dressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). 3.7.1-19 Revision 3 - March 2007 For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. The staff concludes that the seismic design parameters used in the design of plant SSCs are acceptable and meet the applicable requirements of 10 CFR 50, Appendix A, General Design Criterion (GDC) 2, 10 CFR Part 100, Subpart A and Subpart B, and 10 CFR Part 50, Appendix S. This conclusion is based on the following. The applicant has met the relevant requirements of GDC 2, 10 CFR Part 100, Subpart A and Subpart B, and 10 CFR Part 50, Appendix S by appropriate consideration for the most severe earthquake recorded for the site with an appropriate margin and considerations for two levels of earthquakes - the safe shutdown earthquake (SSE) and operating basis earthquake (OBE). The applicant has met these requirements by the use of the methods and procedures indicated below. The seismic design response spectra (OBE and SSE) applied in the design of seismic Category I SSCs meet or exceed the free-field response spectra provided in SRP Section 2.5.2. For the plant subject to Appendix S of 10 CFR Part 50, the horizontal component of the SSE ground motion in the free-field at the foundation level of the structures is based on an appropriate response
