Under the new deal, Iran says it would send 1,200 kg of its stockpile of low-enriched uranium to Turkey.
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。

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.
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.
原想这是一次富有魅力的进攻，可是它取得了适得其反的效果，因为穆塔基坚称即使研究反应堆的协议通过，伊朗也会继续自行生产20%的高浓缩铀。
Intended as a charm offensive, it backfired when Mottaki insisted that even if the research reactor deal went through, Iran would continue to produce its own 20%-enriched uranium.
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.
因此，当伊朗宣称需要一套工业规模的浓缩装置，而不只是简单运转的电力级核反应堆之时，对该国的诸多担忧应运而生。
Hence the fears over Iran, which claims to need an industrial-scale enrichment plant without having a single working power reactor.
走浓缩这条路，从20%到可用作造核弹的90%的浓缩所要花费的努力甚至比艰苦地做出开始的3.5%浓度的反应堆物质要少的多。 在纳坦兹，伊朗依然在生产3.5%浓度的浓缩铀。
In the way enrichment works, getting from 20% to bomb-usable 90% enrichment takes a lot less effort even than churning out the initial 3.5% reactor-grade stuff still piling up at Natanz.
有些国家正在清除其存储的可用于制造核武的高浓缩铀和钚，有些国家正在降低核反应堆扩散的风险，还有一些国家将在会议上签署协议并支持国际原子能机构的工作。
Some are getting rid of their stocks of highly enriched uranium or plutonium, both used in bombs. Others are lowering the risk of proliferation from reactors.
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.
此外，伊朗与6国大体达成一项协定同意将部分低浓缩铀储备运送到国外提炼，用来支持德黑兰的一个研究反应堆。
An agreement in principle to ship some of Iran’s mounting stocks of low-enriched uranium abroad for further processing, to supply a research reactor in Tehran.
这些知情人士称，据另一份合同，预计Areva将向CGNPC其他拟议中的较小型核反应堆提供浓缩铀。
Under a separate contract, Areva is expected to supply uranium for other, less powerful reactors that CGNPC plans to build.
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.
