA carried out this review alongside a nationwide survey of conflict-related damage to the country's power substations. The situation highlight the persistent risks at one of the the planet's most infamous nuclear disaster sites during ongoing armed conflict.
