Construction accounts for as much as three-quarters of the cost of nuclear generation, since fuel and other operating costs are relatively low.

由于核电厂的燃料和其他运作成本相对较低，建造成本相当于核能发电成本的四分之三。

However, reprocessing is controversial because the extracted plutonium can be used to produce nuclear weapons. It also costs substantially more than using fuel once and then storing it as waste.

同时相比放射性燃料的一次性使用（即用完就作为核废料填埋），循环利用核燃料会大大增加成本。
