1·This, we now know, is what "well prepared" looks like: total loss of power at the Fukushima Daiichi nuclear reactor, which deprived the reactor core and spent-fuel pools of cooling water.
现在我们都知道，所谓“准备地最充分”就是这样：在福岛大一针核反应堆完全丧失电力供应，使核反应堆中心装置和核废料池冷却水中断供应。
2·When you have an event, the reactor is operating at full power, you blowdown the primary coolant which is hot, you start injecting emergency core cooling water which is cold.
当你进行的时候，反应堆就会用全部的动力，运行，你排放出初冷却剂，那是热的，你开始注入紧急核心冷却水，那是冷的。
3·It accumulates in the cooling water of nuclear reactors and is often vented in small amounts to the environment.
氚会在核反应堆的冷却水中积聚下来，通常会被少量地排放到自然界中。
4·Mercer says a lack of available cooling water could cripple such schemes.
默瑟说，缺少可用的冷却水使得这项方案无从谈起。
5·That means cooling water is not getting to the reactor core, causing a build up of steam inside the containment vessel.
这意味着冷却水并没有进入反应堆核心，从而导致了安全壳内的气压上升。
