实际运行反应堆的链式反应可以在数秒左右被关闭。
The chain reaction that actually runs the reactor can be shut off in a matter of seconds.
控制棒会吸收路子减慢链式反应,降低核反应的能量释放,进而关掉反应堆。
The control rods soak up the neutrons that mediate the chain reaction which produces most of a reactor's energy, shutting it down.
乏燃料由完全耗尽铀-235的旧燃料棒组成,核反应堆的链式反应就是由铀-235激发的。
It is made up of old fuel rods that have become sufficiently depleted of uranium-235, the isotope that drives a reactor’s main chain reaction, to be no longer useful.
为使链式反应刚好能够维持下去,反应堆要有一个最起码的尺寸。(目的状语)
There is a minimum size for the reactor at which the chain reaction will just work.
