Hydrostatic Test

Shop test pressure determination for Chamber bounded by Bottom Head and Top Head based on MAWP per UG-99(b)

Shop hydrostatic test gauge pressure is 130.000 psi at 70.00 °F (the chamber MAWP = 100.000 psi)

Notes:(1) Top Head 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 Bottom Head and Top Head.

The test temperature of 70.00 °F is warmer than the minimum recommended temperature of -25.00 °F so the brittle fracture provision of UG-99(h) has been met.

= 0.5*(6 - 2)*Sqr(3*4.284222/36,000.00)= 0.0378 in

The base plate thickness is adequate.

Applied Loads

Radial load: Pr = 0.00 lbf

Circumferential moment: Mc = 0.00 lbf-in

Circumferential shear: Vc = 0.00 lbf

Longitudinal moment: ML = 101.57 lbf-in

Longitudinal shear: VL = 158.21 lbf

Torsion moment: Mt = 0.00 lbf-in

Internal pressure: P = 100.000 psi

Mean shell radius: Rm = 17.9063 in

Local shell thickness: t = 0.1875 in

Shell yield stress: Sy = 35,700.00 psi

Maximum stresses due to the applied loads at the leg edge (includes pressure)

Rm/t =95.5

C1 = 1.4142, C2 = 5.6568 in

Note: Actual lug C1/C2 < 1/4, C1/C2 = 1/4 used as this is the minimum ratio covered by WRC 107.

Local circumferential pressure stress = P*Ri/t = 9,500.00 psi

Local longitudinal pressure stress = P*Ri/2t = 4,750.00 psi

Maximum combined stress (PL+Pb+Q) = 9,648.00 psi


Legs

Allowable combined stress (PL+Pb+Q) = +-3*S = +-60,000.00 psi

The maximum combined stress (PL+Pb+Q) is within allowable limits.

Maximum local primary membrane stress (PL) = 9,532.00 psiAllowable local primary membrane (PL) = +-1.5*S = +-30,000.00 psi

The maximum local primary membrane stress (PL) is within allowable limits.
