Ed & Naeem,

It's unclear to me if there is a consensus on how many breakdown 
travelers that PPU project wants to have for a certain assembly to be 
inspected. I hope that you can clarify what you want all SOTRs to prepare.

The usual receiving inspection steps that I can think of are:
shipping crate condition check --- this would be in INV
vendor documents check --- docs upload to INV. SOTR as well as SMEs need 
to check them for completeness and correctness
visual inspection --- SRF QC or CMA
dimensional inspection --- may be done by SRF QC folks or Survey & 
Alignment folks
instrumentation electrical check out --- Larry's group
fit-up test  --- mostly done CMA
weld inspection --- by weld examiner or CWI
cold shock  --- CMA
pressure test  --- CMA
leak check  --- CMA
repackage

Please advise. I am about to convert Ed's SNS end can travelers to the 
new format and need to know how many travelers that I need to write for 
Supply & Return End Cans.

Thanks,
Gary
