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
