Conducted PIE on SiC#44, which failed online. It had a cathode short, a target short and an anode short by the time we called the experiment off. In the post irradiation examination, two clear marks where the target legs touched the heat shield were found (see attachments 1 and 2). No marks were found to indicate where the cathode short would have been. The fibreglass sheath covering the anode wire where it passes over top of the coil was destroyed, must have been a result of sparking (see attachment 3). No other issues noticed, grid looked fine, though close inspection is difficult.

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.

 On October 22 2024 the spent SIC#44 returned from CNL was repacked in a new pail it was in pail 275 and repacked into pail 298 it was 2.34mSv/hr when removed from the south hot cell.

It was placed in the very back of the mini vault. 

 Today while I was removing the SiC#43 it was noticed that the multipin guide pin was loose.

This made it difficult to remove the target, and the multipin shoulder bolts removal was required.

With the loose pin it was not possible to attach the multipin for the target C#4.

Chad was able to tighten the multipin guide pin enough, however it became obvious that the pin could not be removed when it was attempted.

With the pin tightened, the target C#4 was installed and all checks were good.

It was recommend that once the C#4 target is removed the TM4 will need some repair to remove the multipin guide pin. 

Chad - Also it was noted that the guide pin (ITA6453) in question showed signs of plating or heat (see pictures I've added)

 TM2 with Febiad Target SiC #43 was connected in ITW. NOTE: the number of TARGET in attached picture should be #43. 

 the module was disconnected in pit and moved to NHC.

 A electrical check was done at NHC, see the pic attached with please.

 The spent target SiC#43 was moved from the north hot cell in pail #272 and place in 5A of the spent target vault. See attached PDF for details.

 While removing the SiC#42 it became apparent that the multipin guide pin had become loose again and was not allowing the target to dismount from the module.

The multipin shoulder bolts were removed and then the multipin was able to be pried off.

However the NHC manipulator were not able to reach the guide pin to remove it, which would be required before the SiC#43 could be installed.

The target module was then moved to the SHC where the guide pin could be removed and the installation of SiC#43 took place, along with the transfer of the parasitic attachment onto the SiC#43.

This problem seems to suggest that the multipin could use some redesign to ensure smoother target exchanges.

Monday morning June 20th: TM2 with SiC # 42 was moved from ITW to NHC.

Monday afternoon: TM2 with no target was moved from NHC to SHC due to 10 pin connector guide pin loose issue. The guide pin has to be moved out in SHC due to NHC manipulator configuration limit .

Monday afternoon: TM2 with SiC # 43 was moved from SHC  to ITW.

all module moves are smooth.

 An electrical check was done at SHC for TM2 with FEBIAD SiC #42 Target. 

 TM2 with Febiad target SiC#42 was connected in ITW.

On June 2 2022, while attempting to install target SiC#42 a gasket fell off the water line. I attempted to remove the target to have the gasket reattached, however the multi pin connector guide pin was loose and was preventing the target from being removed. During the attempt to remove the target it was noticed that an electrical cable in the back of the module had become loose and was dangling. The target was then secured to the module, and then the module was moved to the SHC to complete the job/repairs.

June 3 2022, containment box was removed, Einzle Lens cable reattached and tested, and the multi pin guide pin was retightened.

On June 6 2022, the containment box was damaged while lifting the containment box back onto the module.

The left rear corner of the box caught on the module and the corner weld snapped and folded the corner down about 90 degrees.

With help from Chad, we were able to restraighten the corner with a C-clamp, enabling the box to be reattached to the module.

However the 2 bolts that were on the corner that attach to the module were not able to be aligned and were not used.

The target was reattached to the module, and to save time was brought directly to ITW, skipping the conditioning station. 

 An electrical check was done at NHC, see attachment pls.

 The spent SiC#42 was moved from the north hot cell to the spent target vault, it was placed in pail #271 and put in spot 2B. see attached PDF for more details.

TM#4 with SiC#41 has been moved from the NHC to ITE.

 TM#2 moved from ITE to NHC SiC#41 removed and then moved back to ITE.

 The spent SiC#41 target has been placed in pail #260 and placed in spot 5B of that spent target vault. See attached PDF for details. 

TM#4 with SiC#40 has been moved from the east target station to the south hot cell.

 TM#2 with the SiC#39 target has been moved from the south hot cell to the east target station.
