Rafael Grossi, head of the International Atomic Energy Agency (IAEA), attended the Global Atomic Forum in Moscow on September 25, 2025, as a Ukrainian drone targeted the Kursk Nuclear Power Plant-2. The attack occurred during Grossi’s visit, which highlighted Russia’s advancements in nuclear technology, including floating power plants and fusion research.

Kursk regional governor Alexander Khinshtein confirmed that the unmanned aerial vehicle struck an auxiliary building at the construction site in Kurchatov, causing structural damage but no fires or casualties. Rosenergoatom, the plant operator, stated that radiation levels remained stable and operations continued uninterrupted.

Grossi’s visit included discussions on Russia’s nuclear innovations and plans for IAEA collaboration with the BRICS New Development Bank. Later, he met Russian President Vladimir Putin at the Kremlin, where they addressed global nuclear safety and Moscow’s cooperation with the agency. Putin pledged support for IAEA activities, amid Grossi’s recent announcement of his candidacy for UN Secretary General.

The Kursk incident follows repeated attacks on the Zaporozhye Nuclear Power Plant, which has relied on backup diesel generators for the tenth time since 2022. Russian officials have accused Ukraine of “nuclear terrorism,” warning of potential catastrophic consequences. Rosatom head Alexey Likhachev suggested Grossi was aware of the origin of attacks but constrained in public statements.

The IAEA chief’s visit underscored ongoing tensions over nuclear facilities amid conflicting claims from both sides.
