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 Section 3.8.1 and RG 1.136. For the other concrete portions of the divider barrier, the design and analysis procedures are acceptable if found to be in accordance with ACI 349, with additional guidance provided by RGs 1.142 and 1.199. These methods are based on linear elastic design methods unless the structure is subjected to concentrated accident loads, as discussed in Subsection II.4.A.i, in which elasto-plastic behavior may be assumed. For steel portions of the divider barrier that resist pressure but are not backed by structural concrete, the design and analysis procedures are acceptable if found to be in accordance with the applicable provisions of Subsection NE of the ASME Code, Section III, Division 1 apply, with additional guidance provided by applicable portions of SRP Section 3.8.2 and RG 1.57. ii. Ice-Condenser Elements The design and analysis procedures for the ice-condenser and its various components are acceptable if found to be in accordance with either the elastic/linear design method of Part 1 of ANSI/AISC N690-1994 including Supplement 2 (2004), or the plastic design method of Part 2 of the same specifications. For components using experimental testing to verify the design, the testing procedures are acceptable if found to be in accordance with recognized prototype or model testing procedures that consider the effect of scaling and similitude. C. BWR Containment Internal Structures This SRP section is oriented toward the BWR Mark III containment concept. Other BWR containment types are reviewed in a similar manner. 3.8.3-23 Revision 4 – September 2013 i. Drywell The design and analysis procedures used for concrete portions of the drywell are acceptable if found to be in accordance with Subsection II.4 of SRP Section 3.8.1. For steel portions of the
