The entire primary loop of the nuclear reactor - the pressure vessel, pipes, and pumps that contain the coolant (water) - are housed in the containment structure.

整个最初的核反应循环是这样的——高压管、管道、泵、冷却剂(水)——这些被安装在容器型建筑中。

At unit three the plant managers decided to flood only the pressure vessel hanging in the neck of the containment vessel, not the whole of primary containment.

在3号单元，核电厂的管理人员决定继续注水直到淹没悬挂在安全壳颈部的压力容器处即可，并不需要将整个主安全壳全部注满。

Now this containment obviously must be robust and must be designed such that whatever internal pressure is released from the primary system can be managed by the containment.

现在，很明显这个容器是很稳固的，这样设计所以im无论什么内在的，压力从主系统中呗释放了出来，都能够保持在容器里。
