Notes:(1) F&D 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 F&D Head #2 and F&D Head #1.

The test temperature of 70 °F is warmer than the minimum recommended temperature of -3.9 °F so the brittlefracture provision of UG-99(h) has been met.

UW-16(c) Weld Check

Fillet weld: tmin = lesser of 0.75 or tn or t = 0.219 in

tc(min) = lesser of 0.25 or 0.7*tmin = 0.1533 in

tc(actual) = 0.7*Leg = 0.7*0.5 = 0.35 in

The fillet weld size is satisfactory.

Weld strength calculations are not required for this detail which conforms to Fig. UW-16.1, sketch (c-e).
