Entrance Module was moved from South Hot Cell to ITW Station.

Note: weight of entrance module, as shown via overhead crane's load cell, is 14,900 lbs.

TM2 has been moved from ITW to the South Hot Cell.

Reading at ITW: 114 mSv/hr

Reading at SHC: 85 mSv/hr

C#2 has been moved from the south hot cell to the spent target vault. It is in spot 8A of the vault in pail # 235 and was 185 mSv/hr upon removal from the south hot cell.

The Target Index spreadsheet has been updated on DocuShare.

TM2 has been moved from the Conditioning Station to ITW. 

TM3 has been moved from the Silo to the South Hot Cell.

TM3 has been moved from the South Hot Cell to the Conditioning Station. No containment box.

TM3 was remotely moved from the conditioning station to the South Hot Cell. No containment box.

The Target Hall Crane has been shut down in preparation for the power outage tomorrow (Dec 22). Power will be restored on Dec 23.

Dec 23 update: power has been restored. The crane appears to be in working condition as there is no fault indicator on the PLC.

TM3 was remotely moved from the South Hot Cell to the conditioning station. No containment box.

The crane pendant for the main hoist was upgraded to a FLEX EX2 style pendant by Canco Cranes. The installation work was performed by Matt at Canco, supervised by Tom Kauss, David Wang, and Adam Newsome. Installation work was performed in two phases since the initial installation did not provide adequate range and an antenna issue needed to be resolved (I2021-01-14-1, and I2021-02-16-1).

Items installed include:

• New pendant
• New antennae
• New receiver box, mounted on main crane control panel in the crane control room

The old receiver control box will be kept for some time in case there is a need to revert to the previous system for some reason.

The new system was tested by David Wang - including using the pendant at the far end of the target hall where range was previously an issue. Everything is reported to be in working condition. Remote mode is functioning as expected.

The crane pendant for the auxiliary hoist was upgraded to a FLEX EX2 style pendant by Canco Cranes. The installation work was performed by Canco, supervised by Tom Kauss and David Wang. Installation work was performed in one day (I2021-03-26-1).

Items installed include: new pendant (2 motion, 2 speed)

The existing antenna and receiver box located in the Target Hall were used.

The new system was tested by David Wang. Everything is reported to be in working condition.

An annual electrical and mechanical inspection was performed on the SMP today by Adam Newsome, Dan McDonald, and Jason Zhang as per Work Permit I2021-07-07-3. 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 shards of plastic in the cable tray - they were removed and disposed of
• Check inside control panel: components and wiring, labeling
  • Labeling intact, components in good condition
  • One COM wire for the relay array was loose - it was tightened
• Verify camera views
  • This was not inspected but has recently been 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
  • Done
• Inspect tensioners
  • Done - OK
• Tighten fasteners
  • Done - OK
  • Note: some concern over socket head screws in slotted parts - they should have washers. Not a critical issue but worth checking into.
• Visual inspection
  • All OK

Overall the inspection was successful.

The emergency close mechanism for the Storage Vault door was tested by Adam Newsome and Travis Cave. The door was opened to its fully open limit, then closed with the emergency system.

The test was successful.

TM4 was moved from the conditioning station to the East target station.

The West Entrance Module has been moved to the South Hot Cell for repair.

A cable track was installed between the mini-storage vault and the silos, for the purpose of implementing a retractable cable chain (e-chain). This will allow for cables to be managed during door opening/closing, so that remote control operation of the door will be possible in the future. See Work Permit I2021-08-11-2 (Aug 11)

Holes were drilled into the motor mounting plate (IRH2089) to allow for mounting a limit switch on the plate. See Work Permit I2021-08-17-7 (Aug 17)

Preliminary testing was completed in which the e-chain was fixed to the door with a C-clamp. Local and remote functionality were checked, and limit switch functionality was verified. Everything is working as expected. A final test will be conducted once the e-chain is fixed to the door and cabling routed through it. See Work Permit I2021-08-19-1 (Aug 19)

The e-chain has not yet been fixed to the vault door - holes will be drilled in-situ after preliminary testing is complete to confirm positioning.

 Edit [2021-09-23]: the installation is complete and has been tested.

The West Entrance Module has been moved from the South Hot Cell to the West Target Station.

Remote capability was added for the mini-storage door control. The control signals originate from the Opto 22 Module box that is used for the SMP remote control (this is located just above the storage vault).
The controls signal assignment document has been updated and can be found in C:\PDM Vault\PDM_Vault\_models\isac\isac1\wpn-3919 - safe module parking\Electrical

In order to operate remotely:
- Plug the mini-storage control box power cable into a wall outlet (adjacent main storage vault, under stairs)
- Plug the motor output cable into the mini-storage door motor
- Unplug the local pendant from the box
- Plug the cable that comes from the remote module box into the connector that the pendant was plugged into (M12, 5 pole Murr connector)
- Using the remote control program from the ISAC RH control room, click on the Mini-Storage option and then click buttons for open and close to operate the door (note: it is important to verify both opening and closing functions work before attempting any remote operation).

Remote and local functionality have been tested and verified working.

It is recommended to mount the mini-storage control box in a convenient area near the mini-storage (possibly on the wall adjacent the main storage vault).

Please contact me if you have any further questions.

TM#2 was moved from ITW to SHC, then moved back to ITW.

It was noted on Nov. 9 that a squeaking noise was present when the turntable was rotated CCW with a module present.

Upon inspection, it appears the issue could be due to drive chain misalignment and improper tension. Furthermore, it was noted that a shaft collar on one of the existing chain tensioners was broken (a replacement was ordered).

Repairs will be performed on Nov. 19 to resolve these issues by re-aligning the chain, and resetting the tensioners. The turntable will be tested. This e-log will be updated once the work is complete and the system is returned to a functioning state. See Work Permit I2021-11-09--3

Edit, Nov. 19: the aforementioned repairs were completed and the turntable has been tested and is operating correctly. No squeaking noise is present. It is suggested to increase the diameter of the two chain tensioner shafts (and thus modify related bearing and shaft collar components) in order to prevent bending of the shaft which was observed. This will be done in the near future.
