Because the reactor had been shut down a long time ago, the decay heat had decreased to a significantly lower level, so the pressure in the plant stabilized, and venting was no longer required.

因为反应器已经关闭了很长时间，残余热量下降到了一个显著的低水平，因此工厂内部的压力已经稳定，不再需要继续排气。

Caution: Do not direct water streams toward venting oxygen. The water will freeze and plug the pressure-relief vent, which may result in container failure.

警告：禁止直接让水流向正排出的氧。水会结冰并堵塞减压装置的出口，这会造成容器故障。

In particular, it will have to look into what happened on the night after the tsunami, when there was a delay in "venting" pressure building up in one reactor.

尤其需要查证海啸发生的当晚，即延迟为一个反应堆装备释放压力的时候，到底发生了什么。

The highest number was 679 millisieverts, for a worker who helped to prepare venting as rising pressure threatened an explosion.
