Content:
set of requests for additional information, including any additional questions that may have been developed during the site visit, is formally transmitted to the applicant. The reviewer evaluates the applicant's response to the questions, prepares requests for additional clarifying information, and formulates positions that may agree or disagree with those of the applicant. These are formally transmitted to the applicant. The safety analysis report and amendments responding to the requests for additional information are reviewed to determine that the information pre- sented by the applicant is acceptable according to the criteria described in Section II (Acceptance Criteria) above. Based on information supplied by the applicant, obtained from site visits or from staff consultants or litera- ture sources, the reviewer independently identifies the relevant seismotec- tonic provinces, evaluates the capability of faults in the region, and deter- mines the earthquake potential for each province and each capable fault or tectonic structure using procedures noted in Section II (Acceptance Criteria) above. The reviewer evaluates the vibratory ground motion that the potential earthquakes could produce at the site and defines the safe shutdown earthquake and operating basis earthquake. IV. EVALUATION FINDINGS If the evaluation by the staff, on completion of the review of the geologic and seismologic aspects of the plant site, confirms that-the applicant has met the requirements or guidance of applicable portions of References 1 through 6, the conclusion in the SER states that the information provided and investigations performed support the applicant's conclusions regarding the seismic integrity of the subject nuclear power plant site. In addition to the conclusion, this section of the SER includes (1) definitions of tectonic provinces; (2) evaluations of the capability of geologic structures in the region; (3) determinations of the SSE earthquake(s) and free-field 2.5.2-9
