Content:
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. 3.4. The applicant has met the requirements of GDC 4 by assuringensuring that the 74 design of steel containment is capable of withstanding the dynamic effects associated with missiles, pipe whipping, and discharging fluids. 4.5. The applicant has met the requirements of GDC 16 by designing the steel containment so that it is an essentially leaktight barrier to prevent the uncontrolled release of radioactive effluents to the environment. 5.6. The applicant has met the requirements of GDC 50 by designing the steel containment to accommodate, with sufficient margin, the design leakage rate, calculated pressure, and temperature conditions resulting from accident conditions and by assuringensuring that the design conditions are not exceeded 75 during the full course of the accident condition. In meeting these design requirements, the applicant has used the recommendations of regulatory guides and industry standards indicated below. The applicant has also performed appropriate analysis which demonstrates that the ultimate capacity of the containment will not be exceeded and establishes the minimum margin of safety for the design. The criteria used in the analysis, design, and construction of the steel containment structure to account for anticipated loadings and postulated conditions that may be imposed upon the structure during its service lifetime are in conformance with established criteria, codes, standards, and guides acceptable to the Regulatory staff. These include meeting the position of Regulatory Guide 1.57 and industry standard ASME Boiler and Pressure Vessel Code, Section III, Division 1, Subsection NE. The use of these criteria as defined by applicable codes, standards, and guides; the loads and loading combinations; the design and analysis
