Overview

• President Volodymyr Zelensky said one backup diesel generator has failed after seven days without external power, calling the situation critical.
• The outage is the plant’s tenth of the war and its longest to date, with the Russian-occupied facility relying on emergency power to cool shutdown reactors and safety systems.
• The IAEA reports radiation levels remain normal and says it is engaging both sides to restore off-site power, calling diesel generation the last line of defense.
• Responsibility for the severed line is disputed, as Russia blames Ukrainian fire while Kyiv accuses Moscow of obstructing repairs and warns of efforts to reconnect the plant to the Russian grid.
• Ukraine’s nuclear regulator warns uncertain diesel reserves could lead to a radiological emergency, and a recent drone incident near the South Ukraine plant highlights broader nuclear safety risks.
