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.
然后，更重要的是要密切监视生产这种危险燃料的核工厂，特别是进行铀浓缩和从废料中分离钚的那些地方。
All the more important, then, to keep a close eye on plants that produce quantities of such dangerous materials-especially where uranium is enriched and plutonium is extracted from spent fuel.
多年来，科学家也已经尝试着象工厂生产产品那样做，用阳光给燃料做光合作用。
