放射性核废料是核能的致命缺陷?
图片报道:俄罗斯捷科河遭受放射性核废料污染。
根据合同,该公司要在世界范围内维修大量现存的反应堆。同时,该公司也涉及处理放射性核废料以及除役旧式核设备。
The firm has contracts to maintain existing reactor fleets around the world, and is involved in processing radioactive waste and decommissioning old nuclear facilities.
其他大量的放射性材料,从废弃的X光机到核废料,可能被用于制造脏弹。
And that larger amounts of other radioactive material, from discarded X-ray machines to spent fuel, might be used to make a dirty bomb.
放射性废料管理委员会本身只是一连串处理核废料问题的委员会之一;到底在哪里建立这么一个储藏库呢?这个细微的问题难倒了之前的提出所有尝试的人。
CORWM itself is merely the latest in a string of committees set up to deal with the problem; all previous attempts stumbled on the delicate question of where such a bunker could be built.
如果在核废料周围建造一个类似三维深沟的水笼,地下水便被赋予一条替代路径,不会渗入放射性物质。
If a cage of water -- sort of like a three-dimensional moat -- isbuilt around the sealed-off nuclear waste, the groundwater is given analternate path.
在其中有一些容器发生渗漏事故使得放射性废料流入环境以前的很长时间里,人们相信核废料的问题已经解决。
For a long time it was believed that the nuclear waste problem had been solved, until some of these tanks leaked, allowing the radioactive waste to seep into the environment.
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。
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.
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。
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.
