of codes, standards, guides, and specifications is checked against the list in Subsection II.2 of this SRP section. The reviewer verifies the use of the appropriate code or guide and the acceptability of the applicable edition and stated effective addenda. 3. Loads and Loading Combinations. The reviewer verifies that the loads and load combinations are consistent with those specified in Subsection II.3 of this SRP section. Any deviations from the acceptance criteria for loads and load combinations are reviewed for adequate justification. 4. Design and Analysis Procedures. The reviewer becomes familiar with the design and analysis procedures that are generally used for the type of structures being reviewed. Because the assumptions regarding the expected behavior of the structure and its various elements under loads may be significant, the reviewer evaluates their acceptability based on the acceptance criteria provided in Section II. The design and analysis procedures, including the behavior of the structures under various loads and the manner in which these loads are treated in conjunction with other coexistent loads are reviewed to establish compliance with procedures delineated in Subsection II.4 of this SRP section. These include the criteria for computer programs, consideration of concrete cracking, design reports, and the structural audit. As discussed in Subsection II.4.E of this SRP section, the use of modular construction methods is reviewed on a case-by-case basis using guidance provided in NUREG/CR-6486. 5. Structural Acceptance Criteria. The limits on allowable stresses and strains in the structural elements, including concrete, reinforcement, structural steel, and anchors, are compared with those specified in Subsection II.5 of this SRP section. The reviewer evaluates the justification provided to demonstrate that the functional 3.8.3-34 Draft Revision 4 - December 2012 6. integrity of the structure will not be affected, when the applicant proposes to
