Draft Revision 4 - December 2012 The specific areas of review are as follows: 1. Seismic Analysis Methods. The information reviewed is similar to that described in Subsection I.1 of SRP Section 3.7.2 but as applied to seismic Category I subsystems. 2. Determination of Number of Earthquake Cycles. Criteria or procedures used to establish the number of earthquake cycles resulting from the seismic events and the maximum number of cycles for which applicable seismic Category I subsystems and components are designed are reviewed. 3. Procedures Used for Analytical Modeling. The information reviewed is similar to that described in Subsection I.3 of SRP Section 3.7.2 but as applied to seismic Category I subsystems. 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. 5. Analysis Procedure for Damping. The information reviewed is similar to that described in Subsection I.13 of SRP Section 3.7.2 but as applied to seismic Category I subsystems. 6. Three Components of Earthquake Motion. The information reviewed is similar to that described in Subsection I.6 of SRP Section 3.7.2 but as applied to seismic Category I subsystems. 7. Combination of Modal Responses. The information reviewed is similar to that described in Subsection I.7 of SRP Section 3.7.2 but as applied to seismic Category I subsystems. 8. Interaction of Other Systems With Seismic Category I Systems. The information reviewed is similar to that described in Subsection I.8 of SRP Section 3.7.2 but as applied to seismic Category I subsystems. 9. Multiply-Supported Equipment and Components with Distinct Inputs. The criteria and procedures for seismic analysis of equipment and components supported at different elevations within a building and between buildings with distinct inputs are reviewed. 10. Use of Equivalent Vertical Static Factors. The information
