Source Characterization (CEUS-SSC) model that integrate tectonic and seismic information from a broad range of sources. The U.S. Nuclear Regulatory Commission (NRC) staff will need to determine if new geologic information has been developed that affects the technical basis for a source-zone model. The significance of new information must be determined as part of a coordinated review of information in Section 2.5.2. 1. Geologic Setting The reviewer assesses information related to physiography, stratigraphy, lithology, and geomorphology, tectonic setting, faulting and folding characteristics of the region encompassing the site, and geologic history with special focus on features of Quaternary age. The reviewer confirms that the application provides adequate information at the site vicinity and area for assessment of local geologic conditions in comparison to the regional geologic topics addressed above as well as potential hazards related to natural phenomena including landslides and other mass-wasting phenomena;; displacement along growth faults; glacially-induced deformation; and potential for collapse or subsidence in areas underlain by limestone or other soluble rock (e.g., salt and gypsum). 2. Tectonic Framework The reviewer assesses information related to the tectonic framework of the region including structural geologic characteristics of the site and the region around the site, geologic and tectonic history; state of stress in the crust; nature and structure of the crust, and tectonic deformation features underlying the site and region, particularly those of Quaternary age, specifically including data on faulting and fault recurrence rates. The reviewer should also assess historical seismicity as it relates to the identification and characterization of geological structures. Seismicity and vibratory ground motion are primary review responsibilities addressed in SRP Section 2.5.2, which includes a detailed review of the seismic record and potential seismic
