Content:
For earth retaining walls that are not restrained by a building, the guidance in ASCE 4-98 Sections 3.5.3.1 through 3.5.3.3 is acceptable. I. The design of masonry walls is considered acceptable when it meets the requirements of Appendix A of this SRP. J. The design of structures that use modular construction methods are reviewed and evaluated on a case-by-case basis. NUREG/CR-6486 provides guidance related to the use of modular construction methods. Appendix B to NUREG/CR-6486 includes proposed modular construction review criteria. 5. Structural Acceptance Criteria. For each of the loading combinations delineated in Subsection II.3 of this SRP section, the structural acceptance criteria appear in ACI 349 and RG 1.142 for concrete structures, and AISC N690-1994, including Supplement 2 (2004), for steel structures. The structural acceptance criteria for structures that use modular construction methods are evaluated on a case-by-case basis. See Subsection II.4.J of this SRP for information. 6. Materials, Quality Control, and Special Construction Techniques. For Seismic Category I structures outside the containment, the materials and quality control programs are acceptable if found in accordance with the codes and standards indicated in Subsection I.6 of this SRP section. Special construction techniques, if any, are evaluated on a case-by-case basis. For modular construction, reviewers evaluate the materials, quality control, and special construction techniques on a case-by-case basis. See Subsection II.4.J of this SRP section for more information. 3.8.4-13 Draft Revision 4 – December 2012 7. Testing and Inservice Surveillance Requirements. For Seismic Category I structures outside containment, structures monitoring and maintenance requirements are acceptable if program is in accordance with 10 CFR 50.65 and RG 1.160. For water control structures, inservice inspection programs are acceptable if in accordance with RG 1.127. Water control structures covered by this
