It depends on the plant.It depends on whether it's a boiling-water reactor or a pressurized-water reactor.

这要看核电站的类型，它是沸水堆还是压水堆。

The emergency cooling system pump and motor for a boiling-water reactor are roughly the size and height of a compact hatchback car standing on its back bumper.

沸水反应堆紧急制冷系统的水泵和电动机和紧凑的两厢车竖起来的大小差不多。

The reactor that was not cooling properly in Japan, the Fukushima Daiichi No. 1 reactor, was a boiling-water type.

日本那座没有被正确冷却的反应堆，也就是福田第一电站第一反应堆，是一座沸水堆。

Now the next slide gives you a simple version of a boiling water reactor, a schematic.

现在，下一张幻灯片会给你们一个简单的，关于沸水反应堆的原理图的版本。

In a boiling water reactor like those at Fukushima, the same water that cools the reactor core also boils and drives the turbine to generate power.

在像福岛核电厂的沸水反应堆中，冷却反应堆芯的水还拿来煮沸，以此推动涡轮机旋转从而产生电量。
