Three family groups shared a storage facility for spent nuclear fuel, the scientists found.

科学家们发现，三个家族群体共用一个乏燃料储存设施。

The Finnish government approved construction of the deep-underground repository in 2015, to safely dispose of spent nuclear fuel.

芬兰政府于2015年批准建造深地下储存库，以安全处理乏燃料。

This large pool of water is meant to cool spent fuel rods after they come out of a nuclear reactor.

这一大池子水原本是用来冷却用过的燃料棒，而燃料棒则是从核反应堆中取出的。

Nuclear power takes uranium mines, facilities to refine the uranium, a reactor, and a place to store the spent fuel safely.

核能需要铀矿、提炼铀的设施、反应堆和安全储存乏燃料的地方。

Both the primary and backup power sources failed so the pumps and cooling systems for the spent fuel pools couldn't run leaving the water to heat up.

主电源和备用电源都发生故障，因此乏燃料池的泵和冷却系统无法运行，导致水升温。

Every one to two years, some spent fuel is removed from reactors and stored in pools of water that cool the waste and block its radioactive emissions.

每过一两年，一些用完的燃料就会被从反应堆中提走，然后储存在废水池中来冷却这些残渣和隔绝辐射。

Usually these pools are physically inside the nuclear power plants so, when spent fuel is removed from the reactor, it's put directly into the water and left there.

而这些水池位于核电站内部， 因此，当乏燃料从反应堆中移除后，会直接存放到水中。

American companies can only transfer nuclear technology to a country that has signed an agreement that rules out domestic uranium enrichment and the preprocessing of spent nuclear fuel.

美国公司只能将核技术转让给签署了“排除在国内进行铀浓缩和废核燃料处理”协议的国家。
