There is a coolant loop no matter what, so you end up to some degree cooling the core because the heated water rises and colder water gets pulled in.

无论哪个都有一个冷却环，所以某种程度上来说你就是冷却核心，因为热水会上升，冷水会被吸入。

There are mainly two excitation mechanisms in the vibration of the thermo-well at the main pipe of reactor coolant loop under cross flow: turbulence and vortex shedding.

反应堆冷却剂回路温度计套管在流体流动冲刷下的振动主要有两种激励机理：湍流和旋涡脱落。

Another module continued to pump coolant through a separate loop, but astronauts had to power down non-essential equipment to prevent overheating.

另一个模块继续通过一个单独的循环泵入冷却剂，但宇航员不得不关掉不必要的设备以防止过热。
