to this SRP section,10 including the following areas: a. General assumptions on boundary conditions. b. The expected behavior under loads and the methods by which vertical and lateral loads and forces are transmitted from the various elements to their supports and eventually to the foundation of the structure. c. The computer programs that are utilized. d. A design report on Category I structures is reviewed (Appendix C). e. A structural audit is performed (Appendix B). f. The design of the spent fuel pool and racks is reviewed (Appendix D). g. Steel embedments are reviewed (Appendix E).11 h. Steel-related structures are evaluated on the basis of ANSI/AISC N690-1984 (Appendix F).12 i. Dynamic soil pressures on earth retaining walls and embedded walls are reviewed for nuclear power plant structures (Appendix G).13 5. Structural Acceptance Criteria The design limits imposed on the various parameters that serve to quantify the structural behavior of each structure and its components are reviewed, specifically with respect to stresses, strains, gross deformations, and factors of safety against structural failure. For each load combination specified, the specified allowable limits are compared with the 14 acceptable limits delineated in subsSection II.5 of this SRP sectionplan.15 6. Materials, Quality Control, Special Construction Techniques, and Quality Assurance Information on the materials that are used in the construction of Category I structures is reviewed. Among the major materials of construction that are reviewed are the concrete ingredients, the reinforcing bars and splices, and the structural steel and anchors. The quality control parameters that are proposed for the fabrication and construction of Category I structures are reviewed, including nondestructive examination of the materials to determine physical properties, placement of concrete, and erection tolerances. Special construction techniques, if proposed, are reviewed on a case-by-case basis to
