containment vessel

The reactor vessel is surrounded by a thick steel-and-concrete primary containment vessel, equipped with a water reservoir designed to suppress overheating of the vessel.

反应堆由一个钢与混凝土构成的厚实外壳（第一层安全壳）保护着，另外还配有一个蓄水库，防止反应堆过热。

The outer housing of the containment vessel at the No4 reactor erupted in flames early Wednesday, said Hajimi Motujuku, a spokesman for the plant's operator, Tokyo Electric Power Co.

福岛核电站所属的东京电力公司的一名发言人称，周三清晨，第四反应堆安全壳外部再次发生火情。

If engineers are unable to cool a damaged fuel core, enriched uranium can melt into a pool of radioactive lava. The meltdown can burn its way out of the containment vessel or send radioactive steam out through cracks in the system.

如果工程师们无法成功冷却受损燃料核心，浓缩铀会像一滩具有放射性的熔岩，烧穿安全壳，或者让具有放射性的水蒸气从系统裂缝流入外界。

In Japan and the United States, a thick concrete and steel containment vessel surrounds the reactor vessel.

在11区和美帝，反应容器一般被一层厚厚的钢筋混凝土包裹。

To compare the results, numerical simulation of a monobloc thick-walled explosion containment vessel was also investigated.

作为比较，对相同尺寸的单层圆柱爆炸容器也作了相应的模拟。
