Event Summary

Ukraine is commemorating the 40th anniversary of the Chornobyl nuclear disaster amidst fears that Russia's ongoing war could lead to a repeat catastrophe. Russia has repeatedly sent missiles and drones near the Chernobyl Nuclear Power Plant, damaging its critical protective shield in a February 2025 strike, which requires 500 million euros in repairs according to the European Bank for Reconstruction and Development. Ukrainian radars have detected at least 92 Russian drones within a 5-km radius of the shield since June 2024. Additionally, the Zaporizhzhia Nuclear Power Plant, under Russian occupation, has experienced 15 temporary blackouts since March 2022. Ukrainian President Volodymyr Zelenskyy laid a candle at the Chernobyl Nuclear Power Plant, emphasizing the continued risks. The original 1986 disaster, caused by a reactor experiment and subsequent cover-ups, exposed millions to radiation and contaminated vast areas, with thousands succumbing to radiation-related illnesses. The International — International Atomic Energy Agency has urged prompt repairs to the Chornobyl plant's damaged arc.
