An annual electrical and mechanical inspection was performed on the SMP today by Adam Newsome, Dan McDonald, and Jason Zhang as per Work Permit I2021-07-07-3. The following items were checked:

  • Check condition of wiring for physical/radiation/UV damage
    • OK, no signs of significant damage
  • Check for cable tray debris or damage
    • There were multiple shards of plastic in the cable tray - they were removed and disposed of
  • Check inside control panel: components and wiring, labeling
    • Labeling intact, components in good condition
    • One COM wire for the relay array was loose - it was tightened
  • Verify camera views
    • This was not inspected but has recently been checked, and is checked prior to remote operation
  • Check connectors for damage
    • All connectors OK
  • Check pendant for damage and verify labeling intact
    • Pendant OK
  • Lid open/close test
    • Lid was opened and close multiple times - smooth operation, no concern
    • Lid close logic was checked - OK
  • Vessel rotation and limit switch check
    • Both CW and CCW limits were checked, functioning
    • No concern on rotation - chain drive, rotary limit switch, and cable reel all functioning normally
  • Lubricate chains
    • Done
  • Inspect tensioners
    • Done - OK
  • Tighten fasteners
    • Done - OK
    • Note: some concern over socket head screws in slotted parts - they should have washers. Not a critical issue but worth checking into.
  • Visual inspection
    • All OK

Overall the inspection was successful.

 Yesterday a bottle of Cava (sparkling wine) was place, opened, and poured in the NHC, to commemorate its new operational status.

The NHC is now a functional hot cell and is ready for many years of target exchanges to come.

Both electrical check and leak check (HS and Window lines)results are good.   See attachments

Correction: It should be UCx#32 P2N instead of UCx33# in check list attached . UCx#33 is on TM2 in ITW

Entry  Tuesday, May 25, 2021, 15:59, Matthew Gareau, North Hot-Cell, Development, , , Removed boot from left hot manipulator 7x

 Myself and Isaac removed the boot from the left hot manipulator.

- opened the hatch in the TH to get access to the top of the boot

- released the latch on the boot and loosened the boot from above

- closed TH hatch

- with the right manipulator we were able to detach the rest of boot

This test proved that we can remove a boot from the manipulator without having to enter into the hotcell.

Due to the physical restraints that the boot causes for the operator, we have decided to not reattach the boot with its current design.

A new design will be investigated to allow the boot to be fixed without twisting, which is the source of the problems.

Resistance measurements on each electrical feedthroughs (A,B,C,D,E,I,P,Q,R,U,60kV,ground) taken with no target or no short attached to the module. Results as expected:

P-Q = 6.439 mOhm

R-U = 6.019 mOhm

All other combinations = Open Loop
