Overview
- Ukraine’s energy ministry reported that power to facilities at the Chernobyl site, including the New Safe Confinement, was cut after a strike on the Slavutych substation in Kyiv region.
- President Volodymyr Zelenskyy said the outage lasted more than three hours and alleged a deliberate attack using over 20 Shahed-type drones.
- The UN nuclear watchdog confirmed the blackout affected the confinement structure and said two diesel generators supplied electricity as teams worked to restore the grid connection.
- At the Russian‑occupied Zaporizhzhia plant, external power has been down for eight days, with generators maintaining cooling for six shutdown reactors as the IAEA warns this reliance cannot be sustained.
- Greenpeace and McKenzie Intelligence said satellite imagery showed no shelling crater at a damaged ZNPP pylon and alleged deliberate Russian sabotage, while Russian officials blamed Ukraine and a nuclear expert told TASS there was no disaster threat at Chernobyl.
