中文简介:
穆罕默德巴拉迪说:“我们站在十字路口:我们要么利用核能来实现全球安全,要么看着核技术导致全球灾难。这一鲜明的分析来自于巴拉迪对“有无世界”的广阔视野:16亿人无法获得现代能源服务,能源供应和相应的生活水平的差异造成了机会和希望的差异。毫不奇怪,一些发展中国家成员被这种情况激怒了。巴拉迪说:“当我们想了解恐怖主义和极端主义的兴起时,我们需要回到根源上来。”当全球紧张局势升级时,西方国家和亚洲新兴经济大国对能源的需求增长如此之快,以至于不清楚在未来几十年,受市场动荡影响的化石燃料供应是否足以满足需求。巴拉迪说,考虑到这种严峻的形势,建造新核电站的理由正在取得进展。它们排放的温室气体很少,为实现能源独立提供了相对便宜的途径。但巴拉迪警告说,“单靠核能并不是万能药。”创新必须解决废物产生、建设成本和安全等突出问题。不过,更大的问题涉及政治领导。将核燃料转化为武器的技术障碍已基本消失,因此,当一个非核国家提议建立一个新的核浓缩或后处理设施时,它就构成了一个地区或世界性的威胁。Elbaradei说:“这不是我们想要生活的那种安全模式。”核俱乐部的最初成员必须认真对待裁军问题,并签署新的区域解决方案,使所有国家都能公平、安全地获得核燃料。
课程简介: We stand at a crossroads, states Mohamed ElBaradei: We can either employ nuclear energy to achieve global security, or watch nuclear technology lead to a global cataclysm. This stark analysis emerges from ElBaradei’s broad vision of a world of haves and have-nots: 1.6 billion people lack access to modern energy services, and the “disparity in energy supply and corresponding standard of living creates a disparity of opportunity, and of hope.” Not surprisingly, some members of the developing world are enraged by this state of affairs. “When we want to understand the rise of terrorism and extremism, we need to go back to the root causes,” says ElBaradei. And while global tensions rise, the demand for energy in Western nations and in emerging Asian economic giants is escalating so fast that it’s unclear if fossil fuel supplies, subject to market turbulence, will suffice in the coming decades. Given this grim scenario, the case for constructing new nuclear energy plants is gaining ground, says ElBaradei. They emit little greenhouse gas and offer a relatively inexpensive route to energy independence. But “nuclear energy alone is not the panacea,” cautions ElBaradei. Innovation must tackle outstanding problems, such as waste generation, construction costs and safety. The larger issues involve political leadership, though. The technological obstacles to converting nuclear fuel to weapons have largely disappeared, so when a non-nuclear nation proposes building a new nuclear enrichment or reprocessing facility, it poses a regional or worldwide threat. This is “not the kind of security model we’d like to live under,” says ElBaradei. The original members of the nuclear club must get serious about disarmament, and subscribe to new, regional solutions that give all countries equitable and safe access to nuclear fuels.
