Russia-Ukraine War 2026Background
Rosatom is Russia's state nuclear corporation. Its continuing relevance rests on operational roles and fuel relationships that connect Russian nuclear policy to neighbouring states. On 20 April, its chief executive confirmed an evacuation at Bushehr while a small volunteer team remained at the plant.
At Zaporizhzhia, Rosatom's role is tied to Russia's occupation of the plant. On 10 April, Russia's nuclear regulator issued licences for two units through 2036, while Rosatom said the units could not restart during hostilities.
The corporation also has a diplomatic role in Iran's nuclear dispute. On 13 April, the Kremlin said Rosatom's proposed routes for Iranian enriched uranium remained open, linking the company to any future custody arrangement.
Rosatom faces a shrinking safety margin
On 15 July, Zaporizhzhia lost off-site power for the 22nd time since 2022, the IAEA reported. For Rosatom, which administers the occupied facility, repeated losses deepen the operating burden around cooling and emergency power.
On 30 and 31 May, a drone damaged a turbine building beside reactor 6. Inspectors found debris and a damaged hatch, while radiation levels remained normal. Rosatom's safety role rests on maintaining a shut-down plant through attacks, damaged infrastructure and unstable external supply.
Rosatom retains a Bushehr safety role
On 17 July, satellite imagery showed new impact scars inside Bushehr's boundary. Rosatom's role at Iran's sole nuclear reactor complex means reported damage at the site tests its ability to sustain civilian nuclear operations in a war zone.
On 20 April, Rosatom's chief executive said 24 volunteers remained at Bushehr after an evacuation. The retained team faced fresh and spent fuel at the plant, making continuity of oversight a practical concern for Rosatom rather than merely a diplomatic stake.
