The campus cooling water system is still being repaired. We've been
told it may be a few more hours. The campus cooling loop tempers the
building and lab air, so you will have noticed the lab getting quite
warm. Our building loop is cooled by the campus loop; we are now
running equipment using city water in the building loop. The
temperature is better now, but the pressure is much lower than most
tools would like, so some new equipment errors may arise.
The high water temperature appears to have caused our building loop to
spring a few significant leaks in the basement. So, there are concerns
that pressurizing our building loop may result in a flood. We are
scheduling additional Facilities and SNF staff in on Sunday morning to
be on-hand when the building loop is turned back on.
In short, tools with process cooling water problems will remain down for
the evening. We hope to be in a good position to restart tools in the
morning. Our apologies for the inconvenience, especially coming so
close to the shutdown. Please have patience as we all work through this.
Your SNF staff
