Nuclear reactors work in a similar way to other power plants, but instead of using coal or gas to generate heat, they use nuclear fission reactions.

核反应堆的工作原理和其他的发电站很相似，不过它们并不是使用煤炭或煤气来生成热量，而是利用核裂变反应。

Until fusion power plants are built, accelerators can be used to clean up the fission ones.

在核聚变发电厂建成之前，加速器还可以用来清理核裂变。

These radioactive elements are by-products of the fission reaction that generates power in the nuclear plants.

这些放射性元素为核电站裂变发电时的副产品。

Since China and India will be industrialising heavily this century, there is no other option but to consider nuclear fission power plants for electricity generation.

The fission-reactor designs of the start-ups are very different from the existing plants and even from the advanced designs put out by the established players.
