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.
核项目中技术难题是生产核反应堆的燃料。
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.
法国的竞标团队也能提供全套服务：Areva提供燃料，处理生产废料并负责反应堆设计；而EDF则负责核电站的运作。
It too could offer full service, in that Areva supplies fuel and manages waste in addition to designing reactors, while EDF runs more nuclear plants than any other firm.
此外虽然日本与俄罗斯的双边关系充满荆棘，但也未能阻止东芝公司与俄罗斯国有Atomenergoprom公司（“原子能电力公司”）就合作进行反应堆建造与铀燃料生产达成一致。
Japan's prickly relations with Russia did not stop Toshiba agreeing on joint reactor-construction and fuel-production efforts with state-owned Atomenergoprom.
最早为生产用的反应堆，必须使用普通铀作为燃料。
The earliest production reactors necessarily used normal uranium as fuel.
