nd SSE, for all applicable damping values, are checked to ensure that the response spectra are in accordance with the acceptance criteria as given in subsection II.1.A.i. For the DC, the CSDRS for the OBE and SSE for applicable damping values are checked to ensure that the CSDRS are in accordance with the acceptance criteria as given in subsection II.1.A.ii. Any deviations from the acceptance criteria applicable to the development of the design response spectra or CSDRS that have not been adequately justified are identified, and the applicant is informed of the need for additional technical justification. B. Design Time History. Methods of defining the design ground motion time histories are reviewed to confirm that the acceptance criteria of subsection II.1.B of this SRP section are met. 2. Percentage of Critical Damping Values. The specific percentage of critical damping values for the OBE and SSE used in the analyses of Category I SSCs are checked to 3.7.1-19 Draft Revision 4 - December 2012 ensure that the damping values are in accordance with the acceptance criteria as given in subsection II.2 of this SRP section. Any differences in damping values that have not been adequately justified are identified, and the applicant is informed of the need for additional technical justification. 3. Supporting Media for Seismic Category I Structures. The description of the supporting media is reviewed to verify that sufficient information, as specified in the acceptance criteria of subsection II.3 of this SRP section, is included. 4. Review Considerations for DC and COL Applications. The information provided by the applicant to address the review considerations in the SRP acceptance criteria of subsection II.4 of this SRP section is reviewed. The review should conclude that the CSDRS envelop the site-specific GMRS. In addition, the review should conclude that the applicant addressed the identified COL action items. If compliance with these acceptance criteria are not
