and with those in the AISC specifications for steel. b. For 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 the loss-of-coolant acci- dent, including the differential pressure across the barrier and any concentrated Set impingement loads. As the divider barrier is a combination of walls and slabs framed together, the design and analysis procedures are acceptable if in accor- dance 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) Ice-condenser Elements The design and analysis procedures for the ice-condenser and its various components are acceptable if in accordance with either the elastic/linear design method of Part 1 of the AISC 3.8.3-22 Rev. 1 - July 1981 Specifications or with the plastic design method of Part 2 of the same Specifications. For componeints where experimental testing is utilized to verify the design, the testing proced- ures are acceptable if in accordance with recognized protoype or model testing procedures where the effect of scaling and similitude are taken into consideration. c. For BWR Containment Internal Structures (i) Drywell The design and analysis procedures utilized for concrete portions of the drywell are acceptable if in accordance with subsection II.4 of Standard Review Plan Section 3.8.1. For steel portions of the drywell that resist pressure but are not backed by structural concrete, the design and analysis proced- ures are acceptable if found in accordance with the applicable provisions of Subsection NE of
