Sprinkling in the rain
Is anyone responsible for checking the weather forecast and monitoring the sprinkler system at ORNL? I happen to notice the sprinklers in front of the cafeteria right as I came through the round-about this morning. Was I surprised to see the sprinklers on as it was definitely raining. Surely in this day and age of conserving our resources and saving money on frivolous things and being at a lab that prizes itself on great research, something could be done to design a sprinkler system that doesn't come on when it is raining.

F&O's George Baber responds:
All of the ORNL sprinkler systems have a rain delay mode which requires each one be unlocked and manually switched into that mode and then manually re-set to operations mode after the rainfall event. There are about 12 separate controllers plant wide from HFIR to the Visitor Center, and we try to switch them into rain delay when we know rain is in the forecast. Sometimes we forget or miss a controller, or the weather is simply too unpredictable.
