A safety walkaround for July 2024 was completed by A. Kong.

Results can be found in the master spreadsheet

Major deficiencies:

• Identified a 1/2 ton chain hoist missing an inspection tag. Mechanical Services will need to be informed about this.

During a replacement of the RCR1 active sump (mechanical services group), approximately 600L of non-active grey water was released into the RH active sump. At this time, this should be all of the water in the RH sump (approximately 600L total).

A safety walkaround was completed for the Meson Hall Hot/Warm Cells.

The resulting spreadsheet can be found on DocuShare as Document-242733.

Main deficiencies identified:

• Hot Cells:
  • Pressure gauge reading is suspect
  • Operator station phone not working (resolved now)
• General:
  • Lifting equipment has overdue inspection

Action has been taken on all deficiencies.

The following maintenance tasks were completed on 2024-11-29 by A. Newsome, A. Kong, A. Tam, M. Dalla Valle:

• Warm cell right window water level topup... the water level was a couple inches lower from the top. Using a tube connected to the nearby sink, the level was topped up fully. See attached before/after picture.
• Hot cell oil level checks:
  • Right side OK. See attached picture.
  • Left side very low compared to July 2022 measurement (suspect internal leak?). The oil was topped up. See attached before/after picture.
• Hot cell scissor table pump oil level check - M. Dalla Valle notes this was topped up approximately July 2022. The table was operated and functioned normally, did not sound concerning. The oil level was visible and acceptable.

Still to do, next maintenance check-up:

• Check HC atmospheric pressure differential gauge
• Lubricate HC turntable (planned for 2025 winter shutdown when target assembly not present)
• Lubricate all telemanipulators
