Iran upped near weapons-grade uranium stock before Israel attack: IAEA

VIENNA — A confidential report by the United Nations’ nuclear watchdog circulated to member states and seen by The Associated Press said Wednesday that Iran increased its stockpile of uranium enriched to near weapons-grade levels before Israel launched its military attack on June 13.

The report by the Vienna-based International Atomic Energy Agency said that as of June 13, Iran had 440.9 kilograms (972 pounds) of uranium enriched up to 60%, an increase of 32.3 kilograms (71.2 pounds) since the IAEA’s last report in May.

The report stated that this figure is “based on the information provided by Iran, agency verification activities between 17 May 2025 and 12 June 2025 (the day preceding the start of the military attacks), and estimates based on the past operation of the relevant facilities.”

That material is a short, technical step away from weapons-grade levels of 90%.

The confidential report also said Iran and the IAEA have not reached an agreement on resuming inspections of sites affected by Israeli and U.S. bombing in June.

The only site inspected since the war has been the Bushehr Nuclear Power Plant, which operates with Russian technical assistance.

The director general of the U.N. nuclear watchdog, Rafael Grossi, said that “technical modalities to enable the full resumption of Agency inspection should be concluded without delay,” the report stated.

The report stated that while the withdrawal of UN inspectors from Iran during the war “was necessary given the overall security situation, Tehran’s “subsequent decision to cut cooperation with the IAEA was ”deeply regrettable."

As of June 13, Iran’s total enriched uranium stockpile was 9874.9 kilograms, which represents an increase of 627.3 kilograms since the last repot in May, the report said.

The IAEA said that since June 13, it has “not been able to conduct the in-field activities required to collect and verify Iran’s declarations used to estimate the changes to the previously reported stockpile.”

According to the IAEA, approximately 42 kilograms of 60% enriched uranium is theoretically enough to produce one atomic bomb, if enriched further to 90%.

The IAEA also reported that inspectors have not been able to verify Iran’s near bomb-grade stockpile for over two and a half months, which it called “a matter of serious concern.”

维也纳——联合国核监督机构向成员国分发的一份机密报告（美联社周三看到）称，在以色列于6月13日发动军事袭击之前，伊朗将其浓缩铀库存增加到接近武器级水平。

总部位于维也纳的国际原子能机构的报告称，截至 6 月 13 日，伊朗拥有 440.9 公斤（972 磅）浓缩度高达 60% 的铀，比国际原子能机构 5 月份的上一份报告增加了 32.3 公斤（71.2 磅）。

报告指出，这一数字“基于伊朗提供的信息、2025 年 5 月 17 日至 2025 年 6 月 12 日（军事袭击开始的前一天）期间的机构核查活动，以及根据相关设施过去的运行情况做出的估计”。

这种材料距离武器级90%的水平只差一步之遥。

该机密报告还指出，伊朗和国际原子能机构尚未就恢复对6月份以色列和美国轰炸影响地区的核查达成协议。

战后唯一接受检查的地点是布什尔核电站，该电站由俄罗斯提供技术援助。

报告指出，联合国核监督机构总干事拉斐尔·格罗西表示，“应立即完成使该机构全面恢复核查的技术方案”。

报告指出，虽然鉴于整体安全形势，联合国核查人员在战争期间撤出伊朗是“必要的”，但德黑兰随后决定切断与国际原子能机构的合作“令人深感遗憾”。

报告称，截至6月13日，伊朗浓缩铀库存总量为9874.9公斤，比5月份的上次报告增加了627.3公斤。

国际原子能机构表示，自 6 月 13 日以来，它“一直无法开展收集和核实伊朗申报信息所需的现场活动，而这些信息用于估算先前报告的库存变化”。

根据国际原子能机构的说法，理论上，大约 42 公斤 60% 浓缩铀足以制造一枚原子弹，如果进一步浓缩到 90% 的话。

国际原子能机构还报告称，核查人员已经两个半月多未能核实伊朗接近炸弹级别的库存，该机构称这是“一个令人严重关切的问题”。
