Weapons grade uranium is 90%. Bethany Bell reports.

武器级浓缩铀的纯度为 90%。贝瑟妮·贝尔报道。

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。

That is far below the 90-percent required for weapons grade uranium.

这远低于武器级铀所需的 90%。

American officials say Iran will dilute or weaken its near weapons grade uranium so it can not be used in weapons.

美国官员表示，伊朗应该稀释或减弱其接近武器级别的浓缩铀，这样就不能用于生产核武器。

Because while there are still technical challenges to going even higher, once you hit 20 you're well on the way to weapons grade enrichment.

因为尽管仍然存在更高的技术挑战，但一旦达到 20%，你只要进行装备升级就稳了。

The UN's nuclear watchdog, the International Atomic Energy Agency said in its August report, that Iran was continuing to enrich uranium up to 60% Purity short of 90% weapons grade fuel.

联合国的核监督机构国际原子能机构在8月份的报告中说，伊朗继续进行纯度高达60%的铀浓缩，纯度低于90%的武器级燃料。

In exchange, Iran agreed to halt enrichment of uranium above five percent, well below weapons grade and to dilute or convert its current stockpile of enriched uranium so it cannot be used for a weapon.

而作为交换, 伊朗同意停止对于百分之五以上的铀浓缩, 这远低于武器级别而且稀释或转换当前的浓缩铀库存, 这样就不能用于武器用途。
