[Lerftest] Discussion points for today

[Kevin Jordan]

HI Neil,
I will test & sign off on this instrumentation, PSS group will test flow switches for operational functionality in the MPS.
The water flow switches (MPS) are all set for 0.1 PGM, here are expected temperature rises:

POWER DISSAPATED IN ISOTOPE RIG kj 10/9/2019
Minimum Flow Rate
Piece   Power  (W)      Factor  GPM     Delta C Resulting T
Window  5       265     0.1     0.1887  35.1887
Tungsten        103     265     0.1     3.8868  38.8868
hBN/Gallium     892     265     0.1     33.6604 68.6604
Total   1000
Desired Flow Rate
Piece   Power  (W)      Factor  GPM     Delta C Resulting T
Window  5       265     0.1     0.1887  35.1887
Tungsten        103     265     0.1     3.8868  38.8868
hBN/Gallium     892     265     1       3.3660  38.3660
Total   1000

All of the flow rates are monitored & strip tooled in EPICS, higher flow is fine but preference is to be given to the “Base Cooling” as referenced on the PID. I will cross calibrate the turbine flows with a separate Datel unit, to confirm flows are correct in EPICS.

Thanks
Kevin

Hi Kevin, Todays meeting was helpful, Thanks.
Couple of ???. Once we complete the isotope cooling water & N2 lines who will check them out from a functional stance and sign off that they are ready so we can install the SEG blocks & steel plate.
Thanks
