Don't know if it applies here, but Engineer's Edge has become a routine
stop for me as a free resource:

Thanks...I had seen it before but it didn't come up in my searches this
time. Looking, I found a pressure vessel calculator that gives somewhat
higher values at similar conditions but it has no references to the
basis for the computation, unfortunately, so I can't tell what's causing
them. Clearly it's not the same as B31.1 but doesn't reference either a
Standard nor the criterion behind it so can't tell.

Unfortunately, they don't have a link to the pertinent ASME Standard,
either...so, useful site for much but didn't help me out on this
particular sidelight trivia quest...it got me to wondering in that I
really don't know what the dimensions actually are, myself. I've got
the TVA design book for a couple of the older plants we did some
technology demonstration projects at but they're not of any help for the
supercritical units, unfortunately.
