India has since designated some of its reactors as civilian, and open to inspection, but others still churn out spent fuel richly laden with weapons-usable plutonium.
印度自那时便将其一些反应堆标明为民用，而且愿意接受检查，但其他的反应堆仍大量炮制燃烧过的富含用于武器制造的钚的燃料。
Uranium and plutonium are most likely to find their way into weapons via the enrichment and reprocessing of fuel for nuclear power plants.
铀和钚很可能通过核电厂燃料的浓缩和再加工而流向武器制造。
The United States and Russia signed an agreement to dispose of sixty-eight tons of weapons-grade plutonium. They plan to use the plutonium as fuel for civilian nuclear reactors.

In a major and welcomed development, Russia announced that it will close its last weapons-grade plutonium production reactor.
一项重大、颇受欢迎的进展是俄罗斯宣布将关闭最后一座武器级钚生产反应堆。
Much of this remains dangerous for thousands of years, and a proportion of it can be used to produce weapons-grade plutonium.
废弃物的放射性危险会延续数千年，而且部分还可以用来生产武器级放射性元素钚。
It threatens to rebuild Yongbyon and start making weapons-grade plutonium again.
它威胁说要重建宁边核设施并重新开始制造武器级别的钋。
The Yongbyon facilities include a 5mw graphite-moderated reactor and a plant used to reprocess spent nuclear fuel from this reactor, including the extraction from it of weapons-grade plutonium.
宁边的核设施包括5兆瓦的石墨慢化反应堆以及后处理厂在内的一些已用乏燃料(烧过的核燃料后处理)再处理设施，还有为了研发核武器而进行钚提取的设备。
Accounting has since improved, and the country is now thought to have around 145 metric tons of weapons-grade plutonium.
会计方面已经得到改善，国家目前大概有核武原料的145公吨的钚。
According to the Belfer Centre at Harvard University, there is around 1.6m kg of highly-enriched uranium and 0.5m kg of weapons-grade plutonium in the world.
据哈佛大学贝尔弗尔科学与国际事务研究中心的估计，全球大约有160万千克的高浓缩铀，以及50万千克的武器级钚。

宁边的核设施包括5兆瓦的石墨慢化反应堆以及后处理厂在内的一些已用乏燃料(过的核燃料后处理)处理设施，还有为了研发核武器而进行钚提取的设备。
Finally, the reprocessing that occurs in a closed fuel cycle produces plutonium that can be diverted for use in nuclear weapons.
最后，封闭式燃料循环中的再制作过程会产生钸，而钸可能会被用于核子武器。
Technetium-99 is a byproduct of plutonium weapons production and is considered a major U. S. challenge for environmental cleanup.
锝- 99是武器级钚生产的副产物，它被认为是美国环境净化的主要挑战。
Evaporation in the cooling pools used for spent fuel rods led to the detonation of stored weapons-grade plutonium and uranium.
在冷却池的蒸发被用于废燃料棒，导致了储存的武器级钚和铀的爆炸。
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。
