回想我们也可以有快速裂变。
如果我们在这开始，生产的快速中子,通过裂变，通过热能裂变,你加入生产的快速,中子的全部数量。
So if we start up here, fast neutrons produced by fission, by thermal fission and then you add the total number of fast neutrons produced.
这种再处理工艺，或甚至快速中子反应堆不使用水来缓和裂变，及比他们消耗量创造更多的燃料，仍是一个遥远的前景。
Such reprocessing-or even fast-neutron reactors that don't use water to moderate fission and can potentially create more fuel than they consume-remain a distant prospect.
很多美国人都担心，关注着美国快速老化的核电站，很多都已经超过了反应堆当初的设计使用寿命，但仍在通过铀裂变发电。
Most American worries focused on the integrity of our nation's rapidly aging nuclear power plants, many of which are still churning through uranium long past the reactors' original expected lifetimes.
现今的磷灰石裂变径迹年龄格局基本上受控于白垩纪的快速抬升冷却事件，但最后为晚期活动断裂所定格。
The present AFT age pattern is, therefore, basically controlled by the Cretaceous rapid cooling event but finally shaped through active faults.
