Draft Revision 4 - December 2012 The audit team’s activities should primarily focus on (a) review of pertinent technical information that the applicant referenced in its RAI responses; (b) confirmation, through review of formal calculations and design/analysis reports, that the applicant’s technical approach to seismic analysis of the Category I plant structures, as identified and discussed in the application, has been appropriately implemented; and (c) as applicable, discussions related to the staff’s independent confirmatory analyses. Topics of special interest include: 1. Development of the ground motion time histories to match the design basis ground response spectrum. 2. Modeling of soil properties. 3. Modal properties of the structural models; confirmation of adequate refinement relative to the frequency content of the design basis ground response spectrum. 4. Methodologies employed (computer codes, computer models) to conduct seismic analysis, including soil structure interaction (SSI) effects. 5. In-structure response spectra (3) Exit Meeting An exit meeting will be conducted at the conclusion of the audit, to discuss and summarize the audit findings, the unresolved RAIs, any new outstanding issues identified, and the applicant’s schedule for responding. One (1) hour is allotted for the exit meeting. (The LPM determines whether the exit meeting is a public meeting.) 7. Audit Report The NRC lead technical reviewer will prepare a summary of progress toward resolution of technical issues, and a description of any new outstanding technical issues that emerged during the audit. The LPM is responsible for preparation of an audit summary report. 8. Post-Audit Communications Review of the applicant's responses to the unresolved issues may necessitate additional meeting(s) or conference call(s) between the staff and the applicant, to obtain clarification of the responses. 9. Input to the Safety Evaluation Report
