PTW-12240 covers 3" knockouts in racks SL03B11, SL13B09.

There is a linked PTW to this ATLis, 12242 that covers CPS breaker handle replacement, although which exact zones is not specified. PTW also calls out PSS performing ZVV, which doesn't seem right.

Once exact PTW to be used is confirmed, and once planning is approved for it, please submit this ATLis with an estimated date for execution.

Thanks.

Tuesday:
Moved mirror puck to SM 1, puck 34 to SM 1 before removing magnets from manipulators
Verified heater working: 5A -> 1 V, 6A for 15-20 min got above 50C.
Checked RGA trace with heater on - no significant change, slight increase in pressures

Moved turbo cart from beam left at 1I01 to beam right with pinch off valve to clear space for laser box work

Closed valve between overboard IP and turbo cart - no significant change in RGA trace. Final bagged leak check of system before starting bake setup - found small leak in gauge on pump cart, this should not affect the bakeout.

Task approved. Will add SL11 drip pan work to Mon 11/9 - Wed 11/11.

Note that the tunnel will be ODH-2 from ~6AM - ~1PM Tu 11/10, and so no work should be planned in the tunnel during this period.

When moving on to other locations after SL11, please comment on this ATLis ahead of time. Unlikely there will be conflicts with other jobs, but not impossible.

PTW-95863 does not exist. Looked back at previous ATLiss for drip pan work, found PTW-9583 -- Leak Repair Accelerator Tunnel, on-issue up until 1/29/27. This seems like the right one. If not, please comment with the right one.

Linked previous ATLiss of related work.

Body: 

Discussed with F&O -- for those interested, yes, this is similar to the vibrations that were seen on the NAB Cooling Tower (B67) for the West Arc LCW system that eventually led to a pinhole leak in the cyclone separator.

To confirm, CHL Cooling Tower functionality will not be impacted when constructing these concrete pads, correct?

Please attach supporting documentation such as Dig/Excavation Permit and subcontractor AHA to this ATLis when you have it.
