So that is the emergency core cooling system for a pressurised water reactor.
所以，那是紧急核心冷却系统，对于一个加压水反应堆而言。
Nuclear plants need power to operate motors, valves and instruments that control the systems that provide cooling water to the radioactive core.
核电厂需要电力去操作电机，阀门，和仪表，去操作控制提供冷却水到反应器内部的系统。
But even after shutdown, there is residual heat that needs to be drawn off by cooling water pumped through the reactor core, and that’s where the trouble came.
但是即便终止之后，依旧有余热存在，需要冷却水泵抽水注入反应堆芯将热量散去，这也是问题所在。
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。
There is a coolant loop no matter what, so you end up to some degree cooling the core because the heated water rises and colder water gets pulled in.
无论哪个都有一个冷却环，所以某种程度上来说你就是冷却核心，因为热水会上升，冷水会被吸入。
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。
Nuclear plants generally need ac power to operate the motors, valves and instruments that control the systems that provide cooling water to the radioactive core.
核电站需要现场电源提供动力操作马达、阀门和各项控制系统的仪表，而且还为反应堆堆芯的冷却水系统提供电力。
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。
The approach to cooling is very simple: push water past the nuclear core and carry the heat somewhere else.
冷却的方法很简单：把水推过核心并把热量带到其他地方。
Inside the core itself, "there is likely no water level," the assessment says, adding that as a result, "it is difficult to determine how much cooling is getting to the fuel."
堆芯内部的“冷却水可能已经蒸发殆尽”，评估报告还说，“无法确定究竟有多少冷却水到达了核燃料所在的位置”。
It is made when speeding neutrons from the reactor's core hit oxygen in the surrounding cooling water.
氮16是来自堆芯的高速中子在周围的冷却水中撞击氧原子的时候产生的。
Salt core Al alloy piston and the new way of shaping cooling channel with water soluble salt core are introduced.
介绍盐芯铝活塞概要和一种新型水溶性盐芯成形内冷却油腔的方法。
Which his related to the core part of air conditioning indispensable "multi-layer corrugated fiber composite materials for air conditioning cooling water curtain" most can be guaranteed.
这其中就关系到空调不可缺少的核心部件——-“多层波纹纤维叠合物水帘”让空调可以大部分降温得到保证。
When a loss-of-coolant accident occurs, it injects emergency cooling water into the core to ensure the safety of a nuclear power plant.
当发生冷却剂丧失事故时，它向堆芯注入应急冷却水，以确保核电站的安全。
During normal operation, it is a stand-by facility. When a loss-of-coolant accident occurs, it injects emergency cooling water into the core to ensure the safety of the nuclear power plant.
正常运行时，它是个备用设备，发生失水事故时，可向堆芯注入应急冷却水，以确保核电站安全。
During normal operation, it is a stand-by facility. When a loss-of-coolant accident occurs, it injects emergency cooling water into the core to ensure the safety of the nuclear power plant.
