from The Century Dictionary and Cyclopedia
- n. A tube of thick glass originally closed at one end and, after the introduction of liquid reagents, closed also, by fusion, at the other. On cautiously heating such a tube interaction of its contents may be brought about at a much higher temperature than would be possible in an open vessel and therefore under ordinary atmospheric pressure.
- n. The brass, or German silver, or highly elastic steel tube used in the Bourdon pressure-gage.
Sorry, no etymologies found.
Hydro never doubted that a pressure-tube crack, or an incident far more serious, could be handled safely.
Unlike several other incidents that have happened over the past few months at our nuclear stations, the pressure-tube crack was a significant and unique problem.
For the next few minutes, I'd like to talk about the recent pressure-tube crack at Pickering.
However, there is increasing concern in the aftermath of the Three Mile Island accident and the current pressure-tube problems at Pickering - I expect Mr. Nastich feels jinxed every time he hears the words "pressure tube" - as to whether in the long term nuclear power is indeed cheaper, whether it is environmentally better in terms of disposal of highly radioactive nuclear waste, and above all, whether it is safe.
He thrust the message into his pocket, and his step quickened as he heard the whistle of the pressure-tube trains up ahead.
