ter the completion of this section. IV. EVALUATION FINDINGS (Combined for Sections 3.7.2 and 3.7.3) The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. The staff concludes that the plant design is acceptable and meets the requirements of 10 CFR Part 50, General Design Criterion (GDC) 2, 10 CFR Part 100, Subpart A (for applications received before January 10, 1997, and 10 CFR Part 100, Subpart B (for applications received on or after January 10, 1997). This conclusion is based on the following: The applicant has met the requirements of GDC 2 and 10 CFR Part 100, Appendix A or 10 CFR Part 50, Appendix S with respect to the capability of the structures to withstand the effects of earthquakes so that the design reflects: 1. Appropriate consideration for the most severe earthquake recorded for the site with an appropriate margin (GDC 2). Consideration of two levels of earthquakes (10 CFR Part 100, Appendix A or 10 CFR Part 50, Appendix S ), 3.7.2-22 Revision 3 - March 2007 2. Appropriate combination of the effects of normal and accident conditions with the effect of the natural phenomena, 3. The importance of the safety functions to be performed (GDC 2), and 4. The use of a suitable dynamic analysis or a suitable qualification test to demonstrate that structures, systems, and components (SSCs) can withstand the seismic and other concurrent loads, except where it can be demonstrated that the use of an equivalent static load method provides adequate consideration (10 CFR Part 100, Appendix A or 10 CFR Part 50, Appendix S ). The applicant has met the requirements of item 1 listed above by use of the acceptable seismic design parameters as per SRP Section 3.7.1. The combination of earthquake- resultant loads with those resulting from normal and
