如果温度高到一定程度，堆心就会落到反应堆容器的底部并将其熔穿，从而到达密封装置的底部。

If the temperature is high enough, the core slumps to the bottom of the reactor vessel and melts through it and onto the floor of the containment unit.

水箱在滴水。你却不知道是因为季节产生的水汽还是密封装置坏了。

A toilet tank is dripping, and you can't tell if the water is coming from harmless seasonal sweating or a bad seal.

因此在这类情况下，系统将启动一系列的防水密封装置，即沉箱。用于安置深海停泊工具和巩固地基的吸油桩技术是这些沉箱的工作基础。

For cases like this the system will have a range of watertight structures called caissons, which are based on the suction-pile technology used to emplace deep-sea moorings and foundations.

Yes, and if we have gases involved, it's pretty similar, but now what will have is something like this. We'll have a reaction vessel that's sealed, it's constant volume.

如果涉及了气体，情况也很相似，只是现在的装置是这样的,我们有一个密封的反应容器,它的体积是恒定的。
