IAEA Believes It Knows Where Iran's Buried Uranium Is

Why It Matters

Locating and securing Iran’s hidden uranium is crucial for preventing nuclear proliferation and shaping the future of the Iran nuclear negotiations.

Key Takeaways

• IAEA says most uranium remains at Esfahan nuclear site.
• Small quantities may exist above ground at Natanz facility.
• Verification hinges on inspector access and satellite imagery confirmation.
• Negotiators consider shipping, down‑blending, or third‑party storage options.
• Regional proliferation worries rise amid Iran and North Korea developments.

Summary

The International Atomic Energy Agency (IAEA) asserts that the bulk of Iran’s concealed uranium stockpile resides in the Esfahan nuclear complex, a site hit during last year’s 12‑day conflict. While the agency acknowledges the possibility of limited above‑ground material at the Natanz plant, it emphasizes that the overall quantity is modest and remains under Iranian control.

Satellite imagery and on‑the‑ground intelligence give the IAEA confidence in its assessment, but the agency stresses that verification requires unrestricted inspector access. Without a cease‑fire or a negotiated agreement, inspectors cannot confirm that the material is not being diverted, prompting calls for a transparent, verifiable framework.

Officials involved in the diplomatic track, including U.S. envoy Steve Wyckoff and former adviser Jared Kushner, have discussed potential “off‑ramps” such as shipping the uranium to a third‑party state, down‑blending it, or other disposition methods. The conversation reflects broader concerns about nuclear proliferation, drawing parallels to North Korea’s accelerating weapons program and past crises in Iraq, Syria, and Libya.

If a verifiable solution is reached, it could restore confidence in the Iran nuclear deal and set a precedent for handling concealed nuclear material worldwide. Failure to secure such an agreement risks reigniting regional tensions and encouraging other states to pursue similar clandestine programs.

Original Description

International Atomic Energy Agency Director General Rafael Mariano Grossi says it's believed that Iran's uranium stockpile remains buried at Isfahan. He says as part of any deal, inspectors must be allowed to verify Iran's claims. He speaks on "Bloomberg Surveillance."
