|
Carla did the test. That is what she wrote in Feb 04th: "I am done with the HV testing at ITE - the results were the same as at ITW. It stayed at 59kV for 30 mins with no issues. Trying to go above 59.5kV is probably possible but a bit more risky. ITE also has a band, from 54-56kV, where the current jumps around like crazy". |

Thursday, February 17, 2022, 13:24, David Wang, Spent Target Vault, Maintenance, , UCx #34, Repackage of UCx #34in NHC.
|
UCX34# in pail 258(Vault lot 7C) has been repacked today. It is an investigation to find a possible leak source of radioactive Iodine in vault. The new pail number is 268. It is back to vault 7c . I wrote down the information in log book. The job is smooth today. I retrieved UCx 34 old pail and liner to TH. The liner from UCx#34 only has 3000 counts. I bagged it. It could be used later. However, the pail has 500K counts contamination on bottom outside rim. It may accidently be slided out of plastic bag and touched the NHC table during the repackage. I bagged it and store it in silo area. When we do drum clean up, I will throw it in the drum. |

Friday, February 25, 2022, 10:22, Adam Newsome, South Hot-Cell, Development, , , Addition of E-Stops and Turntable Vertical Motion Limit Switch
|
Two changes have been made to the control system to the South Hot Cell:
- Addition of two emergency stop buttons: one located in the Target Hall on the wall adjacent to the hot cell, and one located on the control panel adjacent the operator station.
- Addition of limit switches to the turntable's vertical drive system to prevent over-travel at both the upper and lower limits.
The emergency stops will both stop all turntable motion: vertical and rotational.
An update to operating procedures: in order for the vertical motion system to function, the limit switch cable must be plugged in. When plugging in the vertical drive motor to the wall outlet as per normal operating procedure, it is now required to also connect the limit switch (which is mounted near the motor on the driveshaft) to the cable coming from the appropriately labelled junction box on the South wall (M12 connector).
These changes are based on electrical drawings IRH2083 - IRH2085 and mechanical assembly drawing ITA6739. The changes have been commissioned according to commissioning plan Document-218490. The commissioning report will be uploaded to DocuShare. The work permit for this upgrade was I2022-02-15--3.

Replaced 9 old turbo pumps from ITE/ ITW and one 2A3M20 wire scanner from ITE are transferred to cyclotron tunnel for storage. It is TH RAD waste cleanup task in winter shut down. |
Monday, April 04, 2022, 10:44, Nadia Jorgenson, South Hot-Cell, Repair, , , Turntable Chain Repair
|
Last week we repaired the South Hot Cell turntable chain/sprocket. Chain was loose and there was a few section where the chain was not lining up properly with the sprockets.
3 issues were discovered:
- One of the pins was bent. It’s been replaced but is a temporary fix. Need to replace them with stronger pins.
- The smaller sprockets near the motor were too far from the main turntable sprocket which was causing the links to not immediately line up with the teeth on the turntable sprocket. With too much slack in the chain, it’s likely that this is were the misalignment was starting. This was fixed by adjusting the motor position and the position of the yellow plate bolted to the floor.
- The yellow plate that is bolted into the floor has oversized holes relative to the bolts/washers used. This allows us to adjust the position, but the washers are to thin and are being bent/pulled into the holes. Should be replaced with thicker washers that can withstand the tension and this will help prevent the plate from sliding out of position. |
Friday, May 06, 2022, 10:12, Adam Newsome, Spent Target Vault, Maintenance, , , Annual Inspection of Mini-Storage Vault
|
The annual inspection of the mini-storage vault was performed today. 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 (some loose, but were tightened)
Everything appears to be in good working order.
Note: in the near future, the bearings should be greased. This is planned to take place during the next inspection of the main storage vault. |
Wednesday, May 11, 2022, 16:15, Nadia Jorgenson, Spent Target Vault, Standard Operation, , , Emergency Close Mechanism Test
|
The emergency close mechanism for the Storage Vault door was tested by Travis Cave, Nadia Jorgenson, and Dan McDonald. The door was opened to its fully open limit, then closed with the emergency system.
The test was successful. |
Wednesday, May 11, 2022, 16:29, Nadia Jorgenson, Spent Target Vault, Standard Operation, , , Routine mechanical inspection: storage vault
|
An inspection was performed on drive systems for the main storage vault by Dan McDonald, Travis Cave and Nadia Jorgenson. The functionality was not tested. Some areas for improvement noted, but otherwise nothing concerning was discovered.
Notes:
-
The wire insulation to the motor is showing wear and tear. Should be replaced in the future. For now was patched with electrical tape, see picture. May be beneficial to add an e-chain for the portion of the wiring that moves when door is opening and closing
-
Emergency close mechanism cable should be changed to have a 5/32” Nico Sleeve
-
Moving parts still need to be lubricated
-
Chain inspected (OK)
-
Gearbox inspected - OK
-
All drive system set screws checked and tightened
-
Sprocket alignment checked - OK
-
Limit switches checked - OK
-
Emergency close mechanism cable checked - OK

Wednesday, May 25, 2022, 10:23, Nadia Jorgenson, Spent Target Vault, Repair, , , F-308 Loading, Mini-Storage Vault Failure
|
5 pails were moved from the mini-storage vault into F-308's
At one point during the loading the mini-storage vault door would not close. Cause was a blown fuse, which was replaced and operations were able to continue as usual. Possible reason the fuse blow was a tilted pail that may have become jammed between the tray and the roof of the mini-storage vault.
[Edit 2022-12-01, Adam Newsome]: the pails which were removed were: 220, 227, 233, 235, 238 |

|
An annual mechanical inspection was performed on the SMP today by Dan McDonald and Nadia Jorgenson. The following items were checked:
- Lubricate chains
- Inspect tensioners
- Tighten fasteners
- A few slightly loose, most are in need of washers, see attached pictures
- Could use some shims in a few places, see attached picture
- Inspect components during rotation - chain drive, rotary limit switch, and cable reel etc.

Monday, July 04, 2022, 11:54, Nadia Jorgenson, Spent Target Vault, Maintenance, , , Added Lubrication,fittings need to be changed
|
Dan lubricated components on the target storage vault (This was an outstand task from annual inspection). No issues on the main storage vault but we were not able to lubricate the mini storage vault because the position of the grease nipple on the fittings makes them inaccessible, see attached pictures. All four should be replaced with 90 deg fittings. |
