isions 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. 3.8.3-22 Revision 2 - March 2007 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. 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 drywell 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 SRP Section 3.8.2, Subsection II.4. ii. Weir Wall One of the major loads to which the weir wall may be subjected is a jet impingement load induced by a pipe rupture in a nearby recirculation loop. The deflection of the wall under such a load must be limited so as not to impair the pressure-suppression performance. The procedures used to analyze the wall for such a dynamic time-dependent load are acceptable if a detailed time-history dynamic analysis is performed or if an equivalent static analysis is performed using the peak of the jet load amplified by an appropriately chosen dynamic load factor. The design and analysis procedures for concrete weir walls are
