🔗 Share this article Chornobyl Disaster Shelter No Longer Effectively Blocks Harmful Radiation, Needs Major Repair – IAEA A containment structure covering the Chornobyl reactor core within Ukraine can no longer perform its primary function of containing radioactive material, as announced by the IAEA. This failure follows a drone strike in February that blew a hole in the protective shell. Damage from Aerial Attack Degrades Safety Structure A drone strike in February severely damaged the so-called “new safe confinement” structure. This enormous protective structure, built at a cost of €1.5bn and completed in 2019, was designed to contain radiation over the long term. An IAEA inspection last week found that the strike 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. Grossi noted that the mission confirmed no permanent damage to key support structures or sensor systems. Background Context of the Chernobyl Containment The original 1986 explosion at Chornobyl – at a time when Ukraine was a republic within the Soviet Union – spewed radiation over much of Europe. During a frantic containment effort, Soviet authorities built a concrete shelter over the ruined reactor, but it had a three-decade design life. The new confinement was constructed to allow for the eventual decommissioning of the original structure, the destroyed reactor hall, and the melted nuclear fuel within. Current Situation and Required Steps While some repair work has been done, agency officials stressed that a full-scale repair effort is essential. This is needed to prevent further degradation and to ensure long-term nuclear safety. Officials in Ukraine had stated that a unmanned aircraft carrying a high-explosive warhead struck the facility, igniting a blaze and compromising the protective cladding. Radiation Readings: Authorities confirmed radiation levels stayed normal and stable after the incident with no indication of any leakage. Conflict Background: Moscow's troops seized the Chernobyl exclusion zone for more than 30 days during the initial phase of the full-scale war. Wider Assessment: The IAEA carried out this review concurrently with a nationwide survey of war damage to the country's power substations. The situation highlight the ongoing vulnerabilities at one of the world's most infamous atomic accident locations amid continued armed conflict.
