    Notes:

    (1) F&D Head #1 limits the UG-99 stress ratio.(2) PLstresses at nozzle openings have been estimated using the method described in PVP-Vol. 399, pages 77-82.

    (3) 1.5*0.9*Syused as the basis for the maximum local primary membrane stress at the nozzle intersection PL.

    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 -23.9 F so the brittlefracture provision of UG-99(h) has been met.
