Content:
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 ago (Ma) and continues to the present. Emphasis is placed on Quaternary-age features because evidence of surface deformation during the last approximately 2.6 million years generally indicates a potential for future surface deformation to occur. In order to assure that the potential for tectonic and non-tectonic surface deformation at a proposed site is evaluated, the application should describe the effect of each cause of surface deformation. The staff may determine that one or more causes of surface deformation are inconsequential or not applicable to the proposed site, or not a significant safety risk to the proposed facility, in which case further review of the cause of surface deformation as outlined in this SRP section is obviated. The staff should evaluate the application for the specific information identified below. The design description should include geologic, seismic, geophysical, and geotechnical information in Safety Analysis Report (SAR), Section 2.5.3 addressing the following specific topics that are the basis for the assessment of the potential for tectonic and non-tectonic surface deformation at the site: 1. Geologic, Seismic, and Geophysical Investigations. The reviewer assesses information provided by an applicant related to Quaternary tectonics, structural geology, stratigraphy, paleoseismology, geochronological methods used for age dating, and the geologic history of the site vicinity, area, and location. Staff reviews to ensure that the information is complete; acceptably considers other studies carried out in the same areas; and is supported by detailed investigations conducted by the applicant. For coastal and inland sites near large bodies of water, staff should confirm that similar detailed investigations are conducted by the applicant
