Subject: SNSPPU Helium vessel welding traveler

Valerie and Megan,

I see we have several drop downs for helium vessel serial numbers in the SNSPPU Helium vessel weld traveler.  I'm not well plugged into the understanding for each of these serial numbers abbreviations.  We're going to need to have a description by each one of these.   Can you help?

HELVSN - HELium vessel assembly
HLSSN - He Level Sensor
HEHDFSN - HE vessel HeaD Fpc end
HEHDPSN - HE vessel HeaD Probe end
HESSN - HE vessel Shell (Cylinder)

In addition I would like to fill this traveler out for the first prototype weldment of HB-046.
We used old leftover parts from the first SNS project to weld onto the cavity for testing.  These parts don't have serial numbers.  What should I select for the three prototype vessels.  Should we add prototype1, 2, 3 as serial numbers?

The serial numbers for the prototypes may be prefixed with "P" followed by a single digit serial number.

We can talk about this on Friday at the C75 meeting if we need to.

Thanks for your input.  Not sure how we should handle this?
Kurt
