Washington is negotiating a deal to secure Iran’s enriched uranium stockpiles, according to a senior U.S. administration official speaking to Reuters. While U.S. officials report progress on plans to remove and destroy the material, CNN reports that Iran has significantly fortified its storage sites by isolating uranium caches and booby-trapping tunnel entrances, complicating any potential extraction process.
What does the proposed nuclear agreement involve?
The emerging agreement centers on the removal of Iran’s enriched uranium in exchange for the lifting of U.S. sanctions, a U.S. official told Agence France-Presse. According to the senior administration official cited by Reuters, the deal includes a structured inspection regime and specific protocols for the destruction of the materials. The goal, as stated by these officials, is the systematic dismantling of Iran’s nuclear program. However, internal messaging remains inconsistent; Iranian state media outlet IRNA reported earlier that current memorandums do not include a final nuclear deal, noting that negotiations on that file would only begin after a 60-day period following any potential signing.

Iran is estimated to hold approximately 408 kilograms of highly enriched uranium, a figure that remains a central point of contention in international diplomatic efforts.
Why are Iran’s fortified tunnels complicating the deal?
Recent intelligence indicates that Iran has moved to isolate its stockpile of roughly 500 kilograms of highly enriched uranium, according to five sources cited by CNN. These sources report that Iranian forces have filled tunnels and installed explosive traps at entry points, making the material significantly harder to access than it was a month ago. This physical hardening creates a logistical hurdle for any extraction plan. Experts suggest these fortifications could allow Tehran to claim that portions of the stockpile are inaccessible, potentially providing a pretext to withhold materials and raising questions about compliance with future international agreements.
How do the parties differ on the enrichment issue?
There is a clear gap between the public rhetoric of U.S. officials and Iranian military leadership regarding the right to enrich. While U.S. representatives discuss the “dismantling” of the program, Iranian military advisor Major General Mohsen Rezaei stated that Tehran views uranium enrichment as a national resource for medical, agricultural, and power-generation purposes. Rezaei explicitly claimed that Iran would not hand over enriched materials to any entity. This stance contrasts with the U.S. position, which prioritizes the removal of the stockpile as a precondition for economic relief.
Comparison of Recent Diplomatic Moves
| Source | Key Claim |
|---|---|
| U.S. Administration | Agreement reached on destroying and removing enriched material. |
| IRNA (Iranian Media) | Current memorandum excludes nuclear file; talks to start post-signing. |
| IAEA | Prioritizing verification of full nuclear capabilities. |
What role is the IAEA playing?
The International Atomic Energy Agency (IAEA) is moving to tighten oversight of Iran’s facilities. Director General Rafael Grossi stated that verifying the full scope of Iran’s nuclear capabilities is the agency’s highest priority. On December 3, 2026, the IAEA Board of Governors passed a resolution—supported by the United States—demanding that Iran provide a full accounting of its nuclear stockpiles and grant inspectors immediate access. This resolution serves as a formal international requirement for transparency, regardless of the status of bilateral U.S.-Iran negotiations.

Monitor IAEA Board of Governors meeting minutes for the most reliable updates on inspector access, as these documents are the primary record of verified compliance.
