钚
1、锕系元素中的放射性金属元素,原子序数94。是制造原子弹的主要材料之一 ——元素符号Pu。
最棒的是这一过程能够自我供能——钚被裂变破坏时释放能量,这一能量可以供给燃烧炉。
The best part is that the process can power itself—plutonium releases energy as it destroyed by fission, and that energy can power the burner.
钚会不会存在于饮用水里呢?
What about plutonium in the drinking water?
还需要禁止测验和制造铀和钚用于核弹。
It needs a ban on tests and on making uranium and plutonium for bombs.
他被要求不再生产钚和铀。
He was to stop making plutonium as well as suspected work on uranium.
不是裂变,靠那个铀和钚,变成碎片,而是聚变。
Not fission, whereby uranium and plutonium breaks up in pieces, but fusion.
据推测放射性钚元素来自受损核反应堆的核燃料棒.
The Plutonium is thought to have come from some of the plant's fuel rods found in each of the troubled reactors.
混合氧化物燃料棒含钚,这些燃料棒已经部分暴露。
Mixed oxide fuel rods are partly made of plutonium. These fuel rods are partly exposed.
因此其它五方说服自己现在搞清楚钚的数量就可以了。
So the other five persuaded themselves that the plutonium count would do for now.
这就终将会允许印度从美国已经用尽的燃料中提取出钚。
This will eventually allow India to extract plutonium from spent reactor fuel of American origin.
这些试验中的一些试验包括了粉碎或射击钚元素的小碎片。
Some of these tests involve smashing or shooting at small shards of plutonium.
这也是一个不大的威胁:钚是一种重元素并且不易被水溶解。
It, too, is a relatively minor threat: Plutonium is a heavy element that does not dissolve easily in water.
但在福岛核电站附近土壤中发现了一种更加危险的物质——钚。
But a more dangerous material, plutonium, has also been found in soil near the power plant.
炼金术,或嬗变,已经在元素周期表中增加了新元素,包括钚。
Alchemy, or transmutation, has placed new elements on the periodic table, including plutonium.
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。
Uranium and plutonium are most likely to find their way into weapons via the enrichment and reprocessing of fuel for nuclear power plants.
他说:“我帮助做的一些实验与钚环核心的尺寸和结构直接联系。”
"Some of the measurements I helped do were directly related to the size and configurations to the nuclear cores of the plutonium bombs," he said.
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。
Accounting has since improved, and the country is now thought to have around 145 metric tons of weapons-grade plutonium.
日本通过混合钚和铀以制造混合氧化燃料的设施中也已存在类似的问题。
Japan has had similar discrepancies at a plant that blends plutonium with uranium to make mixed-oxide fuel.
钚和其它的放射性元素的混合物可以转变成适宜“快”反应堆使用的燃料。
This mixture of plutonium and other radioactive elements couldthen be turned into fuel suitable for use in “fast” reactors.
现在还不清楚3号反应堆发生了什么情况,3号反应堆的燃料是混合的铀和钚。
It remains unclear what is happening with the Number-3 reactor, which is fueled by a mix of uranium and plutonium.
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。
In a major and welcomed development, Russia announced that it will close its last weapons-grade plutonium production reactor.
但更强烈的冲击可能会把潜艇和船员一起送到海底,并且把钚混进周围的海水里。
But a stronger impact could have sent both subs and their crews to the bottom and possibly dispersed plutonium into surrounding waters.
核能,是铀或,钚的裂变,在70年代很受欢迎,但最近受欢迎程度,有所下降。
Nuclear energy, which is the fission of uranium or plutonium, was very popular in the '70s, but it has become a little bit less popular lately.
这些建议都以国王愿意接受更为严格的钚加工控制为基础——属于美国的特别关切。
These proposals were all predicated on the shah's willingness to accept more rigorous controls over plutonium processing -- something that was of particular concern to the United States.
新型的反应堆被设计出来,包括由钚提供能量,液态钠参与冷却的快中子增殖反应堆。
New types of reactors were designed, including the Fast Breeder reactor powered by plutonium and cooled by liquid sodium.
