Based on a request from CNL (attached), modifications were made to the wire ropes protruding through the tops of F-308s to add a crimped loop which acts as a lifting feature. Tests were performed (report attached) on 10 sample units to validate the strength of these loops, since each loop could not be tested in-situ once the pails were already packed in F-308s. CNL has reviewed and approved the test report.

Wire ropes within the following F-308s, which were staged for shipping as of June 20, 2023, were modified to include the lifting loop:

1. 06
2. 13
3. 15
4. 16
5. 19
6. 20
7. 21
8. 22

Each lifting loop was:

• Crimped according to the same procedure, using the same parts and tools, as the 10 sample units
• Measured using a tape measure to confirm the 3" size specified by CNL
• Checked using a go/no-go gauge provided from the crimp tool manufacturer
• "Pull tested" by hand as a quick check to confirm the crimps were successful (not a quantitative and official test, but a secondary qualitative "feel good" check)

As of the time of writing this e-log, TRIUMF believes these F-308s to be ready to ship.

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.

Isaac and Chad disengaged the slave end of the manipulator and performed a slave removal through the slave removal roof hatch. This is part of investigation into a 'Z' motion tape that is "rubbing" on its drum on the master side of the manipulator during manual 'Z' retraction of 'Z' extension.

This also was the first test of the concept of removing the manipulator slave through the manipulator hatch that was built into the roof.

The lifting bail on the slave end of the manipulator was not centered to the hatch as per design but this did not compromise the procedure at all and the procedure otherwise followed the design intent.
