Zaporizhzhia Nuclear Plant Restores Power Amid Ceasefire and Drone Attack
6/6/2026, 10:54:23 PM
Power Line Restored Under Temporary Ceasefire
The Russian-installed management of the Zaporizhzhia Nuclear Power Plant (ZNPP) announced on June 6 that the Ferrosplavnaya-1 external power line had been repaired and that “all systems and equipment at the ZNPP are operating normally.” The restoration followed a locally brokered ceasefire, mediated by the International Atomic Energy Agency (IAEA), intended to allow safe repairs to the plant’s power infrastructure.
Background and Context
Zaporizhzhia, Europe’s largest nuclear facility with six reactors, was seized by Russian forces in the early weeks of Moscow’s invasion of Ukraine. Although the plant does not generate electricity for the grid, it relies on external power to keep its nuclear fuel from overheating. Since late 2022, six ceasefires have been negotiated to enable repairs of damaged power lines after repeated attacks.
Key Figures and Organizations
- Rosatom – Russia’s state nuclear energy corporation, overseeing the plant’s operations.
- Alexei Likachev – Head of Rosatom, who described the June 5 drone strike as “clearly calculated.”
- Rafael Grossi – Director General of the IAEA, who called for “maximum military restraint and full adherence to the ceasefire.”
- Plant’s Russian-installed management – Communicates operational updates via Telegram.
Timeline of Recent Developments
- June 5 – A ceasefire is declared to permit repairs of the Ferrosplavnaya-1 line.
- June 5 (early hours) – A Ukrainian drone strikes engineers de-mining the plant’s perimeter, injuring at least three workers, according to Rosatom.
- June 5 (later) – Rosatom issues statements accusing Ukraine of violating the ceasefire and of deploying more than 20 drones against a nearby thermal plant.
- June 5 – IAEA receives notice of the incident and reiterates the need for restraint.
- June 6 – Plant management confirms the power line’s restoration and normal operation of plant systems.
Data and Statistics
- Six reactors at ZNPP.
- Injuries reported: three engineers (Rosatom) with two in serious condition; a later Rosatom statement cites five injured.
- This is the sixth ceasefire since late 2022 aimed at repairing external power lines.
Why It Matters
External electricity is essential to prevent overheating of nuclear fuel. Disruptions increase the risk of safety breaches, drawing heightened scrutiny from the international community and raising concerns about potential radiological hazards in an active conflict zone.
Official Statements and Responses
Rosatom asserted that the drone attack was a deliberate breach of the ceasefire, emphasizing calculated intent and the need for the international community to recognize ongoing attempts to damage the plant. The IAEA, through Director General Grossi, urged all parties to observe the ceasefire fully and to exercise maximum restraint. Plant management, via its Telegram channel, reported that all systems were functioning normally after the line’s repair.
Criticism and Opposition
Ukraine did not provide an immediate comment on the incident, leaving the allegation of a deliberate drone strike unchallenged in the public record. The absence of a Ukrainian response has been noted as a gap in the narrative.
Conflicting Reports and Gaps
Sources differ on the number of injured personnel—three versus five—and on the condition of the plant’s second external power line, which remained down after attacks on two substations across the Dnipro River. No independent verification of the drone strike’s origin is available.
Verbatim Quotes
- “All systems and equipment at the ZNPP are operating normally,” — Plant management, Telegram
- “The strike was clearly calculated,” — Alexei Likachev, Rosatom head
- “Three of our engineers were injured. Two are in serious condition.” — Alexei Likachev, Rosatom head
- “The international community must know of the continuing attempts to inflict maximum damage on the Zaporizhzhia Nuclear Power Plant, on the personnel responsible for ensuring its safety...despite the agreements that have been reached.” — Alexei Likachev, Rosatom head
What’s Next
The IAEA will continue monitoring ZNPP’s safety conditions while additional repairs to the second external power line are planned. Future ceasefires may be negotiated to address remaining infrastructure damage, and international observers are expected to assess compliance with nuclear safety protocols.
