The powerful system has the capacity to propel thousands of gallons of water a minute throughout a reactor pressure vessel and storage pool.

这种强力的系统有能力在一分钟内驱动上千加仑的水流经反应堆的高压容器和储存池。

The reactor core which includes these rods, and the water it sits in, are contained within a thick steel pressure vessel.

这些燃料棒就是反应堆的核心，它位于水中，并包裹在厚厚的钢制压力容器中。

The entire "hardware" of the nuclear reactor - the pressure vessel and all pipes, pumps, coolant (water) reserves, are then encased in the third containment.

核子反应堆全部的“硬件”——压力管，所有的管道，泵、冷冻剂(水)储备，通通放入第三个容器。

In addition, the modular design could make it more difficult to inspect and maintain key components, many of which would be located within the pressure vessel at the heart of the reactor, he said.

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.
