Hydrostatic Test

Shop test pressure determination for Chamber bounded by Ellipsoidal Head #2 and Ellipsoidal Head #1 based onMAWP per UG-99(b)

Shop hydrostatic test gauge pressure is 480.914 psi at 70.00 °F (the chamber MAWP = 369.934 psi)

The shop test is performed with the vessel in the horizontal position.

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-most flange.

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

The test temperature of 70.00 °F is warmer than the minimum recommended temperature of -8.30 °F so the brittle fracturprovision of UG-99(h) has been met.
