Content:
eismic Category I foundations is acceptable and meets the relevant requirements of 10 CFR 50.55a, 10 CFR Part 50, Appendix B, and GDCs 1, 2, 4, and 5. This conclusion is based on the following: 1. The applicant has met the requirements of 10 CFR 50.55a and GDC 1 with respect to ensuring that the Seismic Category I foundations are designed, fabricated, erected, constructed, tested, and inspected to quality standards commensurate with the safety functions to be performed by meeting the guidelines of RGs and industry standards indicated below. 2. The applicant has met the requirements of GDC 2 by designing the Seismic Category I foundation described in this section to withstand not only the most severe earthquake that has been established for the site with sufficient margin, but also 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 ensuring that the designs of Seismic Category I foundations are capable of withstanding the dynamic effects associated with missiles, pipe whipping, and discharging fluids. 3.8.5-16 Revision 3 - May 2010 4. The applicant has met the requirements of GDC 5 by demonstrating that SSCs are not shared between units or that, if shared, they have demonstrated that sharing will not impair their ability to perform their intended safety functions. 5. The applicant has met the requirements of 10 CFR Part 50, Appendix B because the quality assurance program provides adequate measures for implementing guidelines relating to structural design. 6. The criteria used in the analysis, design, and construction of all 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 NRC staff.
