Tong cable snapped when attempting to remove multipin connector bracket"

Repair went as follows:

• weighted clip attached to tong return side to tension/keep tapes on pulleys
• Manipulator was pinned from both sides (Pinning from master side first makes it easier to position slave side)
• clamps were used to suspend all tapes and cables near the relay bracket 
• extension tube limit clamps were moved to the top to stop it from dropping when Z motion tapes disconnected
• Z motion tapes/tension adjusting screws taken off master carriage and suspended with equalizing weight ~10+ lbs)
• Extension tube limit clamps and extension tube lowered give space to expose multiplier later 
• Wrist joint and handle removed as a unit 
• extension tube to multiplier screws taken out
• Extension tube raised to expose multiplier - using extension tube to wrist joint positioning clamp to keep it in place 
• Old cable removed
• new cable installed

installation in reverse with spare master handle 

Notes:

Spare master wrist joint was missing gears that connect wrist drums 

• this had to be disassembled and installed with gears from old wrist joint

Handle ratcheting pawl spring was not oriented properly, so this had to be disassembled and reinstalled properly (in the process one spring was lost Part#: A-5800)
 

 November 27th, 2024 - Aaron Tam with Farran & David 

Parasitic Assembly Leak Check (Aaron, Farran, David)

-Note that the furthest upstream (right of the target) parasitic top cap screws had been loosened and retightened in error when attempting to remove it off TiC#9

-This puts this data point into question 

-Leak check starting from upstream to down stream 

-First parasitic had no leak 

-Second parasitic had some leak 

-Third parasitic was not pumping down at all

-First parasitic checked on test hose again with same success

Parasitic Dis-assembly (Aaron) 

-First parasitic had good tension in all 3 screws

-second parasitic had 2 screws with a perceptible breaking-loose of the screws, but one was imperceptible 

-Third parasitic had lower (than first parasitic), but okay tension in all 3 screws 

In an attempt to move the PEEK seal into a safe spot with tweezers, this one was accidentally sprung across the hotcell in the direction of the tool port 

A lengthy attempt to find it was conducted, but no PEEK seal was recovered 

This may effect our ability to do work during hot cell entries coming up. 

PEEK Seal extraction (Aaron, Farran) 

-A labeled bag was inserted into the hotcell via the tool port and onto an existing tray in the Hotcell

-PEEK seal placed inside bag, placed back on tray, and moved back to the tool port for extraction

-With tool port open, the draft was able to push the bag across the lift table. Changing the cross section exposed to the draft works to keep the bag from moving

-Farran used picker to extract the bag into the tool port where he wiped and placed into separate bag.

-This process was repeated for the second PEEK seal 

-Bags were wiped and swiped, put in another bag, swiped and brought over to Hot cell Service area Lab 

 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 

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. 

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.

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).

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.

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.

 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 .

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.

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.

 The spent UC#47 was moved from the south hot cell to the spent target vault placed in pail #302 in spot 1C of the vault, it was 24.5mSv/hr when removed from the south hot cell. See attached for vault details.

Today (2025-01-20), six flasks were loaded in preparation for shipment with the following targets: C#4, TiC#5, Ta#64,Ta#62, Nb#10, SiC#44

Some of the pails (256, 273, 279, 277) required replacement of the wire rope cable with new style, 30 ft length, as requested by CNL. A lifting label was also applied to these pails. Some of the pails (295, 298) already had the appropriate cable and lifter label.

At the time of writing this log:

• The second crimped lifting loop has not yet been applied to each pail.
• The locks have not yet been applied to the flasks.

The mini-storage vault is now EMPTY. The mini-storage vault has been swiped and checked for contamination.

The target index spreadsheet has been updated (attached).

ITW/ITE pit general annual cleaning up were done. all concrete floor and TM equipment surface are vacuum  cleaned. HV cage inside and blue nylon insulators were wiped by paper.

 David and I cleaned both cages in ISAC1 electric room, all done.

A parasite target has been transferred from SHC to NHC. It is a job to reduce SHC field for coming SHC entry job. The transfer is successful.

ITE and ITW water system paddle wheels and coils on all flow sensors in pits have been replaced. It's a SAS job.

Fields in the hot cell were checked using a pole monitor. Field approximately in the area someone would stand to repair manip. is 3.8 mSv/h

Hot item found! Bag with extraction electrode and high current fasteners from an online target.
