sis procedures described in ACI 349, with additional guidance provided RG 1.142. The design and analysis of anchors (steel embedments) used for component and structural supports on concrete structures are acceptable if found to be in accordance with ACI 349, Appendix B, with additional guidance provided by RG 1.199. Similar to the primary shield wall, the secondary shield walls are also subject to dynamic LOCA loads and the methods described in Subsection II.4.A.i are, therefore, applicable and acceptable. iii. Other Interior Structures Most of the other interior structures that are reviewed are combinations of reinforced concrete slabs, walls, beams, and columns, and steel beams and columns, which are classified as seismic Category I structures subject to the loads and load combinations described in Subsection II.3 of this SRP section. Analytical techniques for these structures are acceptable if found to be in accordance with those described in ACI 349, and with additional guidance provided by RG 1.142 and 1.199 for concrete and anchors (steel embedments,) respectively, and with ANSI/AISC N690-1994 including Supplement 2 (2004) for steel. 3.8.3-22 Revision 4 – September 2013 B. PWR Ice-Condenser Containment Internal Structures i. Divider Barrier The most important loads that usually govern the design of the divider barrier are those induced by a LOCA, including the differential pressure across the barrier and any concentrated jet impingement loads. Because the structural integrity of the divider barrier and, to a certain extent, its leak tight 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 design and analysis procedures of Article CC-3000 of the ASME Code, Section III, Division 2, apply, with additional guidance provided by applicable portions of SRP
