Wednesday, September 14, 2022, 13:45, Adam Newsome, Spent Target Vault, Development, , , 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 |

|
A modification was made to integrate the hot cell's lift table into the E-stop circuit. See work permit I2022-10-07-1
The E-stop mounted on the right side of the small enclosure adjacent to the operator station will now serve to stop the lift table's up and down
motion, as well as the turntables up/down and CW/CCW motions. Functionality was checked by B. Webster (electrical services) and A. Newsome. |

|
[edit 2023-01-03] The crane was powered back on this morning - there do not appear to be any faults and it seems that the crane was unaffected by the
power outage.
The ISAC target hall overhead crane was powered off for the holidays. Note that this may result in the commonly observed PLC battery failure issue |

|
The following three pails were moved from the main storage vault to the mini-storage vault:
1. #211, Ta#58 (formerly vault location 3C)
2. #217, ZrC#8 (formerly vault location 3A) |

Monday, March 06, 2023, 11:31, Adam Newsome, North Hot-Cell, Repair, , , Spare Telemanipulator: Y-Motion Linear Actuator Repair
|
The linear actuator used for the Y-motion motor assistance on the spare telemanipulator was replaced and tested. It was observed around September 2021
that the former one which was installed was causing fuses to blow for the main 120 VAC power supply in the control box. After some troubleshooting, it
was determined that the linear actuator itself did not operate smoothly - it was suspected that this caused motor overload due to additional friction. |

Tuesday, June 20, 2023, 12:37, Adam Newsome, Assembly/Bench Test, Development, , , Modifications to wire ropes for pails within existing F-308s 6x
|
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. |
