Shop test pressure determination for Chamber bounded by F&D Head #2 and F&D Head #1

based on MAWP per UG-99(b)

Notes:

(1) F&D Head #1 limits the UG-99(b) stress ratio.

(2) The zero degree angular position is assumed to be up, and the test liquid height is assumed to the

top-most flange.

The field test condition has not been investigated for the Chamber bounded by F&D Head #2 and

F&D Head #1.

The test temperature of 28 °C is warmer than the minimum recommended temperature of -14.5 °C so

the brittle fracture provision of UG-99(h) has been met.
