tion. 5. Analysis Procedure for Damping. The analysis procedure to account for damping in different elements of the model of a coupled system is reviewed to determine that it is in accordance with the acceptance criteria of SRP Section 3.7.2, subsection II.13. 3.7.3-10 Revision 3 - March 2007 6. Three Components of Earthquake Motion. The procedures by which the three components of earthquake motion are considered in determining the seismic response of subsystems are reviewed to determine compliance with the acceptance criteria of SRP Section 3.7.2, subsection II.6. 7. Combination of Modal Responses. The procedures for combining modal responses are reviewed to determine compliance with the acceptance criteria of SRP Section 3.7.2, subsection II.7 when a response spectrum modal analysis method is used. 8. Interaction of Other Systems with Seismic Category I Systems. The criteria used to design the interfaces between seismic Category I and non-seismic Category I systems are reviewed to determine compliance with the acceptance criteria of subsection II.8 of this SRP section. 9. Multiply-Supported Equipment and Components With Distinct Inputs. The criteria for the seismic analysis of multiply-supported equipment and components with distinct inputs are reviewed to determine that the criteria are in accordance with the acceptance criteria of subsection II.9 of this SRP section. 10. Use of Equivalent Vertical Static Factors. The procedures for the use of equivalent vertical static factors are reviewed to determine compliance with the acceptance criteria of SRP Section 3.7.2, subsection II.10. 11. Torsional Effects of Eccentric Masses. The procedures for seismic analysis of Category I subsystems are reviewed to determine compliance with the acceptance criteria of subsection II.11 of this SRP section. 12. Seismic Category I Buried Piping, Conduits, and Tunnels. The analysis procedures for seismic Category I buried piping, conduits, tunnels, and any other subsystems are
