94 including Supplement 2 (2004). This specification uses the allowable stress design (ASD) method. Use of the load and resistance factor design (LRFD) version of the specification (N690L) is reviewed on a case-by-case basis. The supplemental criteria on the use of loads and load combinations presented above for concrete structures also apply to steel structures. 3.8.3-17 Revision 3 - May 2010 C. Divider Barrier and Ice-Condenser of the PWR Ice-Condenser Containment Specific load and load combination criteria applicable to the divider barrier and ice-condenser elements are given below. Supplemental criteria presented in Subsection II.3.A of this SRP section are also applicable. i. Divider Barrier Because the structural integrity of the divider barrier and, to a certain extent, its leaktight integrity are important to the proper functioning of the ice-condenser containment system, it is treated, for design purposes, in a manner 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 the ASME Code, Section III, Division 2, with additional guidance provided by applicable portions of SRP Section 3.8.1 and RG 1.136. For other concrete portions of the divider barrier, the loads and load combinations as defined in Subsection II.3.A apply. Steel portions of the divider barrier that resist the design differential pressure and are not backed by concrete, such as penetrations, 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, with additional criteria provided by applicable portions of SRP Section 3.8.2 and RG 1.57 apply. For other steel portions of the divider barrier, the loads and load combinations as defined in Subsection II.3.B apply. ii. Ice-Condenser Elements The structural integrity of the ice baskets, ice-bed framing, and their supports is important to the
