Not bad.

Also set a new integrated power record for this run...if you pay attention to that sort of thing.

COMMENT ON B60 CUP Chiller 1 & 2 Power Removal

1 day 9 hours ago
Log Number: 4535097Logbook(s): Body: 

Tentatively adding this to 8/4 maintenance day activities. Approval is pending answers to these questions (copied from e-mail chain):

Typically, the plant is using Chiller 60-CH-3 and 60-CH-4 even on the hottest days so far this year. So, removing power from Chillers 60-CH-1 and 60-CH-2 only means there is no backup chiller available for that period if either Chiller 60-CH-3 and 60-CH-4 were to fail. The larger question is would power be removed from only Chiller 60-CH-1 and 60-CH-2 or would power also be removed from other items such as pumps or control devices?

ES&H clarified to F&O where the last two signs need to go:
1) On the BSY-side of the BSY-Hall C Door
2) On the NL-side of the NL-Hall D Tagger Door.

On Tuesday 8/4 the NL will be in Restricted Access from ~0830 to ~1400. The BSY will be in Controlled Access from ~1000 to ~1400. Let's perform this task then. Thanks.
