Bearings for the main storage vault door were lubricated on 2023-07-28. It is unknown when this was last done. It is suggested that this be a recurring maintenance task every two years.

Looked at SiC#45 in the hot cell. Looked very clean, no deposits on the heat shield or other components. Target also looked very straight. Only issue we saw was sparking marks on the EE side that faces the ground electrode, in several spots. This target had a bout of sparking when ramping up the protons, so I guess that was the location. Will look for matching spark marks on the ground electrode next time TM4 is in the hot cell. Forgot to take picutres...

 An electrical check was made after new target installed on TM4.

 TM4 with new target UCx#42 was connected in ITE. 

 TM4 with spent target SiC#45 was disconnected ITE  and an electrical check made right after moved on NHC. 

The TiC#5 post irradiation inspection was done on Wed. June 14 and Mon. June 19. This target didn't have any obvious issues but it didn't produce much beam. The inspection revealed that the container was quite embrittled and showed significant damage, though it was not broken. The FEBIAD grid looked fine, despite the large anode current draw (indicating that current was flowing elsewhere). The gas line looked fine though the gas injection to this target looked as if it wasn't connected. But there was a plug on the unused line, so it must have been correct. No other obvious signs that would explain the poor performance. Pictures are can be found here https://documents.triumf.ca/docushare/dsweb/View/Collection-37913

An annual electrical and mechanical inspection was performed on the SMP today by Adam Newsome, Travis Cave, Eric Lahe, Maico Dalla Valle, Antoniette Yap, and Jason Zhang as per Work Permit I2023-06-21-4. The following items were checked:

• Check condition of wiring for physical/radiation/UV damage
  • OK, no signs of significant damage
• Check for cable tray debris or damage
  • There were multiple items in the cable tray which do not belong there - misc. pieces of wood and metal... these items were not disposed of but should be in the near future
• Check inside control panel: components and wiring, labeling
  • Labeling intact, components in good condition
  • Misc. random wires pulled to check... one ground wire was loose - it was tightened
• Verify camera views
  • This was not inspected in detail but signal status was checked, and is checked prior to remote operation
• Check connectors for damage
  • All connectors OK
• Check pendant for damage and verify labeling intact
  • Pendant OK
• Lid open/close test
  • Lid was opened and close multiple times - smooth operation, no concern
  • Lid close logic was checked - OK
• Vessel rotation and limit switch check
  • Both CW and CCW limits were checked, functioning
  • No concern on rotation - chain drive, rotary limit switch, and cable reel all functioning normally
• Lubricate chains
  • Not done - should be done next year
• Inspect tensioners
  • Done - OK
• Tighten fasteners
  • Not all fasteners were checked - washers will be replaced soon so this was not deemed necessary
  • Approximately 50 washers are missing for socket head screws in slotted parts. Not safety critical but they should be replaced soon.
• Visual inspection
  • All OK

Overall the inspection was successful.

 TiC#5 moved to the spent target vault from the north hot cell. Placed in pail#279 in spot 3A, 40mSv/h when removed from NHC. See attached PDF for further details.

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.

ITE water signal interlock check including HS,EE, TA, TU, MSP. Coil1 , C-window ,2a-window, 2A tank, 2A shielding plug , 2A dump, 2A collimator  are done. All things work.

 TM4 with new target SiC#45 was connected in ITE, all TPs are running at their full speed.

 TM4 with new target SiC#45 installed has been leak checked and electrical checked on top of NHC.

 TM4 with spent target TiC#5 electric check after moving from ITE to NHC.

 TM4 with TiC#5 was disconnected in ITE and moved to NHC.

Plant group changed TCS water filters last Friday. 4 filters on resin can inet /outlet sides and filters(4 in one cartridge house)on pump return line have been changed. Triumf maintenance tags on filters have been updated. No water leak after job. The TCS TK2 water level dropped  from 20" to 16" because of the job. I will refill the level to 28" today. 

TCS:TK2 is refilled to 28".

Conditioned TM2 up to 48kV in ITW. Some sparks and current is not very stable. Drawing about 178uA at 48kV.

The annual inspection of the mini-storage vault and main storage vault was completed June 23, 2023. The following items were checked:

• Cabling and cable management
• Connectors
• Controls box - internal wiring and components, functionality
• Limit switches - functionality, wiring, mounting
• Motor
• Bearings
• Set screws
• Miscellaneous fasteners

The inspection was generally successful. A couple of minor findings were:

• Bearings for both the main and mini storage vaults must be greased. This is planned for a different day as it involves removing the mini vault's door.
• There was a small piece of metal on the track for the mini storage vault which was causing the door to "bump" over it as it passed over. This piece was removed and the door behaved normally.
• The wheel track for the main storage vault was dirty - it was cleaned
• It was suggested that the 120 VAC power cable for the mini storage vault controls box should be connectorized - this will be added to the "to-do list" for the future

MAA ASU test have been done following document 154779. All three tests in document are passed. DCR Jas has all test documents.

This test includes the functional test on TH emergency roof hatch which is located at the west end of TH roof. The hatch could be opened and closed properly from TH inside.

ITW water signal interlock check is done. All ITW water signals including HS, EE, Coil , Ta, Tu, MSP, C-window, HVC1, HVC2, 2A-dump, 2A -shielding plug, 2A-tank, 2A-window, and 2A-collimator are checked. All  water signal interlock work fine.

 Gas lines pumped down at electric room for TM2 at ITW is done, leak rate 0.0e -8 <1.0e -3 T P pressure
