eismic Analysis Methods. The seismic analysis methods are reviewed to determine that these are in accordance with the acceptance criteria of SRP Section 3.7.2, Subsection II.1. 3.7.3-11 Revision 4 – September 2013 2. Determination of Number of Earthquake Cycles. Criteria or procedures used to establish the number of earthquake cycles are reviewed to determine that they are in accordance with the acceptance criteria as given in Subsection II.2 of this SRP section. Justification for deviating from the acceptance criteria is requested from the applicant, as necessary. 3. Procedures Used for Analytical Modeling. The criteria and procedures used for modeling for the seismic subsystem analysis are reviewed to determine that these are in accordance with the acceptance criteria of SRP Section 3.7.2, Subsection II.3. 4. Basis for Selection of Frequencies. As applicable, criteria or procedures used to separate fundamental frequencies of components and equipment from the forcing frequencies of the support structure are reviewed to determine the acceptance criteria of Subsection II.4 of this SRP section are met. 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. 6. Three Components of Design Ground Motion: The procedures by which the three components of design ground motion are considered in determining the seismic response of subsystems are reviewed to determine if the acceptance criteria of SRP Section 3.7.2, Subsection II.6 are met. 7. Combination of Modal Responses. The procedures for combining modal responses are reviewed to determine if the acceptance criteria of SRP Section 3.7.2, Subsection II.7 are met when a response spectrum modal analysis method is used. 8. Interaction of Non-Seismic Category I Subsystems with Seismic Category I SSCs. The criteria used to design
