Content:
ments of 10 CFR Part 50, Appendix B by providing a quality assurance program that includes adequate measures for implementing guidelines relating to structural design. The criteria used in the design, analysis, and construction of the containment internal structures to account for anticipated loadings and postulated conditions that may be imposed upon each structure during its service lifetime conform to established criteria, codes, standards, and specifications acceptable to the NRC staff. This includes meeting the positions of RGs 1.57, 3.8.3-36 Draft Revision 4 - December 2012 1.69, 1.136, 1.142, 1.143, 1.160, and 1.199, as well as industry codes and standards ACI-349; ANSI/AISC N690-1994 including Supplement 2 (2004,) and, depending on the structure, ASME Code, Section III, Division 1, Subsection NE, or ASME Code, Section III, Division 2, Subsection CC, with additional guidance provided by RGs 1.57 and 1.136, respectively. The use of these criteria, as defined by the applicable codes, standards, and specifications; loads and loading combinations; design and analysis procedures; structural acceptance criteria; materials, quality control programs, and special construction techniques; and testing and inservice surveillance requirements, provides reasonable assurance that, in the event of earthquakes and various postulated accidents occurring within the containment, the containment internal structures will withstand the specified design conditions without impairment of structural integrity or the performance of required safety functions. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable.
