Q. Entergy has previously claimed that using the bounding Fen values recommended in
NUREG/CR-6909 would actually yield less conservative CUFHQ values, because the ASME
Code design air curves for carbon steel and low-alloy steels contained in air [which is what
Entergy considered] . . . are more conservative than the newer air curves in NUREG/CR-
6909. 4 How would you respond to this assertion?
