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。

Spraying water on storage pools full of overheating spent uranium fuel rods is not very effective because rising steam dissipates much of the incoming water.

向装有过热铀燃料棒的储存池里撒水效率不高，上升的蒸汽驱散了大量水分。

The pool cooling water must be continuously circulated. Without circulation, the still thermally hot irradiated nuclear fuel in the storage pools will begin to boil off the cooling water.

池中的冷水必须连续循环，如果不循环的话，贮存池中非常热地热放射性核燃料就会将冷水烧沸。

Tepco fears some of the fuel rods may become exposed if the water in their storage pools is allowed to boil down too low.
