Content:
e compliance characteristics of soil media, dynamic pressures, settlement due to earthquake and differ- ential movements at support points, penetrations, and entry points into structures provided with anchors are reviewed. 13. Methods for Seismic Analysis of Category I Concrete Dams The analytical methods and procedures that will be used for seismic analysis of Category I concrete dams are reviewed. The assumptions made, the boundary conditions used, the hydrodynamic effects considered, and the procedures by which strain-dependent material properties of foundation are incorporated in the analysis are reviewed. 3.7.3-2 Rev. 2 - August 1989 14. Methods for Seismic Analysis of Above-Ground Tanks For Category I above-ground tanks, the seismic criteria and methods that consider hydrodynamic forces, tank flexibility, soil-structure interaction, and other pertinent parameters are reviewed. II. ACCEPTANCE CRITERIA The acceptance criteria for the areas of review described in subsection I of this SRP section are given below. Other criteria which can be justified to be equivalent to or more conservative than the stated acceptance criteria may be used. The staff accepts the design of subsystems that are important to safety and must withstand the effects of earthquakes if the relevant requirements of General Design Criterion (GDC) 2 (Ref. 1) and Appendix A to 10 CFR Part 100 (Ref. 2) concerning material phenomena are complied with. The -relevant requirements of GDC 2 and Appendix A to 10 CFR Part 100 are: 1. General Design Criterion 2 - The design basis shall reflect appropriate consideration of the most severe earthquakes reported to have affected the | site and surrounding area with sufficient margin for the limited accuracy, quantity, and period of time in which historical data have been accumulated. 2. Appendix A to 10 CFR Part 100 - Two earthquake levels, the safe shutdown earthquake (SSE) and the operating basis earthquake (OBE), shall be considered in the design of
