pressure containment vessel

基本解释

A release of pressure from the containment vessel of number 2 reactor appears to be planned.
準備計劃釋放2號反應堆的主安全殼內的壓力。
Water in the core began to boil off, raising the temperature and pressure inside the massive steel containment vessel.
堆芯的水開始沸騰，導致鋼結搆的安全殼內部的溫度和壓力開始陞高。
In reactor 1, and later in reactor 3, steam contaminated with some radioactive elements was allowed out of the pressure vessel and into the larger containment vessel that surrounds it.
在一號反應堆以及隨後的三號反應堆中，受到輻射汙染的蒸氣已經從壓力窗口中釋放出來，進入了外層的容器。
