But, because the tsunami damaged the diesel-powered generators that pumped the water, the core kept heating up.
但是，因为海啸破坏了吸水的电力发电机，核心不断放热。
2 hr 15 min Water no longer covers the top of the core.
2小时15分钟堆芯的上部已经露出水面。
That was just enough water to keep that core, and that may have been the Browns Ferry event as I remember, I'll check again.
那些水足够能保持核心，那可能是在Browns，Ferry事故中,我记得的，我会在查一下。
The bottom of core recovery which means water will get back to the bottom core in about forty seconds, the core is now uncovered.
核心回收率的底部,意思是水会回到核心的地步,在40秒之内，核心现在已经没有覆盖的了。
If the water stops flowing, there is a problem. The core overheats and more of the water turns to steam.
BBC的Richard Black解释道：“如果水停止流动，那么这将会造成这样一个问题：核心部件会过热导致水气化成蒸气，而蒸气将会导致内部巨大的压力。
When you have an event, the reactor is operating at full power, you blowdown the primary coolant which is hot, you start injecting emergency core cooling water which is cold.
当你进行的时候，反应堆就会用全部的动力，运行，你排放出初冷却剂，那是热的，你开始注入紧急核心冷却水，那是冷的。

这些燃料棒就是反应堆的核心，它位于水中，并包裹在厚厚的钢制压力容器中。
A nuclear reactor produces electricity by heating up the radioactive material in its core, which then heats water to produce steam. That steam is used to turn turbines that produce electricity.
核反应堆通过加热堆心的放射性物质产生电力，然后用这些电力加热水产生蒸汽，再用蒸汽驱动涡轮发电机发电。
But even after shutdown, there is residual heat that needs to be drawn off by cooling water pumped through the reactor core, and that’s where the trouble came.
