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

些反应是巨大的机器，核材料被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.

些动脉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.

是该压力容器的示意图——未被刺穿。

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

例如，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，能是最常见的发电反应类型，那么你就有了个非常大的加压罐，也就是反应压力容器。

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

处理反应压力容器的最佳方法是，如果能的话，等待50。

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

因此， 在讨论拆除个反应压力容器时，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.

反应的核心就位于个巨大的压力容器中，里面装满了水。
