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.
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。
It's true that the nuclear enrichment and reprocessing facilities used to produce fuel for peaceful reactors can just as easily be used to make fissile material for bombs.
用于和平建设目的的核反应堆所需要的铀浓缩与后处理设施同样可容易地用于制造核武器所需的裂变材料。
As a light water nuclear reactor fuel cladding material, Zr alloy has been wide used and its application experience accumulated, hence it is the potential materials for SCWR.
锆合金作为轻水核反应堆燃料元件的包壳材料已得到了广泛的应用并积累了丰富的经验，因而仍被列为SCWR潜在的应用材料。
Enrichment can produce either fuel for a nuclear reactor or material for a warhead - but tens of thousands of centrifuges are needed to do either on a large scale.
丰富也能生产对于一个核子反应炉加燃料或对于一个弹头是物质的生产-但是在大的刻度上也做需要数万离心分离机。
