We believe if we have a nozzle > NPS 10" or > 1 1/8" thickness, we need to use the joint efficiency from UW-12 on the long weld seam of the nozzle in addition to the weld factor in the allowable stress from Section II.
The question is how does whether you spot x-ray the vessel section Category B or C joints affect the nozzle efficiency per UW-11 (a) (5) (b)?
Appendix L-9.2.4 seems to indicate this has a factor on when you "double dip" and take the weld efficiency in addtion to the welded stress value from Section II.
