联合国核监督机构负责人表示，伊朗的浓缩铀储备基本未受影响，其核基础设施（其中大部分深埋地下）无法通过空袭完全摧毁，这凸显了军事行动的局限性。
周三，联合国核监督机构负责人向记者暗示，伊朗的核计划不太可能通过军事力量消除，他警告称持续的美以打击无法完全瓦解德黑兰的核能力。
当被直接问及该计划是否可以通过军事手段解决时，国际原子能机构总干事拉斐尔·格罗西表示，他认为这不可能。
“这个计划非常庞大，”格罗西说，描述了数十年来建立的由建筑、专业知识和基础设施构成的网络。“最终……材料和浓缩能力仍然存在。
“我们将不得不回到某种形式的谈判。”
格罗西强调，他不提供军事建议，他的评论是对该计划规模的技术评估。
这位核检查员表示，该机构的评估显示，伊朗的浓缩铀储备基本保持在打击前的位置，大部分材料被认为位于伊斯法罕核设施，较小部分在纳坦兹。

“我们的假设是，这些材料……还在原地，”他说。
这一现实凸显了一个更广泛的挑战。伊朗大部分最敏感的核基础设施——包括浓缩铀储存设施——都深埋地下，仅靠空袭难以摧毁。
尽管美以打击已经削弱了伊朗核计划的部分内容，包括地面设施和支持基础设施，但尚未消除该计划的核心组成部分。
这一评估与之前关于对伊朗核计划采取军事行动局限性的报道一致。分析师表示，储存在伊斯法罕等地的高浓缩铀被认为存放在相对可移动的容器中，埋于地下深处，若无法直接进入设施，将难以摧毁或确保安全。

“甚至美国都不清楚所有铀的位置，”军备控制协会不扩散政策主任凯尔西·达文波特此前曾告诉福克斯新闻数字频道，他指出储存容器的可移动性增加了部分材料可能被转移或分散的可能性。
根据国际原子能机构的数据，截至2025年年中，伊朗拥有约441公斤丰度为60%的铀，如果进一步浓缩，足以制造多枚核武器。
专家估计，在理想条件下，武器级浓缩的最后一步可能需要数周时间，尽管制造可交付使用的武器还需要额外时间进行武器化和交付系统整合。
格罗西还指出，伊斯法罕附近一个新披露的浓缩设施周围仍存在不确定性。

该地点被认为是一个新宣布的地下浓缩设施，伊朗可能在此安装离心机生产浓缩铀。格罗西表示，国际原子能机构尚未对该地点进行检查，也不清楚其是否在运行、建设中或配备核材料。
“我们知道它在哪里……但我们无法进入，”他说。
格罗西表示，冲突期间，该机构无法进入一些地点，部分依赖图像评估状况。
这种监测缺口凸显了当前监督的局限性。格罗西承认，该机构对伊朗核计划的某些部分缺乏全面了解，特别是那些无法检查的地点。

IAEA chief says Iran’s nuclear program can’t be eliminated by strikes | Fox News

The United Nations’ nuclear watchdog chief says Iran’s enriched uranium stockpiles remain largely in place and its nuclear infrastructure — much of it buried deep underground — cannot be fully eliminated by airstrikes, underscoring the limits of military action.
The head of the United Nations’ nuclear watchdog suggested to reporters Wednesday that Iran’s nuclear program is unlikely to be eliminated through military force, warning that ongoing U.S. and Israeli strikes cannot fully dismantle Tehran’s capabilities.
Asked directly whether the program could be resolved militarily, International Atomic Energy Agency Director General Rafael Grossi said he did not believe it could.
“This program is a very vast program,” Grossi said, describing a network of buildings, expertise and infrastructure built over decades. “At the end of this … the material will still be there, the enrichment capacities will be there.
“We will have to go back to some form of negotiation.”
Grossi emphasized he does not offer military advice, framing his comments as a technical assessment of the program’s scope.
The nuclear inspector said the agency’s assessment is that Iran’s enriched uranium stockpile remains largely where it was prior to the strikes, with most of the material believed to be at the Isfahan nuclear complex and smaller amounts at Natanz.

“Our assumption is that the material is … where it was,” he said.
That reality underscores a broader challenge. Much of Iran’s most sensitive nuclear infrastructure — including storage sites for enriched uranium — is buried deep underground, making it difficult to destroy through airstrikes alone.
While U.S. and Israeli strikes have degraded parts of Iran’s nuclear program, including above-ground facilities and support infrastructure, they have not eliminated the core components of the program.
That assessment aligns with previous reporting on the limits of military action against Iran’s nuclear program. Analysts say highly enriched uranium stored at sites like Isfahan is believed to be kept deep underground in relatively mobile containers, making it difficult to destroy or secure without direct access to the facilities.

“It’s not even clear the United States knows where all of the uranium is,” Kelsey Davenport, director of nonproliferation policy at the Arms Control Association, previously told Fox News Digital, noting that the mobility of storage containers raises the possibility that some material could be moved or dispersed.
Iran possessed roughly 441 kilograms of uranium enriched to 60% as of mid-2025, enough, if further enriched, to fuel multiple nuclear weapons, according to the International Atomic Energy Agency.
Experts estimate the final step to weapons-grade enrichment could take weeks under ideal conditions, though building a deliverable weapon would require additional time for weaponization and delivery systems.
Grossi also pointed to continued uncertainty surrounding a newly disclosed enrichment facility near Isfahan.

The site is believed to be a newly declared underground enrichment facility where Iran could potentially install centrifuges to produce enriched uranium. Grossi said the International Atomic Energy Agency has not yet inspected the location and does not know whether it is operational, under construction or equipped with nuclear material.
“We know where it is … but we have not been able to go,” he said.
Grossi said the agency has not been able to access some sites during the conflict and is relying in part on imagery to assess conditions.
The gaps in access highlight the limits of current monitoring. Grossi acknowledged the agency lacks full visibility into some parts of Iran’s program, particularly sites it has not been able to inspect.
