🔗 Share this article Chernobyl Disaster Shelter Can No Longer Effectively Blocks Harmful Radiation, Needs Major Repair – IAEA A protective shield encasing the Chornobyl nuclear reactor in Ukraine can no longer perform its main safety function of containing radioactive material, according to the International Atomic Energy Agency (IAEA). This failure follows a drone attack earlier this year that caused significant damage in the structure. Damage from Drone Strike Compromises Safety System An attack by an unmanned aerial vehicle in February caused a breach in the so-called “New Safe Confinement” structure. This enormous protective structure, constructed for €1.5bn and completed in 2019, was designed to seal off radioactive material for decades. A recent IAEA assessment mission found that the strike had degraded the structural integrity of the steel confinement. The [protective structure] had lost its primary safety functions, including the confinement capability, said IAEA director general Rafael Grossi. Grossi noted that the mission confirmed no lasting harm to key support structures or sensor systems. Background Context of the Chornobyl Containment The original 1986 explosion at the Chernobyl plant – at a time when Ukraine was part of the Soviet Union – released radiation across Europe. In a hurried response, Soviet engineers built a concrete shelter over the ruined reactor, though it possessed only a three-decade design life. The new confinement was constructed to allow for the future decommissioning of the old sarcophagus, the damaged reactor building, and the melted nuclear fuel itself. Current Situation and Required Actions Although limited repair work has been done, the IAEA stressed that comprehensive restoration is absolutely necessary. This is required to stop additional deterioration and to guarantee safety for the coming decades. Officials in Ukraine had stated that a drone armed with a powerful explosive hit the facility, causing a fire and compromising the outer shielding. Radiation Readings: Reports indicated radiation levels stayed within safe limits following the attack with no indication of any leakage. Geopolitical Context: Russian forces seized the Chernobyl exclusion zone for more than 30 days during the initial stages of the 2022 invasion. Wider Assessment: The agency conducted this inspection alongside a country-wide assessment of war damage to the country's electricity infrastructure. The situation highlight the ongoing vulnerabilities at one of the the planet's most notorious atomic accident locations during continued hostilities.
