tructure to withstand the most severe earthquake that has been established for the site with sufficient margin and the combinations of the effects of normal and accident conditions with the effects of environmental loadings such as earthquakes and other natural phenomena. DRAFT Rev. 2 - April 1996 3.8.3-38 3. The applicant has met the requirements of GDC 4 by assuring that the design of the internal structures are capable of withstandingdesigning the containment internal structure to withstand the dynamic effects associated with missiles, pipe whipping, and 145 discharging fluids. 4. The applicant has met the requirements of GDC 5 by demonstrating that structures, systems, and components are not shared between units or that, if snared shared, they 146 have demonstrated that sharing will not impair their ability to perform their intended safety function. 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 by ensuringassuring 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 which demonstrates the ultimate capacity of the structures will not be exceeded and establishes the minimum margin of safety for the 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 during the structures during their service lifetime are in conformance with established criteria and with codes, standards, and specifications acceptable to the Regulatory staff. These include meeting the positions of Regulatory Guides 1.10,
