R 100 Appendix A requirement that all safety-related SSCs be designed to remain functional and within applicable stress and deformation limits when subjected to an OBE. Acceptance of the exemption was predicated on the use of an alternative seismic analysis based entirely on the SSE and implementation of additional procedural requirements relating to a seismic event. The alternative analysis was determined to accomplish the design objectives of the OBE design analysis and meets the Commission-approved Staff recommendations discussed in SECY 93-087 (Reference 7).59 Any matters identified during the review of the SAR where additional information or justification are needed are included in the "Additional Technical Information Request." Such requests not only identify any portions of the seismic system analysis considered unacceptable without further justification, but also specify the changes that should be made in the SAR to meet the acceptance criteria. Subsequent amendments of the SAR received in response to these staff requests are reviewed for conformance with the staff positions. For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff’s evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site interface requirements, and combined license action items that are relevant to this SRP section.60 IV. EVALUATION FINDINGS (Combined for Sections 3.7.2 and 3.7.3) The reviewer verifies that sufficient information has been provided and that his evaluation is sufficiently complete and adequate to support conclusions of the following type, to be included in the staff's safety evaluation report: The staff concludes that the plant design is acceptable and meets the requirements of General Design Criterion 2 and Appendix A to 10 CFR Part 100. This conclusion is based on the following: The applicant
