Content:
11. Torsional Effects of Eccentric Masses The criteria and procedures that are used to consider the torsional effects of eccentric masses in seismic subsystem analyses are reviewed. 12. Category I Buried Piping, Conduits, and Tunnels For Category I buried piping, conduits, tunnels, and auxiliary systems, the seismic criteria and methods which consider the compliance characteristics of soil media, dynamic pressures, settlement due to earthquake and differential 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. 3.7.3-3 DRAFT Rev. 3 - April 1996 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) 4 5 concerning material phenomena are complied with. The relevant requirements of GDC 2 and Appendix A to 10 CFR Part 100 are: 1A. General Design Criterion 2 - The design basis shall reflect appropriate consideration of 6 the most severe
