Because your fuel is liquid, and it's combined with your coolant, you could actually just drain the core into what's called a sub-critical setting, basically a tank underneath the reactor that has some neutrons absorbers.
因为燃料是液态的，并且和冷冻剂在一块儿 实际上，我们可以仅仅把堆芯中的液体 排到一个叫做亚临界的环境， 就是在反应堆下面的一个贮藏罐 里面有一些中子吸收器。
