内贾德这周提出接受西方的方案，并用低浓缩铀交换反应堆所用的燃料。
Ahmadinejad this week offered to take the West's deal and trade it for fuel for its reactor.
伊朗是迄今为止唯一的、在尚未拥有哪怕一座需要以本国铀元素充当堆芯燃料的已运作反应堆之前却已建成铀浓缩工厂的国家。
Iran is the only country so far to have built a uranium-enrichment plant before having even a single working reactor that would need its uranium as fuel for the reactor core.
这表明伊朗的浓缩计划将进一步升级，民用只不过是为反应堆提供燃料的一个借口。
It marked an aggressive escalation in Iran's enrichment programme and its only civilian pretext to fuel the reactor.
伊朗坚决拒绝停止浓缩铀项目，它说该项目是为了给民用反应堆提供燃料，而西方国家和其他国家怀疑这是掩盖制造核武器的借口。
Iran has steadfastly refused to halt its nuclear-enrichment programme, which it says is to make fuel for civil reactors but which the West and others suspect is a cover to develop nuclear weapons.
科学家一直在寻找更简单的方法制造名为浓缩铀的昂贵材料- - - - - -核反应堆和炸弹的燃料，现在只在大型工厂生产。
Scientists have long sought easier ways to make the costly material known as enriched uranium - the fuel of nuclear reactors and bombs, now produced only in giant industrial plants.
伊朗须承诺不在其它地方进行铀浓缩并接受检查；由IAEA运营的工厂将为伊朗和本地区其它国家的反应堆制造足够燃料。
Iran would have to promise not to enrich anywhere else, and accept inspections; the IAEA-operated plant would then make enough fuel for Iranian reactors and those in the rest of the region.
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 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.
呼吁以高浓缩铀作为核反应堆燃料的国家改用低浓缩铀。
It called on states with reactors burning high-enriched uranium to switch to the low-enriched sort.
邦教授提到目前全世界大约有130个利用高浓缩铀作为燃料的反应堆。
Professor Bunn says there are currently about 130 research reactors around the world that still use highly enriched uranium for fuel.
为将燃料做成电能反应堆，铀被浓缩至U-235同位素含量5%以下。
To make fuel for electricity-generating reactors, uranium is enriched to less than 5 percent of the isotope U-235.
没有任何其他国家在没有反应堆来利用其产品的情况下就建造了铀浓缩设备；伊朗人在Bushehr的建造一旦接近完工就会利用来自俄罗斯的燃料来运行。
No other country has built a uranium-enrichment plant without having a working reactor to use the stuff; the Iranian one nearing completion at Bushehr will run on Russian fuel.
伊朗星期三表示，伊朗安装了用于铀浓缩的新一代离心机，并在德黑兰的研究反应堆中首次安装了国产核燃料棒。
Iran said Wednesday it had installed a new generation of centrifuges to enrich uranium, and for the first time loaded domestically produced nuclear fuel into Tehran's research reactor.
按照这两个国家的计划，伊朗将把一些浓缩铀运往土耳其，换取伊朗医疗研究反应堆所需的燃料。
Under the two countries' plan, Iran would send some of its uranium to Turkey in exchange for fuel for use in a Tehran medical research reactor.
其燃料需要浓缩至将近20%（动力反应堆只需3.5%就能运转）。
The fuel needs enriching to just under 20% (power reactors run on only 3.5%).
其燃料需要浓缩至将近20%（动力反应堆只需3.5%就能运转）。
