🔗 Share this article Chornobyl Disaster Shelter Can No Longer Effectively Blocks Radiation, Requires Significant Repair – International Atomic Energy Agency A protective shield encasing the Chernobyl reactor core in Ukraine can no longer perform its primary function of blocking radiation, as announced by the International Atomic Energy Agency (IAEA). This failure follows a drone strike earlier this year that blew a hole in the structure. Structural Compromise from Aerial Attack Degrades Containment System A drone strike in the second month of the year caused a breach in the so-called “New Safe Confinement” structure. This massive shield, built at a cost of €1.5bn and completed in 2019, was intended to contain radiation for decades. A recent IAEA assessment mission found that the strike had weakened the integrity of the steel arch. The containment arch's main safety functions, such as confinement, are no longer operational, said IAEA director general Rafael Grossi. He added that inspectors found no lasting harm to key support structures or monitoring systems. Background Context of the Chernobyl Containment The original 1986 disaster at the Chernobyl plant – which occurred when Ukraine was part of the USSR – spewed radioactive fallout over much of Europe. During a frantic containment effort, Soviet authorities built a concrete “sarcophagus” over the ruined reactor, but it had a 30-year lifespan. The New Safe Confinement was constructed to enable the eventual dismantling of the old sarcophagus, the damaged reactor building, and the molten fuel itself. Present Status and Required Actions While some 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 guarantee 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 Levels: Authorities confirmed background radiation stayed within safe limits after the incident with no reports of radiation leaks. Conflict Background: Moscow's troops seized the Chernobyl exclusion zone for more than 30 days during the initial phase of the full-scale war. Broader Inspection: The agency carried out this review alongside a nationwide survey of war damage to Ukraine's power substations. The situation highlight the ongoing vulnerabilities at one of the the planet's most notorious nuclear disaster sites during continued armed conflict.
