Note: Ta#68 had a difficult install. See E-log ID# 2698 for more info 

First look:

• Containment box cover looks the same as previous (See:ID: 2697)
• Target shows large amount of soot-like deposits (See photos for locations)
• Deposits seem to have been left on parts of the service tray as well ie.: Multipin connector 

Removal:

• Removal was smooth
• Water-line bracket fixing bolts seemed loose even before I put a tool to them 

Eyes of sides:

• Better photos of where deposits are 
• Everything else seems normal 

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

TM2 with spent target TA#68 was disconnected  in ITE and is being moved to SHC. All water lines are purged for module storage.

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

Handover from TPO and inspection

• Completed
• Some modification to the center Inner-Outer conductor had to be made (hole enlarged as tab was slightly short)

Target Insertion:

• Successful 

Target Mounting:

•  Upon fully seating UC#47 on service tray locating pins, the gas line VCR gasket came off 
  • Operator doesn't have line-of-sight to this area, so there has to be healthy clearance (Foreshadowing) 
  • Gas line VCR gasket reinstalled using manipulators  

• 2nd seating of UC#47 on service tray locating pins, the gas line VCR gasket came off again
  • Some alignment interference with the gas line coupling is the cause of the gasket falling off during placement (photo attached)
  • Gas line on service tray was loosened, raised to highest position and fastened (Photo attached)
  • Failed to re-install VCR gasket (Plastic separated from gasket material)
• Target removed from Hot cell to reinstall gaskets and make modifications to the gas-line coupling
  • Gas line coil plastically deformed to give less of a spring action so the coupling can stay down under friction until it is time to couple
  • Target carefully inserted into hot cell without disturbing spring/friction of gas-line coupling. 
    • This had to be repeated several times. Once for the waterline gaskets coming off, and a few other times to insert the target/tray without disturbing sprung coupling
• Target mounted without issue after the above steps successfully 

Gas and Water Services:

• VCR connections coupled 
• Leak test passed
  • leak test faster today because module had been left in silo for a long time to dry out. 
• Gas line no-longer needed, so was not checked

Electrical Services:

• Conductor bolts installed
• All bolts (including mounting bolts) checked for fit with mirror
• Coil conductor bolts torqued to at least 130inch-lbs 
• Electrical test completed 

Containment box panel reinstalled 

Cleared area around module for craning out. 

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

An electrical check and leak check had been done after new target UCx47 was installed on TM3 in SHC. see attachment pls.

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

 Shielding blocks have been moved from ITE to ITW and MAA is secured.

"Nov. 8, 2024 - Aaron Tam 
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)
 

 TM4 with new target UCx#46 was moved from TCS to ITW and has been re-connected right after. see attachment pls.

Tong cable snapped when attempting to remove multipin connector bracket 

Assistance from Chad required for the rest of procedure 

Tic#9 was loaded into Pail#299 

• Along with fixing and conductor bolts (no other material was loaded)

UCx#46 Target handover from TPO 

Target insertion: successful 

Parasitic Install: All Parasitic targets left off target

• Left side In-beam array type parasitic install attempt #1 
  • Parasitic assembly is too thin/studs too tall for the socket nut to fasten onto target. Stud protrudes through the length of socket section, not allowing tool to insert 
  • previously a 3/4 spacer was used to give space for thermal couple to enter 
  • Install of 3/4 spacer was difficult because it does not hold its shape when handled (pivots around 1/2 ad 1/4 portions) 
  • With spacer installed, parasitic assembly is too thick for socket nuts to fasten onto studs. 
    • It may have been possible to back out studs to use, but left off in the interest of time UCx is exposed. 

• Right side In-beam window type parasitic install
  • Similarly to Left side, studs were too short for install, studs could be backed out, but was left off in the interest of time UCx exposed

• PEEK seal parasitic targets were left off as per schedule, and will be leak checked at another date (after tong cable has been repaired) 
  • Order of PEEK seal locations preserved and follows order as seen with target installed (Photo attached)

Target install: successful 

Leak Check: Successful 

Electrical Check: Successful 

• Initially failed due to wiring diagram being different between production wiring diagram and electrical test sheet

Containment box panel closed 

 TiC#9 was placed in Pail 299 in spot 8A of the vault and was 92.1mSv/hr when removed from the south hot cell. See attached pdf for full vault details.

TM4 with UCx46 electrical and leak check at SHC is done. Everything is good.

November 5, 2024 - Aaron Tam

TiC#9 HP-SIS removed from TM4

• Top left fixing bolt shows signs of heating on it (Comparison photos attached Bolt_profile.jfif  & Bolt_Tops.jfif)
• Location and orientation of darker bolt (Darker_bolt.jfif)

Parasitic Targets Removed

• Left target has residue left from ablation 

See photos attached for detail 

 David made electrical check right after TM4 is moved from ITW to SHC. see attachment pls.

 TM4 with spent target TiC#9 was disconnected in 29-10-2024 and it is being moved from ITW to SHC.

 On October 22 2024 the spent SIC#44 returned from CNL was repacked in a new pail it was in pail 275 and repacked into pail 298 it was 2.34mSv/hr when removed from the south hot cell.

It was placed in the very back of the mini vault.
