Rafael Mariano Grossi
Director General
Iternational Atomic Energy Agency (IAEA)

Dear Mr. Rafael Mariano Grossi,

October, 2, 2025

For the past three and a half years, the Zaporizhzhia Nuclear Power Plant—the largest in Europe—has remained under occupation by Russian forces. This period represents a tragic chapter of gross violations of international law, the human rights of Ukrainian workers at the plant, and the fundamental principles of nuclear and radiation safety.

Recent actions by the occupying forces have cut off external electricity supplies essential to the plant’s safety systems, significantly increasing the risk of a nuclear accident. The danger is so grave that Ukrainian authorities have already warned residents in neighboring regions to prepare for possible precautionary measures in the event of an explosion or release of radioactivity.

Ukraine, together with the broader international community, relies on the Iternational Atomic Energy Agency (IAEA) to exercise its mandate and help resolve this crisis. Yet, since the start of the occupation, the Agency’s stance has been marked by moderation and passivity. We have seen no meaningful pressure exerted on Russia, nor any substantial actions beyond observation and reporting.

Disturbingly, on September 25, 2025—amid the ongoing crisis at the plant—the IAEA leadership attended the celebration of Rosatom’s 80th anniversary in Moscow, and held a meeting with the Russian president.

In today’s world, where symbolic actions carry immense weight, such behavior only emboldens those who flout international law and security norms. The IAEA’s position and its ability to exert real influence are vital not only in addressing the current perilous situation but also in shaping the credibility and future of nuclear energy worldwide.

In light of these concerns, WePlanet Ukraine calls on the IAEA to take all necessary measures to restore safety at the Zaporizhzhia Nuclear Power Plant and to assume a visible and decisive role in determining its future.

We remain at your disposal for any further discussion about this topic, and we look forward to hearing from you.
