Notes From Ops Shift Check Sheet

1) FOM Scan

USGS webpage needed a reload (it had froze).

2) Dust Monitor Check Notifications for LVEA5 & LAB2

Ran the "check_dust_monitors_are_working" script and have had the usual:

  • *H1:PEM-CS_DUST_LVEA5      WARNING: dust counts did not change, please investigate
  • H1:PEM-CS_DUST_LAB2                      Error: data set contains 'not-a-number' (NaN) entries

2)  Access System "Flashing Doors"

  • EY has (2) flashing doors, but I'm pretty sure this has been ongoing for years.
  • VPW has 3 door issues:  Exterior Roll-up, LDAS entry, Dirty shop entry & Wood shop has Roll-up door issue.

3) LHO Control Room Screenshots & FOMs

  • H1 Glitches (nuc27) not posting (this has been the case for a while)
