Sic#39, Ta#59, C#2, UC# 32 & 30 have been moved from the spent target vault to the mini vault. See the attached pdf for details of the vaults.

5 pails were moved from the mini-storage vault into F-308's

At one point during the loading the mini-storage vault door would not close. Cause was a blown fuse, which was replaced and operations were able to continue as usual. Possible reason the fuse blow was a tilted pail that may have become jammed between the tray and the roof of the mini-storage vault. 

[Edit 2022-12-01, Adam Newsome]: the pails which were removed were: 220, 227, 233, 235, 238

 UC#37 was placed in pail #228 and place in spot 1B it was removed the north hot cell. See attached PDF for more details of it and the vault.

An annual electrical inspection was performed on the SMP today by Travis Cave and Nadia Jorgenson as per Work Permit I2022-06-30-2. The following items were checked:

Electrical Inspection of Safe Module Parking:

• Check condition of wiring for physical/radiation/UV damage
  • OK, no signs of damage
• Check for cable tray debris or damage
  • Some objects stored in the cable tray but nothing concerning, no damage noted
• Check inside control panel: components and wiring, labeling
  • Labeling intact, components in good condition
  • Wiring in good condition
• Verify camera views
  • Checked, no issues
• 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
  • Centre, CW and CCW limits were checked, functioning

Still to be done – Mechanical Inspection:

• Lubricate chains
• Inspect tensioners
• Tighten fasteners
• Inspect components during rotation - chain drive, rotary limit switch, and cable reel etc.

An annual mechanical inspection was performed on the SMP today by Dan McDonald and Nadia Jorgenson. The following items were checked:

• Lubricate chains
  • Not needed
• Inspect tensioners
  • No issues found
• Tighten fasteners
  • A few slightly loose, most are in need of washers, see attached pictures
  • Could use some shims in a few places, see attached picture
• Inspect components during rotation - chain drive, rotary limit switch, and cable reel etc.
  • No issues

Dan lubricated components on the target storage vault (This was an outstand task from annual inspection). No issues on the main storage vault but we were not able to lubricate the mini storage vault because the position of the grease nipple on the fittings makes them inaccessible, see attached pictures. All four should be replaced with 90 deg fittings. 

 The spent SiC#42 was moved from the north hot cell to the spent target vault, it was placed in pail #271 and put in spot 2B. see attached PDF for more details.

 The spent target SiC#43 was moved from the north hot cell in pail #272 and place in 5A of the spent target vault. See attached PDF for details.

 The spent Ta#64 target in the north hot cell has been packaged and placed in the spent target vault. Pail#273 spot #5C 86.6mSv/hr upon removal from the north hot cell. For detail on the vault see attached PDF.

ITE:ANODE supply reading strange currents - 17mA with the power supply on and no voltage. Checked anode circuit from electrical room:

Anode wire in electrical room shows 0L at 250V

Circuit with 50kOhm resistor mostly looks good (49-52kOhms) but a couple times read 28kOhms, no idea why. Tried jiggling all cables, unplugging and replugging and everything looks fine.

But power supply still seems to be giving out signal for 17mA readback. Decided fastest to swap with TCS power supply and troubleshoot this one on the bench.

The motor cable for the storage vault was replaced as the old one was showing signs of wear. The U-track that the old cable ran through was also bent as a result of being hit.

In the process of replacing the cable, an e-chain was installed for cable management purposes. Mounting brackets were modified and a new U-track was installed as well. The new hardware is more robust than what was previously installed.

The vault door was opened and closed multiple times while observing the e-chain - everything behaved as expected. The system is operational.

Solidworks model IRH0189 is updated to show the changes

 The spent target UC#38 was packed into pail #274 and placed in spot 1A of the vault. It was 33.3mSv/hr when removed from the north hot cell. See attached PDF for more vault details.

On 26/Sept/2022

Chad disassembled the right operator side manipulator, and noticed that gears in the handle were quite tight especially when compared to the left operator side manipulator. 

Once a dry grease was added, and the handle reassembled all seemed to be in working order.

There was noticeable wear on a shaft and Chad has suggested to order some spare parts for the wrist and handle. 

Myself and Maico were able to top up the NHC window oil.

The oil was filled through the expansion tank

- the Nitrogen line closed and the Nitrogen pressure valve was disconnected to ensure that no oil would go in to them.

- the pressure relief valve was disconnected to act as an air bleed line while we filled the oil

- with a funnel we slowly added the oil until the oil level could be read, showing about half full

- about 1.5 liters of oil were added

- once filled the Nitrogen line was reattached and the pressure was returned to recommended level 

- the remaining oil was returned the RH shop

Now the oil level will be monitored, which will help identify if there is any leak in the system.

A fully built steerer sub assembly ITA2826 revision E was boxed and sealed and put on rack storage in ISAC B2 South Hot Cell area. It is contained in a blue bin and green tag. 

It is advised if this assembly is used, it should be inspected for damage before using in a source tray.

A modification was made to integrate the hot cell's lift table into the E-stop circuit. See work permit I2022-10-07-1

The E-stop mounted on the right side of the small enclosure adjacent to the operator station will now serve to stop the lift table's up and down motion, as well as the turntables up/down and CW/CCW motions. Functionality was checked by B. Webster (electrical services) and A. Newsome.

Note: it is recommended next time there is a hot cell entry to inspect whether or not the limit switch specified in the schematic is actually installed. The schematic should be updated to match the drawing.

Redlined electrical drawing photo attached to this e-log, and the paper drawing is left inside the lift table's control box. The schematic will be revised based on the redline updates, likes as part of work request #6342 (to integrate this drawing into the turntable controls drawing package).

 Spent target move done. The SiC#44 was moved from the north hot cell to the spent target vault. It was placed in pail#275 and placed in spot#4A. It was 42.6mSv/hr when removed from the north hot cell. See attached PDF for further details about the vault.

Please note we will only have two free spots in the vault at the start of the running period after the winter shutdown 2023.

During the last ITE run with the SiC#44 target, the ITE:TBHT controls card was fried twice. The first time we put in our spare, and the second time we just continued to run without controls readback. For the C#4 run starting Oct. 19, we used the conditioning station supply. As soon as one of the other supplies is fixed, we will install it in the conditioning station. The equipment list (https://triumfoffice365-my.sharepoint.com/:x:/g/personal/cbabcock_triumf_ca/EQPffP4p1P9JqEDWIHGRPfsBVDSQjMCv-M8ZNg4ngkyGHw?e=fnLVYe) tracks these movements.

 The spent UC#39 target (pail #276) was removed from the north hot cell and place in the spent target vault (spot 4B) it was 14.4 mSv/hr when removed from the north hot cell. See attached PDF for further details. 

Did the PIE on UCx#39-IGLIS on Thursday Nov. 2 2022, couple pictures uploaded to docushare. Did not remove the target, just the heat shield cover.

Final electrical check on the module showed a dead short from TGHT/TBHT to HV common, which we did not see online. Seems like it must have occurred after ramp down? It persisted on the target after we removed it from the module. We couldn't find any obvious contact points, because it seems it did not happen while current was running in the target. Possible locations are the bottom support leg for the TBHT and the top of the right side target leg, though it was difficult to confirm with the camera.

Otherwise the only thing to note was a blacker-than-usual spot on the inside of the Cu heat shield, downstream in the proton direction.
