Wednesday, January 15, 2025, 12:57, Albert Kong, Hot Cell 1, Development, APTW Front End Service Tray Flexible VCR Line Exchange Testing  
|
Removal and replacement testing of the stainless VCR lines extending from the HVFT to the piston modules and FE plate is documented in this ELOG.
Exchange of the FE plate water connector lines is documented in a ELOG #79. Exchange of VCR gaskets in the permanent joints is given in ELOG #83.

Wednesday, January 15, 2025, 13:23, Albert Kong, Hot Cell 1, Development, APTW Front End Power Busbars Stabuli Connector Exchange
|
We successfully performed a removal and replacement of a power busbar stabuli connector on the front end plate where the HTV connects to:
The middle-lower connector was tested as the others are more straightforward to work with.
It may be a good idea to use
a 3D printed jig to wedge into the connectors without damaging the flexures/pins.
A longer hex bit on the hot cell torque tool would greatly |
Tuesday, November 19, 2024, 15:38, Albert Kong, Hot Cell 1, Standard Operation, APTW Front End Moved into Hot Cell 23x
|
The APTW front end was moved into the hot cell, on the lift table, following procedures outlined in Document-244862.
The mock-up frame was transferred from the east turntable to the west turntable above the front end. The east turntable is covered with the aluminum
plate. During covering we accidentally broke the o-ring for the turntable plate flange. The new o-ring seal should be made ~1" longer in circumference |

Feb 13:
The 'hanging' VCR joint on the driver side was successfully exchanged by hand:
The adjacent HV shielding had to be removed to do so
Access to the screws on the shielding is limited so likely the use |

The HV shield covering the beam dump, on the peripheral side of the FE plate was taken off an on successfully with the manipulators: |
Wednesday, January 15, 2025, 12:57, Albert Kong, Hot Cell 1, Development, APTW Front End HTV Water Connector Exchange Testing    
|
The four water connections on the front end plate of the APTW that will connect to the HTV were tested for replacement with the manipulators:
The pin on these connectors were fairly easy to remove and replace with the old pin detent tool.
The pin detent tool could
also be used to manipulate the water lines while protecting the sealing face.
The horizontal VCR joint on the DRIVE BEAM CONE (ATA3674) could |

Testing completed:
Removal and re-insertion of 2x multi-pin coupling cable for HTV (see pictures, left most and right most, middle had no wire at the time).

Tuesday, November 19, 2019, 10:31, Adam Newsome, T-Hall Crane, Repair, 900VFD Encoder Board Replacement    
|
An issue arose in which the ARIEL crane hoist could not be moved. It was determined that the East and West drums were out of synchronization (by more than
0.2 m, which the limit) and the encoder board inside the 900VFD had failed.

Friday, November 29, 2024, 15:23, Adam Newsome, Hot Cell 1, Maintenance, 1000 kg crane: y axis position display not functioning
|
After a recent power cycle, the y-axis referencing was lost for the 1000 kg crane. The position readout was also incorrect, somewhere on the order of
> 30,000 mm. On 2024-11-29, A. Newsome re-referenced the y-axis. The position readout correctly reset to zero, and both +y and -y motion is functioning
correctly, but the y-axis position readout on the HMI constantly displays 0 and does not change. To be investigated. |
