Subject: Modifications to wire ropes for pails within existing F-308s 

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.
