reactor shut down的意思|示意

In modern nuclear reactor designs, pumps aren't necessary to move water through the core in an emergency shut down.

在现代的核反应器设计中，当紧急措施关闭时水泵没有必要将水通过核心抽上来。

Because the reactor had been shut down a long time ago, the decay heat had decreased to a significantly lower level, so the pressure in the plant stabilized, and venting was no longer required.

因为反应器已经关闭了很长时间，残余热量下降到了一个显著的低水平，因此工厂内部的压力已经稳定，不再需要继续排气。

So you have all these trips to put in place that will allow you to shut the reactor down which is the most important thing in managing a significant accident.

所以，你们会得到这些所有的差错，那会使你们将反应堆停止，那是最重要的一件事，在处理一个重要的事故中。

When a reactor core is shut down, its energy output drops not to zero, but about 6% of its normal output, Forsberg told me.

当一个反应器的中心部位被关掉，它的能量输出到零，但是6%仍然正常输出，forsberg说。

The control rods are also used to shut the reactor down from 100% power to about 7% power (residual or decay heat).

它也用来关闭反应器，可以从100%的动力降到7%动力（残留的延迟的热量造成）。

Meanwhile in May 2009, the Chalk River reactor started leaking heavy water and was again shut down.

也是在2009年5月，乔克里弗反应堆开始出现重水泄露现象，被迫再次关闭。
