below. 2. The applicant has met the requirements of GCD 2 by designing the seismic Category I foundation 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. 3. The applicant has met the requirements of GDC 4 by enassuring that thefoundations are designed as seismic Category I foundations and are capable of withstanding the 66 dynamic effects associated with missiles, pipe whipping, and discharging fluids. 4. The applicant has met the requirements of GDC 5 by demonstrating that structure systems and components either are not shared between units or that, if shared, they have demonstrated that sharing will not impair their ability to perform their intended safety function. The criteria used in the analysis, design, and construction of all the plant seismic Category I foundations to account for anticipated loadings and postulated conditions that may be imposed upon each foundation during its service lifetime are in conformance with established criteria, codes, standards, and specifications acceptable to the Regulatory staff. These include meeting the positions of Regulatory Guide 1.142 and industry standards ACI-349 and AISC N690, "Specification for Design, Fabrication and Erection of Structural Steel for Building.67 DRAFT Rev. 2 - April 1996 3.8.5-14 The use of these criteria as defined by applicable codes, standards, and specifications; the loads and loading combinations; the design and analysis procedures; the structural acceptance criteria; the materials, quality control, and special construction techniques; and the testing and inservice surveillance requirements provide reasonable assurance that, in the event of winds, tornadoes, earthquakes, and various postulated events, seismic Category I foundations will withstand the specified design conditions
