They can have highly enriched uranium, meaning weapons grade.

伊朗可以拥有等同于武器级别的高浓缩铀。

Which, sadly, he couldn't build because Santa wouldn't bring him enriched uranium.

可惜的是，他失败了，因为圣诞老人没得带给他所需的浓缩铀。

For the past two decades, however, almost 20,000 of those Russian warheads have provided highly enriched uranium.

然而在过去的20年间，约有20,000个俄国弹头为铀浓缩提供了原料。

For Iran to build a nuclear weapon it would need a stockpile of uranium enriched to weapons-grade purity.

伊朗将需要铀浓缩储备来制造高纯度武器。

They've been stockpiling low enriched uranium. They would have to give that up to go back to the deal.

伊朗一直在储存低浓度浓缩铀。他们必须放弃这一行为才能重返协议。

The International Atomic Energy Agency found uranium enriched to 84% purity, which is almost weapons-grade, at Iran's nuclear site at Fordow.

“国际原子能机构”在伊朗福尔多的核设施发现纯度为84%的浓缩铀，纯度接近武器级。

It was also now fuelling the Tehran Research Reactor-used to make medical isotopes-with its own domestically produced uranium enriched to 20%.

伊朗还正往德黑兰研究性核反应堆填充国内自主生产的纯度为20%的浓缩铀，该反应堆用于生产医用同位素。

The West is very concerned that there not be any covert program somewhere that might be able to use this enriched uranium without U.N. inspectors knowing.

西方国家非常关心是否存在联合国观察员不知情的可能使用浓缩铀的隐蔽项目。

The report by the International Atomic Energy Agency says Iran has 121.6 kilograms, or 268 pounds, of uranium enriched up to 60 percent, a far slower growth than in previous counts.

国际原子能机构的这份报告说，伊朗拥有121.6公斤（268磅）纯度为60%的浓缩铀，这一增长速度远远低于之前的统计。

And we do some more work, it turns out that what you require to make a nuclear bomb is highly enriched uranium or plutonium, which are very difficult materials to get.

我们又做了一些工作，事实证明，制造核弹需要的是高浓缩铀或钚， 这些材料很难获得。
