Notes:(1) Ellipsoidal 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-mostflange.

The field test condition has not been investigated for the Chamber bounded by Ellipsoidal Head #2 and EllipsoidalHead #1.

The test temperature of 21.11 °C is warmer than the minimum recommended temperature of 6.25 °C so the brittlefracture provision of UG-99(h) has been met.
