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.
13/160
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.

Required per UG-45 is the larger of tr1 or tr6 = 6.22 mm
Available nozzle wall thickness new, tn = 0.875*10.97 = 9.6 mm

Ae = Heff*ts + tp*Wp= 21.1667*1.3 + 1.3*42.5= 82.7667 cm2
S6 = K8*Q / Ae= 0.2035*53,783.45 / 8,276.6659= 1.322 MPa
Stress in saddle is acceptable (<= 0.9*Sy = 235.801 MPa)
Shear stress in anchor bolting, one end slotted
Maximum seismic or wind base shear = 0 N
Thermal expansion base shear = W*µ = 26,213.37 * 0.45= 11,796.02 N
Corroded root area for a 24 mm bolt = 3.3826 cm2 ( 4 per saddle )
Bolt shear stress = 11,796.02/(338.2574*4) = 8.718 MPa
Anchor bolt stress is acceptable (<= 103.421 MPa)
Web plate buckling check (Escoe pg 251)
Allowable compressive stress Sc is the lesser of 137.895 or 309.149 MPa: (137.895)
Sc = Ki*π2*E/(12*(1 - 0.32)*(di/tw)2)= 1.28*π2*19.99E+04/(12*(1 - 0.32)*(355.6/13)2)= 309.149 MPa
159/160
Allowable compressive load on the saddle
be = di*ts/(di*ts + 2*tw*(b - 1))= 14*0.5118/(14*0.5118 + 2*0.25*(13.7795 - 1))= 0.5286
Fb = n*(As + 2*be*tw)*Sc= 4*(2,139.95 + 2*13.43*13)*137.895= 1,372,908.05 N
Saddle loading of 56,060.94 N is <= Fb; satisfactory.
Primary bending + axial stress in the saddle due to end loads (assumes one saddle slotted)σb = V * (Hs - xo)* y / I + Q / A= 0 * (1,250 - 525.14)* 175 / (1e4*9,084.73) + 23,935.88 / 22,857.88= 1.047 MPa
The primary bending + axial stress in the saddle <= 137.895 MPa; satisfactory.
Secondary bending + axial stress in the saddle due to end loads (includes thermal expansion, assumes onesaddle slotted)σb = V * (Hs - xo)* y / I + Q / A= 11,796.02 * (1,250 - 525.14)* 175 / (1e4*9,084.73) + 23,935.88 / 22,857.88= 17.518 MPa
The secondary bending + axial stress in the saddle < 2*Sy= 524.002 MPa; satisfactory.
Saddle base plate thickness check (Roark sixth edition, Table 26, case 7a)
where a = 355.6, b = 168.5 mm
tb = (β1*q*b2/(1.5*Sa))0.5
= (1.8753*0.16*168.52/(1.5*137.895))0.5
= 6.42 mm
The base plate thickness of 16 mm is adequate.
Foundation bearing check
Sf = Qmax / (F*E)= 56,060.94 / (350*1,000)= 0.16 MPa
Concrete bearing stress < 11.432 MPa ; satisfactory.
