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。

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。

Water in the core began to boil off, raising the temperature and pressure inside the massive steel containment vessel.

堆芯的水开始沸腾，导致钢结构的安全壳内部的温度和压力开始升高。

That is a very different situation than at Fukushima Daiichi, where the fuel in three reactors is thought to have burned holes in their immediately surrounding pressure vessels, and in one case to have fallen all the way through to the bottom of the outer containment vessel.
