enriched uranium

基本解释

Yet he won't ship enriched-uranium fuel to Iran's all-but completed nuclear reactor while its enrichment work goes on.
但是他不会在伊朗继续进行铀浓缩活动的时候给伊朗几乎要完成的核反应堆带去浓缩铀。
The U.S. government has dismissed the proposal which calls for Iran to ship some of its low-enriched uranium to Turkey in exchange for higher-grade fuel for a medical research reactor in Tehran.
美国政府拒绝了这项建议。该建议要求伊朗将其部分低度浓缩铀运往土耳其，以换取德黑兰一医学研究核反应堆所需高等级燃料。
In particular, prompt action is needed on implementing the plan to use Iran’s own low-enriched uranium to refuel the Tehran research reactor, which is used to produce medical isotopes.
尤其必须立即采取行动，执行有关用伊朗自己提炼的低浓度浓缩铀为德黑兰作研究用的反应堆提供燃料的计划——该反应堆用于生产医用同位素。

In Washington, a military intelligence official told a Senate committee that Iran could be one year away from producing enough highly-enriched uranium for a nuclear weapon.
Tehran has not,as yet, agreed to the terms of a UN-draft deal to trade for highly enriched uranium from France and Russia.
He gave a cautious endorsement of U.S.-backed U.N.plan to handle Iran's enriched uranium.

Or it could be used secretly with more sophisticated machines quickly to turn Iran's legal stockpile of low-enriched uranium into high-enriched uranium for weapons, for example if Iran were to withdraw from the Nuclear Non-Proliferation Treaty.
