核能是通过铀这种大量开采的矿石金属生成的。加拿大、澳大利亚和哈萨克斯坦占据了全球超过半数的供应量。

Nuclear power is generated using uranium, a metal that is mined as an ore in large quantities, with Canada, Australia and Kazakhstan providing more than half of the world's supplies.

气体反应堆要求充实，以此能，达到20%，所以，我们需要制造出在芯块中的铀，那是锆管道的金属外壳，那被放置入一个反应堆核心里去。

Gas reactors require enrichments in the order of up to 20%. So we need to fabricate the uranium into pellets which are clad in zirconium tubes which are placed into the reactor core.

但是他说，核能对中国来说并不是一个长远的解决办法，因为全世界金属铀的储藏量有限，而且如何妥善处理核废料也是一个难题。

But he says nuclear power is not a long-term solution for China's energy needs because the world's uranium stores are limited and it is difficult to properly dispose of nuclear waste.
