Hydrostatic Test
Shop test pressure determination for Chamber bounded by Welded Cover #1 and Top of vessel based onMAWP per UG-99(b)
Shop hydrostatic test gauge pressure is 30.04 kg/cm2 at 21.11 °C (the chamber MAWP = 23.11 kg/cm2)
The shop test is performed with the vessel in the horizontal position.

Notes:(1) Cylinder #1 limits the UG-99 stress ratio.(2) NI indicates that test stress was not investigated.(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 Welded Cover #1 and Top of vessel.
The test temperature of 21.11 °C is warmer than the minimum recommended temperature of -12 °C so the brittlefracture provision of UG-99(h) has been met.
