托福听力原文绝对占有很重要的位置。今天给大家带来一篇关于核电站断电事故的托福听力原文，以便在托福听力中的素材积累。
“The type of accident that is occurring in Japan is known as the station blackout: loss of off-site AC power—power lines are down—and then a subsequent failure of emergency power on-site, the diesel generators. The station blackout has been one of the great concerns for decades.”
Physicist Ken Bergeron, speaking on March 12 during a press briefing. He worked on nuclear reactor accident analysis at Sandia National Laboratories.
“The probability is hard to calculate primarily because of the possibility of what are called common-cause accidents, where the loss of off-site power and of on-site power are caused by the same thing. In this case the earthquake and tsunami. We’re hoping that all of the barriers to release of radioactivity will not fail. So far the first barrier, which is the fuel cladding, has apparently failed, because they are detecting cesium. We now have to hope that the subsequent layers, including primarily the containment building, will succeed in preventing release of major amounts of radioactivity.”

在一次新闻发布会上，物理学家肯·贝热龙解释了发生在日本福岛上的事故的类型。史蒂夫·米尔斯基报道。
“发生在日本的事故属于所谓的电站断电类型：站外交流电源掉线-因为电源线断掉了-然后站内紧急电源柴油发动机接着失灵。电站断电是几十年来比较大的担忧之一。”物理学家肯·贝热龙在3月12日的一次新闻发布会上说到。他在桑迪亚国家实验室从事核反应堆事故分析。
“这个几率很难去计算的原因主要是因为发生所谓共发生事故的可能性，也就是说造成站外及站内电源掉线的是同一个原因。在当前情况下就是地震和海啸。我们希望所有防止辐射泄漏的屏障不要失败。目前第一层屏障，也就是燃料包层，明显已经失败了因为他们已经检测到了铯。
我们现在只能希望接下来的防护层，主要包括屏蔽大楼，能够成功阻止主要的辐射泄漏。”
