This is the same way we've been producing electricity, the steam turbine idea, for 100 years, and nuclear was a really big advancement in a way to heat the water, but you still boil water and that turns to steam and turns the turbine.
用蒸汽带动涡轮旋转，跟我们 100年来一直沿用的发电方法是一致的， 但是用核能来给水加热 却真是一个巨大的进步， 但我们仍然需要烧水，让水变成蒸汽来带动涡轮机。
