Draft Revision 5 – August 2013 characterization investigations for this section of the Final Safety Analysis Report (FSAR), the applicant collects information related to surface deformation or subsidence due to faulting, dissolution of carbonate rock or salt, and diapirism. The primary purpose for conducting these investigations is to determine site suitability in regard to whether there is a potential for future surface deformation that may affect the design and operation of the proposed nuclear power plant. This SRP section provides criteria for the review and acceptance of the basic data- gathering process and findings and to support the staff’s assessment of the completeness of this information and the final safety decision to clearly establish whether there is a potential for surface deformation. NRC staff reviews the geologic, seismic, geophysical, and geotechnical information submitted by an applicant with respect to surface deformation (tectonic and non-tectonic) potential. The technical information derives from various investigations: work that the applicant initiates and completes for the preparation of the application and information from the published findings in peer reviewed scientific literature; information acquired from interviews with knowledgeable experts. The applicant reports this information in its application in each of three areas defined by radii of 40 km (25 mi), 8 km (5 mi), and 1 km (0.6 mi) around the site. The three areas correspond to, respectively, the site vicinity, site area, and site location. However, applicants need to report any significant neotectonic features found beyond these distance ranges, which have a potential to impact the site safety. As part of the process for review of potential surface deformation issues, staff evaluates the technical information provided by the applicant, with a focus on the Quaternary Period. The Quaternary Period is defined as the geologic period that began approximately 2.6 million years
