tively. ii. Ice-Condenser Elements For load combination delineated in Subsection II.3 of this SRP section, the specified limits for stresses and strain are acceptable if found to be in accordance with those given in ANSI/AISC N690-1994 including Supplement 2 (2004). D. BWR Containment Drywell This SRP section is oriented toward the BWR Mark III containment concept. Other BWR containment types are reviewed in a similar manner. For concrete and steel portions of the drywell, the specified limits for stresses and strain are acceptable if found to be in accordance with the acceptance criteria of item II.5.C.i as described for the divider barrier. For the lower vent portion of the drywell, the following conditions apply: 3.8.3-26 Revision 2 - March 2007 i. If the main reinforcement of the drywell is carried down between the vent holes, and the reinforced concrete section is relied upon for structural purposes, the structural acceptance criteria are the same as for item II.5.C.i above for concrete. ii. If the main reinforcement of the drywell is terminated above the vent holes, and two steel plates lining both faces of the wall are used for structural purposes, the acceptance criteria are reviewed on a case-by- case basis. iii. If other structural systems are used in the vent region, the acceptance criteria are also reviewed on a case-by-case basis. 6. Materials, Quality Control, and Special Construction Techniques. The specified materials of construction and quality control programs are acceptable if found to be in accordance with the public code or standard as indicated in Subsection I.6 of this SRP section. Special construction techniques, if any, are treated on a case-by-case basis. For modular construction, the materials, quality control, and special construction techniques are also reviewed on a case-by-case basis. See Section II.4.E of this SRP section for further information. 7. Testing and Inservice Surveillance Requirements. BWR containment drywells, such as
