That moment never came, despite total spending of more than $2 billion on fuel oil and the aborted light-water reactors.

尽管已经花费总计20多亿美元的燃油又将一座废弃的轻水反应堆扔在那里，但是朝方兑现诺言的那一刻也永远不会来临。

Enrichment as you know is an important step for light water reactors. We have to take 0.7% uranium two thirty five ore and enrich it to 4 or 5% for fuel to be used in thermal light water reactors.

改进如你们所知，是一个很重要的步骤,对于轻水反应堆,70的矿物药是4到5%的燃料,然后用于热轻水反应堆。
