TM3 UCx#47 after operation electrical check  is done at SHC. The result is normal. See attachment.

 TM3 with spent target UCx#47 was disconnected in ITE and will be moved to SHC.

UC#46 was placed in pail# 301 in spot 1B and was 26.3mSv/hr when removed from the SHC. See attached PDF for vault 
details.

 SMP:MP1 is started with SMP BV1 is opened. SMP is under vacuum for TM4 storage during shut down.

ITH:MP1 is deteriorating by watching on ITH:CG1 and CG2 readings and investigation in pit. A fault 17644 has been issued. this pump will be replaced in March when general fielding in vacuum pit is reasonable for the job.

UCx#46 removed from TM4 and placed into a pail back-filled with argon. Nothing visually unusual; no issues.

ITE primary and secondary vacuum vessel leak check for 2025 shut down have been done. No leak.  The TM3 waterlines helium pressure test will be done at TCS when module is there.

 TM4 WITH UCx#46 was disconnected in 2025-01-02 in ITW. Forms attached.

 Five shielding blocks are moved from ITE to storage area ( one of them is sitting on B2 as limit of room) for target stations maintenance in 2025 winter shut down .

ITW primary and secondary vacuum vessel leak check for  2025 shut down has been done. Also,TM4 internal water line helium pressure test has been finished.  Both results are normal. There are two small old leak on EXit 1 and Exit2 module top plate  o-ring under 1Xe-8 atm.cc/sec which we knoew in past years test. resin spray on leak  area reduce the leak ratee below 5Xe-9 atm.cc/sec. No concern on these small leak.   See attachment  for detail results.

A safety walkaround was completed for the ISAC Hot Cells and Target Hall Areas.

The resulting spreadsheet can be found on DocuShare as Document-242733.

Main deficiencies identified:

• Hot Cells:
  • NHC right manipulator gripper stuck (known, repair planned)
• Target Hall:
  • 50% of overhead light bulbs burnt out (David Wang contacted Electrical Services to rectify)
  • One RH camera for target pit not working (Travis Cave notified)

Action has been taken on all deficiencies.

An informal inspection of the main Pail Handling Tool was performed today as the final one for the year. Note that the main formal annual inspection was performed June 18, 2024 for this year.

The attachment to this e-log serves as a record of all inspections for this tool throughout 2024.

The spare tool was not inspected as it was not in service this year.

Five pails were transferred from main vault to mini vault. Note that there was already one pail in the mini vault, so at present there are six pails staged for packaging into F-308s.

Nb#10, Pail 295, Tray 4A
C#4, Pail 277, Tray 4C
Ta#64, Pail 273, Tray 5C
Ta#62 with wire scanner, Pail 256, Tray 7A
TiC#5, Pail 279, Tray 3A

The target index has been updated accordingly (see attached but note that the summary does not reflect the sixth pail).

 5 Shielding Blocks have been transferred from ITW to ITE. MAA is secured after moving.

Ta#68 spent target was moved in Pail 300 to storage vault location 5A. The dose rate measured at the South Hot Cell was 429 mSv/h at 1m. The target index spreadsheet has been updated and the current vault configuration is attached to this e-log. At this time, the storage vault is getting quite full - it is planned to remove five pails in January 2025.

December 5, 2024 - Aaron Tam w/ help from Chad, Peter and Adam at the Crane  

Hot Cell Prep:

• Tools organized, working space cleared, spot for clean tool to sit placed, Air tool is open and spinning clockwise for tightening 

Loading:

• Ta#68 was loaded into pail# 300
• PEEK seal parasitic assemblies loaded (PEEK seals were removed in ID: 2724)
• Farran had some old samples that also went in (More details to come when Farran sends the info)

Lid/latching:

• This went smoothly

Bail attachment:

• Some difficulty in attaching the Lifting Bail, but went on smoothly with the help of Chad

Notes:

• One of the PEEK seal parasitic Target assembly lids was missed in the loading. This will have to be loaded next time. 
• All parasitic type targets remain in the yellow container shown in photos below. 

 Abstract:
This target has seen some irregular beam patterns 
Possibility that the beam hit the walls of the target tube or even the cooling fins
This PIE we want to investigate how the irregular beam physically affected the target 

Related ELOGS: 
ID: 2728
ID: 2698

PIE was performed by Aaron Tam, Directed by Aurelia Laxdal, Observed by Lucas Backes, Special help from Chad Fisher 

External views:

• Windows are clear of any irregularities 
• More pictures of this can be found in RH-ISAC E-log 2728

Internal Views:

• Heatshield internal
  
  • Some discolouration from heat and soot deposits.
  • This seems to be fairly clean to normal amounts - not concerning 
• Target tube
  • tube is bent with the middle higher than the sides
  • Target tube was not removed 9/64ths allen wrench could not be located for this operation 
• Target tube Exit
  • Heatshield windows were punctured to reveal the target tube entraces/exits
  • Entrance is waterline side (ITE)
• Extraction electrode parts were removed from the back off the target
  • These parts look normal
  • some of the extraction electrode would not pull out due to tight fitting parts and the investigation stopped here.

Conclusion: Target physical condition is normal as far as we could investigate 

TM2 was remotely moved from the South Hot Cell to SW Silo. Reading at SHC = 89.8 mSv/h. The move was smooth.

all water lines on TM2 have been purged. Refilled them(except HS ) with 60psi nitrogen for module silo storage before next year using. 

TM3 with new target UCx#47 was connected in ITE right after be moved from TCS.
