reactor vessel

基本解释

So, the next action needed is to get a set of pumps running to keep coolwater flowing into the reactor vessel and the consequent steam coming out.
因此，下一项措施是需要安装一套水泵，它的运转能够将冷却水送入反应堆容器，生成蒸汽后再返出来。
If the temperature is high enough, the core slumps to the bottom of the reactor vessel and melts through it and onto the floor of the containment unit.
如果温度高到一定程度，堆心就会落到反应堆容器的底部并将其熔穿，从而到达密封装置的底部。
And the list is; reactor vessel integrity which as you probably realise now is reactor vessel embrittlement, pressurised water sump pump performance, we'll look at that.
这个例子是，反应堆槽的完整性就是,现在你们可能意识到的，就是反应堆槽,的脆化，压水式排水泵,的反应，我们观察它。

Integral reactor systems -- including the reactor vessel itself, six steam generators, five primary coolant pumps, 12 isolation valves and more -- were stored outside for up to 18 months, exposed to highly corrosive tropical sea air and weather.

The drywell is a large steel pressure vessel that looks like a giant upside-down pear and holds the reactor and primary pumps, and the wetwell is a large toroidal vessel that looks like a donut.
