The tubes for the cooling rods started to melt. Workers could not put the cooling rods back into the reactor.

用来放冷却棒的管子开始熔化。工作人员无法将冷却棒重新放入反应堆中。

But the reactor cooled too quickly. So, the workers pulled the cooling rods out of the reactor.

但是反应堆冷却地速度太快了。所以工作人员将冷却棒从反应堆中撤了出来。

Not only does the water spend several decades cooling the fuel rods, but it also affects their radiation.

不仅是因为在之后的几十年里水会冷却这些燃料棒，还因为水会影响它们的辐射。
