Overview

• The IAEA confirmed the plant was disconnected from its last 750 kV line at 16:56 on Sept. 23, triggering all emergency diesel generators to supply power.
• The site has been without external electricity for more than 48 hours, relying on emergency systems to cool reactors and spent fuel, which the agency says heightens the risk of an accident.
• Responsibility for the cut remains disputed, with Russian occupation officials blaming Ukrainian strikes and Ukraine’s Energoatom and Ukrenergo alleging Russian damage and refusal to reconnect the plant.
• The IAEA reported a drone was downed and detonated about 800 meters from the South Ukraine plant, observed 22 drones in the monitoring zone, and noted no damage to the facility though a nearby non‑plant power line fell.
• Russian regional authorities said a Ukrainian drone struck a building at the under‑construction Kursk NPP‑2 without casualties, as IAEA chief Rafael Grossi met Vladimir Putin in Moscow to discuss nuclear safety.
