Instead, spent fuel rods in the U.S. are currently stored in underground pools of water or in dry-cask storage, where older fuel is put into steel cans filled with inert gas and then stored in silos.

相反，目前美国把用过的燃料棒存放在地下的水池里或装在干桶里，其中年代较远的燃料被放入充满惰性气体的钢罐里，然后存放在废弃的洲际导弹发射井中。

In the meantime, dry-cask storage can get us through the coming century, but those used fuel rods will remain a problem for at least another 9,900 years after that.

按现在情况看，干桶存储方法可以让我们安全度过下个世纪，但在以后的九千九百年里那些用过的核燃料仍然是个问题。

There have been no releases of radiation harmful to the public from this cask storage, or contamination, the NRC says.
