Handover from TPO and inspection
- Completed
- Some modification to the center Inner-Outer conductor had to be made (hole enlarged as tab was slightly short)
Target Insertion:
Target Mounting:
- Upon fully seating UC#47 on service tray locating pins, the gas line VCR gasket came off
- Operator doesn't have line-of-sight to this area, so there has to be healthy clearance (Foreshadowing)
- Gas line VCR gasket reinstalled using manipulators
- 2nd seating of UC#47 on service tray locating pins, the gas line VCR gasket came off again
- Some alignment interference with the gas line coupling is the cause of the gasket falling off during placement (photo attached)
- Gas line on service tray was loosened, raised to highest position and fastened (Photo attached)
- Failed to re-install VCR gasket (Plastic separated from gasket material)
- Target removed from Hot cell to reinstall gaskets and make modifications to the gas-line coupling
- Gas line coil plastically deformed to give less of a spring action so the coupling can stay down under friction until it is time to couple
- Target carefully inserted into hot cell without disturbing spring/friction of gas-line coupling.
- This had to be repeated several times. Once for the waterline gaskets coming off, and a few other times to insert the target/tray without disturbing sprung coupling
- Target mounted without issue after the above steps successfully
Gas and Water Services:
- VCR connections coupled
- Leak test passed
- leak test faster today because module had been left in silo for a long time to dry out.
- Gas line no-longer needed, so was not checked
Electrical Services:
- Conductor bolts installed
- All bolts (including mounting bolts) checked for fit with mirror
- Coil conductor bolts torqued to at least 130inch-lbs
- Electrical test completed
Containment box panel reinstalled
Cleared area around module for craning out.
