This system is used to pump water into the core, low pressure safety injection and high pressure safety injection.

这个系统是用来将水抽到核心里去，降低压力安全加入和高压力，安全加入。

And we have, if you will, a low pressure injection system that will also provide water into the core for low pressure. And we have boron that's capable of being inserted as well, as needed.

如果你们可以，一个低压力的加入系统，会给低压力的核心提供水，我们还有硼，它也是可以，被加入的，也是需要的。

Thought water is a good refrigerant, it is difficult to be used directly in a common compression refrigeration system due to its very low pressure and vapor density at the evaporation temperature.

由于水的蒸发压力低、比容大使得水作为制冷剂直接用于压缩式制冷系统还有很大的困难。
