Well, these reactors are huge machines, and the nuclear material sits inside a thick metal pressure vessel known as its containment.

这反应堆是巨大的机器，核材料置于一个厚厚的金属压力容器中，称为安全壳。

These arteries are really more like a balloons — they're pressure reservoirs, able to expand and recoil with every heartbeat.

这实际上更像一个气球——它们是压力容器，能够随着每一心跳而膨胀和后退。

This is a representation of this pressure vessel - was not punctured.

这是该压力容器的示意——刺穿。

For example, this tank here that holds the water doubles as the pressure container.

例如，这里的水箱不仅用于盛水，还兼作压力容器。

So if we're talking light water reactors, which is probably the most common kind of power reactor around, you then have this very large pressurised tank, which is the reactor pressure vessel.

所以如果我们谈论的是轻水反应堆，这可能是最常见的发电反应堆类型，那么你就有了这个非常大的加压罐，也就是反应堆压力容器。

The best thing to do to cut up and carry away a reactor pressure vessel is to wait 50 years, if you can.

处理反应堆压力容器的最佳方法是，如果可能的话，等待50年。

And so if we're talking decommissioning of this reactor pressure vessel, you really have to wait for a while.

因此， 在讨论拆除这个反应堆压力容器时，确实需要等待一段时间。

And so the core of the reactor sits in this big pressure cooker and it's a tank full of water.

反应堆的核心就位于这个巨大的压力容器中，里面装满了水。
