High active water system is refilled. Air are drained out of  system before pump to be started. Following sequence are used to bring the whole system back to operation:

1. close ITE , open ITW. Switch on the pump. Only 2A beam line related 5 water circuits are in loop in ITW.  Switch off pump when system pressure is stable above 100 psi.

2. Close ITW, open ITE. Switch on the pump. Only 2A beam line related 5 water circuits are in loop in ITE. Switch off pump when system pressure is stable above 100psi.

3. Open ITW, Open ITE. Switch on pump. both ITW and ITE beam line related water circuits are in loop.  Switch  off pump when system pressure is stable above 100psi.

4. Close ITE open ITW.  Bring ITW  target module water circuits back to loop by connecting bypass fittings on to circuits. Only bring one circuit back to system at first. Switch on pump. Wait for system pressure stabilized. Then Close ITW. bring next circuit back  to system.  Open ITW .  wait for pressure stabilized.  repeat the process until all water circuit and connected with bypass fittings in ITW.

5. Check possible leak on valves, fittings, and flow sensors in ITW pit.

6. Go to electrical room, check all ITW water signal status.

7. Close ITW, Open ITE. Repeat same procedure as step 4 on ITE target module water circuits.

8. Check possible leak on valves, fittings and flow sensors in ITE pit.

9. Go to electrical room, check all ITE water signal status.

10. Open ITW.  At this stage, full ITE station and half of ITW station water circuits are in operation.  Check possible leak on pumps, valves, fittings, gauges on water station at TH west end.

11. Keep system in operation. Watch on - tank level , system pressure, and conductivity on resin circuit and whole system.

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

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.

 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.

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.

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

 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.

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.

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.

See the attached for the way ITE has been re-wired for the Ta62 run. Note also that the copper block in the schematic on TBHT negative may not actually be connected. Wiring verification on Aug. 4.

UC#33 has been packed and moved from the north hot cell to the spent target vault. See attached PDF for 
deatails

The West Entrance Module has been moved to the South Hot Cell for repair.

A cable track was installed between the mini-storage vault and the silos, for the purpose of implementing a retractable cable chain (e-chain). This will allow for cables to be managed during door opening/closing, so that remote control operation of the door will be possible in the future. See Work Permit I2021-08-11-2 (Aug 11)

Holes were drilled into the motor mounting plate (IRH2089) to allow for mounting a limit switch on the plate. See Work Permit I2021-08-17-7 (Aug 17)

Preliminary testing was completed in which the e-chain was fixed to the door with a C-clamp. Local and remote functionality were checked, and limit switch functionality was verified. Everything is working as expected. A final test will be conducted once the e-chain is fixed to the door and cabling routed through it. See Work Permit I2021-08-19-1 (Aug 19)

The e-chain has not yet been fixed to the vault door - holes will be drilled in-situ after preliminary testing is complete to confirm positioning.

 Edit [2021-09-23]: the installation is complete and has been tested.

The West Entrance Module has been moved from the South Hot Cell to the West Target Station.

 The spent Ta#62 target along with 2A2M19 were placed in pail #256 and placed in spot 7A of the spent target vault. See attached PDF for vault details.

 The spent UC#34 target was moved from the north hot cell to the spent target vault. See attached PDF for details.

Remote capability was added for the mini-storage door control. The control signals originate from the Opto 22 Module box that is used for the SMP remote control (this is located just above the storage vault).
The controls signal assignment document has been updated and can be found in C:\PDM Vault\PDM_Vault\_models\isac\isac1\wpn-3919 - safe module parking\Electrical

In order to operate remotely:
- Plug the mini-storage control box power cable into a wall outlet (adjacent main storage vault, under stairs)
- Plug the motor output cable into the mini-storage door motor
- Unplug the local pendant from the box
- Plug the cable that comes from the remote module box into the connector that the pendant was plugged into (M12, 5 pole Murr connector)
- Using the remote control program from the ISAC RH control room, click on the Mini-Storage option and then click buttons for open and close to operate the door (note: it is important to verify both opening and closing functions work before attempting any remote operation).

Remote and local functionality have been tested and verified working.

It is recommended to mount the mini-storage control box in a convenient area near the mini-storage (possibly on the wall adjacent the main storage vault).

Please contact me if you have any further questions.

ITE IG1S cable end connector replacement has been finished by Roy Huang.

 The spent SiC#41 target has been placed in pail #260 and placed in spot 5B of that spent target vault. See attached PDF for details. 

 Ta#56 in pail #169 was repacked and placed into #269 and was placed in the mini vault at the back. It was 3.86mSv/hr upon removal from the NHC. See attached files for details.
