Content:
a summary of the audit team’s activities and findings, assesses progress toward completion of the audit scope, and informs the applicant of the audit status. Any new technical issues and/or specific needs for additional information are communicated to the applicant. Informal discussions between audit team members and the applicant’s technical staff should be limited to exchanges of information. All Important audit findings and conclusions should be communicated to the applicant’s responsible manager by the NRC lead technical reviewer. 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 • Development of the ground motion time histories to match the design basis ground response spectrum. • Modeling of soil properties. • Modal properties of the structural models; confirmation of adequate refinement relative to the frequency content of the design basis ground response spectrum. 3.7.2-27 Revision 3 - March 2007 • Methodologies employed (computer codes, computer models) to conduct seismic analysis, including soil structure interaction (SSI) effects. • 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
