Ukraine has accused Russia of launching an overnight drone strike on the Chernobyl radiation shield, the protective structure covering the remnants of the 1986 nuclear disaster. The attack reportedly caused a fire, which was quickly extinguished.
The International Atomic Energy Agency (IAEA), responsible for nuclear safety monitoring, confirmed that radiation levels inside and outside the Chernobyl Exclusion Zone remain stable. However, Oleksandr Titarchuk, the plant’s chief engineer, warned that there is now a possibility of radioactive leakage.
Russia has denied involvement, stating that its military does not target Ukrainian nuclear infrastructure and that any such claims are inaccurate.
According to the IAEA, emergency fire response teams arrived at the scene within minutes, and no casualties were reported. The agency remains on high alert, with Director General Rafael Grossi stressing that the situation should not be taken lightly.
Titarchuk reassured the public that the situation remains under control. However, concerns persist, given the history of the Chernobyl disaster, which spread radioactive contamination across Europe.
The radiation shield, designed to contain radioactive materials for the next century, spans 275 meters (900 feet) in width and 108 meters (354 feet) in height. Constructed at a cost of $1.6 billion, the structure plays a critical role in preventing further contamination.
Footage shared by Ukrainian President Volodymyr Zelensky appeared to show visible damage to the structure. Hryhoriy Ishchenko, head of the Chernobyl Exclusion Zone management agency, noted that had the strike landed just 15 meters (50 feet) away, a serious radiation incident could have occurred.
Nuclear expert Professor Jim Smith from the University of Portsmouth called the attack “a horrendous act against a crucial facility” but expressed confidence in the containment structure, noting that a thick concrete sarcophagus beneath the shield still secures radioactive particles.
Simon Evans, a former leader of the Chernobyl Shelter Fund at the European Bank for Reconstruction and Development (EBRD), described the strike as "incredibly reckless." He emphasized that the protective shield was not designed to withstand drone attacks and that the damage assessment must be completed to determine the full impact.
The attack has intensified tensions between Ukraine and Russia. President Zelensky stated that the strike demonstrated that Russian President Vladimir Putin is not genuinely preparing for peace negotiations.
This incident follows previous accusations from both Ukraine and Russia regarding drone strikes on nuclear sites, including an attack on an IAEA convoy en route to the Zaporizhzhia nuclear plant in December.
Professor Smith expressed greater concern over Zaporizhzhia, which, unlike Chernobyl, still houses active nuclear fuel. While Chernobyl remains highly radioactive, it is no longer in an active operational state.
The true death toll from the Chernobyl disaster remains disputed. Official records attribute 31 immediate deaths to the explosion, while UN estimates suggest around 50 fatalities. However, long-term projections indicate that thousands more may eventually die from radiation-related illnesses.
The latest attack has reignited concerns over the vulnerability of nuclear sites in conflict zones, with experts urging global efforts to prevent further escalation.
