    Notes:(1) P L stresses at nozzle openings have been estimated using the method described in PVP-Vol. 399, pages 77-82.(2) 1,5*0,9*S y used as the basis for the maximum local primary membrane stress at the nozzle intersection P L.(3) 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 BOTTOM HEAD and TOP HEAD.

    The test temperature of 50 F is warmer than the minimum recommended temperature of -15,1 F so the brittlefracture provision of UG-99(h) has been met.

    Fig UCS-66.2 general note (1) applies.

    Nozzle is impact test exempt to -155 F per UCS-66(b)(3) (coincident ratio = 0,0323).

    Nozzle rated MDMT: -155 FParallel Limit of reinforcement per UG-40

    LR = MAX(d, R n + (t n - C n) + (t - C))= MAX(1,937, 0,9685 + (0,344 - 0,125) + (0,3125 - 0,125))= 1,937 in

    Outer Normal Limit of reinforcement per UG-40

    LH = MIN(2,5*(t - C), 2,5*(t n - C n) + t e)= MIN(2,5*(0,3125 - 0,125), 2,5*(0,344 - 0,125) + 0)= 0,4688 in

    Required thickness t r from UG-37(a)

    tr = P*R / (S*E - 0,6*P)= 100*21,1875 / (20.000*1 - 0,6*100)= 0,1063 in

    This opening does not require reinforcement per UG-36(c)(3)(a)

    UW-16(c) Weld Check

    Fillet weld: t min = lesser of 0,75 or t n or t = 0,1875 intc(min) = lesser of 0,25 or 0,7*t min = 0,1312 intc(actual) = 0,7*Leg = 0.7*0,375 = 0,2625 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).
