That means cooling water is not getting to the reactor core, causing a build up of steam inside the containment vessel.

这意味着冷却水并没有进入反应堆核心，从而导致了安全壳内的气压上升。

We had to actually raise the temperature of the emergency core cooling system because the NRC thought our vessel was somewhat embrittled.

我们必须提高紧急核心冷却系统的温度，因为核管理委员会认为，我们的管道不知怎么变脆了。

The glaze is applied to a fired stoneware vessel, which is then fired again in a repeated cycle of six stages of heating and cooling where precise temperatures matter a great deal: either over- or under-firing will spoil the effect.
