Entry  Wednesday, January 29, 2025, 11:39, chad fisher, North Hot-Cell, Repair, , , Model N Remote Arm #9342 Tong Cable Model_N_Pulley_3D.JPG

Model N remote arm serial #9342 tong cable has been un-jammed from between pulley 3D (see picture) and casting (this is an ongoing issue with #9342 and 9352) and cable restrung and exercised to check motion. Tong system is now functional but exhibits excessive slack. Next step will be to check tension of the elevation/twist cables and adjust the pulley block if required (this pulley block houses both the elevation twist cable pulleys and the tong cable pulley 3D which is the site of the persistent cable hop)...I suspect adjusting the tension here will at least slightly improve the slack. In addition I will also investigate repositioning the tong drum screws (the procedure used to adjust the tong opening).

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).

A complete TM3 electrical check at TCS under good vacuum has been done. Pin 14 to 60KV only has 8K ohm on ohmmeter check , and it's about 2Kohm @250V Megga. It's low in resistivity. The pin 14 is for thermocouples only so no big concern.  The rest things are good. See attachments.

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.
