Power Cuts and Conflicting Claims Put Zaporizhzhia Nuclear Plant Safety Under Scrutiny
A sustained rise in complete off‑site power losses has forced diesel backups and put reactor cooling at risk, raising international concern over who is responsible.
Overview
- Greenpeace Ukraine and London‑based McKenzie Intelligence Services published a satellite analysis on Thursday that found no evidence to support Russian claims that Ukrainian artillery or drone strikes caused specific switchyard damage near the plant.
- Russian officials including ZNPP director Yury Chernichuk and Rosatom CEO Alexey Likhachev tell the IAEA that Ukraine’s attacks have wounded about 100 people and killed nine, and that continuous strikes are making conditions unbearable for staff.
- Since Russia seized the plant in 2022 the ZNPP has suffered 26 complete losses of off‑site power, with 14 of those blackouts occurring since February 2026 and each incident forcing reliance on emergency diesel generators for cooling systems.
- The Dniprovska 750 kV line has been out of service since 22 May 2026 after severe damage to its substation, and the plant now depends on a single remaining external line and backup generators to maintain safety functions.
- IAEA mission experts remain permanently on site and continue monitoring the plant, while the dispute between Russian official attributions and independent forensic findings deepens diplomatic and safety concerns for workers and Energodar residents.
