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

这些反应堆是巨大机，核材料被置于一个厚厚金属压力中，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.

这些动脉实际一个气球——它们是压力，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.

这是该压力示意图——未被刺穿。

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

例如，这里水箱不仅用于盛水，还兼作压力。

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.

所以如果我们谈论是轻水反应堆，这可能是最常见发电反应堆类型，那么你就有了这个非常大加压罐，也就是反应堆压力。

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

处理反应堆压力最佳方法是，如果可能话，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.

反应堆核心就位于这个巨大压力中，里面装满了水。
