e site region. The reviewer also evaluates investigative techniques employed by the applicant for defining the zones to ascertain whether they are consistent with state-of-the-art practices, and staff may ask technical experts to review specific aspects of the investigative program. The reviewer analyzes results of the investigations to determine whether analysis of Quaternary deformation at the outer limits of the 40 km (25 mi) radius (i.e., the site vicinity) zone are appropriately conservative. 8. Potential for Surface Tectonic Deformation of the Site. If detailed investigations for the proposed commercial nuclear power plant reveal a potential for surface or near-surface deformation at the site, staff recommends that an alternative location be considered for the proposed plant. No commercial nuclear power plant has ever been constructed on a known capable tectonic deformation feature, and it is questionable whether it may be feasible to design for surface or near-surface tectonic displacements with any degree of confidence that safety-related plant features would remain intact and functional if displacements were to occur. If it becomes feasible in the future to design for surface faulting with confidence that safety-related plant features would remain intact and functional, it will be necessary for an applicant to present the design basis for surface faulting and supporting data in a very high degree of detail. 2.5.3-16 Revision 4 - March 2007 Review Procedures Specific to 10 CFR Part 52 Application Type 1. Early Site Permit Reviews Subpart A to 10 CFR Part 52 specifies the requirements and procedures applicable to the Commission’s review of an ESP application for approval of a proposed site. Information required in an ESP application includes number, type, and thermal power level of the facilities for which the site may be used; types of cooling systems used; and description of geologic, seismic, geophysical, geotechnical, and hydrologic characteristics of
