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:
  • Phone not working at North hot cell operator station
• Target Hall:
  • Uncertain if NHC and SHC ventilation pressure gauges have recently been inspected

Action has been taken on all deficiencies.

 Resolution comment / Commentaire de résolution:

     Fixed issue by changing patch cord that was connected to the switch from patch panel.

 5 shielding blocks are transferred from ITW to ITE, Target Area is secured again after moving.

TCS water system has been started for functional test. System parameters including  pressure, all temperature sensors, flow rate sensors, resistivity are ok. I will watch on chiller CP1/2/3 in rest of the week and make sure chiller CP1/2/ 3 auto stage in/out work fine.

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)
 

TM3 was moved from silo to SHC with no target. Move successful.

TM3 was moved from SHC to TCS with UCx#47. The move was smooth.

TM2 was moved from ITE to SHC with Ta#68 target. During the move, a railing was lightly bumped by the corner of the module - no obvious damage or issues have been observed. Otherwise, the move was smooth.

TM3 was moved with UCx#47 from TCS to ITE. 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. 

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

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.

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.

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.

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.
