Zelensky Reports Russian Drone Attack on Chernobyl Nuclear Waste Storage; No Leak

A Russian Shahed kamikaze drone struck the Centralized Spent Fuel Storage Facility at Chornobyl at 2:10 AM on June 7, 2026, hitting the container reception building and sparking a 40-square-meter fire. Ukrainian authorities extinguished the blaze within one hour and detected no radiation leak, according to Energoatom and Kyiv Post.
President Volodymyr Zelenskyy called the attack "extremely vile" and "deliberate," stating: "There is no heightening of radiation safety limits. But there is clearly a heightening of Russia's already sky-high arrogance." The strike drew immediate condemnation from the IAEA and Western leaders, according to The Guardian.
The reception building struck by the drone is part of the CSFSF — a dry storage site designed to hold up to 16,530 spent fuel assemblies from Ukraine's active nuclear plants. The facility sits about 15 kilometers from the main Chornobyl reactor, according to Kyiv Post. Ukraine built it to stop paying Russia $200 million a year for fuel reprocessing.
IAEA Director General Rafael Grossi said the building was empty of containers at the moment of impact. But the blast wave reached nearby structures where nuclear material is stored. Grossi called this "extremely concerning" because the strike compromised the safety buffer required under international standards, according to Ukrinform.
Ukraine's General Staff labeled the strike "an act of nuclear terrorism." Foreign Minister Andrii Sybiha accused Russia of "nuclear blackmail" and called threats to nuclear safety "systemic and unacceptable," according to The Guardian. Deputy Prime Minister Denys Shmyhal described it as "an unprecedented threat to nuclear and radiation safety" and "a blatant violation of international law," per Anadolu Agency.
Russia did not comment specifically on the Chornobyl strike. Instead, the Russian Ministry of Defense focused on claiming it had shot down more than 500 Ukrainian drones in a single 24-hour window, following Ukraine's own long-range attacks on Kronstadt and Saint Petersburg the night before, according to Interfax.
This is not the first time Russia has targeted Chornobyl. In February 2025, a Russian drone hit the New Safe Confinement arch covering the destroyed Reactor 4. That strike damaged the structure but caused no leak. In 2022, Russian forces occupied the Chornobyl site for five weeks, digging trenches in the radioactive "Red Forest," according to El Periódico de España.
Environmental experts have warned that repeated near-misses degrade the structural integrity of confinement systems over time. Even minor future impacts could trigger a radiological release, according to previous reports cited by Greenpeace Ukraine. The IAEA has a formal framework — the "Seven Pillars of Nuclear Safety" — that this strike is said to violate.
The IAEA announced an inspection mission to the site shortly after the strike was confirmed, according to Ukrinform. The attack landed on the same day UK Prime Minister Keir Starmer, French President Emmanuel Macron, and German Chancellor Friedrich Merz were set to meet Zelenskyy in London to discuss security guarantees and air defense support for Ukraine, per AP.
Analysts expect the strike to accelerate plans for dedicated air defense systems around Ukrainian nuclear sites. Damage to the reception building also risks creating bottlenecks in nuclear waste management across Ukraine's active reactor fleet, potentially jeopardizing the stability of the national power grid, according to Energoatom.
