据五名熟悉美国情报情况的消息人士透露，近几周来伊朗大幅加强了对其近武器级铀储备的封存工作，故意炸毁隧道并在入口处布设诡雷。
消息人士称，相较于仅一个月前，如今获取约半吨高浓缩铀的难度、危险性和耗时都大幅增加。当时美国总统唐纳德·特朗普曾公开暗示，他可能下令美军夺取这批铀材料。
伊朗新增的防御工事，进一步增加了特朗普政府拟与德黑兰达成的移除并销毁铀材料协议的复杂性，此举也引发了谁将承担危险的挖掘工作的疑问。
伊朗驻联合国代表团未立即回复置评请求，白宫也未立即回应CNN的提问。
特朗普多次表示，在当前为结束战争、重新开放伊朗实际已封锁的霍尔木兹海峡而进行的谈判中，确保这批材料的安全是美国的优先事项。
据一名周五向记者通报情况的高级政府官员透露，双方正逐渐接近一项协议，该协议将要求伊朗将其浓缩铀移交给美国。该官员表示，这批铀将在原地销毁，随后运出该国。
但美伊官员对这项 tentative 协议的说法存在分歧，其具体条款仍不明确。一份据称是协议草案的文本于周五泄露给伊朗一家半官方新闻机构，引发特朗普在社交媒体上愤怒抨击。
多名消息人士称，即便对伊朗自身而言，移除这批浓缩铀如今也困难且危险。这需要重型挖掘设备和排雷行动——这些工作既困难又充满风险。
“如果这篇报道属实，那无疑会使……回收高浓缩铀的工作复杂化，”斯科特·罗克说道。他于2017年至2021年担任美国国家核安全管理局核材料移除办公室主任。
这也可能为伊朗掩盖其遵守协议的努力提供机会。
罗克表示，如果谈判代表“要求伊朗将全部储备运往中央地点进行核查，并最终移除或稀释这批材料”，那么责任将落在德黑兰身上，由其负责获取并“提供浓缩铀的完整清单”。
但他说：“在这种情况下，我担心伊朗会声称部分高浓缩铀无法回收。我们无法完全确信伊朗未来某个时候不会重新获取这批材料。”
国际社会认为，这批储备中的大部分位于伊朗中部伊斯法罕核设施的坍塌隧道中，另有部分材料存放在其他地点。
CNN此前曾报道，5月中旬美军曾准备开展一项夺取核材料的行动，但最终被认定风险过高而取消。
但自那以后，伊朗进一步加强了据称埋藏着其高浓缩铀的地下地点的防御。
特朗普此前曾承认武力回收铀材料的危险性，并在5月做客福克斯新闻时表示，他怀疑伊朗能否在不被美国情报机构发现的情况下，获取并取回被掩埋的核材料。
“我们完全清楚那里的情况，”特朗普在接受福克斯新闻主持人肖恩·汉尼提采访时谈及该设施时说道，“没人甚至接近过它。”
但两名消息人士指出，总统公开将这批铀列为可能的打击目标，可能促使伊朗更好地保卫其资产。
如今，即便德黑兰与华盛顿在未来几周内签署协议，预计双方还需进行额外的技术谈判，以敲定伊朗核计划未来的细节。
从该国移除铀材料可能需要部署由田纳西州橡树岭国家实验室美国国家核安全管理局组织的专用移动式铀处理设施。CNN此前曾报道，美国高级谈判代表贾里德·库什纳和史蒂夫·维特科夫于本月早些时候访问了该实验室。
但即便是全球顶尖的核材料移除专家，也需要大量时间才能完成任务——特朗普本月早些时候告诉记者，移除工作至少需要两周时间。

Exclusive: Iran sealed uranium cache and placed mines amid fears of US operation to seize material
2026-06-13T04:00:07.952Z / CNN
- Iran has escalated efforts to seal off its cache of near bomb-grade uranium, collapsing tunnels and planting explosive mines at entrances, according to five sources familiar with US intelligence.
- The fortifications make retrieval far more difficult and dangerous, complicating Trump administration negotiations for a deal to remove the material.
- Even Iran itself would now need heavy excavation equipment and de-mining efforts to access the roughly half-ton stockpile.
AI-generated summary was reviewed by a CNN editor.
In recent weeks, Iran has dramatically escalated efforts to seal off its cache of near bomb-grade uranium, deliberately collapsing tunnels and booby-trapping entrances with explosive mines, according to five sources familiar with US intelligence.
Getting to the roughly half-a-ton of highly-enriched uranium is now far more difficult, dangerous and time-consuming than it already was just a month ago, when President Donald Trump was publicly signaling that he might order the US military to seize it, the sources said.
The new fortifications by the Iranians add an additional layer of complexity to the Trump administration’s proposed deal with Tehran to remove and destroy its uranium, and the move raises questions about who will take on the dangerous task of digging it out.
Iran’s diplomatic delegation to the United Nations did not immediately return a request for comment, and the White House did not immediately reply to questions from CNN.
Trump has repeatedly stated that securing the material is a priority for the US in the ongoing negotiations to end the war and re-open the Strait of Hormuz, which Iran has effectively closed.
And according to a senior administration official who briefed reporters Friday, the two sides are inching closer to a deal that would require Iran to turn its enriched uranium over to the US. It would be destroyed on site and then taken out of the country, according to that official.
But US and Iranian officials have offered conflicting accounts of the tentative deal, and its precise terms remain unclear. The purported text of a draft deal leaked to a semi-official Iranian news agency Friday, triggering an angry outburst from Trump on social media.
Even for the Iranians themselves, several of the sources said, removing the enriched material would now be difficult and dangerous. It would require heavy excavation equipment and de-mining efforts — which are difficult and risky.
“If this reporting is true, it would definitely complicate … retriev[ing] the HEU,” said Scott Roecker, who headed the National Nuclear Security Administration’s Office of Nuclear Material Removal from 2017 to 2021.
It could also offer an opportunity for Iran to obfuscate its compliance efforts.
If negotiators “require that Iran bring the entire stockpile to a central location for verification and ultimately to remove or downblend the material,” that would place the onus on Tehran to access and “provide the full inventory” of enriched uranium, Roecker said.
But, “in this scenario, I would worry that Iran would claim that some portion of the HEU was irretrievable,” Roecker said. “We wouldn’t have full confidence that Iran couldn’t retain access to it at some point in the future.”
The international community believes most of the stockpile is in collapsed tunnels at the Isfahan nuclear complex in central Iran, with some additional material held at other sites.
In mid-May, the military was prepared to conduct an operation to seize the nuclear material that was ultimately deemed to be too high-risk, CNN has previously reported.
But in the time since then, Iran has only further fortified the sites where its highly enriched uranium is believed to be buried underground.
Trump has previously acknowledged the dangerous nature of retrieving the uranium by force, and he expressed skepticism in a May appearance on Fox News that the Iranians would ever be capable of accessing and retrieving the buried nuclear material without detection from US intelligence.
“We know exactly what’s happening,” Trump told Fox host Sean Hannity of the site. “Nobody’s even gotten close to it.”
But by publicly discussing the uranium as a possible target, two of the sources noted, the president may have provided Iran with the impetus to better defend its own assets.
Now, even if the agreement between Tehran and Washington is signed in the coming week, additional technical negotiations to hammer out the details on the future of Iran’s nuclear program are expected.
Removing the uranium from the country would likely require the deployment of a specialized mobile uranium facility organized under the National Nuclear Security Administration at Oak Ridge National Laboratory, Tennessee. CNN previously reported that top US negotiators Jared Kushner and Steve Witkoff visited the laboratory earlier this month.
But even the world’s top nuclear removal experts would need significant time to complete their task — Trump told reporters earlier this month that removal would take at least two weeks to complete.
