Over the course of September 9th - September 13, 2024 a CRL manipulator technician carried out the following manipulator maintenance:

NHC operator side arm #9763 (right side installed position) - Inspection and re-tensioning of tong cable prior to re-installation (was a little too tight). Operational.

E-HD clean spare #8015 - repaired stuck manual 'Z' motion - removed one rouge 5-40 screw that had been dropped inside remote end during 'Z' motion cable run through in 2017, found that related 5-40 screws from the cable end clamp were not tight and therefore proud and also jamming. Complete tape replacement and tensioning. This manipulator is fully back to operational status other then needing some screw for the air restriction on the remote end.

E-HD "dirty" spare #7985 - inspection and evaluation of parts on the operator side require to return to operational status. Wrist and handle reassembled (all parts of wrist and handle accounted for) Ball and socket joint at and of motion lock replaced (parts were on hand already) as well as tape motion lock assembly (parts on hand already). This arm may be missing a relay or two. Remote side still bagged with unrecorded issue (suspect it is only a broken tong cable) this will be put in the maintenance schedule for earl 2025.

NHC operator side "spare" arm #9351 - Damaged 'Z' motion tape replaced. Tensioning. Operational once 'Y' motion linear actuator re-installed.

On Friday, September 6, 2024 Model 'N' remote arm #9352 was removed from the NHC right side installed position to investigate  an ongoing issue with the tong motion circuit (no motion on the remote side when handle on operator side operated).

Inspection revealed that the tong cable on this arm have hopped its cable drum and rapped around the shaft of the cable drum. As well, the tong cable had hopped a lower pulley and was jammed between the pulley and casting of the pulley housing. These issues were corrected and arm#9352 was reinstalled onto the right hand position. This repair resolved an ongoing tong motion system stemming from November 2023 described below.

initial tong motion problem from November 2023 when the tong system jammed, operator side arm #9763, remote arm #9342.

Remote arm #9342 was removed and replaced with arm #9352 as it was suspected there was a hopped cable on #9342. Upon removal it was confirmed the tong cable on remote arm #9342 had indeed hopped the pulley. After installation of the "spare" remote arm #9352 that hAd not been installed since previous servicing and should have been completely operational, it was found the tong system still did not work properly.

Upon thorough inspection of operator arm # 9763 it was found that the tong cable was prematurely reaching the end of its travel on its drum causing the inability to activate the circuit. The tong cable was reset on its drum as per manufacture's specs with one full cable rap on the drum and one full pretension wrap of the tong drum spring.

Although this resolved part of the problem and allowed a full squeeze of the operator handle it did not result in transfer of motion through the system to the remote end.

Further investigation continued, separating the operator side arm from the seal tube and testing the seal tube and operator side arm independently. Both systems worked fine independently, pointing to a potential problem between the seal tube and spring loaded coupler on the remote arm.

Remote arm #9352 was removed and couplers visually inspected and end of seal tube on the hot side was inspected and found that the pin in the end of the shaft on the tong circuit was not installed symmetrically which could cause uneven pressure on the spring loaded coupler of the remote arm. This pin was adjusted and all pins on the hot side of the seal tube were dimpled and loctite applied as a precautionary measure.

This still did not remedy the tong motion problem. These led to the September 6, 2024 removal and repair of remote arm #9352. This arm had previously been serviced by a CRL technician in December of 2017 and had not been installed or used since and should have been in operational status. It is still not clear why it was not.

 

 

  2680   Thursday, September 12, 2024, 14:12 Adam NewsomeWaste Package/ShipDevelopment SiC#44Failed waste emplacement at CNL: Flask #22, Pail 275 (SiC#44)

On 2024-09-12, CNL reported difficulty with lowering Pail 275 from F-308 flask #22 into their tile hole. The four other pails associated with this shipment were successfully emplaced. It is suspected that the issue was related to a kink in the lowering cable, causing a jam during lowering. This was observed approximately 1 year ago.

Discussions with CNL to learn more about the root case are ongoing, and this e-log will be updated when more information is learned. It is expected that this flask will be shipped back to TRIUMF and the pail will need to be repacked.

 

Update 2024-09-12: email from A. Swan at CNL: "4 of the 5 flask were emplaced successfully with F308 #22 SiC#44 having an unsuccessful pull test and left within the flask."
This is the extent of the information they have provided and is not sufficiently helpful to determine what the issue is.

 

Updated 2024-10-03: an investigation was performed (work permit C2024-09-26-10). It was determined that the root cause of the issue is attributed to an assembly error - the cable was incorrectly routed through the holder part. See attached report for full details.

  2679   Wednesday, September 11, 2024, 13:38 Adam NewsomeNorth Hot-CellRepair  Spare Manipulator - Y-axis motion not functioning

Update 2024-09-12: C. Fisher confirms this is actually normal behaviour. The Y-axis motion is inhibited when X and Z are in a certain configuration, which was true when the manipulator was mounted on the wall in storage position. Non-issue. A note about this has been made in the operator manual.

 

It was observed today that for the spare manipulator (Model N, Serial 9351), the Y-axis motion was not functioning. X motion and Z motion are functioning as expected. Note that the Y-axis linear actuator was recently replaced and successfully tested and has not been used since the replacement (see e-log 2422).

The following information was determined from troubleshooting:

  • X motion functioning correctly
  • Z motion functioning correctly
  • Y motion selection functioning correctly - the indicator light on the operator control box lights up to confirm Y is selected, and the relay on the main control board which selects the Y axis toggles, as expected
  • Y motion motor contactors do not function as expected when toggling in either direction. Note that these contactors are shared in common with the other two motion axes, so they are functioning correctly and presumably the motor controller itself is as well, since the other axes work.
  • Most likely, because of the above reasons, there is an issue with the inhibit signal that is specific to the Y axis. The inhibit signal which runs from the main control board to the motor control board is shared in common with all motion axes (same for the two direction select signals). It is suspected (not yet confirmed), that the microcontroller is not outputting the inhibit signal as it should be. This is not due to a limit switch related issue because the Y axis does not have limits. Troubleshooting this has been difficult because the schematics do not show the full extent of the circuitry.

Further troubleshooting steps:

  1. Check inhibit signal functionality - is it working for Y axis?
  2. Check direction control signal functionality - are they working for Y axis?
  3. Swap motor select wires to "trick" the microcontroller into thinking it is running a different motor, to further isolate the issue.
  4. If required, swap the entire main control board with another manipulator's, to see if the issue is related to the circuitry which is not described in the schematics.

At the time, this issue is not deemed critical because this is a spare unit.
