nts of GDC 5 by demonstrating that SSCs are not shared between units or that sharing will not impair their ability to perform their intended safety functions. 5. The applicant has met the requirements of GDC 50 by designing the containment internal structures to accommodate, with sufficient margin, the design leakage rate, calculated pressure, and temperature conditions resulting from accident conditions and 3.8.3-34 Revision 2 - March 2007 by ensuring that the design conditions are not exceeded during the full course of the accident condition. In meeting these design requirements, the applicant has used the recommendations of the regulatory guides and industry standards indicated below. The applicant has also performed appropriate analysis to demonstrate that the ultimate capacity of the structures will not be exceeded and to establish the minimum margin of safety for the design. 6. The applicant has met the requirements of 10 CFR 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 RG 1.57, 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 RG 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
