Spent target UCx #33 has been repacked with a new pail and lid in NHC. Old pail #255. New pail # 267. Location: Vault slot 1C.  it is an investigation job for  a possible leak pail in vault.  

  2307   Thursday, February 17, 2022, 13:24 David WangSpent Target VaultMaintenance UCx #34Repackage 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.

UCx 32# P2N target in vault slot 1B is repacked is morning for Ferran to take out his samples( in two small plastic containers) stored in pail last July when Chad did the spent target job. The job went well.  Old pail # is 254# and new pail # is 233. It is put back to 1B in vault.

  2318   Friday, May 06, 2022, 10:12 Adam NewsomeSpent Target VaultMaintenance  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.

  2319   Wednesday, May 11, 2022, 16:15 Nadia JorgensonSpent Target VaultStandard 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.

  2320   Wednesday, May 11, 2022, 16:29 Nadia JorgensonSpent Target VaultStandard 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

  2324   Wednesday, May 25, 2022, 10:23 Nadia JorgensonSpent Target VaultRepair  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

  2344   Monday, July 04, 2022, 11:54 Nadia JorgensonSpent Target VaultMaintenance  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.

  2366   Wednesday, September 14, 2022, 13:45 Adam NewsomeSpent Target VaultDevelopment  Storage Vault: cable replaced and e-chain upgrade

The motor cable for the storage vault was replaced as the old one was showing signs of wear. The U-track that the old cable ran through was also bent as a result of being hit.

In the process of replacing the cable, an e-chain was installed for cable management purposes. Mounting brackets were modified and a new U-track was installed as well. The new hardware is more robust than what was previously installed.

The vault door was opened and closed multiple times while observing the e-chain - everything behaved as expected. The system is operational.

 

Solidworks model IRH0189 is updated to show the changes
