Overview
- IAEA mediation secured a temporary local ceasefire that let repair teams fix the 750 kV Dniprovska power line and restored full site power at the Zaporizhzhya nuclear plant.
- The outage followed a complete loss of off‑site power that lasted about a month and required diesel generators to keep critical cooling systems running.
- This event was the tenth full loss of off‑site power since Russian forces took control of the site in March 2022, and the reactors still contain nuclear fuel that needs continuous cooling.
- The plant has suffered roughly 19 outages or near‑misses linked to fighting and the IAEA has negotiated at least six local ceasefires to allow repairs and inspections.
- All six reactors remain offline, forcing Ukraine to replace about one fifth of its former supply and raising long‑term safety concerns that repeated outages could exhaust backups and risk cross‑border radiological consequences.
