Russia and Iran have signed a massive agreement to build eight nuclear reactors.
On June 9, 2025, Russia and Iran finalized a key agreement to build eight nuclear reactors in Iran, announced Ebrahim Rezaei, spokesperson for Iran’s National Security Commission. This strategic move deepens energy cooperation between Moscow and Tehran and supports the development of Iran’s civilian nuclear power sector.
Locations and Co-Financing: Bushehr and Iran-Hormoz
Four new reactors will be constructed in Bushehr, where the existing Iran-Russia 1000 MW nuclear power plant, commissioned by Rosatom in 2011, is already operating. Another four reactors will be built as part of the Iran-Hormoz project in the southern Hormozgan province, near Minab and Sirik, with an estimated total capacity of 5 GW and a cost of around 15 billion USD. Russia will provide technology and nuclear fuel, as well as financial backing, offering loans to support the contracts, including further expansion phases at Bushehr.
A Civilian Project with Geopolitical Significance
Iran emphasizes that the ambitious reactor construction is purely peaceful and complies with international nuclear safety standards. The investment aims to meet the country’s growing energy demand and counter the effects of sanctions. At the same time, the agreement aligns with a deal for Russian natural gas supplies of 55 billion cubic meters annually—equivalent to the volume of Nord Stream 1.
Currently, Iran operates one active reactor in Bushehr, with a second unit under construction at the same site. Four additional reactors will be built in southern Iran with Russian support. Iran also plans a 300 MW nuclear power plant in Khuzestan province, demonstrating the rapid development of its national nuclear program.
International Reactions and Security Concerns
The agreement raises international concerns about the potential enhancement of Iran’s nuclear capabilities. Mohammad Eslami from the Atomic Energy Organization of Iran has assured that the project is solely for peaceful purposes. However, in the context of regional tensions—including Israeli strikes on Iranian nuclear sites (e.g., Natanz) and U.S. concerns over Iran’s uranium enrichment programs—the project carries not only economic but also geopolitical implications.
Russia as a Key Nuclear Partner
Rosatom is a central player in this agreement, providing reactor technology, fuel, and financing. This reflects Russia’s export strategy in the nuclear sector, where Moscow expands its influence through long-term, comprehensive energy projects. The Russia-Iran cooperation also spans the gas, oil, agriculture, and banking sectors, with contracts valued in the billions of dollars.
A New Dynamic in Middle Eastern Geopolitics
This strategic partnership fits into a broader pattern of deepening ties between Russia and Tehran—not only economically but militarily. Russia imports Iranian drones, and both countries coordinate regional activities, strengthening their position amid Western sanctions.
The agreement to build eight nuclear reactors marks a historic step in the development of Iranian energy. Its impact is multifaceted: it strengthens Iran’s energy security, extends Rosatom’s global reach, and cements deep integration between the two nations. Simultaneously, it raises international apprehensions regarding possible military-nuclear implications and Iran’s growing dependence on Moscow. For these reasons, its implementation will be closely monitored by the public and nuclear oversight agencies.
