- CHL:
# Replacement/upgrade of LN2 fill station gauging: -Materials: On-site -Pressure System: Standard Maintenance -Drawings: N/A -Fabrication: N/A -Operations: Working. Tank 2 complete. -Testing: Snoop upon installation.
# CHL Guard Vacuum -Materials: Ordered, expected on-site week of // 1/23 -Pressure System: Signed -Drawings: Complete -Fabrication: N/A -Operations: N/A -Testing: To be initial service leak checked upon completion of electrical work. Pump temperatures will also need to be monitored.
# LN2 Dewar #1 instrumentation tubing replacement -Materials: Ordered -Pressure System: Back in DA review -Drawings: Complete -Fabrication: pending material/dpf -Operations: N/A -Testing: To be initial service leak checked upon completion.
# LN2 PBC leaks -Materials: TBD -Pressure System: TBD -Drawings: TBD -Fabrication: TBD -Operations: All leaks have been identified and need to be tabulated and planned for repair/replacement. -Testing: TBD
# CHL Recovery Purifier Sieve replacement -Materials: on-site -Pressure System: N/A -Drawings: N/A -Fabrication: N/A -Operations: P5 sieve replaced and being cleaned. -Testing: N/A
# ESR ORS Carbon Replacement -Materials: Need to be identified and ordered. -Pressure System: N/A -Drawings: Need to be developed. -Fabrication: awaiting drawings -Operations: Needs to be scheduled/planned. -Testing: Snoop at joints. Spool pieces will need to be tested.

# ESR Oil collection -Materials: TBD -Pressure System: TBD -Drawings: TBD -Fabrication: TBD -Operations: May require piping removal or plant shutdown -Testing: not likely. category D piping at most.
ESR Status
-Halls A and C are cold and on cold return. -Hall C has been performing heat leak testing of the SHMS Q2. Expected to carry into week of 1/22. -Hall B is cooling solenoid. Expected to be on cold return 1/20/2017. -Hall C target system is being cleaned. Not connected to ESR or recovery as of now. -CHL-ESR x-fer line will be in use occasionally over the next week.
