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。

Uranium enrichment is the process used to make fuel for nuclear power plants, but when extended it can also produce fissile material for an atomic bomb.

That material has been used to fuel nuclear plants.

It also expelled the weapons inspectors who were monitoring its plutonium-laden spent fuel rods and a reactor capable of producing more that can be reprocessed into fissile material for nuclear bombs.
