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。

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。

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。

We have again the core and as you recall in a boiling water reactor the main feedwater goes into the reactor and comes out as steam and goes right to the turbine.

这里还是核心，你们记得，在一个沸水反应堆里，主要的供给水会进入到，反应堆，然后出来，变成了蒸汽，然后会直接进入涡轮。

And I wanna focus in on the boiling water reactor and the pressurised water reactor.

我想要着重在沸水反应堆，也压水式反应堆。

Daiichi's No. 1 reactor — the oldest of six boiling-water units at the site, according to the nuclear association — began commercial operation in March 1971.

Daiichi的一号反应堆——根据核子协会，6个沸水反应堆中最老的反应堆——自1971年3月开始商业运行。

At present, the pressurized water reactor and boiling water nuclear power reactor in the largest proportion.

在目前，核电站中以压水堆和沸水堆所占的比例最大。

There are several different types of nuclear reactors, including boiling water reactor systems and pressurized water reactor systems.

反应堆有很多种不同的类型，比如可以通过煮水来获得动力，也可以通过对水加压来获得动力。
