Content:
a for each Category I structure is reviewed, including foundation embedment depth, depth of soil over bedrock, soil layering characteristics, design groundwater elevation, dimensions of the structural foundation, total structural height, and soil properties to permit evaluation of the applicability of finite-element or lumped-spring approaches for soil-structure interaction analysis. 4. Interface of Review Interfaces13 The ECGB also performs the following reviews under the SRP section indicated:14 1. Review of geological and seismological information to establish the 15 free-field ground motion is performed as described in SRP Sections 2.5.1 through 2.5.3. 2. The geotechnical parameters and methods employed in the analysis of free field soil 16 media and the soil properties are reviewed as described in SRP section 2.5.4. The results of the reviews for the operating basis earthquake (OBE) and the safe shutdown 17 earthquake (SSE) site-dependent free-field ground motion, soil properties, etc., are used as an 18 integral part of the seismic analysis review of Category I structures.19 For those areas of review identified above as being part of other SRP sections, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA The staff accepts the design of structures that are important to safety and that must withstand the effects of the earthquakes if the relevant requirements of General Design Criterion (GDC) 2 (Ref. 4) and Appendix A to 10 CFR Part 100 (Ref. 2) concerning natural phenomena are 20 21 complied with. The relevant requirements of GDC 2 and Appendix A to 10 CFR Part 100 are: 1A. For GDC 2 - The design basis shall reflect appropriate consideration of the most severe 22 earthquakes that have been historically reported for the site and surrounding area with sufficient margin for the limited accuracy, quantity, and period of time in which historical data have been
