The water distribution device is an important part of the Passive Containment Cooling System (PCCS), which is a key to carry out the function of the PCCS.
非能动安全壳冷却系统(PCCS)水分配装置是PCCS的重要组成部分，也是系统功能能否实现的关键。
But a bigger blast could have compromised the containment chamber, too-the quake, in a way, to the cooling system's waterless tsunami.
但是，更大的爆炸可能毁掉控制室，在某种程度上，地震和海啸让冷却系统失灵了。
The nuclear fuel rods in reactors one, two and three melted down due to a failure of the cooling systems, causing damage to their containment structures.
一号、二号和三号反应堆中的核燃料棒因冷却系统失灵而熔毁，导致其围护结构遭受破坏。
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。
Hydrogen collected in the secondary containment buildings, where it exploded, blowing the tops off units 1 and 3, and damaging the cooling system of unit 2.
氢气在第二层安全壳内聚集，最终爆炸，将1号和3号的顶盖炸飞，损毁了2号的冷却系统。
