a combination of walls and slabs framed together, the design and analysis procedures are acceptable if found in accordance with the ACI 318 Code for the concrete portions of the divider barrier. These methods are based on the elastic/linear working stress design method where actual stresses are determined. 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 in accordance with the applicable provisions of Subsection NE of the ASME Code, Section III, Division 1. (ii)ii. Ice-condenser Elements The design and analysis procedures for the ice-condenser and its various components are acceptable if found in accordance with either the elastic/linear design method of Part 1 of the AISC N690 Specifications 108 or with the plastic design method of Part 2 of the same specifications. For components where experimental testing is utilized to verify the design, the testing procedures are acceptable if found in accordance with recognized prototype or model testing procedures where the effect of scaling and similitude are taken into consideration. c. For BWR Containment Internal Structures (i)i. Drywell The design and analysis procedures utilized for concrete portions of the drywell are acceptable if found in accordance with subsection II.4 of Standard Review PlanSRP 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 in accordance with the applicable provisions of Subsection NE of the ASME Code, Section III, Division 1. 3.8.3-27 DRAFT Rev. 2 - April 1996 (ii)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
