Notes:(1) F&D Head #1 limits the UG-99 stress ratio.
(2) PL stresses at nozzle openings have been estimated using the method described in PVP-Vol. 399, pages 77-82.(3) VIII-2, AD-151.1(b) used as the basis for nozzle allowable test stress.(4) 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 70 °F is warmer than the minimum recommended temperature of -3.9 °F so the brittlefracture provision of UG-99(h) has been met.
