🔗 Share this article Chernobyl Disaster Shelter No Longer Blocks Radiation, Needs Significant Restoration – International Atomic Energy Agency The protective shield covering the Chornobyl reactor core within Ukraine has lost its main safety function of blocking radiation, according to the International Atomic Energy Agency (IAEA). This failure follows a drone attack in February that blew a hole in the protective shell. Structural Compromise from Aerial Attack Degrades Safety Structure An attack by an unmanned aerial vehicle in the second month of the year severely damaged the multibillion-euro “new safe confinement” structure. This enormous protective structure, constructed for €1.5bn with work finishing in 2019, was intended to contain radiation over the long term. An IAEA assessment mission confirmed that the drone impact had degraded the structural integrity of the steel arch. The containment arch's main safety functions, such as confinement, are no longer operational, stated IAEA head Rafael Grossi. He added that the mission confirmed no lasting harm to key support structures or sensor systems. Historical Context of the Chernobyl Shelter The original 1986 explosion at Chornobyl – at a time when Ukraine was part of the Soviet Union – released radioactive fallout across Europe. In a hurried response, Soviet engineers constructed a concrete “sarcophagus” over the damaged reactor, but it had a 30-year lifespan. The New Safe Confinement was erected to allow for the eventual decommissioning of the old sarcophagus, the damaged reactor building, and the molten fuel itself. Current Situation and Required Steps Although limited repairs have been carried out, agency officials emphasized that a full-scale repair effort is essential. This is needed to prevent further degradation and to guarantee safety for the coming decades. Ukrainian authorities previously reported that a drone armed with a high-explosive warhead hit the plant, igniting a blaze and compromising the outer shielding. Radiation Levels: Authorities confirmed radiation levels remained normal and stable after the incident with no reports of radiation leaks. Geopolitical Context: Russian forces seized the Chernobyl exclusion zone for more than 30 days in the early phase of the full-scale war. Wider Assessment: The IAEA carried out this review concurrently with a country-wide assessment of conflict-related damage to Ukraine's electricity infrastructure. These developments underscore the persistent risks at one of the world's most infamous nuclear disaster sites amid continued armed conflict.
