Overview
- IAEA said November 19 attacks severed dedicated transmission lines at the Khmelnytskyi, Rivne and South Ukraine plants, prompting four of nine reactors to lower generation.
- Khmelnitskyi and Rivne had already been operating below capacity for nearly two weeks after a substation critical to nuclear safety was damaged.
- Zaporizhzhya’s main 750 kV Dniprovska line was reconnected after repairs, restoring off‑site power redundancy following a recent protection‑triggered disconnection.
- IAEA teams at Khmelnytskyi and Rivne sheltered during air‑raid alerts, and the South Ukraine plant reported detecting 11 drones roughly one kilometre from the site.
- Energoatom told Reuters that damage to transmission lines has forced nuclear output cuts and left hundreds of thousands without electricity, while a Russian envoy accused Ukraine of attacking nuclear facilities, a claim reported as disputed.
