IAEA Confirms Syrian Reactor Attempt, Undeclared Materials
The IAEA confirmed Syria's former government attempted a nuclear reactor at Deir Az Zor and had undeclared materials, following new access.

The International Atomic Energy Agency (IAEA) confirmed on Tuesday that Syria's previous government had attempted to build a nuclear reactor in the Deir Az Zor province. This confirmation followed confidential reports detailing inspections in August, which identified cooling infrastructure at the site consistent with nuclear reactor design specifications. The agency’s investigation progressed significantly after Syria's political transition post-2024, enabling new access for international inspectors to previously restricted areas.
This cooperation allowed the IAEA to verify that the former regime had not declared various nuclear facilities and activities. These undeclared sites included a plant for fuel fabrication and several locations used for storing uranium waste. The findings underscore the extent of the prior government's undisclosed nuclear ambitions.
Undeclared Uranium Discoveries
During recent inspections, officials verified the discovery of approximately 73 tonnes of natural uranium metal at a newly disclosed site. This significant quantity of material has since been placed under international containment and surveillance, marking a crucial step in addressing past non-compliance. The identification of undeclared nuclear material and facilities highlights a long-standing issue of international concern regarding Syria's nuclear activities.
The Deir Az Zor site itself has attracted global attention for over a decade. In 2007, the site, then believed to be a nascent nuclear reactor, was destroyed by an airstrike. For many years, the former Syrian government consistently denied the nuclear nature of the site and obstructed international efforts to investigate its true purpose. The IAEA's latest findings corroborate suspicions that had been held for a considerable period regarding Syria's undeclared nuclear program.
Future Civilian Nuclear Intentions
This development signals a notable move towards regional transparency, particularly as the current Syrian government has indicated an intention to pursue a civilian nuclear energy program. This prospective program is anticipated to operate under the full scope of international safeguards, a commitment that aligns with global non-proliferation efforts. Such a move could foster greater trust with the international community, promoting stability in the region.
The IAEA continues its monitoring activities at the Deir Az Zor site. Ongoing excavation and verification work aims to fully reconcile historical discrepancies and undeclared activities attributed to the previous administration. The agency's sustained engagement remains crucial for ensuring that all past nuclear materials and activities are properly accounted for and brought under international supervision, thus reinforcing the global nuclear non-proliferation regime and preventing future proliferation risks.
