Nuclear power is produced by harnessing the heat produced by the splitting of atoms inside uranium - a process known as fission.

核能是由原子内的铀发生链式反应而释放的能量——这个过程叫做裂变。

So what is it that we're ultimately trying to do in nuclear power? We want to make and capture the heat from the fission process.

所以，那就是我们最后要尝试的，在核能方面的，我们要创造，并捕获热量，从裂变过程中。

That's due to the heat that remains in the nuclear core, both from the recently-disabled but still-hot fuel rods and from the various byproducts of the fission process.

燃料棒虽然停止工作，但仍然非常炙热，而且裂变反应生成的多种副产物也会产生很多热量，这些热量一直维持在反应堆的核心。
