Venezuela Removes 13.5 kg of Highly Enriched Uranium Abroad
Authorities disclosed that at the end of April, 13.5 kg of highly enriched uranium was taken out of Venezuela from an old research reactor near Caracas. The operation, reported around 06:02 UTC on 10 May, involved Venezuela, the United States, the United Kingdom, and the IAEA.
Key Takeaways
- Venezuela has transferred 13.5 kg of highly enriched uranium (HEU) out of the country.
- The material came from the decommissioned RV-1 research reactor near Caracas and was removed at the end of April 2026.
- The operation involved coordination among Venezuelan authorities, the United States, the United Kingdom, and the International Atomic Energy Agency (IAEA).
- The move reduces proliferation risks in a politically volatile region and signals limited nuclear cooperation despite broader geopolitical tensions.
On 10 May 2026, at approximately 06:02 UTC, information emerged that 13.5 kilograms of highly enriched uranium had been removed from Venezuela at the end of April. The nuclear material originated from the aging RV-1 research reactor near Caracas, which has long been out of service but still housed sensitive fuel. The transfer was reportedly organized jointly by Venezuelan authorities, the United States, the United Kingdom, and overseen by the International Atomic Energy Agency.
Highly enriched uranium, depending on enrichment level, can be directly usable in nuclear weapons or serve as a significant proliferation risk if stored under inadequate safeguards. Research reactors supplied during earlier eras of nuclear cooperation have become a focus of international clean-out campaigns aimed at reducing global HEU stockpiles and consolidating them in secure facilities. Venezuela’s participation in such an operation is notable given its strained relations with Western governments and alignment with other states critical of US policy.
The RV-1 reactor, built decades ago for scientific and medical research, had effectively become a nuclear legacy site, with aging infrastructure and fuel that no longer served an active civilian purpose. By agreeing to transfer the 13.5 kg of HEU out of the country, Caracas both eliminates a potential security liability and demonstrates at least selective engagement with international nuclear norms and institutions.
Key players in the operation include the Venezuelan nuclear and security authorities who authorized and facilitated the removal, technical teams from partner states who organized secure transport, and the IAEA, which likely provided verification and safety oversight. The material was moved overland from the reactor site to a port and then shipped by sea to a destination with facilities capable of safely storing, down-blending, or reprocessing the HEU.
This development matters because it directly reduces the risk that a politically unstable environment could lead to theft, diversion, or misuse of weapons-usable nuclear material. Latin America is generally free of nuclear weapons, formalized through regional treaties, and Venezuela’s HEU stockpile was an outlier in an otherwise low-risk nuclear landscape. The removal aligns the country more closely with regional non-proliferation norms.
At the regional level, the operation reinforces the message that even states with contentious political relations can cooperate on technical non-proliferation measures. Neighboring countries, some of which have expressed concern in the past about Venezuela’s security posture and internal stability, may view the HEU removal as a confidence-building step.
Globally, the transfer contributes to long-running international efforts to minimize civilian use of HEU and consolidate such materials in a smaller number of secure locations. It also illustrates that cooperation on nuclear security can proceed even when broader diplomatic relations are adversarial. For the United States and United Kingdom, the operation provides a tangible non-proliferation success at a time when global arms control frameworks are fraying.
Outlook & Way Forward
In the near term, additional details may emerge regarding the final destination of the HEU and the technical processes planned for it, such as down-blending to low-enriched uranium for reactor fuel. Venezuela may leverage the operation in public messaging to portray itself as a responsible actor in nuclear matters, even as political disputes with Western states continue.
Over the medium term, this episode could serve as a model for similar clean-out operations in other countries holding residual HEU from legacy research programs. International organizations and donor states may cite the Venezuelan case when seeking cooperation from governments concerned about sovereignty or political optics. It could also open space for limited technical dialogues between Caracas and Western capitals on related issues like radiological security and emergency response.
Strategically, observers should watch for whether Venezuela undertakes further steps to align with IAEA best practices, such as enhanced safeguards or upgraded security at remaining nuclear and radiological sites. Conversely, if broader political tensions escalate, there is a risk that this cooperation will remain an isolated success rather than a gateway to more comprehensive engagement. Nonetheless, the physical removal of the HEU is a durable non-proliferation gain that cannot easily be reversed, and it marginally reduces global nuclear security risk.
