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.

 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.

 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. 

C#4 spent target was moved to the storage vault, in pail 277. Dose rate at approximately 1 m when leaving the hot cell was 164 mSv/h. The pail has been placed in vault location 4C. See updated vault layout attached.

The following five pails were moved to the mini-storage vault today under work permit I2022-12-16-1:

• #239 (formerly vault location 7A): 1.38 mSv/h @ 1m
• #245 (formerly vault location 6B): 1.56 mSv/h @ 1m
• #264 (formerly vault location 6A): 748 uSv/h @ 1 m
• #267 (formerly vault location 1C): 708 uSv/h @ 1 m
• #268 (vault location 7C): 809 uSv/h @ 1 m

The mini-storage vault is now full and ready for transfer to F-308 flasks.

The following measurements were made on other pails:

• #211 (vault location 3C): 4.21 mSv @ 1 m
• #217 (vault location 3A): 1.05 mSv/h @ 1 m
• #246 (vault location 6C): 1.98 mSv/h @ 1m
• #274 (vault location 1A): 4.78 mSv/h @ 1 m
• #228 (vault location 1B): 3.86 mSv/h @ 1 m
• #256 (vault location formerly 7A, now 7B): 3.60 mSv/h @ 1 m
• #260 (vault location 5B): 1.46 mSv/h @ 1 m

The target index spreadsheet has been updated to reflect these changes. See attached PDF print.

The following three pails were moved from the main storage vault to the mini-storage vault:

1. #211, Ta#58 (formerly vault location 3C)
2. #217, ZrC#8 (formerly vault location 3A)
3. #228, UC#37 (formerly vault location 1B)

The target index spreadsheet has been updated.

 UC#40 was moved from the north hot cell to the spent target vault. It was placed in pail #278 put in spot 1B and was 15.6 mSv/hr when removed from the north hot cell.

Also Ta#62 in pail #256 was moved from spot 7B back to 7A where it was originally located. This pail in the future will have to be repacked due to the fact it lacks a reinforcing disc in the bottom of the pail.

 The spent UC#41 was moved from the south hot cell to the spent target vault, placed in spot 1C, in pail #231. See attached PDF for details. 

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

The test was successful.

The annual inspection of the mini-storage vault and main storage vault was completed June 23, 2023. The following items were checked:

• Cabling and cable management
• Connectors
• Controls box - internal wiring and components, functionality
• Limit switches - functionality, wiring, mounting
• Motor
• Bearings
• Set screws
• Miscellaneous fasteners

The inspection was generally successful. A couple of minor findings were:

• Bearings for both the main and mini storage vaults must be greased. This is planned for a different day as it involves removing the mini vault's door.
• There was a small piece of metal on the track for the mini storage vault which was causing the door to "bump" over it as it passed over. This piece was removed and the door behaved normally.
• The wheel track for the main storage vault was dirty - it was cleaned
• It was suggested that the 120 VAC power cable for the mini storage vault controls box should be connectorized - this will be added to the "to-do list" for the future

 TiC#5 moved to the spent target vault from the north hot cell. Placed in pail#279 in spot 3A, 40mSv/h when removed from NHC. See attached PDF for further details.

Bearings for the main storage vault door were lubricated on 2023-07-28. It is unknown when this was last done. It is suggested that this be a recurring maintenance task every two years.

The bearings on the mini storage vault were lubricated. It is suspected that this has never been done. It is suggested that this be performed every two years.

A draft procedure will be created for this job, but at a high level, this process involves:

• Opening the door fully
• Disconnection of the motor, limit switches, and cable management system
• Attachment of a lifting magnet to the door itself
• Raising the door
• Lubricating bearings
• Reversing the process to re-assemble

The entire job took less than 1 hour to complete.

 TiC #6 moved from north hot cell to spent target vault placed in pail #232 put in spot 6A and the field was 151mSv/hr when removed from the north hot cell. See attached PDF for details about spent target vault.

UCx #42 moved from North Hot Cell to Storage Vault in Pail #282. Placed in slot 6B. Tray 6 is now full. Pail measured at 34.9 mSv/h at ~1 m upon removal from the hot cell. See attached updated spreadsheet. 

Upon attempting to lower Pail 211 into their tile hole, CNL encountered issues with the pail getting stuck. They shipped the pail back to TRIUMF and requested we perform an investigation. The investigation report is attached.

The pail contents must be re-packaged into a new pail.

Note: the F-308 is currently sitting in the Meson Hall warm cell at approximately 250 uSv/h at 0.5 m.

Dose for primary worker (Chad Fisher) who inspected the cable, unbolted the flask lid, and handled the pail briefly: approx. 104 uSv

Dose for secondary worker (Danka Krsmanovic) who swiped the pail and flask to check for contamination: approx. 70 uSv

 The spent Nb#11 target was removed from the south hot cell and place in the spent target vault. It was placed in pail #283 and place in spot 7B is was 65.7mSv/hr upon removal. see pdf for further vault details.

 All 20 targets in the vault were measured. The target spread sheet updated. See attached PDF for details.

The following four pails were moved from the main storage vault to the mini storage vault, to stage for shipping in Jan. 2024:

1. Pail 260 (SiC#41), Tray 5B
2. Pail 271 (SiC#42), Tray 2B
3. Pail 246 (Nb#10), Tray 6C
4. Pail 265 (UCx#36), Tray 2A

There is current one open slot in the mini storage vault which is planned for the Ta#58 target (formerly in Pail 211, to be repacked in Dec. 2023).

Target Index spreadsheet updated.
