The emergency close mechanism for the Storage Vault door was tested by Adam Newsome and Travis Cave. The door was opened to its fully open limit, then closed with the emergency system.

The test was successful.

At SHC: HS line no leak . electrical check result is fine. At TCS: helium pressurized HS line to 70psi, 3 minutes. LD  leak rate 0.0xE-9atm.cc/sec , no response.

Remotely remove TM4 (ta# 62) from SHC to TCS.  The moving is smooth.

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.

TM2 has been connected it ITW.  All turbo pumps are started.

Leak checked TM2 service cap at TCS. helium pressure checked containment box window and HS cooling lines.  No leak on service cap and waterlines.

TM2 UCX33# electrical check and leak check results. See attachment.

Chad installed containment box back to TM2 yesterday. We leak checked VCR joints on window line.    No leak.

Annual ITE water signal interlock check is done.  HS, TAR, TUBE, MSP, EE, COIL 1, containment box window, HVC1, HVC2, 2A window, 2A  shielding plug, 2A dump, 2A collimator, and 2A tank water signal interlock are checked.   Everything is working properly.  

2021-06-22. Annual ITW water signal interlock check is done,  HS, TAR, MSP,  EE, COIL1 , containment box window, HVC1 , HVC2, 2A window, 2A shielding plug, 2A dump, 2A collimator, and 2A tank water signal interlock are checked. Everything works fine.

 TM#2 has been moved from the SHC to the NHC.

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

Remotely removed Tm2 from silo to SHC. The moving is smooth.

Replaced  ITE TP4 due to failure start. The new pump works fine.

Remotely remove tm4 from silo to shc. The moving is smooth.

Tank refilled from 12 in to 25 in using the new valve.

A contractor on site today for chiller maintenance. CP2 and CP3 circuit is leaking and shall not be used. CP1 can still be used. The contractor will contact Plant Group with a quote for repair and upgrades.

 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.

Repack of 4 spent targets in TH and SHC.  SiC#37 to new pail249#. SiC#36 to new pail 250#. Nb#8 to new pail 247#, SiC#33 to new pail 248#.  They are all in mini storage. Also, UCx 31 are transferred to mini storage.  There are 5 spent targets in mini storage now.  

2021-05-20: 5 spent targets have been loaded into F308's. We transferred two more spent targets into mini storage this morning for next week loading.

 Anders and I prepared ITE high voltage test in April 30 ( Friday morning), The MAA is locked for this.
