IAEA: Ukraine Poses Greatest Global Nuclear Safety Threat

The International Atomic Energy Agency (IAEA) has raised alarm as 13 member states, led by the Netherlands, urgently convened the IAEA Board of Governors on January 30, 2026, to address escalating nuclear safety risks in Ukraine following recent Russian strikes on the country’s energy infrastructure. IAEA Director General Rafael Mariano Grossi stated at the opening of the Vienna-based meeting: “The war in Ukraine remains the greatest threat to nuclear safety worldwide.” Ukrainian Ambassador Yuriy Vitrenko called for decisive action, urging the Board to formally address the crisis, while Dutch Permanent Representative Peter Potman emphasized growing concern over the severity and urgency of nuclear safety risks. An ongoing IAEA expert mission—assessing ten electricity substations critical for nuclear safety—is expected to conclude next month. Meanwhile, Russia dismissed the emergency session as politically motivated, with its Vienna-based envoy Mikhail Ulyanov denying any real technical need. Recent attacks disrupted external power supply to the Chernobyl plant, and although the Zaporizhzhia plant remains offline, it still requires stable electricity for reactor cooling. A local ceasefire earlier this month enabled repairs to the last functional backup power line feeding the facility.
