and we will call upon countries to begin negotiations in january on a treaty to end the production of fissile material for weapons.
我们将呼吁各国从明年一月开始谈判一项协议,以终止可用于武器的裂变材料的生产。
even the test ban and a new treaty to cut off production of fissile material—both obvious first steps to a nuclear-free future—will be dogged with difficulty.
即使是禁止核试验和起草一份降低核裂变材料生产的新条约-----很显然,二者都是迈向无核未来的第一步----困难也将会如影随形。
argentina, italy and the united arab emirates said they were working to install radiation detectors to check cargo for fissile material.
阿根廷、意大利与阿联酋表示,他们正在安装辐射探测装置,以检查夹带在货物中的裂变材料。
they compress the fissile core, or pit, of the warhead until it reaches critical mass.
该技术可以将裂变核心或者弹芯压缩至临界质量。
as a first step towards outlawing nuclear weapons, america should seek a new treaty that verifiably ended the production of fissile materials 「intended for use in state nuclear weapons」.
作为废除核武器的第一步,美国应当寻求一项新的协议确证地结束「用于一国核武器」的裂变物质生产。
thus, we need to start getting rid of this material along with fissile material created for weapons use.
因此,我们在清除用于制造武器的裂变材料的同时也需要开始清除这类材料。
it did not win backing for new anti-proliferation obligations, such as a legally binding test ban or for an end to the further production of fissile uranium or plutonium for bombs.
该交易不会支持关于反核扩散的新义务(例如一个禁止核试验的有约束力的协议),也不会鼓励结束进一步制造武器用途的裂变铀或钚。
a whole clutch of these—algeria, egypt, jordan, libya, morocco, saudi arabia, tunisia, turkey and yemen—are in the fissile middle east.
一连串的这些国家——阿尔及利亚、约旦、利比亚、摩洛哥、沙特阿拉伯、突尼斯、土耳其以及也门——都位于裂变性的中东地区。
it's true that the nuclear enrichment and reprocessing facilities used to produce fuel for peaceful reactors can just as easily be used to make fissile material for bombs.
用于和平建设目的的核反应堆所需要的铀浓缩与后处理设施同样可容易地用于制造核武器所需的裂变材料。
and the chemical-explosive detonator can also be tested using 「simulants」 that are not fissile but mimic the behaviour of the plutonium pit in other ways.
此外,化学爆炸物也同样能通过「模拟物」来试验,该模拟物不是裂变物质但它能通过其它方式模拟出钚核的运动方式。
we will pursue ratification of the comprehensive test ban treaty. and we willseek a new treaty that verifiably ends the production of fissile materialsintended for use in nuclear weapons.
我们会努力促进禁止核武器试验条约的施行,我们也在试图推行一个阻止生产可用于核武器的核裂变材料的条约。
this chart gives you a summary of some of the critical thermal-neutron cross sections of important fissile and fertile nuclides.
这个图表给你们一个重要的,可裂变和可转换核素的,一些临界热能中子横截面的总结。
