​Russia’s ongoing attacks on Ukraine’s power grid have created dangerous conditions at two nuclear facilities, with a drone strike cutting power to Chernobyl for over three hours and the Zaporizhzhia plant operating on emergency generators for more than a week.

Some key facts:



• A Russian drone attack knocked out power for more than three hours at the Chernobyl nuclear disaster site, affecting cooling systems and radiation monitoring equipment.

• The Zaporizhzhia nuclear power plant, one of the world’s 10 biggest nuclear facilities, has been disconnected from the grid for over a week and is relying on emergency diesel generators.

• Both facilities require constant power to run cooling systems for spent fuel rods to prevent a potential nuclear incident.

• More than 20 Shahed drones targeted energy infrastructure in Slavutych, the city that provides power to Chernobyl, overwhelming defenses and causing a blackout.

• Ukrainian President Volodymyr Zelenskyy criticized the International Atomic Energy Agency and its chief, Rafael Mariano Grossi, for what he called weak responses to the nuclear threat.

• Nuclear safety experts warn that Zaporizhzhia’s situation is “extremely fragile and increasingly dire,” with no nuclear plant designed to function safely for extended periods without stable off-site power.

• The U.S.-based Institute for the Study of War claims Russia wants to integrate the Zaporizhzhia plant into the Russian grid, which would exacerbate security risks.
