This morning at 9:20am local I reduced CP4's LLCV setting to 0% open to cut off LN2 flow into pump reservoir. Kyle connected the HAM 6 backing cart with safety valve to CP4's turbo and will valve in turbo this morning before the pump warms up too much. Currently CP4 is at 58% full. Dave B. readjusted text/email alarms.
Mark D. is removing insulation from GN2 lines - sections that fall within bake inclosure.
Ken is removing electrical conduit, wiring, and supports and will continue this work throughout the week.
Kyle and Gerardo are stripping GV 11,12 of its wiring, controllers, annulus piping, etc.
I'm working with bake enclosure contractor on last minute "gotchas."
Rather than make Kyle work the graveyard shift, I've programmed the set point of CP4 to 20% full with some flow in the transfer line. Ideally we want the pump to dry out during the day when we're in 'work mode' to monitor the turbo-scroll throughput. Reservoir is currently 45% full. Linearally extrapolating yields ~5 hrs duration to fall from 20% to 0%.
The crew made excellent progress today stripping away external components.
We valved out the small ion pump connected to the bottom of CP4.
AIP is still pumping on GV12 due to leaky gate annulus and a pump cart is connected and running (valved out) in case of emergency.
CP4 will fall to 20% full at around 11 pm tonight (if linear) but will likely happen faster.
