Radioactive waste is simply spent fuel 放射性废物就是用后的燃料。
Cooling the spent fuel is critical, for if it becomes exposed, a zirconium fire can break out and spew massive amounts of radiation. 冷却用过的核燃料至关重要,因为一旦它暴露在外,就可能引发锆火灾,从而排放出大量放射物质。
The quake also briefly disrupted efforts to resolve the crisis at the Fukushima Daiichi plant, where workers have been battling to prevent dangerous overheating of nuclear reactors and spent fuel since the tsunami knocked out back-up cooling systems. 此次余震还短暂中断了福岛第一核电站的抢险努力,自海啸冲毁备用冷却系统以来,工作人员一直在竭尽全力阻止核反应堆和废燃料棒出现危险的过热。
Reprocessing of spent fuel 烧过的核燃料后处理
Clearly Fukushima-Daiichi showed us that we have to consider the possibility of multiple units at a single site, perhaps multiple spent fuel pools being affected at the same time. 但是福岛第一核电厂事故很明确地显示,我们必须考虑到在单一地点多个反应炉可能同时发生问题,可能多个冷却池水同时受到影响。
The operation was intended to help cool the reactors and also to replenish water in a storage pond with spent fuel rods. 这次行动的目的是给反应堆降温,同时为装有用过的核燃料棒的水池补充冷却水。
This is the pool where spent fuel rods are kept cool, just like the one that malfunctioned in the Japanese plant. 这是乏燃料冷却水池,跟日本核电站发生故障的水池一样。
We also need to cool the reactor and the spent fuel in the spent fuel pool but that basically means you wanna maintain the coolant inventory which means water in the primary system. 我们也需要冷却反应堆,还有乏燃料,在乏燃料池里,但是那基本上意味着,你们想要维持冷却剂存货,也就是在主系统中的水。
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。
And that larger amounts of other radioactive material, from discarded X-ray machines to spent fuel, might be used to make a dirty bomb. 还有更多的其他一些放射性材料,如废弃的X光机以及燃料残渣,都可以用来制造脏弹。
As many of you know the current strategy in the United States is a once through fuel cycle in which the fuel goes right from the reactor to storage and then as spent fuel is to be disposed*. 正如你们所知,现在的策略是,在美国,一旦有了一次燃料循环,过程中,燃料从反应堆的右边,在储存的地方,然后成为乏燃料被处理。
The kinds of problems posed by the back end of the fuel cycle depend in part upon whether spent fuel is recycled. 在这个问题上别说废话。燃料循环的最后部分提出的问题种类,部分地取决于废料是否再循环。

Whether or not spent fuel is recycled, there ultimately is the problem of how to dispose permanently of high level radioactive wastes. 无论这些核废料是否再次循环,都有一个怎样永久性地处置高放射性废物的问题。
In the field of nuclear waste management, some countries have made technological breakthroughs in dealing with spent fuel. 在核废料管理领域,一些国家在乏燃料的处理方面取得了技术突破。
Under the pact, Russia will supply the fuel for Bushehr and then take back the spent fuel rods. 根据条约,俄罗斯为布什尔提供核燃料,同时回收废核燃料棒。
Experts say it is expensive and difficult to process such spent fuel. 专家称,其废料处理技术复杂且成本昂贵。
The US is stopping work on the Yucca mountain project-its only potential repository for spent fuel. 而美国正在停建尤卡山项目&它唯一可能的废燃料储存库工程。
Those drawing fuel would have to agree to strict verification and to return spent fuel for oversight. 获取燃料的那些国家将必须同意接受严格的核查,并返还乏燃料以便监督。

Table S-3 contained a set of numerical values intended to quantify the radiological effluents associated with reprocessing, storage, and disposal of spent fuel and other wastes. 表S一3含有一套数值,这些数值可以用来量化放射性污物,这些污物都与核废料和其他废物的加工、贮存和处理有关。
These include terrorism, what do we do with spent fuel? The pump-sump question. 这些包括了恐怖主义,如何处理用过的,燃料,还有泵油池问题。
Separately, Japan's national broadcaster NHK reported Sunday that firefighters will soon resume operations to spray water onto the No.3 reactor in a bid to cool down its overheating spent fuel pool. 另外,日本国家电视台NHK周日报道说,消防员很快将会继续对三号反应堆喷水,以冷却过热的乏燃料池。
He said Thick clouds of steam, thought to be from water evaporating in the spent fuel pool, is hampering their work. 厂房里浓浓的水雾妨碍他们工作的进行。人们认为,这些水汽来自废燃料池。
The unmanned aircraft took photographs and could roughly gauge temperatures inside the damaged reactor and spent fuel buildings. 这架无人驾驶飞机进行拍照,可以粗略测量受损的反应堆和耗尽的燃料建筑内的温度。
Yet the West should persist in reminding it of the gains it would enjoy if it were to eschew deceit and show flexibility, say by letting spent fuel from reactors be taken to neutral third countries. 但西方应该不懈地提醒他们,如果放弃欺骗并愿意妥协(例如把反应堆中用过的核燃料运往中立的第三国),他们会享有什么样的好处。
2011-01-04 Chinese scientists have made a breakthrough in spent fuel reprocessing technology that could potentially solve China's uranium supply problem, Chinese television reported. 2011年01月04日中国媒体近日报道,中国科学家在“动力堆乏燃料后处理”技术方面取得突破,这将可能解决中国铀资源供应上的困难。
In general, when doing analyses of criticality safety of spent fuel transport or storage, one assumption is that the compositions of the spent fuel are same as the fresh fuel. 然后再利用上一步计算得到的乏燃料成分,对特定结构的水池进行临界安全分析。
The concern focused in particular on overheating of the spent fuel rods. 各方的关注焦点是废燃料棒的过热。
