The following tasks were performed:
- All electrical, water, and pneumatic connections to the T1 target was reconnected.
- 3x and 2x CUNO filters for T1 and T2 respectively were changed (O-ring for the housings were not changed).
- All hansen fittings on the front mounting plates of the T1 and T2 cooling packages were inspected.
- All proteus paddle wheels (Q1-5) for both T1 and T2 were replaced.
- The main reservoir drain valves on both cooling packages were closed in preparation for re-filling.
- All other ball valves in the cooling packages were returned to open, also in preparation for re-filling.
Two buckets containing (primarily) active water from the CUNO filters were brought closer to the boot up area, to be moved to the active sink in the MH hot cell lab in the coming days (pending ELOG update).
Spent shafts, paddle wheels, and o-rings from the proteus flow meters will be checked and appropriately tagged/disposed of, also in the coming days.
------------------------------------------------
Some observations for future shutdown work:
- The drain port at the bottom of the CUNO filter housings can be used to verify that the filter line has been successfully closed off.
- Prepare several lengths of flathead screws to service the proteus flowmeters.
- Prepare spare locknuts and screws for the proteus flowmeters in case they become stripped or a locknut is dropped.
- Stick to well-fitting gloves to make using screwdrivers, picking screws, etc. easier.
- Possibly a pipe or coupling could be used with the tool for the CUNO filters to make it easier to loosen the CUNO filter nut in hard to reach areas.
- If possible, it may be a good idea to replace the o-rings on the CUNO filter housings in future shutdown operations (dash # to be identified).
