ing criteria are acceptable if found in accordance with the following: d. Divider barrier As the structural integrity of the divider barrier and, to a certain extent, its leak-tight integrity as well, are important to the proper functioning of the ice-condenser containment system, it is treated for design purposes similar to the containment itself. Accordingly, for concrete pressure-resisting portions of the divider barrier, the loads and load combinations of Article CC-3000 of ASME Section III Division 2 Code (Ref. 4) will apply, with the following exceptions. For Table CC-3230-1 (i) In the third combination 0.5 under E should be replaced by the word "or." (ii) It should be indicated that the maximum values of P , T , Ra R , including an appropriate dynamic load factor, sfioulg be applied simultaneously, unless a time-history is performed to justify otherwise. Steel portions of the divider barrier which resist the design differential pressure and are not backed by concrete, such as pene- trations, hatches, locks and guard pipes, should be designed in accordance with the appropriate sections of Subsection NE of the ASME Code, Section III, Division 1, (Ref. 5), together with the applicable loads, load combinations, and acceptance criteria of Regulatory Guide 1.57 (Ref. 9). e. Ice-Condenser Elements In the ice-condenser containment system the structural integrity of the ice baskets, ice bed framing, and their supports, is important to the functional integrity of the containment system. The major loads that are applicable to the ice-condenser elements are: D, L, E, E', and P . For this structure, P is the LOCA pressure load induced by dPag and change in momentui of the flowing air and steam. Load combinations for the ice-condenser elements are acceptable if found in accordance with the following: (i) For service load conditions, if elastic working stress design methods are used: (1) D + L 3.8. 3-19 Rev. 1 - July 1981 (2) D + L + E (ii) For service load conditions, if
